Connect the cut-off lead wires with crimp contact, etc, put the closed end side upward and then  
apply a water-cut method, otherwise a leak or production of fire is caused at the users’ side.  
Insulating  
measures  
When performing repairs using a gas burner, replace the refrigerant with nitrogen gas because  
the oil that coats the pipes may otherwise burn.  
When repairing the refrigerating cycle, take the following measures.  
1) Be attentive to fire around the cycle.  
When using a gas stove, etc, be sure to put out fire before work; otherwise the oil mixed with  
refrigerant gas may catch fire.  
2) Do not use a welder in the closed room.  
No fire  
When using it without ventilation, carbon monoxide poisoning may be caused.  
3) Do not bring inflammables close to the refrigerant cycle, otherwise fire of the welder may catch  
the inflammables.  
– 7 –  
The refrigerant used by this air conditioner is the R410A.  
Check the used refrigerant name and use tools and materials of the parts which match with it.  
For the products which use R410A refrigerant, the refrigerant name is indicated at a position on  
the outdoor unit where is easy to see.  
To prevent miss-charging, the route of the service port is changed from one of the former R22.  
For an air conditioner which uses R410A, never use other refrigerant than R410A.  
For an air conditioner which uses other refrigerant (R22, etc.), never use R410A.  
If different types of refrigerant are mixed, abnormal high pressure generates in the refrigerating  
cycle and an injury due to breakage may be caused.  
Do not charge refrigerant additionally.  
If charging refrigerant additionally when refrigerant gas leaks, the refrigerant composition in the  
refrigerating cycle changes resulted in change of air conditioner characteristics or refrigerant over  
the specified standard amount is charged and an abnormal high pressure is applied to the inside  
of the refrigerating cycle resulted in cause of breakage or injury.  
Therefore if the refrigerant gas leaks, recover the refrigerant in the air conditioner, execute  
vacuuming, and then newly recharge the specified amount of liquid refrigerant.  
In this time, never charge the refrigerant over the specified amount.  
Refrigerant  
When recharging the refrigerant in the refrigerating cycle, do not mix the refrigerant or air other  
than R410A into the specified refrigerant.  
If air or others is mixed with the refrigerant, abnormal high pressure generates in the refrigerating  
cycle resulted in cause of injury due to breakage.  
After installation work, check the refrigerant gas does not leak.  
If the refrigerant gas leaks in the room, poisonous gas generates when gas touches to fire such  
as fan heater, stove or cocking stove though the refrigerant gas itself is innocuous.  
Never recover the refrigerant into the outdoor unit.  
When the equipment is moved or repaired, be sure to recover the refrigerant with recovering device.  
The refrigerant cannot be recovered in the outdoor unit; otherwise a serious accident such as  
breakage or injury is caused.  
After repair work, surely assemble the disassembled parts, and connect and lead the removed  
wires as before.  
Perform the work so that the cabinet or panel does not catch the inner wires.  
If incorrect assembly or incorrect wire connection was done, a disaster such as a leak or fire is  
caused at user’s side.  
Assembly/  
Cabling  
After the work has finished, be sure to use an insulation tester set (500V Megger) to check the  
resistance is 2MΩ or more between the charge section and the non-charge metal section  
(Earth position).  
Insulator  
check  
If the resistance value is low, a disaster such as a leak or electric shock is caused at user’s side.  
When the refrigerant gas leaks during work, execute ventilation.  
If the refrigerant gas touches to a fire, poisonous gas generates.  
A case of leakage of the refrigerant and the closed room full with gas is dangerous because a  
shortage of oxygen occurs. Be sure to execute ventilation.  
Ventilation  
When the refrigerant gas leaks, find up the leaked position and repair it surely.  
If the leaked position cannot be found up and the repair work is interrupted, pump-down and  
tighten the service valve, otherwise the refrigerant gas may leak into the room.  
The poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove  
though the refrigerant gas itself is innocuous.  
When installing equipment which includes a large amount of charged refrigerant such as a multi  
air conditioner in a sub-room, it is necessary that the density does not the limit even if the  
refrigerant leaks.  
If the refrigerant leaks and exceeds the limit density, an accident of shortage of oxygen is caused.  
Tighten the flare nut with a torque wrench in the specified manner.  
Excessive tighten of the flare nut may cause a crack in the flare nut after a long period, which may  
result in refrigerant leakage.  
Compulsion  
Nitrogen gas must be used for the airtight test.  
The charge hose must be connected in such a way that it is not slack.  
For the installation/moving/reinstallation work, follow to the Installation Manual.  
If an incorrect installation is done, a trouble of the refrigerating cycle, water leak, electric shock or  
fire is caused.  
– 8 –  
Once the repair work has been completed, check for refrigerant leaks, and check the insulation  
resistance and water drainage.  
Then perform a trial run to check that the air conditioner is running properly.  
After repair work has finished, check there is no trouble. If check is not executed, a fire, electric  
shock or injury may be caused. For a check, turn off the power breaker.  
Check after  
repair  
After repair work (installation of front panel and cabinet) has finished, execute a test run to check  
there is no generation of smoke or abnormal sound.  
If check is not executed, a fire or an electric shock is caused. Before test run, install the front  
panel and cabinet.  
Check the following matters before a test run after repairing piping.  
• Connect the pipes surely and there is no leak of refrigerant.  
• The valve is opened.  
Running the compressor under condition that the valve closes causes an abnormal high  
pressure resulted in damage of the parts of the compressor and etc. and moreover if there is  
leak of refrigerant at connecting section of pipes, the air is suctioned and causes further  
abnormal high pressure resulted in burst or injury.  
Do not  
operate the  
unit with the  
valve closed.  
Only a qualified installer (∗1) or qualified service person (∗1) is allowed to relocate the air  
conditioner. It is dangerous for the air conditioner to be relocated by an unqualified individual  
since a fire, electric shocks, injury, water leakage, noise and/or vibration may result.  
Check the following items after reinstallation.  
1) The earth wire is correctly connected.  
2) The power cord is not caught in the product.  
3) There is no inclination or unsteadiness and the installation is stable.  
If check is not executed, a fire, an electric shock or an injury is caused.  
Check after  
reinstallation  
When carrying out the pump-down work shut down the compressor before disconnecting the  
refrigerant pipe.  
Disconnecting the refrigerant pipe with the service valve left open and the compressor still  
operating will cause air, etc. to be sucked in, raising the pressure inside the refrigeration cycle to  
an abnormally high level, and possibly resulting in reputing, injury, etc.  
When the service panel of the outdoor unit is to be opened in order for the compressor or the  
area around this part to be repaired immediately after the air conditioner has been shut down, set  
the circuit breaker to the OFF position, and then wait at least 10 minutes before opening the  
service panel.  
If you fail to heed this warning, you will run the risk of burning yourself because the compressor  
pipes and other parts will be very hot to the touch. In addition, before proceeding with the repair  
work, wear the kind of insulated heat-resistant gloves designed to protect electricians.  
When the service panel of the outdoor unit is to be opened in order for the fan motor, reactor,  
Cooling check inverter or the areas around these parts to be repaired immediately after the air conditioner has  
been shut down, set the circuit breaker to the OFF position, and then wait at least 10 minutes  
before opening the service panel.  
If you fail to heed this warning, you will run the risk of burning yourself because the fan motor,  
reactor, inverter heat sink and other parts will be very hot to the touch.  
In addition, before proceeding with the repair work, wear the kind of insulated heat-resistant  
gloves designed to protect electricians.  
Only a qualified installer (∗1) or qualified service person (∗1) is allowed to install the air  
conditioner. If the air conditioner is installed by an unqualified individual, a fire, electric shocks,  
injury, water leakage, noise and/or vibration may result.  
Before starting to install the air conditioner, read carefully through the Installation Manual, and  
follow its instructions to install the air conditioner.  
Do not install the air conditioner in a location that may be subject to a risk of expire to a  
combustible gas.  
If a combustible gas leaks and becomes concentrated around the unit, a fire may occur.  
Install the indoor unit at least 2.5 m above the floor level since otherwise the users may injure  
themselves or receive electric shocks if they poke their fingers or other objects into the indoor unit  
while the air conditioner is running.

New Refrigerant (R410A)  
This air conditioner adopts a new HFC type refrigerant (R410A) which does not deplete the ozone layer.  
1. Safety Caution Concerned to New Refrigerant  
The pressure of R410A is high 1.6 times of that of the former refrigerant (R22).  
Accompanied with change of refrigerant, the refrigerating oil has been also changed.  
Therefore, be sure that water, dust, the former refrigerant or the former refrigerating oil is not mixed into the  
refrigerating cycle of the air conditioner with new refrigerant during installation work or service work.  
If an incorrect work or incorrect service is performed, there is a possibility to cause a serious accident.  
Use the tools and materials exclusive to R410A to purpose a safe work.  
2. Cautions on Installation/Service  
1) Do not mix the other refrigerant or refrigerating oil.  
For the tools exclusive to R410A, shapes of all the joints including the service port differ from those of  
the former refrigerant in order to prevent mixture of them.  
2) As the use pressure of the new refrigerant is high, use material thickness of the pipe and tools which are  
specified for R410A.  
3) In the installation time, use clean pipe materials and work with great attention so that water and others  
do not mix in because pipes are affected by impurities such as water, oxide scales, oil, etc.  
Use the clean pipes.  
Be sure to brazing with flowing nitrogen gas. (Never use gas other than nitrogen gas.)  
4) For the earth protection, use a vacuum pump for air purge.  
5) R410A refrigerant is azeotropic mixture type refrigerant.  
Therefore use liquid type to charge the refrigerant. (If using gas for charging, composition of the  
refrigerant changes and then characteristics of the air conditioner change.)  
3. Pipe Materials  
For the refrigerant pipes, copper pipe and joints are mainly used.  
It is necessary to select the most appropriate pipes to conform to the standard.  
Use clean material in which impurities adhere inside of pipe or joint to a minimum.  
1) Copper pipe  
<Piping>  
The pipe thickness, flare finishing size, flare nut and others differ according to a refrigerant type.  
When using a long copper pipe for R410A, it is recommended to select “Copper or copper-base pipe  
without seam” and one with bonded oil amount 40mg/10m or less.  
Also do not use crushed, deformed, discolored (especially inside) pipes.  
(Impurities cause clogging of expansion valves and capillary tubes.)  
<Flare nut>  
Use the flare nuts which are attached to the air conditioner unit.  
2) Joint  
The flare joint and socket joint are used for joints of the copper pipe.  
The joints are rarely used for installation of the air conditioner.  
However clear impurities when using them.

4. Tools  
1. Required Tools for R410A  
Mixing of different types of oil may cause a trouble such as generation of sludge, clogging of capillary,  
etc. Accordingly, the tools to be used are classified into the following three types.  
1) Tools exclusive for R410A (Those which cannot be used for conventional refrigerant (R22))  
2) Tools exclusive for R410A, but can be also used for conventional refrigerant (R22)  
3) Tools commonly used for R410A and for conventional refrigerant (R22)  
The table below shows the tools exclusive for R410A and their interchangeability.

margin is necessary. For this adjustment, a copper pipe gauge, etc. are necessary.  
General tools (Conventional tools can be used.)  
In addition to the above exclusive tools, the following equipments which serve also for R22 are necessary  
as the general tools.  
1) Vacuum pump. Use vacuum pump by  
attaching vacuum pump adapter.  
2) Torque wrench  
3) Pipe cutter

6. REFRIGERANT R410A  
This air conditioner adopts the new refrigerant HFC  
(R410A) which does not damage the ozone layer.  
6. When an air conditioning system charged with a  
large volume of refrigerant is installed in a small  
room, it is necessary to exercise care so that,  
even when refrigerant leaks, its concentration  
does not exceed the marginal level.  
The working pressure of the new refrigerant R410A  
is 1.6 times higher than conventional refrigerant  
(R22). The refrigerating oil is also changed in  
accordance with change of refrigerant, so be careful  
that water, dust, and existing refrigerant or  
refrigerating oil are not entered in the refrigerant  
cycle of the air conditioner using the new refrigerant  
during installation work or servicing time.  
If the refrigerant gas leakage occurs and its  
concentration exceeds the marginal level, an  
oxygen starvation accident may result.  
7. Be sure to carry out installation or removal  
according to the installation manual.  
The next section describes the precautions for air  
conditioner using the new refrigerant.  
Improper installation may cause refrigeration  
trouble, water leakage, electric shock, fire, etc.  
Conforming to contents of the next section together  
with the general cautions included in this manual,  
perform the correct and safe work.  
8. Unauthorized modifications to the air conditioner  
may be dangerous. If a breakdown occurs  
please call a qualified air conditioner technician  
or electrician.  
Improper repair may result in water leakage,  
electric shock and fire, etc.  
6-1. Safety During Installation/Servicing  
As R410A’s pressure is about 1.6 times higher than  
that of R22, improper installation/servicing may  
cause a serious trouble. By using tools and  
materials exclusive for R410A, it is necessary to  
carry out installation/servicing safely while taking  
the following precautions into consideration.  
6-2. Refrigerant Piping Installation  
6-2-1. Piping Materials and Joints Used  
For the refrigerant piping installation, copper pipes  
and joints are mainly used.  
1. Never use refrigerant other than R410A in an air  
conditioner which is designed to operate with  
R410A.  
Copper pipes and joints suitable for the refrigerant  
must be chosen and installed.  
Furthermore, it is necessary to use clean copper  
pipes and joints whose interior surfaces are less  
affected by contaminants.  
If other refrigerant than R410A is mixed,  
pressure in the refrigeration cycle becomes  
abnormally high, and it may cause personal  
injury, etc. by a rupture.  
1. Copper Pipes  
2. Confirm the used refrigerant name, and use  
tools and materials exclusive for the refrigerant  
R410A.  
It is necessary to use seamless copper pipes  
which are made of either copper or copper alloy  
and it is desirable that the amount of residual oil  
is less than 40 mg/10 m.  
The refrigerant name R410A is indicated on the  
visible place of the outdoor unit of the air  
conditioner using R410A as refrigerant.  
Do not use copper pipes having a collapsed,  
deformed or discolored portion (especially on  
the interior surface).  
To prevent mischarging, the diameter of the  
service port differs from that of R22.  
Otherwise, the expansion valve or capillary tube  
may become blocked with contaminants.  
3. If a refrigeration gas leakage occurs during  
installation/servicing, be sure to ventilate fully.  
As an air conditioner using R410A incurs pres-  
sure higher than when using R22, it is necessary  
to choose adequate materials.  
If the refrigerant gas comes into contact with fire,  
a poisonous gas may occur.  
4. When installing or removing an air conditioner,  
do not allow air or moisture to remain in the  
refrigeration cycle.  
Thicknesses of copper pipes used with R410A  
are as shown in Table 6-2-1. Never use copper  
pipes thinner than 0.8mm even when it is avail-  
able on the market.  
Otherwise, pressure in the refrigeration cycle  
may become abnormally high so that a rupture  
or personal injury may be caused.  
5. After completion of installation work, check to  
make sure that there is no refrigeration gas  
leakage.  
NOTE  
Refer to the “6-6. Instructions for Re-use Piping  
of R22 or R407C”.  
If the refrigerant gas leaks into the room, coming  
into contact with fire in the fan-driven heater,  
space heater, etc., a poisonous gas may occur.

1. Joints  
For copper pipes, flare joints or socket joints are used. Prior to use, be sure to remove all contaminants.  
a) Flare Joints  
Flare joints used to connect the copper pipes cannot be used for pipings whose outer diameter exceeds  
20 mm. In such a case, socket joints can be used.  
Sizes of flare pipe ends, flare joint ends and flare nuts are as shown in Tables 6-2-3 to 6-2-5 below.  
b) Socket Joints  
Socket joints are such that they are brazed for connections, and used mainly for thick pipings whose  
diameter is larger than 20 mm. Thicknesses of socket joints are as shown in Table 6-2-2.

6-2-2. Processing of Piping Materials  
When performing the refrigerant piping installation, care should be taken to ensure that water or dust does not  
enter the pipe interior, that no other oil other than lubricating oils used in the installed air conditioner is used,  
and that refrigerant does not leak.  
When using lubricating oils in the piping processing, use such lubricating oils whose water content has been  
removed. When stored, be sure to seal the container with an airtight cap or any other cover.  
1. Flare Processing Procedures and Precautions  
a) Cutting the Pipe  
By means of a pipe cutter, slowly cut the pipe so that it is not deformed.  
b) Removing Burrs and Chips  
If the flared section has chips or burrs, refrigerant leakage may occur.  
Carefully remove all burrs and clean the cut surface before installation.  
– 39 –  
c) Insertion of Flare Nut  
d) Flare Processing  
Make certain that a clamp bar and copper pipe have been cleaned.  
By means of the clamp bar, perform the flare processing correctly.  
Use either a flare tool for R410A or conventional flare tool.

2. Flare Connecting Procedures and Precautions  
a) Make sure that the flare and union portions do not have any scar or dust, etc.  
b) Correctly align the processed flare surface with the union axis.  
c) Tighten the flare with designated torque by means of a torque wrench.  
The tightening torque for R410A is the same as that for conventional R22.  
Incidentally, when the torque is weak, the gas leakage may occur.  
When it is strong, the flare nut may crack and may be made non-removable.  
When choosing the tightening torque, comply with values designated by manufacturers.  
Table 6-2-6 shows reference values.  
NOTE  
When applying oil to the flare surface, be sure to use oil designated by the manufacturer.  
If any other oil is used, the lubricating oils may deteriorate and cause the compressor to burn out.

6-4. Recharging of Refrigerant  
When it is necessary to recharge refrigerant, charge the specified amount of new refrigerant according to the  
following steps.  
Recover the refrigerant, and check no refrigerant  
remains in the equipment.  
When the compound gauge’s pointer has indicated  
–0.1 Mpa (–76 cmHg), place the handle Low in the  
fully closed position, and turn off the vacuum  
pump’s power switch.  
Connect the charge hose to packed valve service port  
at the outdoor unit’s gas side.  
Keep the status as it is for 1 to 2 minutes, and  
ensure that the compound gauge’s pointer  
does not return.  
Connect the charge hose of the vacuum pump adapter.  
Open fully both packed valves at liquid and gas sides.  
Set the refrigerant cylinder to the electronic balance,  
connect the connecting hose to the cylinder and  
the connecting port of the electronic balance, and  
charge liquid refrigerant.  
Place the handle of the gauge manifold Low in the fully  
opened position, and turn on the vacuum pump’s power switch.  
Then, evacuating the refrigerant in the cycle.  
(For refrigerant charging, see the figure below.)  
1) Never charge refrigerant exceeding the specified amount.  
2) If the specified amount of refrigerant cannot be charged, charge refrigerant bit by bit in COOL mode.  
3) Do not carry out additional charging.  
When additional charging is carried out if refrigerant leaks, the refrigerant composition changes in the refrigera-  
tion cycle, that is characteristics of the air conditioner changes, refrigerant exceeding the specified amount is  
charged, and working pressure in the refrigeration cycle becomes abnormally high pressure, and may cause a  
rupture or personal injury.

1) Be sure to make setting so that liquid can be charged.  
2) When using a cylinder equipped with a siphon, liquid can be charged without turning it upside down.  
It is necessary for charging refrigerant under condition of liquid because R410A is mixed type of refrigerant.  
Accordingly, when charging refrigerant from the refrigerant cylinder to the equipment, charge it turning the  
cylinder upside down if cylinder is not equipped with siphon.

R410A refrigerant is HFC mixed refrigerant.  
Therefore, if it is charged with gas, the composition

6-5. Brazing of Pipes  
6-5-1. Materials for Brazing  
1. Silver brazing filler  
1) Phosphor bronze brazing filler tends to react with  
sulfur and produce a fragile compound water  
solution, which may cause a gas leakage.  
Therefore, use any other type of brazing filler at  
a hot spring resort, etc., and coat the surface  
with a paint.  
Silver brazing filler is an alloy mainly composed  
of silver and copper.  
It is used to join iron, copper or copper alloy, and  
is relatively expensive though it excels in  
solderability.  
2) When performing brazing again at time of  
servicing, use the same type of brazing filler.  
2. Phosphor bronze brazing filler  
6-5-2. Flux  
Phosphor bronze brazing filler is generally used  
to join copper or copper alloy.  
1. Reason why flux is necessary  
• By removing the oxide film and any foreign  
matter on the metal surface, it assists the flow  
of brazing filler.  
3. Low temperature brazing filler  
Low temperature brazing filler is generally called  
solder, and is an alloy of tin and lead.  
• In the brazing process, it prevents the metal  
surface from being oxidized.  
Since it is weak in adhesive strength, do not use  
it for refrigerant pipes.  
• By reducing the brazing filler's surface tension,  
the brazing filler adheres better to the treated  
metal.  
– 43 –  
2. Characteristics required for flux  
6-5-3. Brazing  
• Activated temperature of flux coincides with  
the brazing temperature.  
As brazing work requires sophisticated techniques,  
experiences based upon a theoretical knowledge, it  
must be performed by a person qualified.  
• Due to a wide effective temperature range, flux  
is hard to carbonize.  
In order to prevent the oxide film from occurring in  
the pipe interior during brazing, it is effective to  
proceed with brazing while letting dry Nitrogen gas  
flow.  
• It is easy to remove slag after brazing.  
• The corrosive action to the treated metal and  
brazing filler is minimum.  
• It excels in coating performance and is  
harmless to the human body.  
Never use gas other than Nitrogen gas.  
1. Brazing method to prevent oxidation  
As the flux works in a complicated manner as  
described above, it is necessary to select an  
adequate type of flux according to the type and  
shape of treated metal, type of brazing filler and  
brazing method, etc.  
1) Attach a reducing valve and a flow-meter to  
the Nitrogen gas cylinder.  
2) Use a copper pipe to direct the piping  
material, and attach a flow-meter to the  
cylinder.  
3. Types of flux  
• Noncorrosive flux  
Generally, it is a compound of borax and boric  
acid.  
3) Apply a seal onto the clearance between the  
piping material and inserted copper pipe for  
Nitrogen in order to prevent backflow of the  
Nitrogen gas.  
It is effective in case where the brazing  
temperature is higher than 800°C.  
4) When the Nitrogen gas is flowing, be sure to  
keep the piping end open.  
• Activated flux  
Most of fluxes generally used for silver brazing  
are this type.  
5) Adjust the flow rate of Nitrogen gas so that it  
is lower than 0.05 m³/Hr or 0.02 MPa  
It features an increased oxide film removing  
capability due to the addition of compounds  
such as potassium fluoride, potassium chloride  
and sodium fluoride to the borax-boric acid  
compound.  
(0.2kgf/cm²) by means of the reducing valve.  
6) After performing the steps above, keep the  
Nitrogen gas flowing until the pipe cools down  
to a certain extent (temperature at which  
pipes are touchable with hands).  
4. Piping materials for brazing and used  
brazing filler/flux  
7) Remove the flux completely after brazing.

Therefore, use a flux which does not contain  
chlorine.

6-6. Instructions for Re-use Piping of R22 or R407C  
6. Check the oil when the existing air conditioner was  
Instruction of Works:  
removed after refrigerant had been recovered.  
In this case, if the oil is judged as clearly different  
compared with normal oil  
The existing R22 and R407C piping can be  
reused for our digital inverter R410A products  
installations.  
• The refrigerator oil is copper rust green :  
There is possibility that moisture is mixed with the  
oil and rust generates inside of the pipe.  
• There is discolored oil, a large quantity of the  
remains, or bad smell.  
NOTE)  
Confirmation of existence of scratch or dent of the  
former pipes to be applied and also confirmation of  
reliability of the pipe strength are conventionally  
referred to the local site.  
• A large quantity of sparkle remained wear-out  
powder is observed in the refrigerator oil.  
If the definite conditions can be cleared,  
it is possible to update the existing R22 and  
R407C pipes to those for R410A models.  
7. The air conditioner which compressor was ex-  
changed due to a faulty compressor.  
When the discolored oil, a large quantity of the  
remains, mixture of foreign matter, or a large  
quantity of sparkle remained wear-out powder is  
observed, the cause of trouble will occur.  
6-6-1. Basic Conditions Needed to Reuse the  
Existing Pipe  
Check and observe three conditions of the refrigerant  
piping works.  
8. Installation and removal of the air conditioner are  
repeated with temporary installation by lease and  
etc.  
9. In case that type of the refrigerator oil of the  
existing air conditioner is other than the following oil  
(Mineral oil), Suniso, Freol-S, MS (Synthetic oil),  
alkyl benzene (HAB, Barrel-freeze), ester series,  
PVE only of ether series.  
1. Dry  
(There is no moisture inside of the pipes.)  
2. Clean (There is no dust inside of the pipes.)  
3. Tight (There is no refrigerant leak.)  
6-6-2. Restricted Items to Use the Existing Pipes  
In the following cases, the existing pipes cannot be  
reused as they are. Clean the existing pipes or ex-  
change them with new pipes.  
• Winding-insulation of the compressor may  
become inferior.  
NOTE)  
1. When a scratch or dent is heavy, be sure to use the  
new pipes for the works.  
The above descriptions are results of confirmation by  
our company and they are views on our air  
conditioners, but they do not guarantee the use of the  
existing pipes of the air conditioner that adopted  
R410A in other companies.  
2. When the thickness of the existing pipe is thinner  
than the specified “Pipe diameter and thickness” be  
sure to use the new pipes for the works.  
• The operating pressure of R410A is high  
(1.6 times of R22 and R407C). If there is a scratch  
or dent on the pipe or thinner pipe is used, the  
pressure strength is poor and may cause break-  
age of the pipe at the worst.  
6-6-3. Branching Pipe for Simultaneous  
Operation System  
• In the concurrent twin system, when TOSHIBA-  
specified branching pipe is used, it can be reused.

6-6-6. Handling of Existing Pipe  
6-6-7. Recovery Method of Refrigerant  
When using the existing pipe, carefully check it for  
the following:  
• Use the refrigerant recovery switch SW801 on the  
P.C. board of the outdoor unit to recover refrigerant  
when the indoor unit or outdoor unit is moved.  
• Wall thickness (within the specified range)  
• Scratches and dents  
Procedure  
• Water, oil, dirt, or dust in the pipe  
• Flare looseness and leakage from welds  
• Deterioration of copper pipe and heat insulator  
1. Turn on the power of the air conditioner.  
2. Select the FAN mode for indoor unit operation  
with the remote controller.  
3. Set SW804 on the P.C. board of the outdoor unit  
to all OFF, and then push SW801 for one second  
or more.  
Cautions for using existing pipe  
• Do not reuse the flare to prevent gas leak.  
Replace it with the supplied flare nut and then  
process it to a flare.  
The air conditioner enters the forced cooling  
mode for up to 10 minutes.  
• Blow nitrogen gas or use an appropriate means to  
keep the inside of the pipe clean.  
Operation or handling the valve to recover  
refrigerant during this time period.  
If discolored oil or much residue is discharged,  
wash the pipe.  
4. Upon completion of refrigerant recovery, close  
the valve and push SW801 for at least one  
second to stop operation.  
• Check welds, if any, on the pipe for gas leak.  
When the pipe corresponds to any of the following,  
do not use it. Install a new pipe instead.  
5. Turn off the power.  
• The pipe has been open (disconnected from indoor  
unit or outdoor unit) for a long period.  
• The pipe has been connected to an outdoor unit  
that does not use refrigerant R22, R410A or R407C.

7-2. Outline of Main Controls  
1. PMV (Pulse Motor Valve) control  
1) PMV is controlled between 30 and 500 pulses during operation.  
2) In cooling operation, PMV is usually controlled with the temperature difference between TS sensor and  
TC sensor aiming 1 to 4K as the target value.  
3) In heating operation, PMV is usually controlled with the temperature difference between TS sensor and  
TE sensor aiming –1 to 4K as the target value.  
4) When the cycle excessively heated in both cooling and heating operation, PMV is controlled by TD  
sensor. The target value is usually 91°C in cooling operation and 96°C in heating operation.  
REQUIREMENT  
A sensor trouble may cause a liquid back-flow or abnormal overheat resulting in excessive shortening of the  
compressor life. In a case of trouble on the compressor, be sure to check there is no error in the resistance  
value or the refrigerating cycle of each sensor after repair and then start the operation.  
2. Discharge temperature release control  
1) When the discharge temperature did not fall or the discharge temperature rapidly went up by PMV  
control, this control lowers the operation frequency. It subdivides the frequency control up to 0.6Hz to  
stabilize the cycle.  
2) When the discharge temperature detected an abnormal stop zone, the compressor stops and then  
restarts after 2 minutes 30 seconds.  
The error counting is cleared when the operation continued for 10 minutes. If the error is detected by  
4 times without clearing, the error is determined and restarting is not performed.  
∗ The cause is considered as excessively little amount of refrigerant, PMV error or clogging of the cycle.  
3) For displayed contents of error, confirm on the check code list.

4. Coil heating control  
1) This control function heats the compressor by turning on the stopped compressor instead of a case heater.  
It purposes to prevent stagnation of the refrigerant inside of the compressor.  
2) As usual, turn on power of the compressor for the specified time before a test run after installation;  
otherwise a trouble of the compressor may be caused.  
As same as a test run, it is recommended to turn on power of the compressor beforehand when starting  
operation after power of the compressor has been interrupted and left as it is for a long time.  
3) A judgment for electricity is performed by TD and TO sensors.  
If TO sensor is defective, a backup control is automatically performed by TE sensor.  
For a case of defective TO sensor, judge it with outdoor LED display.  
4) For every model, the power is turned off when TD is 30°C or more.

REQUIREMENT  
While heating the coil, the power sound may be heard. However it is not a trouble.  
5. Short intermittent operation preventive control  
1) For 3 to 10 minutes after operation start, in some cases, the compressor does not stop to protect the  
compressor even if receiving the thermostat-OFF signal from indoor.  
However it is not abnormal status. (The operation continuance differs according to the operation status.)  
2) When the operation stops by the remote controller, the operation does not continue.  
6. Current release control  
No. of revolutions of the compressor is controlled by AC current value detected by T611 on the outdoor P.C.  
board so that the input current of the inverter does not exceed the specified value.

8. Over-current protective control  
1) When the over-current protective circuit detected an abnormal current, stop the compressor.  
2) The compressor restarts after 2 minutes 30 seconds setting [1] as an error count.  
3) When the error count [8] was found, determine an error and restart operation is not performed.  
4) For the error display contents, confirm on the check code list.  
9. High-pressure release control  
1) The operation frequency is controlled to restrain abnormal rising of high pressure by TL sensor in  
cooling operation and TC sensor in heating operation.  
2) When TL sensor in cooling operation or TC sensor in heating operation detects abnormal temperature of  
the stop zone, stop the compressor and the error count becomes +1.  
3) When the compressor stopped with 2), the operation restarts from the point of the normal operation  
zone (e point or lower) where it returned after 2 minutes 30 seconds.  
4) The error count when the compressor stopped with 2) is cleared after the operation continued for  
10 minutes.  
If the error count becomes [10] without clearing, the error is determined and reactivation is not performed.  
5) For the error display contents, confirm on the check code list.

10. Defrost control  
1) In heating operation, defrost operation is performed when TE sensor satisfies any condition in A zone to  
D zone.  
2) During defrosting operation, it finishes if TE sensor continued 12°C or higher for 3 seconds or continued  
7°C ≤ TE < 12°C for 1 minute.  
The defrost operation also finishes when it continued for 10 minutes even if TE sensor temperature was  
7°C or lower.  
3) After defrost operation was reset, the compressor stopped for approx. 40 seconds and then the heating  
operation starts.

1) This section describes the diagnostic method for each check code displayed on the remote controller.  
2) In some cases, a check code indicates multiple symptoms.  
In this case, confirm LED display on the outdoor P.C. board to narrow the contents to be confirmed.  
3) The check code on the remote controller is displayed only when the same error occurred continuously by  
multiple times while LED of the outdoor P.C. board displays even an error which occurred once.  
Therefore the display on the remote controller may differ from that of LED.

setting), the system is rebooted and the automatic address setting will be judged again.  
1) Connect 3 In/Out cables surely.  
2) Check line address/indoor address/group address of the unit one by one.  
3) The unit No. (line/indoor gout address) which have been set once keep the present status as a rule if the  
unit No. is not duplicated with one of another unit.

(Repetition)  
• In a group operation, if the indoor unit which was fed power after judgment of automatic address cannot  
receive regular communication from the master unit and regular communication on identical pipe within  
120 seconds after power was turned on, it reboots (system reset).  
→ The operation starts from judgment of automatic address (Gr construction check) again.  
(If the address of the master unit was determined in the previous time, the power fed to the master unit and  
reboot works, the master unit may change though the indoor unit line address is not changed.)

Group address : 0 = Single (Not group control)  
1 = Master unit in group control  
2 = Sub unit in group control  
Master unit (= 1) : The representative of multiple indoor units in group operation sends/receives signals to/from  
the remote controllers and sub indoor units.  
(* It has no relation with an indoor unit which communicates serially with the outdoor units.)  
The operation mode and setup temperature range are displayed on the remote controller LCD.  
(Except air direction adjustment of louver)  
Sub unit (= 2)  
: Indoor units other than master unit in group operation  
Basically, sub units do not send/receive signals to/from the remote controllers.  
(Except errors and response to demand of service data)  
Header unit (Representative unit) (Master Twin)  
: This unit communicates with the indoor unit (follower) which serial-communicates with the  
outdoor units and sends/receives signal (Command from compressor) to/from the outdoor  
units as the representative of the cycle control in the indoor units of the identical line address  
within the minimum unit which configures one of the refrigerating cycles of Twin.  
Follower unit (Subordinate unit) (Sub Twin)  
: Indoor units excluding the header unit in Twin  
This unit communicates with (Header) indoor unit in the identical line address and performs  
control synchronized with (Header) indoor unit.  
This unit does not perform the signal send/receive operation with the outdoor units. :  
No judgment for serial signal error.

• Header unit: The header unit receives the indoor unit data (thermo status) of the follower  
(Without identical line address & indoor/outdoor serial) and then finally controls the  
outdoor compressor matching with its own thermo status.  
The header unit sends this command information to the follower unit.  
• Follower unit: The follower unit receives the indoor unit data from the header  
(With identical line address & indoor/outdoor serial) and then performs the thermo  
operation synchronized with the header unit.  
The follower unit sends own thermo ON/OFF demand to the header unit.  
(Example)  
No. 1-1 header unit sends/receives signal to/from No. 1-2 and No. 1-3 follower units.

<Maintenance/Check list>  
Aiming in environmental preservation, it is strictly recommended to clean and maintain the indoor/outdoor units  
of the operating air conditioning system regularly to secure effective operation of the air conditioner.  
It is also recommended to maintain the units once a year regularly when operating the air conditioner for a long time.  
Check periodically signs of rust or scratches, etc. on coating of the outdoor units.  
Repair the defective position or apply the rust resisting paint if necessary.  
If an indoor unit operates for approx. 8 hours or more per day, usually it is necessary to clean the indoor/outdoor  
units once three months at least.  
These cleaning and maintenance should be carried out by a qualified dealer.  
Although the customer has to pay the charge for the maintenance, the life of the unit can be prolonged.  
Failure to clean the indoor/outdoor units regularly will cause shortage of capacity, freezing, water leakage or  
trouble on the compressor.

WARNINGS ON REFRIGERANT LEAKAGE  
Check of Concentration Limit  
Important  
The room in which the air conditioner is to be  
installed requires a design that in the event of  
refrigerant gas leaking out, its concentration will  
not exceed a set limit.  
NOTE 2 :  
The standards for minimum room volume are as follows.  
(1) No partition (shaded portion)  
The refrigerant R410A which is used in the air  
conditioner is safe, without the toxicity or combustibility  
of ammonia, and is not restricted by laws to be imposed  
which protect the ozone layer.  
However, since it contains more than air, it poses the  
risk of suffocation if its concentration should rise  
excessively. Suffocation from leakage of R410A is  
almost non-existent.  
With the recent increase in the number of high  
concentration buildings, however, the installation of  
multi air conditioner systems is on the increase because  
of the need for effective use of floor space, individual  
control, energy conservation by curtailing heat and  
carrying power etc.  
(2) When there is an effective opening with the  
adjacent room for ventilation of leaking refrigerant  
gas (opening without a door, or an opening 0.15%  
or larger than the respective floor spaces at the top  
or bottom of the door).  
Outdoor unit  
Most importantly, the multi air conditioner system is able  
to replenish a large amount of refrigerant compared with  
conventional individual air conditioners.  
Refrigerant piping  
Indoor unit  
If a single unit of the multi conditioner system is to be  
installed in a small room, select a suitable model and  
installation procedure so that if the refrigerant  
accidentally leaks out, its concentration does not reach  
the limit (and in the event of an emergency, measures  
can be made before injury can occur).  
In a room where the concentration may exceed the limit,  
create an opening with adjacent rooms, or install  
mechanical ventilation combined with a gas leak  
detection device.  
(3) If an indoor unit is installed in each partitioned room  
and the refrigerant piping is interconnected, the  
smallest room of course becomes the object. But  
when a mechanical ventilation is installed  
interlocked with a gas leakage detector in the  
smallest room where the density limit is exceeded,  
the volume of the next smallest room becomes the  
object.  
The concentration is as given below.

NOTE 1 :  
If there are 2 or more refrigerating systems in a single  
refrigerating device, the amounts of refrigerant should  
be as charged in each independent device.  
NOTE 3 :  
The minimum indoor floor area compared with the  
amount of refrigerant is roughly as follows:
