Important
When Installing
Please Read Before Starting
.............................................................................................
…In a Room
This air conditioning system meets strict safety and operating
standards. As the installer or service person, it is an important
part of your job to install or service the system so it operates
safely and efficiently.
Properly insulate any tubing run inside a room to prevent
“sweating” that can cause dripping and water damage to walls
and floors.
…In Moist or Uneven Locations
For safe installation and trouble-free operation, you must :
G Carefully read this instruction booklet before beginning.
G Follow each installation or repair step exactly as shown.
G Observe all local, state, and national electrical codes.
Use a raised concrete pad or concrete blocks to provide a
solid, level foundation for the outdoor unit. This prevents water
damage and abnormal vibration.
…In an area with High Winds
Securely anchor the outdoor unit down with bolts and a metal
frame. Provide a suitable air baffle.
G Pay close attention to all warning and caution notices
given in this manual.
…In a Snowy Area (for Heat Pump-type Sys-tems)
Install the outdoor unit on a raised platform that is higher than
drifting snow. Provide snow vents.
This symbol refers to a hazard or
unsafe practice which can result
in severe personal injury or death.
When Connecting Refrigerant Tubing
.............................................................................................
This symbol refers to a hazard or
unsafe practice which can result
in personal injury or product or
property damage.
G
Ventilate the room well, in the event that refrigerant gas
leaks during the installation. Be careful not to allow contact
of the refrigerant gas with a flame as this will cause the
generation of poisonous gas.
CAUTION
G
Keep all tubing runs as short as possible.
If Necessary, Get Help
These instructions are all you need for most installation sites
and maintenance conditions. If you require help for a special
problem, contact our sales/service outlet or your certified
dealer for additional instructions.
G
Use the flare method for connecting tubing.
G
Apply refrigerant lubricant to the matching surfaces of the
flare and union tubes before connecting them, then tighten
the nut with a torque wrench for a leak-free connection.
In Case of Improper Installation
G
Check carefully for leaks before starting the test run.
The manufacturer shall in no way be responsible for improper
installation or maintenance service, including failure to follow
the instructions in this document.
NOTE
Depending on the system type, liquid and gas lines may be
either narrow or wide. Therefore, to avoid confusion the
refrigerant tubing for your particular model is specified as either
“narrow” or “wide” rather than as “liquid” or “gas”.
SPECIAL PRECAUTIONS
When Wiring
.............................................................................................
ELECTRICAL SHOCK CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH. ONLY A
QUALIFIED, EXPERIENCED ELECTRICIAN
SHOULD ATTEMPT TO WIRE THIS SYSTEM.
When Servicing
..............................................................................................
G
Turn the power OFF at the main power box (mains) before
opening the unit to check or repair electrical parts and
G
wiring.
Do not supply power to the unit until all wiring and tubing are
completed or reconnected and checked.
G
Keep your fingers and clothing away from any moving parts.
G
Highly dangerous electrical voltages are used in this system.
G
Clean up the site when installation is finished. Check that no
Carefully refer to the wiring diagram and these instructions
when wiring. Improper connections and inadequate
grounding can cause accidentaly injury or death.
metal scraps or bits of wiring have been left inside the unit.
G
Ground the unit following local electrical codes.
CAUTION
G
Connect all wiring tightly. Loose wiring may cause overheat-
ing at connection points and a possible fire hazard.
G
Ventilate any enclosed areas when installing or testing the
refrigeration system. Contact of refrigerant gas with fire or
heat can produce poisonous gas.
When Transporting
...............................................................................................
G
Be careful when picking up and moving the indoor and outdoor
units. Get a partner to help, and bend your knees when lifting
to reduce strain on your back. Sharp edges or thin aluminum
fins on the air conditioner can cut your fingers.
Confirm after installation that no refrigerant gas is leaking. If
the gas comes in contact with a burning stove, gas water
heater, electric room heater or other heat source, it can
cause the generation of poisonous gas.

REMARKS: 1. Value obtained in the actual place where the unit is installed may be slightly higher than the values shown
in this graph because of the conditions of operation, the structure of the building, the background noise and
other factors.
2. The test results were obtained from an nechoic room.
NOTE
To evaluate “Noise level” the maximum number of the measured OCTAVE BAND SOUND PRESSURE LEVEL is used.
Read the number on each BAND CENTER FREQUENCIES (horizontal axis) ranging from 63 Hz to 8000 Hz and select the

1-9 Increasing the Fan Speed
Electrical component box
If external static pressure is too great (due to long extension
of ducts, for example), the air flow volume may drop too low
at each air outlet. This problem may be solved by increasing
the fan speed using the following procedure:
Jumper cable
Fan
motor
Jumper cable
Fan motor socket
(At shipment)
(1) Remove 4 screws on the electrical component box and
remove the cover plate.
(Jumper cable installed)

(2) Disconnect the fan motor sockets in the box.
(3) Take out the jumper cable (sockets at both ends) clamped
in the box.
(4) Securely connect the jumper cable sockets
between the disconnected fan motor sockets in step 2.
(5) Place the cable neatly in the box and reinstall the cover
plate.

How to read the diagram
The vertical axis is the external static pressure (Pa) while the horizontal axis represents the AIR FLOW (CFM).
The characteristic curves for “HT”, “H”, “M” and “L” fan speed control are shown.
The nameplate values are shown based on the “H” air flow. For the 26 type, the air flow is 636 CFM, while the
external static pressure is 49 Pa at “H” position. If external static pressure is too great (due to long extension of
duct, for example), the air flow volume may drop too low at each air outlet.
This problem may be solved by increasing the fan speed as explained above.

Installing the Unit in Heavy Snow Areas
In locations with strong wind, snow-proof ducting should
be fitted and direct exposure to the wind should be
avoided as much as possible.
Countermeasures against snow and wind
In regions with snow and strong wind, the following
problems may occur when the outdoor unit is not
provided with a platform and snow-proof ducting:
Fig. 1-5
a) The outdoor fan may not run and damage to the unit
may occur.
In regions with significant snowfall, the outdoor unit
should be provided with a platform and snow-proof duct.
b) There may be no air flow.
c) The tubing may freeze and burst.
d) The condenser pressure may drop because of strong
wind, and the indoor unit may freeze.
1
Precautions for Installation in Heavy Snow Areas
1) The platform should be higher than the max. snow
depth. (Fig. 1-6)
2) The 2 anchoring feet of the outdoor unit should be
used for the platform, and the platform should be
installed beneath the air intake side of outdoor unit.
3) The platform foundation must be firm and the unit
must be secured with anchor bolts.
Without snow-
proof ducting

General Precautions on Wiring
1) Before wiring, confirm the rated voltage of the unit as
shown on its nameplate, then carry out the wiring
closely following the wiring diagram.
7) To prevent possible hazards from insulation failure,
the unit must be grounded.
2) Provide a power outlet to be used exclusively for
each unit, and a power supply disconnect and circuit
breaker for overcurrent protection should be provided
in the exclusive line.
8) To prevent malfunction of the air conditioner caused
by electrical noise, care must be taken when wiring
as follows:
The remote control wiring and the inter-unit
control wiring should be wired apart from the inter-
unit power wiring.
3) To prevent possible hazards from insulation failure,
the unit must be grounded.
4) Each wiring connection must be done in accordance
with the wiring system diagram.
Use shielded wires for inter-unit control wiring
between units and ground the shield on both
sides.
Wrong wiring may cause the unit to misoperate or
become damaged.
9) If the power supply cord of this appliance is dam-
aged, it must be replaced by a repair shop appointed
by the manufacturer, because specialpurpose tools
are required.
5) Do not allow wiring to touch the refrigerant tubing,
compressor, or any moving parts of the fan.
6) Unauthorized changes in the internal wiring can be
very dangerous.The manufacturer will accept no
responsibility for any damage or misoperation that
occurs as a result of such unauthorized changes.
10)All wiring used must be Class 1.

2-2 Cold Draft Prevention (Heating Cycle)
The cold draft prevention function controls indoor fan speed so a strong draft of cold air will
not blow out before the indoor heat exchange coils have warmed up.
❑ STANDBY shows on the remote controller when the indoor fan speed is LL (very low)
or OFF. This condition occurs in the following 3 cases:
• During Thermo OFF (refer to 2-1 B. Room Temperature Control, Heating)
• During the defrosting operation (refer to 2-10 Defrosting Control, Heating)
• Until either the coil temperature E2 reaches 81°F or when a maximum of 6 minutes
has past.
❑ The indoor fan motor operates in L instead of LL for 3 seconds as it starts to give the

2. Processes and functions
(2) If the outdoor heat exchanger temperature (C1) is
75°F or higher continuously for 5 minutes, fan
operation may stop (same conditions as when the
thermostat is OFF). In this case, the fan will restart
after 3 minutes.
(3) This control is not performed during the 3 minutes
after start, for 1 minute after defrost ends, and
while defrost is in progress.
2-4 Control Functions
Electronic control valve control
Opening of the electronic control valve is controlled so
that the appropriate operating conditions are maintained,
based on the signal from each sensor (discharge
temperature [TD], intake temperature [TS], outdoor heat
exchanger temperature [C1], and indoor heat exchanger
temperature [E1, E2]).
Coil heating control
Discharge temperature release control
(1) This control lowers the operating frequency of the
compressor when electronic control valve control is
unable to maintain the appropriate operating
conditions because the discharge temperature fails
to decline or because there is a sudden increase in
the discharge temperature.
(2) If the discharge temperature exceeds 232°F, the
compressor is stopped and then restarted. (Error
count = 1)
(3) The error count is cleared when operation has
continued for 10 minutes after the compressor was
restarted.
(4) If (2) repeats 4 times without the error count being
cleared (error count = 4), alarm "P03" occurs.
(1) This control applies current to the coil of the
stopped compressor to heat the compressor in
place of the crank case heater.
(2) When the discharge temperature (TD) is less than
77°F, the current application judgment is made
based on the outdoor air temperature (TO).
• Current application starts when the outdoor air
temperature drops to 59°F or below.
• Current application stops when the outdoor air
temperature rises above 64°F.
Control for prevention of short intermittent operation
In order to protect the compressor, this control does not
allow the compressor to be stopped for 10 minutes after
operation starts, even if the thermostat OFF signal is
received from the indoor unit.
Control for prevention of high cooling loads
This control reduces abnormal high-pressure increases
during cooling operation.
2
Current release control
The compressor operating frequency is controlled so
that the current that is input to the inverter compressor
does not exceed the designated value (control value).
(1) If MAX (C1, C2) (C1 & C2: outdoor heat exchanger
temperature) is less than 124°F, the compressor
performs normal operation.
(2) If MAX (C1, C2) is 124°F or higher and less than
142°F, the revolution of the compressor is
controlled to prevent the high pressure being
increased.
(3) If MAX (C1, C2) is 142°F or higher, the compressor
stops once. The compressor restarts three times,
and if the temperature dose not decrease to less
than 142°F, the alert "P20" is displayed.
Outdoor unit fan control
1. Cooling fan control
(1) The outdoor unit fan minimum speed and maximum
speed are determined according to the outdoor air
temperature and the operating frequency.The
speed is controlled in stages between the minimum
speed and maximum speed, based on the outdoor
heat exchanger temperature (C2) at that time.
(2) For 60 seconds after start, the outdoor unit fan
operates at maximum speed, as determined by the
outdoor air temperature and operating frequency at
that time. Subsequently, the fan operates at low
speed until the outdoor heat exchanger temperature
(C2) rises.
142
124
(3) If the discharge temperature (TD) sensor is
abnormal or has become disconnected, the fan will
not operate and a protective device is activated.
2. Heating fan control
(1) The outdoor unit fan minimum speed and maximum
speed are determined according to the outdoor air
temperature and operating frequency.The speed is
controlled in stages between the minimum speed
and maximum speed, based on the outdoor heat
exchanger temperature (C1) at that time.
SM831148
II-6
2. Processes and functions
Heating high-load control
Overcurrent protection control
The below control is performed during heating operation,
based on the indoor heat exchanger temperature MAX
(E1,E2).
(1) If the overcurrent protection circuit detects
abnormal current, the compressor is stopped. (Error
count = 1.) The compressor then restarts after 3
minutes.
(2) If compressor start/stop is repeated 4 times (error
count = 4), alarm "P26", "P29" or "H01" (count = 2
in this case only) occurs. Operation stops and does
not restart.
(1) If the temperature is in the "M" area (operating
frequency reduction and thermostat OFF area), the
compressor operating frequency is reduced.
The compressor operating frequency is reduced
every 30 seconds as long as the temperature
remains within this area.
(2) If the temperature is continuously in the "M" area,
the thermostat turns OFF.
(3) If the temperature is in the "N" area, operating
Current release value shift control
(1) This control is intended to improve compressor
reliability by preventing continuous high-frequency
operation under overload conditions when the
outdoor air temperature is high, and by preventing
intermittent operation through "control for
prevention of high cooling loads".
(2) The control value for "current release control" is
corrected according to the outdoor air temperature
(TO).
frequency increases are prohibited.
(4) If the temperature is in the "L" area, the operating
frequency is raised to the original frequency (the
frequency prior to frequency reduction) by 6 Hz
every 60 seconds.
Depending on the temperature, the control value is
lowered to 50 – 90% for cooling operation, and to
60 – 98% for heating operation.
(30, 36, 48 types)
2
Freeze prevention (low-temperature release) control
The below control is performed during cooling operation
(including dehumidifying operation), using whichever of
the indoor heat exchanger temperatures (E1 or E2) is
lower. (See the figure below.)
(1) If a temperature in the "J" area (operating
frequency reduction and thermostat OFF area) is
detected for 6 minutes, the compressor operating
frequency is reduced.The compressor operating
frequency is reduced every 30 seconds as long as
the temperature remains within this area.
(2) If the temperature is in the "K" area (operating
frequency increase-prohibit area), the compressor
operating frequency is maintained.
(3) If the temperature is in the "H" area (operating
frequency control area), and the outdoor air
temperature is less than 90°F, the compressor
maximum operating frequency is limited according
to the indoor unit fan speed.
(4) If the temperature is in the "I" area (normal
operating area), the compressors operate normally.
(5) If the temperature is continuously in the "J" area
and the compressor operating frequency reaches 0,
then temperature A (temperature for changing from
"J" area to "H" area) is raised from 41°F to 46°F,
and operation continues with the thermostat OFF
until the temperature reaches the "H" area.
* When the compressor turns ON and the E2
temperature rises, the temperature at which the
"M" area is first entered is 124°F (30, 36, 42
types) or higher than 129°F (26 type).
If the E1, E2 temperature subsequently falls to
the "L" area, the temperature for entering the "M"
area is raised to 126°F (30, 36, 42 types) or 133°F
(26 type).
However if the E1, E2 temperature falls to the "L"
area and falls below 86°F, then the temperature for
entering the "M" area is changed back to 124°F
(30, 36, 42 types) or 129°F (26 type).

2. Processes and functions
2-6 Outdoor Unit Control PCB (CR-CH4272R)
(1) Explanation of Functions
S001
Push-button switch (black): Automatic address setting switch
• If the system address switch (S002: set to 0 at time of shipment) setting is other than
"0" (central control), press this switch once to automatically set the addresses at all
indoor units which are in the same system, and are connected to that outdoor unit.
During automatic address setting, the 2 LEDs (red) on the outdoor unit control PCB
blink alternately.
(Pressing this switch again stops automatic address setting.)
• If automatic address setting is currently in progress at another system that is subject
to central control, only LED 1 on the outdoor unit control PCB blinks to indicate that
automatic address setting is in progress at another unit. If automatic address setting is
in progress at another unit, automatic address setting cannot be started at this unit,
even if S001 is pressed.
Rotary switch (10 positions, black): System address setting switch
• This switch is set to 0 (1 system control) at the time of shipment. However the address
for each system must be set when multiple systems are controlled or when central
control is used. (Figure 1)
S002
• If the system address is set to 0, automatic address setting is started when the power is
turned ON. Therefore it is not necessary to use switch SW01 and perform automatic
address setting in the case of single or simultaneous-operation multi control of a single
system.
• When using central control for multiple systems, a maximum of 30 systems (maximum
64 units) can be connected. In the case of group control or central control, set the sys-
tem address to a setting other than 0 (1 or above).
• If the number of systems is greater than 9, this switch can be used in combination with
DIP switch S003 to set up to 30 systems. The setting can be made as high as 39,
however all settings above 30 are handled as 30 for control. (For details, refer to Table 1.)
• If system addresses are duplicated (the same address exists more than once), LED 1 on
the outdoor unit control PCB lights up, and alarm "L04" is displayed on the remote con-
troller.
2
DIP switch (2P, blue): System address 10s-digit and 20s-digit place setting switch
• When setting 10 systems or more, set this switch in combination with S002.
• For 10 – 19 systems, set 1P (10s-digit place) to ON.
• For 20 – 29 systems, set 2P (20s-digit place) to ON, and set 1P (10s-digit place) to OFF.
• For 30 systems, set both 1P (10s-digit place) and 2P (20s-digit place) to ON. (For details,
refer to Table 1.)
S003
S005
Refrigerant recovery switch (red button switch)
• Press this switch to perform refrigerant recovery control using cooling operation. The
indoor unit fan will operate at HIGH and 55 Hz for a maximum of 10 minutes. When
refrigerant recovery is completed, close the valves and press this switch to stop the
operation.

2. Processes and functions
Terminal plug
(CN015)
3P plug (black): Terminal plug for the communications line
• At the time of shipment from the factory, the short-circuiting socket (2P, black) is
installed between pins 1 and 2 on the terminal plug (terminal = yes).
• When central control is used for multiple systems, leave the short-circuiting socket in
place only on the outdoor unit with a system address of 1. At all other outdoor units
(other than unit No. 1), move the short-circuiting socket to between 2 and 3 (terminal =
no). If multiple short-circuiting sockets remain in place during central control, a com-
munications failure will occur.
• In the case of a single system only (system address = 0), do not remove the short-
circuiting socket. (Alarm "E04" will occur.)
Quiet mode
(CN028)
2P plug (white): Enables operation in quiet mode.
• The outdoor unit fan and compressor frequencies are subject to limits during operation.
• Low-noise operation is enabled when the relay is turned ON.

• Lead wire with 2P plug (special-order part: WIRE K/ 623-161-2098)
• Relay, field supply, contact input specifications: DC 5 V, 0.5 mA (Recommended relay:
Fuji Electric HH62SW, compatible with micro contacts)
• Use a commercially available timer (such as the Omron H5 daily time switch).

5. Outdoor unit maintenance remote control
5-1. Overview
What is the outdoor unit maintenance remote controller?
Beginning with the DC-INV series of outdoor units, nonvolatile memory (EEPROM) is
used in the outdoor unit PCB. In this way, the setting switches that were located on
earlier PCBs have been converted to EEPROM data.This remote controller is an
outdoor unit maintenance tool that is used to make and change the EEPROM set-
tings.
This remote controller can be used for checking the outdoor unit EEPROM settings
and contents, and also can be used to monitor the outdoor unit alarm history and
indoor/outdoor unit temperatures, and to check the status of the indoor unit connec-
tions (No. of units, operating status, etc.).
Note: Because this tool does not function as a remote controller, it is used only
during test runs and servicing.

6-6. Precautions
RCS-TM80BG
Request that the customer be present when the test run is performed. At this time, explain the operation manual
and have the customer perform the actual steps.
Be sure to pass the manuals and warranty certificate to the customer.
Check that the AC 230 / 208 V power is not connected to the inter-unit control wiring connector terminal.
*
If AC 230 / 208 V is accidentally applied, the indoor or outdoor unit control PCB fuse (0.5A for both indoor
and outdoor units) will blow in order to protect the PCB. Correct the wiring connections, then disconnect the
2P connectors (indoor: blue, OC) (outdoor: blue, OC) that are connected to the PCB, and replace them with
2P connectors (indoor: brown, EMG) (outdoor: brown, EMG). (Refer to the figure below.) If operation is still not
possible after changing the brown connectors, try cutting the varistor (VA002) (both indoor and outdoor).
(Be sure to turn the power OFF before performing this work.)

Indicating (marking) the indoor and outdoor unit combination number
Indicate (mark) the number after automatic address setting is completed.
(1) So that the combination of each indoor unit can be easily checked when multiple units are installed, ensure that
the indoor and outdoor unit numbers correspond to the system address number on the outdoor unit control PCB,
and use a magic marker or similar means which cannot be easily erased to indicate the numbers in an easily
visible location on the indoor units (near the indoor unit nameplates).
Example: (Outdoor) 1 - (Indoor) 1-1...(Outdoor) 2 - (Indoor) 2-2...
(2) These numbers will be needed for maintenance. Be sure to indicate them.
