Part II
1. Service warning
Part I General Warnings
1、The service person should wear safety belt if working more than 2.5m above the ground.
2、If working above ground level, measures should be adopted to prevent the outdoor unit or tools
from falling and causing injuries or damage.
3、Check the customers power supply before testing the unit.
4、The power supply should be switched OFF when disassembling the casing and electrical
components.
5、Take care to prevent a frost bite injury when charging with refrigerant.
6、Do not over pressurize the Freon cylinder. The over exposure, high temperature or dropping the
cylinder should be avoided, otherwise, it could cause an explosion.
7、If there is need to pressure test the system, Dry Nitrogen should be used.
Part II Warnings of repair operation
1、
The high capacity electrolytic capacitor is used in the electric control cabinet of the outdoor unit.
Even if the power plug is unplugged; this capacitor will retain a residual charge for a certain time. In
order to avoid electric shock, please do not touch the control board as soon as the power is switched
OFF. If it is necessary to change the control board of the outdoor unit, please switch OFF the power
supply first. After the light emitting diode of outdoor control board extinguishes or the power is
switched OFF for >30 sec’s, let the high capacity capacitor discharges fully. The replacement can
only be conducted after checking the high capacity capacitor has discharged fully with an electrical
meter.
2、
After making use of self-diagnosis of faults on the site, switch the snap switch to “demonstrate”,
re-electrify the air-conditioner so that the system can erase the stored fault information of former
self-diagnosis. Switch the snap switch to “ON” again, prepare for re-starting the air-conditioner.
Because the LS-LT1508V model air-conditioner has not been fitted with an E2PROM (storage
device of fault information), the fault information will be automatically erased after switching OFF
the power.
3、
For diagnosis of the system fault, first it is suggested to check whether the electrical wiring is
reliable and correct. After eliminating this cause, continue to seek other causes.

4.1. Defrosting
1. Entry condition:
Defrosting starts when meeting one of the following conditions
a. The temperature of outdoor heat exchanger remains consecutively lower than 3°c for more than 40 minutes, and the
temperature remains consecutively -6°c for more than 3 minutes
b. The temperature of outdoor heat exchanger remains consecutively lower than 3°c for more than 80 minutes, and the
temperature remains consecutively -4°c for more than 3 minutes
c. The temperature of outdoor heat exchanger remains consecutively lower than 3°c for more than 120 minutes, and the
temperature remains consecutively -3°c for more than 3 minutes
2. .Ending condition of defrosting
If one of following conditions is satisfied, end the defrosting and turn into heating mode:
a. The defrost time has reached to 10 minutes.
b. When the temperature of outdoor heat exchanger rises up to 15°C.

4.5.2 Indoor heat exchanger anti-overheated
When indoor exchanger temperature is higher than 50℃, the compressor frequency
will be lowered down to protect the heat exchanger. When indoor exchanger temperature lower down
to 46℃, the compressor frequency rise up, and when the indoor exchanger temperature lower to 44
℃ and keep for 5 minutes, and compressor frequency will rise to former value.
Whencondensertemperatureishigherthan54℃, thecompressorwillstop, andhenthecondenser
temperature lower to 44℃ and keep for 5 minutes, and compressor frequency will rise to former value
4.6 Emergency Operation
The set temperature is 24℃, and the fan speed is AUTO during emergency operation.
Press emergency switch within 5 s during stand-by mode, and the air conditioner starts emergency mode if
there is DU sound from indoor unit.
Press emergency switch during operation mode, and the air conditioner can be turned off.
Note: During emergency mode, the air conditioner will turn to the mode set by remote controller after
receiving signal from remote controller.
4.7 Sleeping operation
Cooling mode: Press sleep button, the fan speed lower down one class automatically ( HI-ME-LO-VL). The
set temperature rise one degree, and rise one degree again one hour later, then keep it.
Heating mode: Press sleep button, the fan speed lower down one class automatically (HI-ME-LO-VL). The set
temperature lower one degree, and lower one degree again one hour later, then keep it.
Note: During sleep mode, if change the set temperature, the actual set temperature is new set temperature
plus lowered or rised temperature.
4.8 Auto restart:
The air conditioner will restart with set mode automatically after power on again, and this can be canceled by
user, and to cancel this mode follow the following instructions:
1. Press ON/OFF button 6 times within 7 s, and the AUTO restart mode can be cancelled.

4.9 Refrigerant charge mode
Entry condition：
Press the emergency switch over 5 seconds, there will be three “DU” sound in the indoor unit, and start
the unit with the remote controller.
Actions：
1. On cooling mode, the indoor fan speed is low
the frequency is fixed on F6,
2. Cancel the mode：
Turn off the air conditioner with remote controller
5. Protection
5.1 Compressor protection
5.1.1 High pipe discharge temperature protection
When discharge pipe temperature is higher than T3, the compressor frequency will
be lowered, when discharge pipe temperature lower to T1, the frequency will rise, and the
frequency will be limited one class than former one. When the discharge pipe temperature
lower to T2 and keep for 10 minutes, the frequency will return to former one.
When discharge pipe temperature is higher than T4, the compressor stop and the
outdoor motor stop 15s later. When discharge pipe temperature lower to T1 and the unit
restart after 3 minutes.

5.1.2 Sensor protection
There is thermal sensor on compressor, and the compressor will stop when the temperature is too
high, and the outdoor motor will stop 15s later. When the temperature return normal value, the
compressor will restart 3 minutes later.
5.1.3 Compressor relay start protection
The compressor will restart 3 minutes after stop.
5.2 Current protection
When outdoor current is higher than I1, the compressor frequency will be limited and prohibited to rise. When the
current is higher than I2, and the compressor frequency will lower until the current is lower than I1.
When outdoor current is lower than I3, the compressor will stop.
The detailed current value see below table:
