Trail  Operation And Testing 

1. Trial operation and testing

•  Check that the inter-unit wire is correctly connected. 
•  Trial operation should be carried out in COOL operation. 

1-1  Measure the supply voltage and make sure that it is within the specified range. 

1-2  Select the lowest programmable temperature. 

1-3 Carry out the trial operation following the instructions in the operation manual to ensure that all functions and parts, 

such as the movement of the flaps, are working properly. 

• To protect the air conditioner,  restart operation is disabled  for 3 minutes after the system has been turned off.

1-4 After trial operation is complete, set the temperature to a normal level (26

°

C to 28

°

C in COOL  operation, 20

°

c to 24

°

in HEAT operation). 

•  When operating the air conditioner in COOL operation in winter, or HEAT operation in summer, set it to the trial operation mode using the following method. 

1)  Press NMODE" button and select the cooling or heating mode. 

2)  Press "ON/OFF" button to  turn on the system. 

3)  Press both of "TEMP" button and NMODE" button at the same time. 

4)  Press "TEMP· button, select Nr•, and press "MODE" button for confirmation. 

• Trial operation will stop automatically after about 30 minutes. To stop the operation press ·oN/OFF" button. 

• The air conditioner draws a small amount of power in its standby mode. If the system is not to be used for some time after installation, shut off the circuit breaker to 

eliminate unnecessary power consumption. 

• If the circuit breaker trips to shut  off the  power  to the air conditioner,  the system  will  restore the original operation mode when  the circuit  breaker is 

turned  on again. 

2. Items to Check

Test  Items 

Symptom 

Check 

Indoor and outdoor units  are  installed securely. 

Fall,  vibration,  noise 

No refrigerant gas leaks. 

Incomplete cooling function 

Refrigerant gas and  liquid pipes and indoor  drain hose 

Water  leakage 

extension are  thermally  insulated. 

Draining  line is  properly  installed. 

Water  leakage 

System is  properly  earthed. 

Electrical leakage 

Only specified wires are  used for all wiring,  and all 

No operation or  burn damage 

wires  are  connected correctly. 

Indoor or outdoor unit's air intake or exhaust has clear path of air.  Incomplete  cooling  function 

Stop valves are opened. 

Incomplete cooling function 

Indoor unit properly receives remote controller commands. 

No operation 

Pump Down Operation 

� WARNING---------------

• Make sure that air or any matter other than refrigerant (R32) does not get into the refrigeration cycle. 

• When performing a pump down, turn off the compressor before detaching the refrigerant pipes.  {If the refrigerant pipes are detached when 

the compressor is operating and the stop valves are open, air will be drawn in leading to abnormally high pressure in the 

refrigeration cycle. This may result in rupturing and bodily injury.) 

In order to protect the environment, be sure to pump down when relocating or disposing of the unit. 

1)  Remove the valve cap from the liquid stop valve and gas stop valve. 

2)  Begin forced cooling operation. 

3)  After 5 to  10 minutes, close the liquid stop valve with a hexagonal wrench. 

4)  After 2 to 3 minutes, close the gas stop valve and stop forced cooling operation. 

5)  Attach the valve cap once procedures are complete. 

Forced cooling operation 

■  Using the indoor unit ON/OFF switch 

Press and hold the indoor unit ON/OFF switch for at least 5 seconds. (The operation will start.) 

• Forced cooling operation will stop automatically after about 15 minutes. 

To stop the operation, press the indoor unit ON/OFF switch. 

Disclaimer: Appearance of indoor & outdoor unit may differ 

between different models.
