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 2a•c in COOL operation, 2o•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 "MODE" 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 "MODE" button at the same time. 
4)  Press "TEMP" button, select 

"7', 

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

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.  {II 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. 

Hexagonal 
wrench 

5)  Attach the valve cap once procedures are complete.

■  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.
