Trial Operation and Testing

• Before starting the test run, measure the voltage at the primary side of the safety breaker. 
• Check that all liquid and gas stop valves are fully open.
• Check that piping and wiring all match. 

1.

Trial operation and testing

1) To test cooling, set for the lowest temperature. To test heating, set for the highest temperature. (Depending on the room 

temperature, only heating or cooling (but not both) may be possible.)

2) After the unit is stopped, it will not start again (heating or cooling) for approximately 3 minutes.
3) During the test run, first check the operation of each unit individually. Then also check the simultaneous operation of 

all indoor units.
Check both heating and cooling operation.

4) After running the unit for approximately 20 minutes, measure the temperatures at the indoor unit inlet and outlet. If the 

measurements are above the values shown in the table below, then they are normal.

(When running in one room)

5) During cooling operation, frost may form on the gas stop valve or other parts. This is normal.
6) Operate the indoor units in accordance with the included operation manual. Check that they operate normally.

Items to check 

ATTENTION

• Have the customer actually operate the unit while looking at the manual included with the indoor unit. Instruct the customer 

how to operate the unit correctly (particularly cleaning of the air filters, operation procedures, and temperature adjustment).

• Even when the air conditioner is not operating, it consumes some electric power. If the customer is not going to use the unit 

soon after it is installed, turn off the breaker to avoid wasting electricity.

• If additional refrigerant has been charged because of long piping, list the amount added on the nameplate on the reverse side 

of the stop valve cover.
