Start and finish of test run [For outdoor controller board]

 

• 

Operation from the indoor unit

Execute the test run using the installation manual for the indoor unit.

 

• 

Operation from the outdoor unit

By using the DIP switch SW on the control board of outdoor unit, test run can be started and finished, and its operation 
mode (cooling/heating) can be set up.

1

Set the operation mode (cooling/heating) using SW-.

2

Turn on SW-1 to start test run with the operation mode set by SW-.

3

Turn off SW-1 to finish the test run.

 

• 

There may be a faint knocking sound around the machine room after power is supplied, 

but this is no problem with product because the linear expansion pipe is just moving to 
adjust opening pulse.

 

• 

There may be a knocking sound around the machine room for several seconds after com-

pressor starts operating. But this is not a problem with product because the check valve 
itself generates the sound because pressure difference is small in the refrigerant circuit.

Note:
The operation mode cannot be changed by SW4-2 during test run. (To change test run mode, stop the unit by SW4-1, 
change the operation mode and restart the test run by SW4-1.)
