•
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 SW4 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 SW4-2.
2
Turn on SW4-1 to start test run with the operation mode set by SW4-2.
3
Turn off SW4-1 to finish the test run.
•
There may be a faint knocking sound around the machine room after power is supplied.
However, this is not a problem with product because the linear expansion pipe is just mov-
ing to adjust opening pulse.
•
There may be a knocking sound around the machine room for several seconds after com-
pressor starts operating. However, 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.)
