Check in Normal Operation

After all installation works are completed, operate the unit normally and check the following:
Note:
Test Operation
Make sure the indoor units and outdoor unit are operating normally.
Operate each indoor unit separately and make sure the corresponding outdoor unit is also
operating properly.
Check if cold or hot air is coming out from the indoor unit.
Push the fan direction and fan strength buttons on the remote controller to check if they are
operating properly.
Heating is not possible if the outdoor temperature is 24°C or higher. Refer to the operation
manual.
If a knocking sound is heard in the liquid compression of the compressor, stop the unit
immediately and then energize the crankcase heater for a sufficient length of time before
restarting the operation.
Once stopped, the compressor will not restart in about 5 minutes, even if the ON/OFF button
on the remote controller is pushed.
When the system operation is stopped by the remote controller, the outdoor unit may
continue operation for a maximum of 5 minutes.
The outdoor fan may rotate at low speeds in the night-time low noise setting or the external
low noise level setting is made; but this is not a malfunction.
