BS button (Pump down / Forced defrosting)
Pressing the BS button forcibly operates the air conditioner in the cooling mode.
1. To conduct a pump-down operation (sending refrigerant to outdoor unit), press the BS
button to forcibly operate the equipment in the cooling mode, then operate the unit for about
1 minute to stabilize the system. After stabilizing system, close the liquid pipe stop valve on
the outdoor unit, and after the pressure decreases and the low pressure sensor activates,
close the gas pipe stop valve.
2. Forced defrost
To activate the defrost operation during the heating operation, press the BS button. This will
activate the forced defrost operation (cooling operation).
When the defrost cancel conditions are met, the equipment automatically switches off the
defrost operation.
