Pump down Pump down is preferably carried out with the indoor unit set to “fan only” in order to avoid compressor

restart with closed stop valves after finishing the previous pump down operation (close stop valves,

turn OFF the power supply).

If accidentally, the power was switched back ON, the unit will automatically restart with closed stop

valves, which may result in a possible compressor breakdown.
