Pump down

(Pump down is adopted in the case of

unit removal for re-installation, aban-

donment, repair etc.)

Pump down is to collect the refrigerant into

the outdoor unit by control of the 2 and 3-

way valves and the compressor.

1. Stop the Heatpump operation.

2. Remove both valve shaft caps of the 2

and 3-way valves.

3. Run the Heatpump at cooling test run

mode (Refer to TEST RUN). If pump

down is performed at normal cooling op-

eration, the protection system may en-

gage and stop the operation.
