Pumping down refrigerant

Pump-down is an operation intended to collect all the system refrigerant in the outdoor unit. This operation must be carried out before disconnecting the refrigerant tubing in order to avoid refrigerant loss to the atmosphere.

1.Shut off the liquid valve with the Allen wrench.

2.Turn on the air conditioner in cooling with fan operating at high velocity. (Compressor will immediately start, provided 3 minutes have elapsed since the last stop.)

3.After 2 minutes of operation, shut the suction valve with the same wrench.

4.Turn off the air conditioner and switch mains supply off.

5.Disconnect tubing. After disconnection, protect valves and tubing ends from dust.

CAUTION

•Compressor damage may occur if the compressor is run at a negative suction pressure.
