PUMP DOWN (before disconnecing t the refrigerant connections for unit repair,
removal or disposal)
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 pipe in order to avoid
refrigerant loss to the atmosphere.
- Shut off all the liquid valve with the Allen wrench.
- Turn the system on in cooling with fan operating at high velocity.
(Compressor will immediately start, provided 3 minutes have elapsed since the last stop).
- After 2 minutes of operation, shut down the suction valves with the same wrench.
- Turn the system off and switch mains supply off.
- Disconnect pipes. After disconnection, protect valves and tubing ends from dust.
- Compressor damage may occur if run at a negative suction pressure.
