5-3. PUMPING DOWN
When relocating or disposing of the air conditioner, pump down the system following the
procedure below so that no refrigerant is released into the atmosphere.
1) Connect the gauge manifold valve to the service port of the stop valve on the gas pipe
side of the outdoor unit.
2) Fully close the stop valve on the liquid pipe side of the outdoor unit.
3) Close the stop valve on the gas pipe side of the outdoor unit almost completely so that it
can be easily closed fully when the pressure gauge shows 0 MPa [Gauge] (0 kgf/cm
2
).
4) Start the emergency COOL operation.
To start the emergency operation in COOL mode, disconnect the power supply plug and/
or turn off the breaker. After 15 seconds, connect the power supply plug and/or turn on
the breaker, and then press the E.O. SW once. (The emergency COOL operation can be
performed continuously for up to 30 minutes.)
5) Fully close the stop valve on the gas pipe side of the outdoor unit when the pressure gauge
shows 0.05 to 0 MPa [Gauge] (approx. 0.5 to 0 kgf/cm
2
).
6) Stop the emergency COOL operation.
Press the E.O. SW several times until all LED lamps turn off. Refer to operating instruc-
tions for details.
