PUMP DOWN (Refrigerant collecting operation)

Perform the following procedures to collect the refrigerant when
moving the indoor unit or the outdoor unit.

(1) Press the push-button switch (SW2) on the circuit board once.
The LED on the circuit board starts flashing (one second ON/
one second OFF). This indicates the start of PUMP DOWN
operation.
When the switch is pressed while the compressor is in opera­tion, PUMP DOWN operation starts automatically.
When the switch is pressed while the compressor is in stop,
the compressor starts to operate automatically, and then move
on to PUMP DOWN operation.

(2) PUMP DOWN operation continues for about 1 minute. When
PUMP DOWN operation is completed, the compressor stops
automatically. Then close the 2-way valve and 3-way valve
within 1 minute.

(3) Turn the power off.
