SPECIAL INSTALLATION
SETTING

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 immediately.

(3) Turn the power off.
