2. When the product is operating:
1
Press the PUMP DOWN switch on the outdoor unit. The LED on the outdoor unit circuit board lights, and operation stops. At this point, recovery has not been completed, so do not close the two- and three-way valves.
The pump down operation (cooling operation) be-
2
gins after three minutes. Close the three-way valve (liquid) after operation starts.
After2-3minutes, operation stops. Close the three-
3
way valve (gas) within one minute after operations stops.
The LED will go out three minutes after it stops. Dis-
4
connect the power supply after confirming that the LED has gone out.
*When the pump down operation is repeated, temporarily disconnect the power supply after opening the closed valves (both liquid and gas). Reconnect the power supply after2-3minutes and perform the pump down operation.
*When the start of the operation after pump down operation has been completed, temporarily disconnect the power supply after opening the closed valves (both liquid and gas). Reconnect the power supply after 2-3 minutes and be sure to perform a test operation for cooling.

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. When the product is stopped:
1
Press the PUMP DOWN switch on the outdoor unit. (The LED on the outdoor unit circuit board lights.)
The pump down operation (cooling operation) be-
2
gins right away. After oparation starts, close the three-way valve (liquid).
3
After2-3minutes, operation stops. Close the three­way valve (gas) within one minute after operations stops.
