When a malfunction occurs in the outdoor unit, the LED onthe circuit board lights to indicate the error. Refer to the fol-lowing table for the description of each error according to theLED.
SPECIAL INSTALLATIONSETTINGPUMP DOWN (Refrigerant collecting operation)
1. When the product is stopped:
Perform the following procedures to collect the refrigerantwhen moving the indoor unit or the outdoor unit.

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-gins right away. After oparation starts, close thethree-way valve (liquid).
After 2 - 3 minutes, operation stops. Close the three-way valve (gas) within one minute after operationsstops.
The LED will go out three minutes after it stops.Dis-connect the power supply after confirming that theLED has gone out.
*When the pump down operation is repeated, temporarily disconnectthe power supply after opening the closed valves (both liquid and gas).Reconnect the power supply after 2 - 3 minutes and perform the pumpdown operation.
*When the start of the operation after pump down operation has beencompleted, temporarily disconnect the power supply after opening theclosed valves (both liquid and gas).Reconnect the power supply after 2-3 minutes and be sure to performa test operation for cooling.
