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.

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

*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.
