1. When the product is stopped:
When a malfunction occurs in the outdoor unit, the LED on
the circuit board lights to indicate the error. Refer to the fol-
lowing table for the description of each error according to the
LED.
Perform the following procedures to collect the refrigerant
when moving the indoor unit or the outdoor unit.
*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 after2-3minutesandperform 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.

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-
gins right away. After oparation starts, close the
three-way valve (liquid).
The pump down operation (cooling operation) be-
gins after three minutes. Close the three-way valve
(liquid) after operation starts.
After2-3minutes, operation stops. Close the three-
way valve (gas) within one minute after operations
stops.
After 2 - 3 minutes, operation stops. Close the three-
way valve (gas) within one minute after operations
stops.
The LED will go out three minutes after it stops.Dis-
connect the power supply after confirming that the
LED has gone out.
