1. Make a TEST RUN in accordance with the installation instruction sheet for the indoor unit.
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.
2
The pump down operation (cooling operation) begins after three minutes. Close the three-way valve
(liquid) after operation starts.
3
After 2 - 3 minutes, operation stops. Close the threeway valve (gas) within one minute after operations
stops.
4
The LED will go out three minutes after it stops. Disconnect the power supply after confirming that the
LED has gone out.
2. OUTDOOR UNIT LEDS
When a malfunction occurs in the outdoor unit, the LED on
the circuit board lights to indicate the error. Refer to the following table for the description of each error according to the

*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 after 2 - 3 minutes 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.
