SPECIAL INSTALLATION SETTING
PUMP DOWN (Refrigerant collecting operation)
1. When the product is stopped:
Perform the following procedures to collect the refrigerant
when moving the indoor unit or outdoor unit
1
2
3
4
Press the PUMP DOWN switch on the outdoor unit.
(The LED on the outdoor unit circuit board starts flashing.)
(1 sec. on / 1 sec. off repeated)
The pump down operation (cooling operation) begins
right away. After oparation starts, close the three-way
valve (liquid).
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.
Disconnect 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 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.
2. When the product is operating:
1

4
Press the PUMP DOWN switch on the outdoor unit.
The LED on the outdoor unit circuit board starts flashing
( 1 sec. on / 1 sec. off repeated), and operation stops.
At this point, recovery has not been completed, so do not
close the three-way valves. (liquid and gas)
The pump down operation (cooling operation) be-
gins after three minutes. Close the three-way valve
(liquid) after operation starts.
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.
