(4) Precautions for pumping-down operation
(When moving and remounting the indoor or outdoor units, etc.)
Turn on the power and enter pump-down operation using the following procedure.
This is the end of pumping-down operation. After pumping-down oper-
ation, the remote controller shows “U4” even when ON button on the remote controller is pressed, and it will
not operate. Turn off the main power supply switch and turn it on again in need of operation.
To all persons doing pipe work.
Be sure to open the shut-off valve after finishing pipe work. (Operating the unit with it closed will cause the
compressor to break.)
Procedure
Precautions
1
Start fan operation with the
remote controller.
Confirm that stop valves both on
the liquid and gas side are open.
Take care when the procedure 2
is done first because the indoor
unit fan may operate automati-
cally.
2
Push the pumping down but-
ton on the PC board of the out-
door unit.
Compressor and outdoor fan will
start operation automatically.
3
Once operation stops after about 3 or 5 minutes, close the shut-
off valves for the gas and liquid sides. (Refer to Fig. 11)
