When relocating or disposing of the air conditioner, pump down the system following
the procedure below so that no refrigerant is released into the atmosphere.
1
Turn off the power supply (circuit breaker).
2
Connect the gauge manifold valve to the service port of the stop valve on the gas
pipe side of the outdoor unit.
3
Fully close the stop valve on the liquid pipe side of the outdoor unit.
4
Supply power (circuit breaker).
5
Perform the refrigerant collecting operation (cooling test run).
•
For the PAR-31MAA, select “Service”
→
“TestRun” from the main menu to start
the test run, and then select the cooling mode.
•
For details or for other information about starting the test run when using re-
mote controllers, refer to the installation manual for the indoor unit or the re-
mote controller.
6
Fully close the stop valve on the gas pipe side of the outdoor unit when the pres-
sure gauge shows 0.05 to 0 MPa [Gauge] (approx. 0.5 to 0 kgf/cm
2
) and quickly
stop the air conditioner.
•
Push the “ON/OFF” button on the remote controller to stop the air conditioner.
*
Note that when the extension piping is very long with a large refrigerant
amount, it may not be possible to perform a pump-down operation. In this case,
use refrigerant recovery equipment to collect all of the refrigerant in the system.
*
If the extension piping length for the SUZ-SA100VA is 20 m or longer, it will
not be possible to perform a pump-down operation because there is a large
amount of refrigerant. In this case, collect the refrigerant in the system.
7
Turn off the power supply (circuit breaker), remove the gauge manifold valve, and
then disconnect the refrigerant pipes.
Warning:
When pumping down the refrigerant, stop the compressor before disconnect-
ing the refrigerant pipes.
• If the refrigerant pipes are disconnected while the compressor is operating
and the stop valve (ball valve) is open, the pressure in the refrigeration cycle
could become extremely high if air is drawn in, causing the pipes to burst,
personal injury, etc.
