9. Pumping down
9 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
stop the outdoor unit.
• Push the "ON/OFF" button on the remote controller to stop the outdoor unit.
* 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.
0 Set back the main controller setting changed at the procedure 8 above.
1 Push the "ON/OFF" button for about 3 seconds on the main controller of the in-
door unit to stop the unit.
2 Set back the main controller settings changed at any other procedure except 8.
* How to set back "Running information": Set Reference address to 350.
3 Turn OFF all the supply circuit and set back the DIP switch settings on the indoor
circuit board as it were.

When the refrigeration circuit has a leak, DO NOT execute pump down with
the compressor.
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.
CAUTION:
Do NOT use this COOLING mode when connecting to an indoor unit that does
not allow COOLING mode for any purpose other than pumping down.
