8.3. Refrigerant collecting (pump down)

Perform the following procedures to collect the refrigerant when moving the indoor 

unit or the outdoor unit.

1

  Supply power (circuit breaker).

  *   When power is supplied, make sure that “CENTRALLY CONTROLLED” is not 

displayed  on  the  remote  controller.  If  “CENTRALLY  CONTROLLED”  is  dis-

played, the refrigerant collecting (pump down) cannot be completed normally.

  *   Start-up of the indoor-outdoor communication takes about 3 minutes after the 

power  (circuit  breaker)  is  turned  on.  Start  the  pump-down  operation  3  to  4 

minutes after the power (circuit breaker) is turned ON.

2

  After the liquid stop valve is closed, set the SWP switch on the control board of 

the outdoor unit to ON. The compressor (outdoor unit) and ventilators (indoor and 

outdoor units) start operating and refrigerant collecting operation begins. LED1 

and LED2 on the control board of the outdoor unit are lit.

  *   Only set the SWP switch (push-button type) to ON if the unit is stopped. How-

ever, even if the unit is stopped and the SWP switch is set to ON less than 3 

minutes after the compressor stops, the refrigerant collecting operation cannot 

be performed. Wait until compressor has been stopped for 3 minutes and then 

set the SWP switch to ON again.

3

  Because the unit automatically stops in about 2 to 3 minutes when the refrigerant 

collecting operation is completed (LED1 off, LED2 lit), be sure to quickly close the 

gas stop valve. If LED1 is lit and LED2 is off and the outdoor unit is stopped, refrig-

erant collection is not properly performed. Open the liquid stop valve completely, 

and then repeat step 

2

 after 3 minutes have passed.

  *   If the refrigerant collecting operation has been completed normally (LED1 off, 

LED2 lit), the unit will remain stopped until the power supply is turned off.

4

 Turn off the power supply (circuit breaker).

  *   Note that when the extension piping is very long with large refrigerant amount, 

it may not be possible to perform a pump-down operation. When performing 

the pump-down operation, make sure that the low pressure is lowered to near 

0 MPa (gauge).

 Warning:

When pumping down the refrigerant, stop the compressor before disconnect

-

ing the refrigerant pipes. The compressor may burst if air etc. get into it.

8. Special Functions

1 2 3 4 5 6

*  Set the refrigerant address using the DIP switch of the outdoor unit.

1

  Wiring from the Remote Control

This wire is connected to TB5 (terminal board for remote controller) of the indoor 

unit (non-polar).

2

 When a Different Refrigerant System Grouping is Used.

Up  to  16  refrigerant  systems  can  be  controlled  as  one  group  using  the  slim  MA 

remote controller.

Note:

In single refrigerant system (twin/triple), there is no need of wiring
