12.4. Complete recharging

In case complete recharging is required (after a leak, etc.), refer to 
the information below to determine the necessary amount of 
refrigerant.

12.5. Total charging weight of the refrigerant

 

(after a leak, etc.)

The total charging amounts relate to the refrigerant piping length as 
in "Maximum total one-way piping length" of the table in paragraph 

"8.4. Allowable pipe length and height difference" on page 8

. (E.g. 

twin: L1+L2).

Table 3: 

Total charging amount <unit: kg>

13. Pump down operation

This unit is equipped with an automatic pump down operation which 
will collect all refrigerant from the field piping and indoor unit in the 
outdoor unit. To protect the environment, make sure to perform the 
following pump down operation when relocating or disposing of the 
unit.

When in need of operation, turn off the main power supply and 
turn it on again. Make sure that stop valves both on liquid and 
gas side are open and be sure to operate the unit in cooling 
operation during test run.

NOTICE

Before recharging, make sure to execute vacuum drying of 
the internal piping of the unit as well. To do so, use the 
internal service port of the unit. Do NOT use the service 
ports located on the stop valve (se

"9.3. Stop valve 

operation" on page 10

), since vacuum drying can not be 

performed properly from these ports.

 

Outdoor units have 1 port on the piping. It is between the 
heat exchanger and the 4-way valve.

WARNING

Some sections of the refrigerant circuit may be isolated 
from other sections caused by components with specific 
functions (e.g. valves). The refrigerant circuit therefore 
features additional service ports for vacuuming, pressure 
relief or pressurizing the circuit.

In case it is required to perform 

brazing

 on the unit, ensure 

that there is no pressure remaining inside the unit. Internal 
pressures need to be released with ALL the service ports 
indicated on the figures below opened. The location is 
depending on mode type.

Procedure

Precaution

1

Make sure that stop valves both 

on liquid and on gas side are 

open.

2

Push the BS4 pumping-down 

operation button on the PC board 

of the outdoor unit (±8 seconds).

Compressor and outdoor fan will 

start operation automatically.

The indoor unit fan may 

automatically start running.

Please pay attention to this.

3

Close the stop valve on the liquid 

side securely about 2 minutes 

after the compressor started 

operation. (See 

"9.3. Stop valve 

operation" on page 10

.)

Never leave the outdoor unit 

unattended with opened front 

panel when power supply is on.

In case the stop valve on the 

liquid side is not securely closed 

during compressor operation, 

pumping-down operation cannot 

be executed.

4

Once compressor operation stops 

after 2 to 5 minutes

(a)

, close the 

stop valve on the gas side 

securely. (See 

"9.3. Stop valve 

operation" on page 10

.)

(a) If after finishing pumping-down operation the outdoor unit does not operate, not 

even when the remote controller switch is turned on, the remote controller may or 
may not indicate "

U4

". But this is not a malfunction.

5

Turn off the power supply.

WARNING

Make sure to re-open both stop valves before restarting 
operation of the unit.
