NOTICE
Make sure to open the stop valves after installing the refrigerant piping and
performing vacuum drying. Running the system with the stop valves closed may
break the compressor.
INFORMATION
After opening the stop valve, it is possible that the pressure in the refrigerant piping
does NOT increase. This might be caused by e.g. the closed state of the expansion
valve in the outdoor unit circuit, but does NOT present any problem for correct
operation of the unit.
7.5 Charging refrigerant
7.5.1 About charging refrigerant
The outdoor unit is factory charged with refrigerant, but in some cases you may
need to completely recharge refrigerant.
Example:
▪ When relocating the system.
▪ After a leak.
Completely recharging refrigerant
Before completely recharging refrigerant, make sure the following is done:
1 All refrigerant is recovered from the system.
2 The outdoor unit's external refrigerant piping is checked (leak test, vacuum
drying).
3 Vacuum drying on the outdoor unit's internal refrigerant piping is performed.
NOTICE
Before completely recharging, perform vacuum drying on the outdoor unit's internal
refrigerant piping as well.
Typical workflow – Completely recharging refrigerant typically consists of the
following stages:
1 Determining how much refrigerant to charge.
2 Charging refrigerant.
3 Filling in the fluorinated greenhouse gases label, and fixing it to the inside of
the outdoor unit.
7.5.2 About the refrigerant
This product contains fluorinated greenhouse gases. Do NOT vent gases into the
atmosphere.
Refrigerant type: R32
Global warming potential (GWP) value: 675
