19 Charging refrigerant
In this chapter
19.1 About charging refrigerant
The outdoor unit is factory charged with refrigerant, but depending on the field
piping you have to charge additional refrigerant.
Before charging refrigerant
Make sure the outdoor unit's
external
refrigerant piping is checked (leak test,
vacuum drying).
Typical workflow
Charging additional refrigerant typically consists of the following stages:
1
Determining how much you have to charge additionally.
2
Charging additional refrigerant (pre-charging and/or charging).
3
Filling in the fluorinated greenhouse gases label, and fixing it to the inside of
the outdoor unit.
