The outdoor unit is factory charged with refrigerant, but in some cases the
following might be necessary:
What
Charging additional refrigerant
Completely recharging refrigerant
Charging additional refrigerant
Before charging additional refrigerant, make sure the outdoor unit's external
refrigerant piping is checked (leak test, vacuum drying).
INFORMATION
Depending on the units and/or the installation conditions, it might be necessary to
connect electrical wiring before you can charge refrigerant.
Typical workflow – Charging additional refrigerant typically consists of the following
stages:
1 Determining if and how much you have to charge additionally.
2 If necessary, charging additional refrigerant.
3 Filling in the fluorinated greenhouse gases label, and fixing it to the inside of
the outdoor unit.
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.
