Prerequisite: Before completely recharging refrigerant, make sure the system is
pumped down, the outdoor unit's external refrigerant piping is checked (leak test,
vacuum drying) and vacuum drying on the outdoor unit's internal refrigerant
piping is performed.
1 If not already done (for vacuum drying of the unit), activate the vacuum mode
(see
"To activate/deactivate the vacuum mode field setting" [
4
55])
2 Connect the refrigerant cylinder to the service port of the liquid stop valve.
3 Open the liquid stop valve.
4 Charge the complete refrigerant amount.
5 Deactivate the vacuum mode (see "To activate/deactivate the vacuum mode
field setting" [
4
55]).
6 Open the gas stop valve.

f GWP = Global warming potential
NOTICE
Applicable legislation on fluorinated greenhouse gases requires that the refrigerant
charge of the unit is indicated both in weight and CO
2
equivalent.
Formula to calculate the quantity in CO
2
equivalent tonnes: GWP value of the
refrigerant × total refrigerant charge [in kg] / 1000
Use the GWP value mentioned on the refrigerant charge label.
2 Fix the label on the inside of the outdoor unit. There is a dedicated place for it
on the wiring diagram label.
