Description
To perform vacuum drying or a complete recharge of the outdoor unit's internal
refrigerant piping it is necessary to activate the vacuum mode which will open
required valves in the refrigerant circuit so the vacuuming process or recharge of
refrigerant can be done properly.
To activate/deactivate vacuum mode
Vacuum mode = Recovery mode. To activate/deactivate vacuum mode, see:
▪
"16.1.3 Recovery mode — In case of 3N~ models (7-segments
▪
"16.1.4 Recovery mode — In case of 1N~ models (7-LEDs
See
"8.3.3 Checking refrigerant piping:
WARNING
▪
Only use R32 as refrigerant. Other substances may cause explosions and
accidents.
▪
R32 contains fluorinated greenhouse gases. Its global warming potential (GWP)
value is 675. Do NOT vent these gases into the atmosphere.
▪
When charging refrigerant, ALWAYS use protective gloves and safety glasses.
NOTICE
To avoid compressor breakdown, do NOT charge more than the specified amount of
refrigerant.
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
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
