8.4 To determine the additional refrigerant amount
For ARXM71R
If the total liquid piping
length is…
Then…
≤10m Do NOT add additional refrigerant.
>10m R=(total length (m) of liquid piping⁠–⁠10m)×0.035
R=Additional charge (kg) (rounded in units of
0.01kg)
For other outdoor units
If the total liquid piping
length is…
Then…
≤10m Do NOT add additional refrigerant.
>10m R=(total length (m) of liquid piping⁠–⁠10m)×0.020
R=Additional charge (kg) (rounded in units of
0.01kg)
INFORMATION
Piping length is the one-way length of liquid piping.
8.5 To determine the complete recharge amount
INFORMATION
If a complete recharge is necessary, the total refrigerant charge is: the factory
refrigerant charge (see unit name plate) + the determined additional amount.
8.6 To charge additional refrigerant
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.
