Charging additional refrigerant
The amount of additional refrigerant charging =
The amount of refrigerant charging for pipe +
the amount of refrigerant correction charging for an indoor unit.
1. The amount of additional refrigerant depending on the pipe size.
- Amount of additional refrigerant has to be calculated based on the sum of all liquid pipe length.

Additional refrigerant charging calculation = The sum of total length of Ø 9.52 liquid pipe(m) x 60 g + the sum of
total length of Ø 6.35 liquid pipe(m) x 20 g
Ex) a(Ø 9.52)=40 m, b+c+d(Ø 9.52)=15 m, e+f+g(Ø 6.35)=15 m
The amount of additional refrigerant = 55 m x 60g + 15 m x 20 g = 3600 g
2. The amount of additional refrigerant for each indoor unit.

Ex) When the indoor unit AM022FN1DEH and AM056FN4DEH are combinated
Additional refrigerant charging = 250g + 450g = 700g
3. The total amount of additional refrigerant charging = the amount of refrigerant charging for pipe + the amount of
refrigerant for each indoor unit.
Ex) The amount of additional refrigerant charging = 3600g + 700g = 4300g
