7.6.5 Charging additional refrigerant
To determine the additional refrigerant amount
To determine if adding additional refrigerant is necessary
If Then
(L1+L2+L3+L4+L5+L6+L7)≤ chargeless
length
Chargeless length=
▪ 10m (size‑down)
▪ 40m (standard)
▪ 15m (size‑up)
You do not have to add additional
refrigerant.
(L1+L2+L3+L4+L5+L6+L7)> chargeless
length
You must add additional refrigerant.
For future servicing, encircle the
selected amount in the tables below.
INFORMATION
Piping length is the largest one-way length of liquid piping.
