Only for RZAG100~140.
To determine the additional refrigerant amount (R in kg) (in case of twin, triple
and double twin)
1 Determine G1 and G2.
G1 (m) Total length of <x> liquid piping
x=Ø9.5mm (standard)
x=Ø12.7mm (size‑up)
G2 (m) Total length of Ø6.4mm liquid piping
2 Determine R1 and R2.
If Then
G1>40m
(a)
Use the table below to determine R1
(length=G1−40m)
(a)
and R2 (length=G2).
G1≤40m
(a)
(and G1+G2>40m)

R1=0.0kg.
Use the table below to determine R2
(length=G1+G2−40m)
