WARNING
The refrigerant inside the unit is mildly flammable, but
normally does not leak. If the refrigerant leaks in the room
and comes in contact with fire from a burner, a heater, or a
cooker, this may result in fire, or the formation of a harmful
gas.
Turn off any combustible heating devices, ventilate the
room, and contact the dealer from which you purchased
the unit.
Do not use the unit until a service person confirms that the
portion from which the refrigerant leaked is repaired.
4.4.3 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.

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

L1=45 m (Ø9.5 mm)
RZAG100
Case: Twin, standard liquid pipe size
1 G1 Total Ø9.5 => G1=45 m
G2 Total Ø6.4 => G2=7+5=12 m
2 Case: G1>40 m
R1 Length=G1−40 m=5 m
=> R1=0.35 kg
R2 Length=G2=12 m
=> R2=0.4 kg

Case: Triple, standard liquid pipe size
1 G1 Total Ø9.5 => G1=15 m
G2 Total Ø6.4 => G2=20+17+17=54 m
2 Case: G1≤40 m (and G1+G2>40 m)
