9.2 Adding refrigerant
CAUTION:
Refrigerant charging must be performed after wiring,
vacuuming, and the leak testing.
DO NOT exceed the maximum allowable quantity of
refrigerant or overcharge the system. Doing so can damage
the unit or impact it’s functioning.
Charging with unsuitable substances may cause explosions or
accidents. Ensure that the appropriate refrigerant is used.
Refrigerant containers must be opened slowly. Always use
protective gear when charging the system.
DO NOT mix refrigerants types.
N=2(one-twin models), N=3(one-three models), N=4(one-four models), N=5(one-
fi ve models).
Depending on the length of connective piping or the pressure of the evacuated
system, you made need to add refrigerant. Refer to table below for refrigerant
amounts to be added:
Additional refrigerant per pipe length

Liquid Side: Ø 6.35 (ø 0.25”)
(Total pipe length - standard pipe lengthxN) x 15g/m
(Total pipe length - standard pipe lengthxN) x 0.16oZ/ft
Liquid Side: Ø 9.52 (ø 0.375”)
(Total pipe length - standard pipe lengthxN) x 30g/m
(Total pipe length - standard pipe lengthxN)x 0.32oZ/ft
