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
Connective Pipe
