10 SERVICE BY REFRIGERATION MECHANIC
10.1 Compressor recharge information
The ARB fridge freezer range as designated in this manual use refrigerant R134a.
10.2 Leaks in the refrigerant system.
If low refrigerant is suspected, the system should be pressure tested.
If the pressure test identifies a leak, the location of the leak should be found.
To locate the leak, the refrigerant system should be split into two sections (see below) and pressure
tested separately.
Section 1 - All refrigerant lines and components external to the foamed cabinet. This includes the
compressor and condenser.
Section 2 - The evaporator and all refrigerant lines inside the foamed cabinet.
If the refrigerant leak is located externally of the evaporator and foamed cabinet, the leak may be
repaired. If the fridge is inside the warranty period a complete replacement is required.
If a refrigerant leak is detected inside the evaporator or foamed cabinet, the fridge should be replaced.
