IOM SYSPLIT MULTI EVO R32

Note On 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.
• For the R290 or R32 refrigerant model, make sure the condtions within the area have been
made safe by control of ammable material when the refrigerant added into air conditioner.
Refrigerant containers must be opened slowly. Always use protective gear when charging the
system.
•
• DO NOT mix refrigerants types.

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:
