6.2. Note On Adding Refrigerant
•
Refrigerant charging must be performed after wiring, vacuuming and the leak test.
•
DO NOT exceed the maximum allowable quantity of refrigerant or overcharge the system. Doing so
can damage or impact the unit’s function.
•
Charging with unsuitable substances may cause explosions or accidents. Ensure that the appropri-
ate refrigerant is used.
•
Refrigerant containers must be opened slowly. Always use protective gear when charging the sys-
tem.
•
DO NOT mix refrigerants types.
Some systems require additional charging depending on pipe lengths L (m).
