Page 36: Note On Adding Refrigerant
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. - Page 37 Only for Australia models : • DO NOT mix refrigerants types. N=2(one-twin models),N=3(one-three models),N=4(one-four models),N=5(one- ve models). Some systems require additional charging depending on pipe lengths. The standard pipe length is 10m. The additional refrigerant to be charged can be calculated using the following formula: ADDITIONAL REFRIGERANT PER PIPE LENGTH Connective Pipe Air Purging...
