Air Evacuation NOTE: If there is no change in system pressure, Preparations and Precautions unscrew the cap from the packed valve (high Air and foreign matter in the refrigerant circuit can pressure valve). If there is a change in system pressure, there may be a gas leak.
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.

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...

Function of Automatic Wiring/Piping Correction Automatic Wiring/Piping Correction Function More recent models now feature automatic correction of wiring/piping errors. Press the "check switch" on the outdoor unit PCB board for 5 seconds until the LED displays "CE”, indicatomg that this function is working, Approximately 5-10 minutes after the switch is pressed, the "CE" disappears, meaning that the wiring/piping error is corrected and all wiring/piping is properly connected.
