CHARGE (g/m)
Method
1. Calculate the refrigerant charge to be added considering the parameters specified in
the "LENGTH OF REFRIGERANT CONNECTIONS" section in this manual.
2. Connect the R32 refrigerant cylinder in a position where the liquid can be Charged
into the pressure gauge unit valve where the nitrogen cylinder or the vacuum pump
has been collected.
3. Connect the pressure gauge unit to the outdoor unit charging valve (gas). when
injecting the liquid refrigerant through the gas valve, you must act slowly and pay
attention so as to prevent liquid hammer to the compressor.
4. Place the refrigerant cylinder on an electronic scale.
5. Open the valve to allow the refrigerant to pass through.
6. Close the valve when the weight of the cylinder coincides with the amount to be
charged.
