How many grams of refrigerant does the Wuling Hongguang air conditioner need?

[LeEloise]

Wuling Hongguang air conditioner generally requires about 800 grams of refrigerant. The following is the method for charging from the low-pressure side of the Wuling Hongguang: 1. Connect the manifold pressure gauge to the compressor and the refrigerant tank. 2. Open the refrigerant tank, loosen the nut on the manifold pressure gauge for the middle charging hose until you hear the sound of refrigerant vapor flowing, then tighten the nut to expel the air in the charging hose. 3. Open the low-pressure manual valve to allow the refrigerant to enter the refrigeration system. When the system pressure reaches 0.4MPa, close the low-pressure manual valve. 4. Start the engine, turn on the air conditioning switch, and set the blower switch and temperature control switch to maximum. 5. Open the manual valve on the manifold pressure gauge to allow the refrigerant to continue entering the refrigeration system until the charging amount reaches the specified value. 6. After charging, close the low-pressure manual valve on the manifold pressure gauge, close the charging valve on the refrigerant tank, stop the engine, and quickly disconnect the manifold pressure gauge from the compressor to avoid excessive refrigerant leakage.
