Charging Refrigerant
Charging for Gas
1. Connect the tap valve to the refrigerant tank.
2. Open the low pressure and adjust the low-side
reading below 4.2 kg/cm
2.
3. Place the refrigerant tank in the warm water
(40 °C) and keep the gas pressure in the refrigerant
tank higher than the gas pressure in the charging
valve.
4. Run the engine at high speed and operate A/C
system.
Notice: Place the refrigerant tank on the flat floor
to protect the liquid refrigerant from coming
through the suction inlet resulting in the
compressor’s damage.
5. Charge the specified amount to the charging valve
and close the low pressure valve.
Notice:
If the charging speed is low, it’s more efficient
to place the refrigerant tank in the warm water
(40 °C). But the temperature should keep below
(52 °C) at any situation.
Be careful not to contact the heating device or
material.
Charging for Liquid
Notice:
Do not operate when charging the system through
the high-side rpessure.
Do not open the low pressure valve when charging
the system by the liquid refrigerant.
1. Tighten both high pressure and low pressure
completely before evacuating the charging valve.
2. Connect the tap valve of the refrigerant tank.
3. Open the high pressure valve and turn the
refrigerant tank upside down.Single: 850 ± 50 g
Dual: 1200 ± 50 g
