Refrigerant Charging Work

Refrigerant charging
1) Remove the charging hose from the vacuum
pump, and connect it to the refrigerant
cylinder (R-410A).
2) Loosen the nut on the gauge manifold side
of the charging hose. Open the valve of the
charging hose. Open the valve of the
refrigerant cylinder. After air purging,
tighten this nut and close the valve of the
refrigerant cylinder.
3) Securely place the refrigerant cylinder on a scale with a weighing capacity of
70 lb (30 kg) that is graduated by 0.2 oz (5 g).
4) Open the high pressure valve of the gauge manifold and the valve of the
refrigerant cylinder. Charge the system with refrigerant to the specified amount.
Standard Amount of Refrigerant:
- XC-14A: Toshiba 15.9 oz (451 g), LG 15.5 oz (400 g)
- XC-22A: 42.3 oz (1200 g)
- XC-30A: 51.8 oz (1470 g)
CAUTION
5) Close the high pressure valve of the gauge manifold and the valve of the
refrigerant cylinder.
WARNING
•Do not attempt any repair on a charged system.
WARNING
•Before checking for gas leaks, fully confirm that there is nothing
flammable in the area to cause an explosion or fire. Contact of
refrigerant with an open fire generates toxic gas.
