10.4 Refrigerant Charging Work

(1) Refrigerant charging

1) Remove the charging hose (green) 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 (green). Open the valve of the
charging hose (green). 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:
1.94 lb (0.88 kg)

CAUTION

The amount of refrigerant charged has a great
effect on the cooling and heating capacity of
the unit. Charge to the specified amount,
always observing the scale graduations while
charging.

5) Close the high pressure valve of the gauge

manifold and the valve of the refrigerant cylinder.
