Refrigerant Charging Work

A. Refrigerant Charging
(1) Remove the charging hose (green)
from the vacuum pump, and connect
it to the refrigerant cylinder (R-22).
(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 refrig-
erant cylinder.
(3) Securely place the refrigerant cylinder
on a scale with a weighing capacity of
70 lbs (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 speci-
fied amount.

Standard Amount of Refrigerant:

1.50lbs (0.68kg)
If the system cannot be charged with
the specified amount of refrigerant
under this condition, follow the steps
below:
(a) Close the high-pressure valve of
manifold.
(b) Operate the refrigerant system.
(c) Slowly open the low-pressure valve
while observing the scale reading.
(d) When the scale reads the specified
amount, immediately close the low-
pressure valve.
(e) Bring the system to a stop.
CAUTION: The amount of refrigerant charged
has a great effect on the cooling 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.
