Check the hose and connection status of manifold gauge.
Then, check if there is a pin at the end of low pressure hose
(
③ ). Valves of low and high pressure hoses ( ① , ② ) must be
closed.
Connect hose in the middle of manifold gauge (
④
) to
refrigerant container (
⑤
). Refrigerant container must be
prepared so that refrigerant can be charged in gaseous state.
While placing low pressure hose of manifold gauge ( ③ ) over
the service port of gas service valve (
⑥
), open the valve of
refrigerant container ( ⑤ ), slightly open low pressure valve of
manifold gauge ( ① ) and remove air from inside the hose
(
③
). Immediately after removing air, connect
③
and
⑥
and
close the low pressure valve of manifold gauge ( ① ).
Start cooling operation of air conditioner.
Open and close low pressure valve (
①
) by checking the
pressure of manifold gauge. Repeat pressure check and
additionally fill up refrigerant according to the pressure listed
Close low pressure valve of manifold gauge ( ① ) and stop the
operation of air conditioner.
After closing the valve of refrigerant container, disconnect
manifold gauge and reassemble nut caps and port caps (to
prevent refrigerant leakage).
