System Maintenance
CLG835H
A/C system regular maintenance
A/C refrigerant filling method
Because air conditioning system is not an absolutely airtight system, the problem of deficient refrigerant
may occur after it is used for a period of time. At the moment, if refrigerant in the system is confirmed not
to completely lose, start the operation of refilling refrigerant starting from step X of the instructions.
Even though there is only little water in air conditioning system, water vapor at low temperature
part may be frozen to cause refrigerant circulation blockage or compressor valve corrosion, etc.
Therefore, when refrigerant is refilled after parts are replaced or air conditioning system is rein-
stalled in complete machine, strictly vacuum pumping, maintain pressure to check leakages and
continue to refill refrigerant after system airtightness is confirmed to be good.

Tools
1. Connect manifold gauge
and A/C filler according to
the sequence specified in
Release (Recover) Refriger-
ant in Air Conditioning Sys-
tem, and make sure there is
no refrigerant in the system.
2. Connect the hose connect-
ing port A on the manifold
gauge to vacuum pump.
