Refrigerant Charging

Installation of manifold gauge

1. Close both high/low pressure hand valves of manifold
gauge before installation of gauge to the charging valve.
2. Both high/low pressure hand valves of manifold gauge
connect the appropriate charging valve. Tighten the hose
nuts by hand.
• High pressure hand valve → High pressure charging
valve
• Low pressure hand valve →Low pressure charging

Discharging refrigerant

1. Connect the manifold gauge to the charging valve.
2. Place the free end of the center hose in a shop towel.
3. Slowly open the high pressure hand valve and discharge
refrigerant.
Notice
If refrigerant is allowed to escape too fast, compressor
oil will be drawn out of the system.
4. Check whether the shop towel gets wet in oil and if wet,
Y220_10C020 close the hand valve.
5. After the high pressure gauge reading drops below 3.5
kg/cm 2
6. When both high and low pressure gauges reading drops
to 0 kg/cm

Evacuating Refrigeration System

Notice
The evacuation process for the air conditioner system
should be performed after discharing the refrigerant from
the charging valve. This operation is for eliminating all
the air and moisture in the system. Evacuate the system
around for 15 minutes and the opened components during
the service around for 30 minutes.
1. Make sure to turn off the engine.
2. Connect the manifold gauge set to the compressor gauge

fitting and close both valves.
3. Make sure to discharge the refrigerant from the charging
valve.
4. Connect the free end of the center hose to the intake
port in the vacuum pump.
, slowly open the low pressure valve.
