CAUTION:
If charging liquefied refrigerant into system with the can
turned upside down to reduce charging time, charge it only
through high-pressure (discharge) service valve. After charg-
ing, the compressor should always be turned several times
manually.
2) When low-pressure gauge reading is 98 kPa (0.98 bar, 1.0
kg/cm2, 14 psi), completely close high-pressure valve of
manifold gauge and stop charging.
Evacuating the ~ ~ s t e r n - m
1. Close manifold gauge valve securely and disconnect charg-
ing hose from refrigerant can.
2. Connect center charging hose to vacuum pump.
3. Start pump, then open both valves and run pump for about
20 minutes.

refrigerant into system.
2) When refrigerant charging speed slows down, close high-
pressure valve of manifold gauge and open low-pressure
valve of manifold gauge and charge refrigerant while running
the compressor for ease of charging.
3) Start engine
