Evacuating and Charging

CHARGE THE SYSTEM

1. With the refrigerant source connected and the service hose purged, slowly open the low-pressure manifold valve, while checking the low-pressure gauge reading.

CAUTION: The refrigerant source must be positioned for vapor (valve up).







2. Keep the low side pressure below 276 kPa (2.81 kg/sq.cm, 40 psi) by using the low-pressure manifold valve to regulate the flow of refrigerant into the system.
3. When the system is fully charged, close the low-pressure manifold valve.
4. Close the valve at the refrigerant source.
