With Bulk Container

1. Warm engine to operating temperature. Turn A/C "OFF."
2. With R-12 drum inverted, open valve and allow 1 lb. of liquid R-12 to flow into system through low-side service fitting.
3. When 1 lb. of refrigerant has entered system, turn drum upright and engage compressor to draw in remainder of charge. Cooling condenser with a large fan will speed up charging procedure by maintaining condenser temperature below charging cylinder temperature.
4. Close refrigerant supply valve and run engine for 30 seconds to clear lines and gauges.
5. With engine running, remove charging low side hose adapter from service fitting.

NOTE: Do not remove gauge line from adapter when line is connected to A/C system. To disconnect line, always remove line adapter from service fitting. Do not remove charging hose at gauge set while attached to service fitting. System will be discharged due to depressed Schrader valve.

6. Replace protective cap on service fitting and turn engine off.
7. Check system for leaks.
8. Start engine and check for proper system pressures.
