Charging the A/C System

1. Open R-134a source valve(s) and allow 0.50 kg (1 lb.) of liquid R-134a to flow into system through low side service fitting.
2. As soon as 0.50 kg (1 lb.) has been added to system start engine, set the mode control to vent, temperature lever to full cold, blower speed on high, and push A/C compressor button to the On position (A/C control button light On). Slowly draw in the remainder of the refrigerant charge 0.23 kg (0.5 lb.). Total system charge is 0.68 kg (1.5 lbs.).
3. Turn off refrigerant source valve and run engine for 30 seconds to clear the lines and gauges.




4. With the engine running, remove the low side service valve from the suction pipe service port.

IMPORTANT: Make sure there is an O-ring seal inside of caps before installation because cap is primary seal for A/C service fittings. Failure to tighten cap will result in refrigerant leakage.




5. Install protective caps on service ports and hand tighten.
6. Turn engine Off.
7. Leak check system with electronic leak detector or equivalent.
8. With system fully charged and leak-checked, conduct a functional and performance test (refer to Diagnostic flow chart).
