9. Run engine at 1,500 rpm for at least 2 minutes.
10. Turn engine off and perform leak check again following steps 4
through 6 above.
Refrigerant leaks should be checked immediately after stopping
the engine. Begin with the leak detector at the compressor. The
pressure on the high pressure side will gradually drop after
refrigerant circulation stops and pressure on the low pressure
side will gradually rise, as shown in the graph. Some leaks are
more easily detected when pressure is high.
11. Before connecting the recovery/recycling equipment to the A/C system, check the recovery/recycling
equipment gauges. No refrigerant pressure should be displayed. If pressure is displayed, recover the
refrigerant from the equipment lines and then check the refrigerant purity.
12. Confirm the refrigerant purity in the supply tank using the recovery/recycling equipment and the refrigerant
identifier equipment.
13. Confirm the refrigerant purity in the A/C system using the recovery/recycling equipment and the refriger-
ant identifier equipment.
14. Discharge the A/C system using approved refrigerant recovery equipment. Repair the leaking fitting or
component as necessary.
15. Evacuate and recharge the A/C system and perform the leak test to confirm there are no refrigerant leaks.
16. Conduct the A/C performance test to ensure that the system works properly. Refer to MTC-67, "
