Evacuation and recharging (Air conditioning)

Evacuation and recharging

1. Add calculated refrigerant oil to the compressor as necessary.
2. Renew receiver/drier.
3. Connect a Refrigerant Station to the high and low pressure servicing connections.

CAUTION: Whenever the refrigerant system is opened, the receiver/drier must be renewed immediately before evacuating and recharging the system.

4. Operate the refrigerant evacuation system according to the manufacturers instructions.

NOTE: If the vacuum reading is below 700 mm/Hg after 15 minutes, suspect a leak in the system. Partially recharge the system and check for leaks using an electronic leak tester.

CAUTION: The system must be evacuated immediately before recharging commences. Delay between evacuation and recharging is not permitted.

5. Operate the refrigerant recharging system according to the manufacturers instructions.

Refrigerant required to charge system is: LHD vehicles - 650 grammes ± 50 grammes RHD vehicles - 700 grammes ± 50 grammes

6. If the full charge has not been accepted by the system, start the engine and run it at 1500 rev/min.
7. Switch on the air conditioning system, open the car windows, set the temperature control to cold and switch the blower to maximum speed.
8. Consult the Refrigerant Station Manual for the correct procedure to complete the charge.
9. Carry out the air conditioning system performance test.
