Compressor Oil - Checking and Adjusting

^ The oil used to lubricate the compressor is circulating with the refrigerant.
^ Whenever replacing any component of the system and of a large amount of gas leakage occurs, add oil to maintain the original amount of oil.

Refrigerant Components:

Total amount of oil in the system: 150 ml (5.1 US fl oz, 5.3 Imp fl oz)

1. Connect oil separator KV994A9690 between compressor discharge side and condenser.
2. Evacuate and charge the system.
3. Operate compressor at engine idling with air conditioner set for maximum cooling and high fan speed.
4. Stop compressor operation after 10 minutes.

Never allow engine speed to exceed idling speed.

CAUTION: Do not continue compressor operation for more than 10 minutes.

5. Disconnect oil separator and connect refrigerant line to original positions.
6. Disconnect low flexible hose from compressor suction valve.
7. Add new oil from compressor suction port.

Amount of oil to be added: 120 ml (4.1 US fl oz, 4.2 Imp fl oz)

Adding Compressor Oil:

^ About 30 ml (1.0 US fl oz, 1.1 Imp fl oz) of oil remains unremoved in the system.

8. After adding oil, rotate compressor clutch by hand 5 to 10 turns.
9. Connect refrigerant line and evacuate and charge system.
10. Conduct leak test and performance test.
11. Gradually loosen drain cap of oil separator to release residual pressure. Remove cap and drain oil.
12. To prevent formation of rust and intrusion of moisture or dust, perform the following before placing the oil separator kit into storage.

1) Cap each opening of flexible hose and double union securely.
2) Cap oil separator, evacuate it from service valve, and charge refrigerant.

Compressor Oil - Adding Chart:

^ If oil separator is not available, add oil in accordance with the table.

1. With the compressor upside down, completely drain the oil through the suction port (from the embossed letter "s" mark side).

2. When the oil stops flowing out, rotate the clutch hub two or three times to completely drain the oil.
