CONDITIONING

SPECIAL FEATURES: AIR CONDITIONING SYSTEM (R 134.a)

Compressor lubricant

ESSENTIAL: The compressor lubricant is extremely hygroscopic; always use FRESH oil.

Checking the compressor oil level

There are three specific cases:

- 1) Repairs to a system without leaks.

- 2) Slow leak.

- 3) Fast leak.

1) Repairing a system without leaks.

a) - Using draining/recovery equipment not fitted with an oil decanter.

- Drain the system as slowly as possible via the LOW PRESSURE valve, so as not to lose any oil.

- No more oil should be added when filling the system with R 134.a fluid.

b) - Using draining/filling equipment fitted with an oil decanter.

- Drain the R 134.a fluid from the system in accordance with the instructions in the equipment handbook.

- Measure the amount of oil recovered.

- Add the same amount of NEW oil when filling the system with R 134.a fluid.

c) - Replacing a compressor.

- Remove the old compressor, drain it and measure the oil quantity.

- Drain the new compressor (supplied full), so that the same amount of NEW oil is left in the compressor as was in the old compressor.

- No more oil should be added when filling the system with R 134.a fluid.
