CONDITIONING
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 PRESSUREvalve, so as not to lose any oil.
- No more oil should be added when filling the system with R 134.afluid.
b) - Using draining/filling equipment fitted with an oil decanter.
- Drain the R 134.afluid from the system in accordance with the instructions in the equipment handbook.
- Measure the amount of oil recovered.
- Add the same amount of NEWoil when filling the system with R 134.afluid.
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 NEWoil 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.
