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.

Checking the compressor oil level (continued)
2/ Slow leak.
Slow leaks do not lead to oil loss, therefore the same procedure should be followed as if there was no leak at all.
3/ Fast leak.
This type of leak causes both oil loss as well as allowing air to enter the system.
It is therefore necessary to:
- Replace the dehydrator.
- Drain as much oil as possible
(when replacing the faulty component).
Either before or during filling of the system with R 134.afluid, introduce 80 ccof NEWoil into the circuit.
When changing one of the following components, add the quantity stated:
- A drying bottle : 15 ccof compressor oil.
- A condenser or an evaporator : 20 ccof compressor oil.
- High pressure or low pressure pipework : 5 ccof compressor oil.
- A drying cartridge : 15 ccof compressor oil.
