MAINTENANCE AND SERVICE OPERATIONS
Lubricant oil
The compressor is lubricated by about 80±20 cc of ND8 oil. Only this type of oil (ND8)
should be used for topping up or oil changes.
In case of service operations which involve replacing some of the system components such as the con­
denser or the evaporator, 40 cc of oil must be added for each of the parts replaced. If the compressor is
being replaced, it is available as spares w i t h the recommended quantity of oil. For this reason, before fit­
ting it on the vehicle the amount of oil corresponding to that remaining in the system must be removed
first. In order to do this it is necessary to:

ing upwards).
1. Pour the quantity of oil in the compressor which is being replaced into a graduated test tube (C) tak­
ing care to let it drain well.
2. Pour the quantity of oil in the new compressor into a graduated test tube (D) taking care to let it drain
well.
3. Remove the excess quantity of oil(E) corresponding to the difference between the quantity of oil in
test tube (C) and test tube (D) (E = D - C).
The oil is extremely hygroscopic: avoid leaving the containers open.
Avoid leaving the compressor or any other component disconnected from the system for
longer than is necessary.
Do not tilt the compressor or turn it upsidedown.
