GENERAL INFORMATION

03-31

When a major repair has been completed, a leak test 
should be  conducted; refer to the air conditioning 
section of this manual for  the correct procedure.

Refrigerant oil
Use an approved refrigerant lubricating oil:

ND Oil 8

CAUTION: Do not use any other type of 
refrigerant oil.

CAUTION: Refrigerant oil easily absorbs water 
and must not be stored for  long periods. Do not 
pour unused oil back into the container.

When renewing system components, add the 
quantities of refrigerant oil recommended in the Air 
Conditioning section of this manual.

Compressor
A new compressor is sealed and pressurised with 
Nitrogen gas. When fitting a new compressor, slowly 
release the sealing cap; gas pressure should be 
heard to vent as the seal is broken.

CAUTION: A new compressor should always be 
sealed and could be pressurised with nitrogen 
gas. To avoid possible oil loss, release the 
sealing cap(s) slowly. Do not remove the cap(s) 
until immediately prior to connecting the air 
conditioning pipes to the compressor.

 Rapid refrigerant discharge
If the air conditioning system is involved in accident 
damage and  the system is punctured, the refrigerant 
will discharge rapidly. The rapid discharge of 
refrigerant will also result in the loss of most of  the 
oil from the system. The compressor must be 
removed and all the remaining oil in the compressor 
drained and refilled in accordance with the 'Air 
Conditioning Compressor Replacement Procedure'.

Air conditioning compressor 
replacement

A new compressor is supplied filled with a full charge 
of (X cm

3

) of refrigerant oil.

A new compressor is supplied with an oil fill (X cm) of 
120 cm

3

.

A calculated quantity of oil must be drained from the 
new compressor before fitting. To calculate the 
quantity of oil to be drained:

1 Remove the drain plug from the old 

compressor.

2 Invert the compressor and gravity drain the oil 

into a calibrated measuring cylinder. Rotate the 
compressor clutch to ensure the compressor is 
completely drained.

3 Note the quantity of oil drained (Y cm

3

).

4 Calculate the quantity of oil to be drained from 

the new compressor using the following 
formula:

X cm

3

 – (Y cm

3

 + 20 cm

3

) = Q cm

3

5 Remove the drain plug from the new 

compressor and drain Q cm

3

 of oil.

6 Fit and tighten the compressor drain plug.

System components
When renewing system components, add the 
following quantities of refrigerant oil: 

l

Condenser = 40 cm 

3

l

Evaporator = 30 cm 

3

l

Receiver drier = 15 cm

l

Pipe or hose = 5 cm
