ADJUSTMENT

SERVICING PRECAUTIONS

Care must be taken when handling refrigeration
system components. Units must not be lifted by their
hoses, pipes or capillary lines. Hoses and lines must
not be subjected to any twist or stress. Ensure that
hoses are positioned in their correct run before fully
tightening the couplings, and ensure that all clips and
supports are used. Torque wrenches of the correct
type must be used when tightening refrigerant
connections to the stated value. An additional spanner
must be used to hold the union to prevent twisting of
the pipe.
Before connecting any hose or pipe ensure that
refrigerant oil is applied to the seat of the new ’0’ ring
but not to the threads.
Check the oil trap for the amount of oil lost.
All protective plugs on components must be left in
place until immediately prior to connection.
The receiver/drier contains desiccant which absorbs
moisture. It must be positively sealed at all times.

CAUTION: Whenever the refrigerant
system is opened, the receiver/drier must
be renewed immediately before evacuating

and recharging the system.

Use alcohol and a clean cloth to clean dirty
connections.
Ensure that all new parts fitted are marked for use
with R134a.

Refrigerant oil

Use the approved refrigerant lubricating oil:
V8 models up to 99MY: Sanden SP10
V8 models from 99MY and diesel models: Nippon
Denso ND-OIL 8

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

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
following quantities of refrigerant oil:

Condenser

40 cm

3

.......................................................

Evaporator

80 cm

.......................................................

Pipe or hose

20 cm

Receiver/drier

...................................................

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

NOTE: A new compressor should always
have its sealing caps in place and must
not be removed until immediately prior to

fitting

Fitting a new compressor
A new compressor is supplied with an oil fill (Xcm

3

) of:

V8 up to 99MY

150 cm

3

.......................................

V8 from 99MY

180 cm

.......................................

Diesel

140 cm

....................................................

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

1. Remove sealing plugs from the OLD

compressor.

2. Invert compressor and gravity drain oil into

measuring cylinder. Rotating the compressor
clutch plate will assist complete draining.

3. Note the quantity of oil drained (Ycm

3

).

4. Calculate the quantity (Qcm

3

) of oil to be drained

from the NEW compressor using the following
formula:

Xcm

3

- (Ycm

3

+ 20cm

3

) = Qcm
