GENERAL INFORMATION
Precautions for refrigerant recovery, recycling
and recharging
Air Conditioning Compressor
Replacement
When the air conditioning system is recharged, any
existing refrigerant is first recovered from the system
and recycled. The system is then charged with the
required weight of refrigerant and volume of
refrigerant oil.
A new compressor is supplied filled with a full charge
(X cm
+
3
) of refrigerant oil.
CAPACITIES, FLUIDS, LUBRICANTS
AND SEALANTS, Capacities.A calculated quantity
of oil must be drained from the new compressor
before fitting. To calculate the quantity of oil to be
drained:
WARNING: Refrigerant must always be recycled
before re-use to ensure that the purity of the
refrigerant is high enough for safe use in the air
conditioning system.
1
Remove the drain plug from the old
compressor.
Recycling should always be carried out with
equipment which is design certified by
Underwriter Laboratory Inc. for compliance with
SAE J1991. Other equipment may not recycle
refrigerant to the required level of purity.
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.

Note the quantity of oil drained (Y cm ).

A R134a Refrigerant Recovery Recycling
Recharging Station must not be used with any
other type of refrigerant.
Calculate the quantity of oil to be drained from
the new compressor using the following
formula:
Refrigerant R134a from domestic and
commercial sources must not be used in motor
vehicle air conditioning systems.
X cm — (Y cm + 20 cm ) = Q cm
3 3 3 3
Remove the drain plug from the new
3
compressor and drain Q cm of oil. Fit and
tighten the compressor drain plug.
5
CAUTION: The system must be evacuated
immediately before recharging commences.
Delay between evacuation and recharging is not
permitted.
