Fitting a new compressor

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 it’s sealing cap in place and must not be removed until immediately prior to fitting.

A new compressor is supplied with an oil fill quantity₃₃ (Xcm ) of 135 cm . A calculated quantity of oil must be drained from a new compressor before fitting.

To calculate the quantity to be drained:

1. Remove the drain plug from the old compressor.
2. Invert compressor and gravity drain the oil into a calibrated measuring cylinder. rotating the compressor clutch plate will assist complete draining.₃
3. Note the quantity of oil drained (Ycm )
4. Calculate the quantity of oil to be drained from the NEW compressor using the following formula:

X cm3- (Y cm3 + 20 cm3) = Q cm3

5. Remove drain plug from new compressor and₃ drain Qcm of oil. Fit and tighten compressor drain plug.

Fitting an existing compressor

When refitting an existing compressor a quantity of refrigerant oil equivalent to the amount obtained when the system was discharged must be added to the compressor.

Use only an approved refrigerant lubricating oil:

Sanden SP-10 Unipart SP-10

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.
