Fluid Reservoir or Reservoir and Restrictor

Fluid Reservoir or Reservoir and Restrictor

Contaminants Removed from Refrigerant Circuit
- Discharge refrigerant circuit
- Remove A/C compressor.
- Rectify cause of trouble.
- Examine expansion valve for dirt or corrosion; replace if necessary
- Remove oil drain plug from A/C compressor.

NOTE: The oil drain plug of "Denso/Nippondenso" compressors is equipped with an oil seal instead of an O-ring and this is always to be replaced.

- To accelerate drainage of refrigerant oil, rotate compressor e.g. by way of clutch plate of A/C clutch for example.
- Pour old refrigerant oil out of A/C compressor.
- Then fill compressor with quantity of fresh refrigerant oil corresponding to quantity of refrigerant oil in original part compressor.

NOTE:
- Which refrigerant oils and quantities are used for the various compressors.
- To ensure compressor lubrication on start-up, at least 80 cu.cm of refrigerant oil must be poured into the compressor, the remainder can be added for example to the new reservoir or receiver.
- If dirt has penetrated into the compressor with the refrigerant circuit open (e.g. after an accident), compressor is to be replaced.

- Replace receiver or accumulator and restrictor.
- Assemble, evacuate and charge refrigerant circuit.

Replacing Reservoir, No Contaminants, No Loss of Refrigerant
- Discharge refrigerant circuit
- Replace restrictor.
- Remove receiver or accumulator.
- Remove dirt from receiver or reservoir.
- Weigh receiver or reservoir removed.

NOTE:
- Add refrigerant oil to new receiver or reservoir until weight of component removed has been attained.
- Install new receiver or reservoir.

- Assemble, evacuate and charge refrigerant circuit.
