Compressor HVAC: Service and Repair

Compressor Assembly And Tension Pulley:

CAUTION: As the compressor oil and receiver are highly moisture absorbent, use a non-porous material to plug the hose and nipples.

To prevent the entry of dust or other foreign bodies, plug the dismantled hoses and compressor nipples.

INSTALLATION SERVICE POINT

>>A<< COMPRESSOR INSTALLATION
If a new compressor is installed, first adjust the amount of oil according to the procedures described, and then install the compressor.

1. Measure the amount [X cu.cm (X fl.oz.)] of oil within the removed compressor.
2. Drain (from the new compressor) the amount [Y cu.cm (Y fl.oz.)] of oil calculated according to the following formula, and then install the new compressor.

New compressor oil amount=140 cu.cm (4.7fl.oz)

140 cu.cm - X cu.cm = Y cu.cm (4.7 fl.oz. - X fl.oz. = Y fl.oz.)

NOTE: Y cu.cm (Y fl.oz.) indicates the amount of oil in the refrigerant line, the condenser, the evaporator, etc.

NOTE: When replacing the following parts at the same times as the compressor, subtract the rated oil amount of the each part from Y cu.cm (Y fl.oz.) and discharge from the new compressor.

Quantity:
- Evaporator: 60 cu.cm (2.0 fl.oz.)
- Condenser: 15 cu.cm (0.5 fl.oz.)
- Suction hose: 10 cu.cm (0.3 fl.oz.)
- Receiver: 10 cu.cm (0.3 fl.oz.)
