Oil Charge Additions
OIL CHARGE-COMPONENT REPLACEMENT
If there are no signs of external oil leakage, proceed as follows to add oil to system during component replacement.
1. Discharge system, as outlined, and measure amount of oil collected in discharge container. The amount of oil collected when discharging system must be replaced with new refrigeration oil to maintain proper oil charge.
2. Remove defective components. Measure amount of oil remaining in compressor, if removed.
3. Add proper amount of new refrigeration oil to each replacement component as follows:
a. If compressor is replaced, drain replacement compressor and add the same amount of oil as was drained from defective compressor.
b. If condenser is replaced, add 1 ounce of oil to replacement condenser.
c. If evaporator is replaced, add 2 ounces of oil to replacement evaporator.
d. If filter/drier is replaced, add 1 ounce of oil to replacement filter/drier.
4. Install replacement components, then evacuate and recharge system.
