- As the DA-6 compressor has no oil sump, the compressor retains a minimum of refrigeration oil. Therefore, only the accumulator needs to be removed, drained, and its oil measured.
- If the amount recovered is less than 3 ounces, add 3 ounces of new oil to the system. If the amount is more than 3 ounces, add the same amount of new oil as that drained from the accumulator.
NOTE:
If a new accumulator must be added to the DA-6 system, add an additional 3 ounces to compensate for that retained by the original accumulator desiccant.
