Signs Of Excessive Oil Leakage
If system has lost excessive oil, remove accumulator. Drain and measure oil. If more than 3 ounces is measured, replace the same amount of new oil as was drained. If less than 3 ounces is measured, add 3 ounces of new oil. Add and additional 2 ounces of new oil to compensate for that lost by replacing the accumulator (held in desiccant).
NOTE:
If the exact oil charge is in doubt, drain and flush system. Add a new 6-ounce charge of refrigerant oil to the system.
