NOTE:For compressor applications, see COMPRESSOR APPLICATIONS article. DO NOT exceed A/C system refrigerant oil capacity, when servicing system. See REFRIGERANT OIL & REFRIGERANT SPECIFICATIONS article in GENERAL SERVICING.
Only new, moisture-free refrigerant oil should be used in the air conditioning system. This oil is highly refined and dehydrated so moisture content is less than 10 parts per million. The oil container must be tightly closed at all times when not in use, or moisture from the air will be absorbed into the refrigerant oil.
Drain, measure, and discard refrigerant oil from old compressor. Drain shipping oil from replacement compressor into a clean container. Add refrigerant oil to replacement compressor equal to amount drained from old compressor, plus 0.7 ounce.
If a sudden refrigerant discharge greater than 1.4 ounces has occurred, add 1.4 ounces of refrigerant oil after repairs. If a slow refrigerant leak less than 1.4 ounces has occurred, add 0.7 ounce of refrigerant oil after repairs. If any other components are replaced, add refrigerant oil as specified. See COMPONENT REFRIGERANT OIL CAPACITIES (MERCEDES-BENZ - NIPPONDENSO) table.
