ZEXEL Rotary Vane: Saturn
- Slowly discharge A/C system, using approved refrigerant recovery/recycling equipment. Remove old A/C compressor. Drain compressor oil from high-side port first, and then low-side port. Rotate compressor clutch plate in both directions to remove oil from compressor. Measure oil amount drained, and discard oil.
- On "L" models, replacement compressors are shipped with 7.5 ounces of refrigerant oil and nitrogen gas. On "S" models, replacement compressors are shipped with 2.2 ounces of refrigerant oil and nitrogen gas. On all models, open compressor sealing plugs slowly to release nitrogen gas. Drain and measure oil into a clean container (this oil will be used in replacement compressor).
- Ensure amount of refrigerant oil in replacement compressor is the same as amount removed from old compressor plus amount removed during refrigerant recovery. This represents total system capacity, minus amount retained in components that have not been replaced. See ZEXEL COMPONENT REFRIGERANT OIL CAPACITIES table. Install compressor. Evacuate, charge and leak test A/C system. Ensure A/C system operates properly.
