PLACING SYSTEM IN OPERATION
After component service or replacement has been completed, evacuate system thoroughly with a vacuum pump. Charge system with proper amount of refrigerant. See REFRIGERANT OIL & REFRIGERANT SPECIFICATIONS article in GENERAL SERVICING. Perform leak test. After system has been leak tested, check system operation.
Note. A/C systems normally will not need additional refrigerant oil unless oil loss has occurred due to ruptured lines, leaking compressor seals, compressor overhaul or component replacement.
A/C COMPRESSOR (ZEXEL ROTARY VANE) IDENTIFICATION
- Slowly discharge A/C system, using approved refrigerant recovery/recycling equipment. Remove old A/C compressor. Install compressor oil drain Adapters (SA9149AC-5 and SA9149AC-6) to service ports. 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.
- New compressors are shipped with 5 ounces of refrigerant oil and nitrogen gas. Open compressor sealing plugs slowly to release nitrogen gas. Drain and measure oil into a clean container (this oil will be used in new 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»(ref-119-S10459627302000030700000) table. Install compressor. Evacuate, charge and leak test A/C system. Ensure A/C system operates properly.
