System Practice Guide
Key practices for system installation and maintenance are outlined:
- System Cleanliness: Emphasizes removing impurities (moisture, burr, chemicals) and using de-hydrated, Nitrogen-charged components with bright annealed copper tubes.
- Brazing: Recommends purging with low-pressure Nitrogen, using flux, and employing appropriate brazing alloys (Phosphorous Copper for Copper-Copper, Copper-Silver for Copper-Steel).
- Leak Testing: Suggests using dry air or Nitrogen and electronic leak detectors. Advises against pressurizing with air and R134a.
- Evacuation: Details achieving a 200-micron vacuum level by pulling from both sides, heating the system, using short, large-diameter copper tubes for pump connection, and employing adequately sized two-stage rotary vacuum pumps with anti-suckback provision. Recommends never using a hermetic compressor for evacuation.
- Refrigerant Charging: Stresses the importance of quality and quantity, using genuine refrigerant sources, digital weigh balances, separate hoses for different refrigerants, and avoiding anti-choke devices.
- Compressor Mounting: Advises adequate torque on nuts, ensuring washers/bolt heads rest on sleeves, proper piping loops to avoid vibration and leaks, and notes that compressors are not suitable for mobile applications.
- Electricals: Recommends checking voltage across C & R terminals, using voltage stabilizers if supply is poor, using genuine accessories, proper earthing, and ensuring firm, insulated electrical joints.
- Attending Field Complaints: Advocates for verifying complaints with facts and tools, ruling out possibilities before replacing compressors, and analyzing the compressor's function before removal.
