Installation Of Hermetic Motor-Compressors
Replacement hermetic compressor motor is usually furnished with the following:
- The starting relay.
- Capacitors.
- Overload.
- Other accessories.
Use the exact replacements. These motor-compressors are intended for low, medium or high low side pressure. Use the same type, as he retired. Refrigerant the hole closed with service valves. Otherwise, the device may be provided with the short ends of the tubes. These are welded in place, with the ends of corrugated pipes and solder. Carefully install the motor-compressor. Use all safety precautions (lifting, special footwear, protection of floors and equipment). Install the mounting screws. Springs, shock absorbers, and anchor bolts must be in the correct position.
Installation of electric devices (overload and starting relay) and electric wires. All connections must be clean and tight. All the wires, insulation, including wire terminals, must be in good condition. Avoid connecting the aluminum wires for copper wires and copper rods.
Rapid corrosion occurs. Installing suction line and condenser. Units using the service valves are installed the same way as described for conventional compressor.
Tf soldered joints are used, determine the stub pipes. The difference between the pump suction, discharge connection tube process, and oil cooler connections. Cut out tube stubs with cutter. Select the connector fittings or landing tube. RSS outside of the dome. Connect the lines compressor lines. Clean the inside of the suction line and line capacitor. Solder joints. (This room should be well ventilated during the soldering process.) Set on the liquid line land and suction line land. Clean the joints with warm water to remove flux.
Install manifold. (Use to charge the stubs or valve mounted on the suction and liquid line.) Evacuate the system. Charge with refrigerant evaporates enough to build 15 psi pressure. Leak testing and repair of any, if it is found. Evacuate up to 50 microns up to 500 microns range within a few hours. Then charge the system.
Turn the power switch on the rim of the engine, check the temperature, pressure and electric energy. If any operation is not normal, be sure to make a diagnosis. Then remedy it before leaving work. Delete sendee connections and solder these joints. Clean pad...
