Defrost Thermostat The defrost thermostat is located on the liquid line between the check/expansion valve and the distributor. When defrost thermostat…

8. Стр. 8 Pressure Switch Circuit

   Time−Delay Relay The defrost control incorporates a pressure switch circuit that allows the application of an optional high pressure switch. See figure 7. During a demand cycle, the defrost control will lock out the unit if the optional high pressure switch opens. The diagnostic LEDs will display a…

9. Стр. 9 B − Compressor (Reciprocating & Scroll)

   DANGER Make sure all power is disconnected before beginning electrical service procedures. Some HP29 units utilize a conventional reciprocating compressor. Table 6 shows the specifications of reciprocating compressors used in HP29 series units. TABLE 6 HP29 COMPRESSOR SPECIFICATIONS MAN/MODEL…

10. Стр. 10 1 − Compressor Cover (Figure 9)

    A compressor cover constructed of vinyl-faced fiberglass is used on all HP29 units. The cover provides an acoustic barrier. The cover slides over the compressor and is held secure with snap buttons. Slits are provided for installation around the discharge and suction lines. CONDENSER FAN MOTOR AND…

11. Стр. 11 LIQUID LINE SERVICE VALVE (VALVE OPEN)

    IMPORTANT INSERT HEX WRENCH HERE Service valves are closed to the heat pump unit and open to line set connections. Do not open until refrigerant lines have been leak tested and evacuated. All precautions should be exercised to keep the system free from dirt, moisture and air. STEM CAP SERVICE PORT…

17. Стр. 17 VI − REFRIGERANT LINE NOISE

    It is important to properly isolate the refrigerant lines to prevent unnecessary vibration. Line set contact with the structure (wall,ceiling or floor) causes some objectionable noise when vibration is translated into sound. The following illustrations demonstrates procedures which ensure proper…
