1. Стр. 1 HS29

   Corp. 9715−L9 Service Literature HS29 SERIES UNITS The HS29 is a residential split-system condensing unit. Condensing coil size, circuiting and air volume result in a minimum SEER rating of 10.0. The series is designed for use with an expansion valve or RFCIV system in the indoor unit. However, the…

5. Стр. 5 TABLE 1

   I − UNIT INFORMATION HS29 condensing units are available in 1, 1 -1/2, 2, 2 -1/2, 3, 3 -1/2, 4 and 5 ton capacities. All major components (indoor blower/coil) must be matched according to Lennox recommendations for the compressor to be covered under warranty. Refer to the Engineering Handbook for…

6. Стр. 6 5 − Fan Capacitor C1

   The fans in three-phase HS29−413, −463, −513, −653, −683, units use permanent split capacitor motors. A single capacitor C1 is used for the fan motor. The capacitor is located inside the unit control box (see figure 1). Table 3 shows the ratings of C1. TABLE 3 HS29 FAN CAPACITOR RATING (C1) HS29…

7. Стр. 7 Three-Phase Compressor Rotation

   2 − Compressor Cover (Figure 5) Three-phase scroll compressors must be phased sequentially to ensure correct compressor rotation and operation. At compressor start-up, a rise in discharge and drop in suction pressures indicates proper compressor phasing and operation. If discharge and suction…

8. Стр. 8 III − REFRIGERANT SYSTEM

   A − Plumbing B − Service Valves Field refrigerant piping consists of liquid and suction lines from the condensing unit (sweat connections) to the indoor evaporator coil (flare or sweat connections). Use Lennox L10 (flare) or L15 (sweat, non−flare) series line sets as shown in table 6 or table 7 or…

10. Стр. 10 IV − CHARGING

    The unit is factory−charged with the amount of HCFC−22 refrigerant indicated on the unit rating plate. This charge is based on a matching indoor coil and outdoor coil with a 20 foot (6.1 m) line set. For varying lengths of line set, refer to table 8 for refrigerant charge adjustment. A blank space…

11. Стр. 11 D − Charging

    If the system is completely void of refrigerant, the recommended and most accurate method of charging is to weigh the refrigerant into the unit according to the total amount shown on the unit nameplate. Also refer to the SPECIFICATIONS tables on pages 1 and 2. If weighing facilities are not…

12. Стр. 12 2 − RFCIV Systems

    E − Oil Charge Refer to table 4 on page 6 and table 5 on page 7. The following procedures are intended as a general guide for use with RFCIV systems only. For best results, indoor temperV − MAINTENANCE ature should be between 70°F and 80°F (21.1°C and 26.7°C). At the beginning of each heating or…
