Installation Instructions For Self-Contained Package Air Conditioners and Heat Pump Units *PC/*PH 13.4 SEER2 “H” SERIES With R-410A WARNING Only personnel that have been trained to install, adjust, service or repair(hereinafter, “service”) the equipment specified in this manual should service the equipment. The manufacturer will not be responsible for any injury or property damage arising from improper service or service procedures.

CODES AND REGULATIONS WARNING General The *PC & *PH series air conditioners and heat pumps are designed for OUTDOOR USE ONLY. This series is available in cooling Capacities of 2, 2 ½, 3, 3 ½, 4 and 5 nominal tons of cooling. Optional field installed heat kits are available in 5,8,10,15 and 20 KW. The units can be easily installed in manufactured or modular homes with existing highstatic duct work. The units can also be easily converted to accommodate a plenum for normal or low-static applications.
PAGE 4
MAJOR COMPONENTS The unit should be set on a solid, level foundation - preferably a concrete slab at least 4 inches thick. The slab should be above ground level and surrounded by a graveled area for good drainage. Any slab used as a unit’s foundation should not adjoin the building as it is possible that sound and vibration may be transmitted to the structure. For rooftop installation, steel or treated wood beams should be used as unit support for load distribution.

32.5:” and 36” SQRPCH103 (See Specification Sheets for Dimension details). The SQRPCH101 has 14” duct collar on supply and 16” duct collar (equivalent diameter, opening is oval) on the return. The SQRPCH102 and SQRPCH103 have 14” duct collar on supply and 18” duct collar (equivalent diameter, opening is oval) on the return. The collars are to be slipped into the openings, and the flanges bent around the converter. The square to round converter is attached to the flanges of the square duct openings.
PAGE 6
Plenum Application A suitable plenum or square duct must be constructed. The duct cross-sectional area should be determined by industry duct sizing manuals or air duct calculators. Install a branch circuit fused disconnect near the unit, in accordance with the N.E.C. or local codes. Wire sizes and overcurrent protection should be determined from the unit nameplate ampacity and in accordance with Table 4 (page 7) or the N.E.C.
PAGE 7
1. For branch circuit wiring (main power supply to unit disconnect), the minimum wire size for the length of the run can be determined from Table 4 using the circuit ampacity found on the unit rating plate. From the unit disconnect to unit, the smallest wire size allowable in Table 4 may be used for the ampacity, as the Disconnect must be in sight of the unit. 2. Wire size based on 60° C rated wire insulation and 30° C Ambient Temperature (86° F). 3.

Heat Pump Start-Up Procedure 9. Check the cooling mode for the heat pump in the same manner as above. The reversing valve is energized when the thermostat is placed in the cooling position. A clicking sound should be noticeable from the reversing valve. By lowering the temperature setting to call for cooling, the contractor is energized. The compressor, blower and fan should then be running. After the cooling mode is checked out, turn the thermostat system switch to “OFF”. 10.

Final System Checks 16. Check to see if all supply and return air grilles are adjusted and the air distribution system is balanced for the best compromise between heating and cooling. 17. Check for air leaks in the ductwork. 18. See Sections on Air Flow Measurement and Adjustment and Checking Charge. 19. Make sure the unit is free of “rattles”, and the tubing in the unit is free from excessive vibration. Also make sure tubes or lines are not rubbing against each other or sheet metal surfaces or edges.

SUGGESTED FIELD TESTING /TROUBLE SHOOTING When the solenoid valve coil is operated either from heating to cooling or vice versa, the piston in the reversing valve to the low pressure (high pressure) reverse positions in the reversing valve. 1. Run unit in the heating mode (room thermostat calling for heat). 2. Check unit for proper charge. NOTE: Bands of frost on the condenser coil indicate low refrigerant charge. 3. Shut off power to unit. 4.

In general 400 CFM per ton of cooling capacity is a rule of thumb. Some applications depending on the sensible and latent capacity requirements may need only 350 CFM or up to 425 CFM per ton. Check condition space load requirements (from load calculations) and equipment expanded ratings data to match CFM and capacity. The leads are factory connected as follows: Green to T1, Yellow to T2, and White to T3. T1 is the low speed setting and is dedicated to fan-only mode.

Subcooling Formula = Sat. Liquid Temp. - Liquid Line Temp. EXAMPLE: a. Liquid Line Pressure = 417 b. Corresponding Temp. °F. = 120° c. Thermometer on Liquid line = 109°F. To obtain the amount of subcooling, subtract 109°F from 120°F. The difference is 11° subcooling. See the specification sheet or technical information manual for the design subcooling range for your unit.

Inadequate Air Volume Through Indoor Coil When a heat pump is in the heating cycle, the indoor coil is functioning as a condenser. The return air filter must always be clean, and sufficient air volume must pass through the indoor coil to prevent excessive discharge pressure, and high pressure cut out. Indoor Blower motor speed tap selection may need to be modified to accommodate normal continuous operation to prevent a nuisance trip. See following table. *PCH/*PHH3(24-60) Models (0 - 0.5 E.S.P.

PACKAGE UNITS - HEAT PUMP AND AC UNITS HOMEOWNER’S Routine Maintenance Recommendations We strongly recommend a bi-annual maintenance checkup be performed by a qualified service agency before the heating and cooling seasons begin. Aluminum Indoor Coil Cleaning (Qualified Servicer Only) This unit is equipped with an aluminum tube evaporator coil. The safest way to clean the evaporator coil is to simply flush the coil with water.
