It is the installer’sresponsibility to install the product in accordance with NationalCodes and/or prevailing local codes and regulations.MAJOR COMPONENTSThe unit includes a hermetically sealed refrigerating system(consisting of a compressor, condenser coil, evaporator coil withflowrator), an indoor blower, a condenser fan and all necessaryinternal electrical wiring. The heat pump also includes a reversingvalve, solenoid, defrost thermostat and control and loss of chargeprotection. The system is factory-evacuated, charged andperformance tested. Refrigerant amount and type are indicatedon rating plate.PREINSTALLATION CHECKSBefore attempting any installation, the following points should beconsidered: Structural strength of supporting members Clearances and provision for servicing Power supply and wiring Air duct connections Drain facilities and connections Location may be on any 4 sides of a home, manufactured ormodular, to minimize noise.Clearances and AccessibilityThe unit is designed to be located outside the building withunobstructed condenser air inlet and discharge. Additionally, theunit must be situated to permit access for service andinstallation. Condenser air enters from 3 sides. Air dischargesupward from the top of the unit. Refrigerant gauge connectionsare made on the right side of the unit as you face the compressorcompartment. Electrical connections can be made either on theright, bottom or duct panel side of the unit. The best and mostcommon application is for the unit to be located 10" (25.4 cm)from the wall (4" [10.2 cm]) minimum) with the connection sidefacing the wall. Close to the wall application minimizes exposedwiring.3
Close to the wall application assures free, unobstructed air to theother 2 sides. In more confined application spaces, such ascorners, provide a minimum 10" (25.4 cm) clearance on all airinlet sides. Allow 18" (45.7 cm) minimum for service access to thecompressor compartment and controls. The top of the unitshould be completely unobstructed. If units are to be locatedunder an overhang, there should be a minimum of 36" (91.4 cm)clearance and provisions made to deflect the warm discharge airout from the overhang. To avoid possible property damage or personal injury, theroof must have sufficient structural strength to carry theweight of the unit(s) and snow or water loads as required bylocal codes. Consult a structural engineer to determine theweight capabilities of the roof.The unit may be installed directly on wood floors or on ClassA, Class B or Class C roof covering material.To avoid possible personal injury, a safe, flat surface forservice personnel should be provided.Rooftop InstallationUnit LocationConsider the affect of outdoor fan noise on conditioned spaceand any adjacent occupied space. It is recommended that theunit be placed so that the condenser air discharge does not blowtoward windows less than 25 ft (7.6 m) away. Considerationshould also be given to shade and unit appearance.Heat pumps require special location consideration in areas ofheavy snow accumulation and/or areas with prolongedcontinuous subfreezing temperatures. Heat pump unit baseshave holes under the outdoor coil to permit drainage of defrostwater accumulation. The unit must be situated to permit freeunobstructed drainage of the defrost water and ice. A minimum2" (5 cm) clearance under the outdoor coil is required in themilder climates.Ground Level Preinstallation DetailsThe unit should be set on a solid, level foundation—preferably aconcrete slab at least 4" (10.2 cm) thick. The slab should beabove ground level and surrounded by a graveled area for gooddrainage. Any slab used as a unit’s foundation should not adjointhe building as it is possible that sound and vibration may betransmitted to the structure.Ground Level InstallationRoof Curb Installations OnlyNOTE: Sufficient structural support must be determined prior tolocating and mounting the curb and package unit.Curb insulation, cant strips, flashing and general roofing materialare furnished by the contractor.Curbing must be installed in compliance with the NationalRoofing Contractors Association Manual.
