National Codes

This product is designed and manufactured to permit installation in accordance with National Codes. It is the installer's responsibility to
install the product in accordance with National Codes and/or prevailing local codes and regulations.

General

The unit includes a hermetically sealed refrigerating system (consisting of a compressor, condenser coil, evaporator coil with flowrator),
an indoor blower, a condenser fan and all necessary internal electrical wiring. The heat pump also includes a reversing valve, solenoid,
defrost thermostat and control and loss of charge protection. The system is factory-evacuated, charged and performance tested. Refrigerant
amount and type are indicated on rating plate.

INSTALLATION

Pre-Installation Checkpoints

Before attempting any installation, the following points should be considered:
• 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 four sides of a home,
to minimize noise

Clearance

The unit is designed to be located outside the building with unobstructed
condenser air inlet and discharge. Additionally, the unit must be situated to
permit access for service and installation. Condenser air enters from three
sides. Air discharges upward from the top of the unit. Refrigerant gauge
connections are made on the right side of the unit as you face the compressor
compartment. Electrical connections can be made either on the right or left
sides of the unit. The best and most common application is for the unit to be
located 10" from wall (4" minimum) with the connection side facing the wall.
This "close to the wall" application minimizes exposed wiring.
Close to the wall application assures free, unobstructed air to the other two
sides. In more confined application spaces, such as corners provide a minimum
10" clearance on all air inlet sides. Allow 18" minimum for service access to
the compressor compartment and controls. The top of the unit should be
completely unobstructed. If units are to be located under an overhang, there
should be a minimum of 36" clearance and provisions made to deflect the warm
discharge air out from the overhang.

Location

Consider the affect of outdoor fan noise on conditioned space and any adjacent
occupied space. It is recommended that the unit be placed so that condenser air
discharge does not blow toward windows less than 25 feet away.
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.
Heat pumps require special location consideration in areas of heavy snow
accumulation and/or areas with prolonged continuous subfreezing temperatures.
Heat pump unit bases have holes under the outdoor coil to permit drainage of
defrost water accumulation. The unit must be situated to permit free unobstructed
drainage of the defrost water and ice. A minimum 2" clearance under the outdoor
coil is required in the milder climates.
