EPA Regulations

Important: The United States Environmental
Protection Agency (EPA) has issued various
regulations regarding the introduction and
disposal of refrigerants in this unit. Failure
to follow these regulations may harm the
environment and can lead to the imposition of
substantial fines. Because regulations may vary
due to passage of new laws, we suggest a certified
technician perform any work done on this unit.
Should you have any questions please contact the
local office of the EPA.

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.

MAJOR COMPONENTS

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,
manufactured or modular, 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 12" from the 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 12" clearance
on all air inlet sides. Allow 36" 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 48" clearance and provisions made to deflect the warm
discharge air out from the overhang. See FIGURE 1:
GROUND LEVEL INSTALLATION below.
Figure 1: Ground Level Installation

Unit Location

Consider the effect 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 of 2" clearance under the outdoor coil is
required in milder climates.
