Features and Benefits
Standard Features
• Operating Efficiency - All heat pump units provide
operating efficiencies of 13 SEER and 7.7 HSPF. All
efficiencies exceed legislated minimum levels.
• On Site Flexibility - All model sizes share a common,
compact design cabinet in a single footprint. The installer
has the flexibility of setting one curb and placing the
proper tonnage unit on that curb after the internal load has
been determined. Field convertible duct connections from
side shot to down shot allows the installer to have greater
flexibility with less inventory.
• Lower Installation Cost - Installation time and costs are
reduced by easy power and control wiring connections.
The small base dimension means less space is required
on the ground or roof, plus, the installer can fit this unit
between the wheel wells of full size pick-up truck.
• All units are completely wired, charged with R-410A and
tested prior to shipment. Unique test stations using a new
state of the art computerized process system are used to
insure product quality. Refrigerant charge and component
part numbers are verified via computers at assembly. Vital
run test statistics such as system pressure, motor
currents, air velocity and temperature, unit vibration, and
gas system safeties are monitored and recorded by the
system to insure unit performance.
• Equal size, side supply and return duct connections
allows easy hook-up of ducts to match low crawl spaces
without transition pieces.
• Utility Connections Made Easy - Electric utility
knockouts are provided through the bottom as well as the
side of the unit. Utility connections can be made quickly

and with a minimum amount of field labor. A field supplied
and field installed electrical disconnect switch must be
installed.
• Convertible Airflow Design - The bottom duct openings
are covered when they leave the factory ready to be used
for a side supply/side return application. If a bottom
supply/bottom return application is desired, you simply
remove the two panels from the bottom of the unit and
place them in the side supply/side return duct openings.
No panel cutting is required and no accessory panel is
necessary. Convertible airflow design allows maximum
field flexibility and minimum inventory.
• Condensate Pan - A non-corrosive, long-lasting, watertight pan is positioned below the evaporator coil to collect
and drain all condensate. Less collection of stagnate
condensate will build-up. The condensate pan conforms
to ASHRAE 62-89 standards (Ventilation for Acceptable
Indoor Air Quality).
• Condensate Drain - The 3/4 inch NPTF connection is
rigidly mounted to assure proper fit and leak tight seal.
• Durable Finish - The cabinet is made of pre-painted
steel. The pre-treated galvanized steel provides a better
paint to steel bond, which resists corrosion and rust creep.
Special primer formulas and matted-textured finish insure
less fading when exposed to sunlight.
• Full Perimeter Base Rails - The easily removable base
rails provide a solid foundation for the entire unit and
protects the unit during shipment. The rails provide fork lift
access from all sides, and rigging holes are also provided
so that an overhead crane can be used to place the units
on a roof. On applications where the unit is placed on a
pad, the base will keep the unit off the pad to deter
corrosion. On applications where height is limited, the inch
high base rails may be removed on location.

• More Attractive Appearance - A single piece Water
Shed top cover containing a top discharge condenser fan
arrangement requires less square footage on installation
and provides a wider variety of installations. The one
piece design adds greater water integrity. Rounded
corners with water drip edges add to the attractive
appearance. The cabinet panels have a non-fibrous
insulation that will not release insulation fibers into
conditioned area.
• Top Discharge - The top discharge condenser fan does
not disrupt neighboring areas or dry-out vegetation
surrounding the unit. The warm air from the top mounted
fan is blown up away from the structure and any
landscaping. This allows compact location on multi-unit
applications.
• Condenser Coil Grille - All 13 SEER models utilize a
decorative “Wire Form” coil guard to provide impact
protection against large objects.
• Low Operating Sound Level - The upward air flow
carries the normal operating noise up and away from the
living area. The rigid top panel effectively isolates any
motor sound. Isolator mounted compressor and the
rippled fins of the condenser coil muffle the normal fan
motor and compressor operating sounds. The unique
formed base pan also aids in sound alterations with it's
Super-Structure design. This design strategically places
embossments in the pan for optimum strength and rigidity.
• Fan System - All models operate over a wide range of
design conditions with an electrically commutated fan
motor. These units easily match all types of applications
and provide greater on site flexibility to match comfort
requirement. The cooling speed is factory set and can be
field adjusted to a second speed. The heating speed is
factory set to maintain mid point rise at the units heating
input, but can be field adjusted. This allows maximum
comfort conditions.
• Simple Control Circuit - A low voltage printed circuit
board contains a diagnostic indicator light and a low
voltage terminal strip. An additional set of pin connectors
is also provided to simplify the field interface of external
controls. Mate-n-lock plug connectors are used. The
electrical control box is not located in the compressor
compartment. The controls are mounted on a Control-Tilt
control panel to allow the access cover to be removed for
trouble shooting and maintenance without affecting the
normal system operating pressures. All wiring internal to
the unit is color/number coded.
• Protected Compressor - The compressor is internally
protected against high pressure and temperature. This is
accomplished by the simultaneous operation of high
pressure relief valve and a temperature sensor which
protect the compressor if undesirable operating conditions
occur.
• Pressure Switches - High pressure and low pressure/
loss of charge switches standard in all units. When
abnormal conditions are sensed through the pressure

4

switches, the unit will lock out preventing any further
operation until reset or problem is corrected.
• Exclusive Coil Design - Grooved copper tubes and
enhanced aluminum fin construction improves heat
transfer for maximum efficiency and durability.
• Low Maintenance - Long life, permanently lubricated
condenser and evaporator fan motor bearings need no
annual maintenance adding greater reliability to the unit.
Blower assembly can be easily cleaned by the unique
Slip- Track slide-out blower assembly.
• Secured Service Access Ports - Protected, externally
mounted, re-usable service access ports are provided on
both the high and low lines for ease of evacuating and
charging the system. No final field mounting required.
• Easy Service Access - A large, single panel covers the
electrical and gas controls makes servicing easy. The
blower compartment has an additional large panel with a
built-in handle tab. Removing this panel will allow the
blower assembly to slide-out for easy removal for
maintenance and ease of trouble shooting.
• Replacement Parts - The installer requires no special
training to replace any of the components of these units
and does not need to maintain an inventory of unique
parts.
• System Integration - Each unit has the internal ability to
integrate an electronic air cleaner or humidifier to work in
conjunction with the base unit.

Field Installed Accessories
• Economizer Down Discharge/Supply Kit - Modulating
integrated economizer provides simultaneous operation
between the mechanical cooling and economizer
operation. Independent blade design insures proper
control and less than 1% leak rate. Includes hood and
mesh bird screen filter integrated into the hood, dry bulb
sensor and relief damper. Separate field accessories of
single enthalpy and dual enthalpy are also available. A
built-in barometric relief of 25% is provided.
