DESCRIPTION
These packaged heat pumps are designed for outdoor installation. Only utility and duct connections are required at the point
of installation.
such as, system pressure, motor currents, air velocity and temperature unit vibration are monitored and recorded by the system
to insure unit performance.
Field-installed electric heater accessories are available to
provide electric heat, if required.
Equal size, side supply and return duct connections allow easy
hook-up of ducts to match low crawl spaces without transition
pieces.
STANDARD FEATURES / BENEFITS
OPERATING EFFICIENCY - All units provide high operating efficiencies of 12 SEER or greater, 3.0 COP or greater, and up to 7.2
HSPF. All efficiencies exceed legislated minimum levels.
ON SITE FLEXIBILITY - All model sizes share a common,
compact design cabinet with a single footprint. The installer
has the flexibility of setting one curb or pad and placing the
proper tonnage unit after the internal load has been determined. Field convertible duct connections, from side shot to
down shot, allows the installer greater flexibility and the need to
carry less inventory.
UTILITY CONNECTIONS MADE EASY - Electrical 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. They are ready 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.
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 models are under 500
pounds.
CONDENSATE PAN - A non-corrosive, long-lasting, water-tight
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).
All units are completely wired, charged with R-22 and tested prior
to shipment. Unique test stations, are used to insure product quality. Refrigerant charge, and component part numbers are verified
via computers at manufacturing point. Vital run test statistics,
CONDENSATE DRAIN - The heavy duty, ! " inch NPTI copper
connection is more tolerable during installation and is more durable over time. The connection is rigidly mounted to assure
proper fit and leak tight seal.
FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE

STANDARD FEATURES and BENEFITS - continued
DURABLE FINISH - With a heavy duty cabinet made of
powder-painted, galvanized steel, the neutral color blends into
surrounding areas. The powered paint provides a better paint
to steel bond, which resists corrosion and rust creep. The special primer formulas and glossy earth tone finish insure less
fading when exposed to sunlight and offers a more attractive on
site appearance. This paint finish exceeds ASTM-B117 standards for 1000 hour salt spray rating, the highest in the industry.
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. Rigging holes are, provided also so that an overhead
crane can be used to place the unit on a roof. On applications
when 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 2-3/8 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 reduces insulation fibers into
conditioned area.
TOP DISCHARGE - The top discharge condenser fan does not
disrupt neighboring areas and does not 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.
OUTDOOR COIL GRILLE - A multi-piece totally enclosed, rigidly mounted outdoor coil grille provides protection from objects and personnel after installation. It also provides
protection during transit and installation.
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 either a 3-speed direct-drive fan motor or an
(E.C.M.) electronically commutated motor that automatically adjusts the blower speed to meet a wide range of static requirements. These units easily match all types of applications and
provides greater on site flexibility to match comfort requirements.
SIMPLE CONTROL CIRCUIT - A low voltage printed circuit
board contains a low voltage terminal strip. The electrical control box is not located in the compressor compartment. All wiring internal to the unit is color/number coded.
CONTROLS - Reliable time-temperature defrost control provides defrost, including field selectable time periods between
cycles (30, 60 and 90 minutes); factory set at 30 minutes. Defrost control also provides an “X” terminal to provide a 24 volt
signal for room thermostat “LED” indication of unit lockout,
plus, built in 5 minute anti-short cycle protection.
2
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 protects the
compressor, if undesirable operating conditions occur.
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. 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.
EASY SERVICE ACCESS - A large, single hinged panel covers the electrical controls and makes servicing easy. The
blower compartment has an additional large panel with a builtin 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 has no need to carry
an inventory of unique parts or needs special training to replace any of the components parts for these units. All are easily
obtained from Source 1 or other major part houses.
FIELD-INSTALLED ACCESSORIES

NOTE: 1. Deduct these resistance values from the available external static pressure shown in the respective Blower Performance Table.
2. The pressure thru the economizer is greater for 100% outdoor air then for 100% return air. If the resistance of the return air duct system is less then 0.25 IWG, the unit will deliver
less CFM during full economizer operation.
