DESCRIPTION
These packaged heat pumps are designed for outdoor installation. Only utility and duct connections are required at the
point of installation.
tistics such as system pressure, motor currents, air velocity and
temperature and 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 allows
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 10 SEER or greater, 3.0 COP or greater and up to
7.0 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 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 and needs to carry 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 models are well
under 500 pounds.
All units are completely wired, charged with R-22 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 manufacturing point. Vital run test sta-
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 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, water-tight
pan is positioned below the evaporator coil to collect and drain all
condensate. Less collection of stagnate condensate will buildup. The condensate pan conforms to ASHRAE 62-89 standards
(Ventilation for Acceptable Indoor Air Quality).
CONDENSATE DRAIN - The heavy duty, 3 4 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 750 hours salt spray rating, the highest in the industry.
FAN SYSTEM - All models operate over a wide range of design
conditions with a 3-speed direct-drive fan motor. These units
easily match all types of applications and provides greater on
site flexibility to match comfort requirement.
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 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.
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.
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 personal after installation and 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.
2
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.
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.
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 removed for cleaning 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.

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.
