Features and Benefits

Standard Features
• Operating Efficiency - All air conditioners provide
operating efficiencies of 13 to 15 SEER. 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, 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).
• Condensate Drain - The heavy duty, 3/4 inch NPTI copper
connection is more durable over time. The connection is
rigidly mounted to assure proper fit and leak tight seal.
• Durable Finish - With a heavy duty cabinet made of
powder-painted, galvanized steel the neutral color blends
into surrounding areas. The powdered paint provides a
better paint to steel bond, which resists corrosion and rust
creep. The special primer formulas and glossy finish
insures less fading when exposed to sunlight and offers a
more attractive on site appearance. This paint finish
meets ASTM-B117 standards for 1000 hours 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, 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 DEZ models utilize a
decorative "Wire-Form" coil guard to provide impact
protection against large objects. All other models utilize a
stamped "Louvered" design which provides superior
