DESCRIPTION (CONTINUED)
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
build-up. The condensate pan conforms to ASHRAE 62-89
standards (Ventilation for Acceptable Indoor Air Quality).
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.
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 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 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 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 does not add 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.
CONDENSER COIL GRILLE - A multi-piece totally enclosed,
rigidly mounted condenser 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.
FAN SYSTEM - All models operate over a wide range of design
conditions with a 5 speed direct drive indoor blower motor.
These units easily match all types of applications and provide
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.
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. No final field mounting required.
EASY SERVICE ACCESS - A large, single panel covers the
electrical controls and 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 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 part houses.
