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.
