CONDENSATE PAN
A non-corrosive, long-lasting, water-tight pan is posi-
tioned 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 sur-
rounding 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.
FULL PERIMETER BASE RAILS
The easily removable base rails provide a solid founda-
tion for the entire unit and protects the unit during ship-
ment. 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 appli-
cations when the unit is placed on a pad, the base will
keep the unit off the pad to deter corrosion. On applica-
tions where height is limited, the 2-3/8 inch high base
rails may be removed on location.
MORE ATTRACTIVE APPEARANCE
A single piece ìWater Shedî 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 cabi-
net 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 sur-
rounding the unit. The warm air from the top mounted
fan is blown up away from the structure and any land-
scaping. 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 person-
nel 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 ìSuper-Structureî 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 condi-
tions with 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 volt-
age 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 demand defrost control provides defrost.
Defrost control also provides an ìXî terminal to provide
a 24 volt signal for room thermostat ìLEDî indication of
unit lockout, plus, built in 5 minute anti-short cycle pro-
tection.
