High and Low Pressure Switches provide added reliability for the
compressor.
Indoor and Outdoor coils are computer- -designed for optimum
heat transfer and efficiency. The indoor coil is fabricated from
copper tube and aluminum fins and is located inside the unit for
protection against damage. The outdoor coil is internally mounted
on the top tier of the unit. Copper fin coils and pre- -coated fin coils
are available from the factory by special order. These coils are
recommended in applications where aluminum fins are likely to be
damaged due to corrosion. They are ideal for seacoast applications.
Low sound ratings ensure a quiet indoor and outdoor
environment with sound ratings as low as 75dBA.
Easy to service cabinets provide easy 3- -panel accessibility to
serviceable components during maintenance and installation. The
basepan with integrated drain pan provides easy ground level
installation with a mounting pad. A nesting feature ensures a
positive basepan to roof curb seal when the unit is roof mounted. A
convenient 3/4- -in. (19.05 mm) wide perimeter flange makes frame
mounting on a rooftop easy.

Horizontal metal duct covers are standard with insulation come
with the unit and cover the horizontal duct openings. These can be
left in place if the units are converted to downflow.
Integrated Gas Control (IGC) board provides safe and efficient
control of heating and simplifies trouble- -shooting through its
built- -in diagnostic function.
Cabinets are constructed of heavyduty, phosphated, zinc- -coated
prepainted steel capable of withstanding 500 hours in salt spray.
Interior surfaces of the evaporator/heat exchanger compartment are
insulated with cleanable semi- -rigid insulation board, which keeps
the conditioned air from being affected by the outdoor ambient
temperature and provides improved indoor air quality. (Conforms
to American Society of Heating, Refrigeration and
Conditioning Engineers 62.2.) The sloped drain pan minimizes
standing water in the drain. An external drain is provided.
