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.
Low sound ratings ensure a quiet indoor and outdoor environment with
sound ratings as low as 69dBA.
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 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.
Standard horizontal metal duct covers 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 heavy duty, 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 Air Conditioning Engineers 62.2.) The sloped drain
pan minimizes standing water in the drain. An external drain is provided.
