HIGH AND LOW PRESSURE SWITCHES
Evaporator and condenser coils are computer-designed for
optimum heat transfer and cooling efficiency. The evaporator
coil is fabricated from copper tube and aluminum fins and is lo-
cated inside the unit for protection against damage. The con-
denser 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 appli-
cations 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 environ-
ment with sound ratings as low as 7.2 bels. (See page 3.)
Easy to service cabinets provide easy single-panel acces-
sibility to serviceable components during maintenance and
installation. The basepan with integrated drain pan provides
easy ground level installation with or without a mounting pad.
Convenient handholds are provided to manipulate the unit
on the jobsite. A nesting feature ensures a positive basepan
to roof curb seal when the unit is roof mounted. A convenient
3/4-in. wide perimeter flange makes frame mounting on a roof-
top easy.
Downflow operation is easily provided in the field to allow ver-
tical ductwork connections. The basepan utilizes knockout style
seals on the bottom openings to ensure a positive seal in the
horizontal airflow mode.
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, Refriger-
ation and Air Conditioning Engineers No. 62P.) The sloped drain
pan minimizes standing water in the drain, which is provided with
an external drain.
Louvered Grille provides hail and vandalism protection.
