Easy to service cabinets provide easy single-panel accessibility
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 rooftop easy.
Louvered Grille provides hail and vandalism protection for the
coil.
Downflow operation is easily provided in the field to allow vertical
ductwork connections. The basepan utilizes knockout style seals
on the bottom openings to ensure a positive seal in the horizontal
airflow mode.
Cabinets are constructed of heavy-duty, phosphated, zinc-coated
prepainted steel capable of withstanding 500 hours of salt spray.
Interior surfaces of the evaporator and electric heater
compartments 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 No. 62P.) The sloped drain pan
minimizes standing water in the drain, which is provided with an
external drain.
Standard metal duct covers with insulation come with the unit
and cover the horizontal duct openings. These can be left in place
if the unit is converted to downflow.
