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 ver-
tical 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-coat-
ed prepainted steel capable of withstanding 500 hrs 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, 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.
Standard 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.
Short-Cycling protection for the compressor is incorporated
into our defrost control board ensuring a five minute delay (+/-2
minutes) before restarting compressor after shutdown for any
reason.
