 include the Time Guard® II anti-short

cycle protection circuitry. If a non-corporate thermostat without
anti-short cycle protection is used the Time Guard II field in-
stalled anti-short cycle kit is recommended.

 

is designed to provide dependability. Liquid

filter dryers are used to promote clean, unrestricted operation.
Each unit leaves the factory with a full refrigerant charge. Refrig-
erant service connections make checking operating pressures
easier.

 

provide added reli-

ability for the compressor.

 

 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.

 

ensure a quiet indoor and outdoor environ-

ment with sound ratings as low as 72 dB. (See page 3.)

 

 provide easy single-panel accessibility

to serviceable components during maintenance and installation.
The unit base with integrated drain pan provides easy ground lev-
el installation with or without a mounting pad. Convenient rigging

holds are provided to manipulate the unit on the jobsite. A nesting
feature ensures a positive unit base 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.

 

 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.

 

 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.

 

provides safe and efficient

control of heating and simplifies trouble-shooting through its
built-in diagnostic function.

 

 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 fitting. 

 

 provides hail and vandalism protection.
