and evacuated prior to final charg-
ing. Automated run testing allows
accurate undisputed tests and mea-
surements which are second to none
in the industry.
Durable, dependable
components
Scroll compressors are designed
for high efficiency. Each scroll
compressor is hermetically sealed
against contamination to help pro-
mote longer life and dependable opera-
tion. Vibration isolation provides
quiet operation. Scroll compressors
are standard on all units. Compressors
have internal high-pressure and over-
current protection.
Direct-drive multispeed, PSC
(permanent split capacitor)
blower motor is standard on sizes
024-042 and variable speed (inte-
grated control motor) is standard on
sizes 048 and 060.
Direct-drive, PSC outdoor-fan
motors are designed to help reduce
energy consumption and provide
for cooling operation down to 40 F.
Refrigerant system is designed to
provide dependability. Liquid refrig-
erant strainers are used to promote
clean, unrestricted operation. Loss-
of-charge switch is standard on all
units. Each unit leaves the factory with
a full refrigerant charge. Refrigerant
service connections make check-
ing operating pressures easier.
A fixed metering device controls
refrigerant flow precisely.
Solid-state Time Guard circuit
protects the compressor by preventing
potentially damaging too-rapid cy-
cling. Time Guard circuit is standard
on all units.
Indoor and outdoor coils are
computer-designed for optimum heat
transfer and cooling efficiency. Out-
door coil is fabricated of copper tube
and aluminum fins and is located
inside the unit to protect against dam-
age and ensure long life and reliable
operation. The outdoor coil is pro-
tected by a coil grille.
Copper fin coils are also available
by special order. These coils are recom-
mended in applications where alumi-
num fins are likely to be destroyed
due to corrosion. They are ideal for
seacoast applications.

Chronotemp™ defrost system pro-
vides time/temperature-based defrost
cycles to maintain unit efficiency.
This highly reliable system checks for
coil icing conditions at preset time
intervals and initiates a defrost cycle
only if required. The defrost cycle
ends as soon as defrosting is
accomplished.
The Chronotemp defrost board
may be configured for 30, 50, or
90 minutes.
Indoor air quality is improved
with cleanable foil-faced insulation.
Interior surfaces of the indoor com-
partment are insulated with cleanable
foil-faced insulation to help keep
the conditioned air from being affected
by the outdoor ambient temperature
and to provide improved air qual-
ity. Unit sloped condensate and drain
pan conform to American Society
of Heating, Refrigeration, and Air
Conditioning Engineers (ASHRAE)
No. 62P. Sloped condensate pan
is made of non-corrosive material.
Low sound ratings ensure a quiet
indoor and outdoor environment with
sound ratings as low as 7.8 bels.

Easy to service cabinets provide
easy accessibility to serviceable com-
ponents during installation and
maintenance. Rounded corners are
an important safety feature. A high-
quality finish ensures an attractive
appearance.
The cabinet is constructed of gal-
vanized steel, bonderized and coated
with a prepainted baked enamel
finish. The paint finish is a non-
calking type, and is capable of with-
standing Federal Test Method Stand-
ard No. 141 (Method 6061) 500-hour
salt spray test. In addition, all inter-
nal cabinet panels are primed, allow-
ing the entire unit to have a longer life
and more attractive appearance.
Compact size enables the unit to be
located where space is limited.
The standard control system is
readily adaptable to all conventional
and programmable thermostats. In
addition, units are suitable for integra-
tion into building monitor control
systems if required.
