GENERAL MECHANICAL SPECIFICATIONS
GENERAL - All 2 to 10 ton models ship with a full refrigerant
charge. The 12 and 15 ton models are shipped as separate
evaporator and condensing unit modules (nitrogen holding
charge only). The 4 through 10 ton units include refrigeration
line shut-off valves to allow the units to be field split. All pack-
ages/models are designed for suspended mounting via inte-
gral structural channels.

ages/models are designed for suspended mounting via inte-

CABINET - All cabinets are completely constructed of 18
Gauge corrosion resistant "Galvalume" coated steel. The
entire unit interior (both evaporator and condensing section)
is insulated with 1/2" thick 2 LB density insulation. Service
panels are equipped with 1/2" thick 2 lb. density insulation.
Service panels are equipped with lifting handles for ease of
removal and handling.

COMPRESSORS - All models utilize "Scroll" type hermetic
compressors. Compressors are mounted on rubber isolators
to minimize vibration transmission. Internal overload protec-
tion is provided. External high pressure and low pressure cut-
out switches are included in each compressor control circuit.
Crankcase heaters are standard on all models.

REFRIGERANT CIRCUIT - The 2 to 5 tons units use a single
refrigeration circuit. The 8 to 15 ton units feature two indepen-
dent refrigeration circuits. Each circuit includes an adjustable
thermal expansion valve (with external equalizer), liquid line
filter drier, sight glass/moisture indicator, and service gauge
ports.

EVAPORATOR AND CONDENSER COILS - The evaporator
and condenser coils are constructed of internally enhanced
and condenser coils are constructed of internally enhanced
copper tubes mechanically bonded to rippled aluminum plate
fins. Both coils are employed in a draw-through configuration.
Large evaporator coil face area minimizes potential water
blow-off (max face velocity is 550 fpm at rated airflow).

INDOOR/OUTDOOR FANS - Forward curved, double inlet
and double width centrifugal blowers are used for both evap-
orator and condenser air movement. blow wheels are fabri-
cated of galvanized steel. Blowers employ solid steel shafts,
supported in permanently lubricated ball bearing. All blow-
ers are belt driven in permanently lubricated ball bearing. All
blowers are belt driven. Variable-pitch motor sheaves allow
for field adjustment of blower rpm.

ELECTRICAL/CONTROLS - All units are completely factory
wired with all necessary controls. Manual reset protection is
provided on both evaporator and condenser motors. A man-
ual reset circuit is also provided on each compressor control
circuit in the event of high/low pressure cutout. A 24 volt con-
trol circuit with oversize transformer, is provided for field con-
nection.

efficiency throwaway filters factory installed. Filter rack is
internal to the cabinet.
