GENERAL INFORMATION
Our units are designed to accommodate the everchanging installation requirements of today’s market.
All models 5 - 10 tons are shipped as factory-charged
unitized packages. Low prole design allows the unit to
be installed on the oor or suspended from the ceiling.
CPH models feature a ‘straight-through’ airow congu-
ration. Units are completely factory wired and piped.
These units are designed to allow easy passage through
doors, hallways and elevators. All unit components are
securely mounted inside the heavy gauge “Galvalume”
steel cabinet. All units are lined with 1/2” thick - 2 lb
density acoustical insulation to ensure the quietest op-
eration. All models are provided with medium- efciency
2” thick throwaway lters.
The 5 ton model has a single refrigerant circuit. The 8
and 10 ton models are dual compressor units with two independent compressor/ condenser circuits. Evaporator
coils are of copper tube and rippled aluminum plate n
construction. The high-efciency tube-in-tube condens-
ers feature a convoluted inner tube design for optimum
performance. Standard models feature a copper inner
tube surrounded by a steel outer tube, and carry a 400
psig working pressure rating. Multiple refrigerant circuit
models feature internally manifolded condensers (single
water in, water out connection).
Installation time is minimized with all models. When planning an installation consider power supply, thermostat,
condensate drain line, duct run, and service clearances.
A remote thermostat device is eld supplied and installed
to control the unit operation.
Service access doors are equipped with lifting handles,
and are located on both sides of the unit to allow easy
servicing of all components.
All units are equipped with centrifugal blowers combined
with variable pitch adjustable pulleys. Forward curved
double width, double inlet blowers are used for evaporator air movement. All models employ a draw-through
air ow arrangement. Large evaporator coil face areas
reduce noise levels, air pressure drops, and minimize
potential condensate blow-off. All blower wheels are
galvanized steel, with solid steel shafts supported in
permanently lubricated ball bearings. V-belts drive all
models and blower RPM can be adjusted through the
motor sheave.
High efciency Scroll compressors are used in all models, mounted on durable rubber isolators to reduce vibration and noise while operating. Each refrigerant circuit is
equipped with high pressure and low pressure switches.
All models are equipped with an adjustable thermal expansion valve (with external equalizer), one valve per
circuit. Each refrigerant circuit is also equipped with a
liquid line lter drier, sight glass/moisture indicator, and
service access ports. An electrically re-setable lock-out
relay will shut off the compressor in the event of pressure
switch trip during operation. Control circuit operates on
24V, and features an oversized transformer. Optional
anti-short circuit timers can be eld/factory installed.

PRE-INSTALLATION INSPECTION OF EQUIPMENT
All units are factory tested to ensure safe operation
and quality assembly. Units are packaged and sealed
on shipping skids and shipped in rst class condition.
Torn and broken packaging, scratched or dented panels should be reported to carrier immediately. Internal
inspection of all units should be performed prior to
installation . Remove all access doors and check for
visual defects that can occur during transport. Any problems found internally should be reported to carrier and
manufacturer immediately. Refrigerant circuit should be
checked to ensure no leaks have occurred during shipment. Install gauge set to high and low pressure ports
to conrm pressure has been maintained and no leaks
have occurred during shipment. Repair any damage
prior to installation to ensure safe operation.
Record any unit damage on the Bill of
Lading and report to carrier and factory
immediately. Shipping and handling
damages are not warranty items.
UNIT MOUNTING
The 5 through 10 ton models are shipped as a fully
assembled integral package. Units are not intended for
outdoor installation.
Units may be either hung, or oor mounted. If unit is to be
hung, use all mounting points indicated. The use of 1/2
in. diameter hanger rods is recommended. Ensure the
attachment points of the rods to the building structure are
sufcient to support the unit weight. In order to ensure
efcient condensate drainage, the unit may be pitched
towards the condensate drain outlet end of the unit. A
minimum of 4 in. clearance is required under the unit to
allow for trapping of the evaporator condensate drain.
Floor mounted units should be secured on a solid, level
pad. The use of isolating vibro-pads at several points
under the bottom mounting channels is recommended.
Ensure that provision is made for clearance to install a
trap on the condensate drain outlet.
RIGGING
PRIOR TO MOUNTING UNIT, CHECK
INDIVIDUAL UNIT WEIGHTS AND VERIFY LIFTING CAPACITY OF LIFTING
EQUIPMENT EXCEEDS WEIGHT OF
UNITS BY SAFE MARGINS. FAILURE TO
DO SO MAY RESULT IN UNIT DAMAGE,
PERSONAL INJURY OR EVEN DEATH.
DETERMINE THE ACTUAL CENTER OF
GRAVITY OF THE UNIT BY PERFORMING A TEST LIFT. LIFTING AN UNBALANCED UNIT CAN CAUSE PERSONAL
INJURY OR EVEN DEATH.
INSTALLATION
LOCK ALL ELECTRICAL POWER SUPPLY SWITCHES IN THE OFF POSITION
BEFORE INSTALLING THE UNIT. FAILURE TO DISCONNECT POWER SUPPLY
MAY RESULT IN ELECTRICAL SHOCK
OR EVEN DEATH.
Location - To ensure unit operates at maximum efciencies, choose a dry indoor area where the temperature
is controlled between 50ºF and 15ºF. Consideration
of surrounding areas should be taken when choosing
a location to install the unit. Common vibration and
sound levels associated with commercial equipment
may be objectionable to people or equipment. Install
thermostats, air supplies and returns so that each unit
will operate only on individual unit control.
