MECHANICAL SPECIFICATIONS
GENERAL DESCRIPTION
Units shall be High Efficiency factory-assembled, single pack-
aged, (DUS Electric Cooling/Gas Heat, DHC Electric Cooling/
Optional Electric Heat), designed for outdoor mounted instal-
lation. Units shall have minimum SEER ratings of 11.0. They
shall have built in field convertible duct connections for down
discharge supply/return or horizontal discharge supply/return,
and be available with factory installed options or field installed
accessories.
The units shall be factory wired, piped, charged with R-22
refrigerant and factory tested prior to shipment. All unit wiring
shall be both numbered and color coded. Enclosed in each
unit shall be a factory test log sheet consisting of the unit
tested pressures, temperatures and amps, as tested prior to
shipment.
All units shall be manufactured in a facility certified to ISO
9001 standards, and the cooling performance shall be rated
in accordance with DOE and ARI test procedures. Units shall
be UL listed and classified to ANSIZ21.47 standards and UL
1995/CAN/CSA No. 236-M90 conditions.
UNIT CABINET
1. Unit cabinet shall be constructed of G90 galvanized
steel, with exterior surfaces coated with a non-chalking,
powered paint finish, certified at 750 hours salt spray test
per ASTM-B117 standards.
2. Indoor blower section shall be insulated with up to 1”
thick insulation, coated on the air side. Aluminum foil
faced insulation shall be used in the furnace compart-
ment and be fastened with ridged fasteners to prevent
insulation from entering the air stream.
3. Cabinet panels shall be large size, easily removable for
servicing and maintenance.
4. Full perimeter base rails shall be provided to assure reli-
able transit of equipment, overhead rigging, fork truck
access and proper sealing on roof curb applications.
5. Disposable 1" filters shall be furnished and be accessible
through a removable access door, sealed air tight. Units
filter track shall be designed to accommodate either 1 or
2" filters.
6. Fan performance measuring ports shall be provided on
the outside of the cabinet to allow accurate air measure-
ments of evaporator fan performance without removing
panels or creating air by-pass of the coils.
7. Units vertical discharge and return duct configuration
shall be designed to fit between standard 24" O.C.
beams without modification to building structure, duct
work and base unit.
8. Condensate pan shall be internally sloped and conform
to ASHARE 62-89 self-draining standards. Condensate
connection shall be a minimum of 3/4" I.D. female and be
a ridged mount connection.
INDOOR (EVAPORATOR) FAN ASSEMBLY
1. Fan shall be direct drive, multi-speed, or a factory
installed belt drive, adjustable-pitch motor pulley option.
Job site selected (B.H.P.) brake horse power shall not
exceed the motors nameplate horse power rating, plus
the service factor. Units shall be designed not to operate
above service factor.
2. Fan wheel shall be double-inlet type with forward-curved
blades, dynamically balanced to operate smoothly
throughout the entire range of operation. Airflow design
shall be constant air volume.
3. Bearings shall be sealed and permanently lubricated for
longer life and no maintenance.
OUTDOOR (CONDENSER) FAN ASSEMBLY
1. The outdoor fan shall be of the direct-driven propeller
type, discharge air vertically, have aluminum blades riv-
eted to corrosion resistant steel spider bracket and shall
be dynamically balanced for smooth operation.
2. The outdoor fan motor shall be totally enclosed with per-
manently lubricated bearings and internally protected
against overload conditions.
REFRIGERANT COMPONENTS
1. Compressors:
a. Shall be fully hermetic type, direct drive, internally
protected with internal high-pressure relief and over
temperature protection. The hermetic motor shall be
suction gas cooled and have a voltage range of + or
- 10% of the unit nameplate voltage.
b. Shall have internal spring isolation and sound muf-
fling to minimize vibration and noise, and be exter-
nally isolated on a dedicated, independent
mounting.
2. Coils:
a. Evaporator and condenser coils shall have alumi-
num plate fins mechanically bonded to seamless
internally-enhanced copper tubes with all joints
brazed. Special Phenolic coating shall be available
as a factory option.
b. Evaporator and Condenser coils shall be of the
direct expansion, draw-through design.
3. Refrigerant Circuit and Refrigerant Safety Components
shall include:
