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 certified to UL 1995/CAN/CSA C22.2 No. 236 standard.

UNIT CABINET

1.Unit cabinet shall be constructed of galvanized steel, with exterior surfaces coated with a non-chalking, powered paint finish, certified at 1000 hours salt spray test per ASTM-B117 standards.

2.The unit top shall be a single piece “Water Shed” design, with drip edges and no-seam corners to provide optimum water integrity.

3.Unit shall have a rigidly mounted condenser coil guard to provide protection from objects and personnel after installation.

4.Indoor blower section shall be insulated with up to 3/4” thick, aluminum, foil faced insulation, fastened to prevent insulation from entering the air stream.

5.Cabinet panels shall be “large” size, easily removable for servicing and maintenance, with built-in lift handles.

6.Unit shall be built on a formed, “Super-Structure” design base pan, with embossments at critical points to add strength, rigidity and aid in minimizing sound.

7.Full perimeter base rails shall be provided to assure reliable transit of equipment, overhead rigging, fork truck access and proper sealing on roof curb applications. Base rails shall be removable, when required, to lower unit height.

8.Filters shall be furnished and be accessible through a removable access door, sealed air tight. (Single phase models - accessory kit available. Three phase models - standard from factory.)

9.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.

10.Condensate pan shall be internally sloped and conform to ASHARE 62-89 self-draining standards, with ¾” NPTI copper, ridged mount connection.

INDOOR (EVAPORATOR) FAN ASSEMBLY

1.The ACP fan motor shall be direct drive, 5 speed design.

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.

4.Fan assembly shall be “Slip Track” (slide-out) design for easy removal and cleaning.

OUTDOOR (CONDENSER) FAN ASSEMBLY

1.The outdoor fan shall be of the direct-driven propeller type, discharge air vertically, have aluminum blades riveted to corrosion resistant steel spider bracket and shall be statically balanced for smooth operation.

2.The outdoor fan motor shall be totally enclosed with permanently lubricated bearings and internally protected against overload conditions.

REFRIGERANT COMPONENTS

1.Compressors:

a.Shall be fully hermetic reciprocating 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 isolation and sound muffling to minimize vibration and noise, and be externally isolated on a dedicated, independent mounting.

2.Coils:

a.Evaporator and condenser coils shall have aluminum plate fins mechanically bonded to seamless internally- enhanced copper tubes with all joints brazed.

bEvaporator and Condenser coils shall be of the direct expansion, draw-thru design.

3.Refrigerant Circuit and Refrigerant Safety Components shall include:

a.Independent fixed-orifice or balanced port bi-flow TXV expansion devices.

b.Filter/strainer to eliminate any foreign matter.

c.Accessible service gage connections on both suction and discharge lines to charge, evacuate, and measure refrigerant pressure during any necessary servicing or troubleshooting, without losing charge and without disrupting condenser or evaporator air flow.

dThe refrigeration system shall provide at least 10° F of liquid sub-cooling at design conditions.

4.Unit Controls:
