1.01 SYSTEM DESCRIPTION

Single piece, thru-the-wall electrically controlled unit using hermetic rotary compressor for cooling and heat pump or electric resistance heat, as shown on the con- tract drawings.

A.Insulated Polymer Wall Sleeve:

Wall sleeve shall provide excellent thermal insula- tion, be textured to hide scratches and prevent shine, will have superior outdoor noise absorption and shall be corrosion free for the life of the prod- uct. The Wall Sleeve must have dimensions of

42 in. width x 16 in. height x 147/8 in. depth and be shipped with a rear weather barrier installed.

B.Wall Sleeve Molding:

Molding shall trim the wall sleeve to the existing wall, to hide wall imperfections and irregularities in the wall opening.

C.Outdoor Polymer Louvered Grille:

Outdoor grille shall resist corrosion, breakage and match the color specified on drawing schedule and specifications.

D.Subbase:

Subbase will support the wall sleeve when it extends into the room more than 4 inches. Subbase must come from the factory pre-assembled, with a built in receptacle (size as specified on drawing schedule and specifications) or with factory- installed hardwire, pre-sized for an exact fit to the unit.

1.02 QUALITY ASSURANCE

System shall be approved and certified by UL and UL, Canada. Chassis capacity and efficiency perfor- mance shall be certified in accordance with ARI standard 310/380. Chassis shall meet ASHRAE Standard 90.1 for minimum energy efficiency.

Chassis shall meet the New York City Department of Building, Material and Equipment acceptance require- ment (MEA).

1.03DELIVERY, STORAGE, AND HANDLING

A.The packaging of the chassis shall be sufficient to protect the chassis from damage during shipment via an enclosed truck. Chassis must also be able to withstand an impact force of 10 g’s and a random continuous force of 1g, during shipping.

B.Chassis, wall sleeves, and grilles shall be shipped in separate cartons. Universal handling instructions shall be defined and visible on the carton, from front, back and sides.

C.Chassis shall be capable of withstanding tempera- tures from –40 F to 155 F, at 5 to 95 percent RH, non-condensing, during shipment and storage, without component failure.

D.Unit shall be stored and handled per manufacturer’s recommendations.

2.01EQUIPMENT

A.General:

Factory-assembled, single-piece heating and/or cooling unit. Contained within the unit enclosure shall be compressor, coils, fans and fan motor, heat- ing means, controls, all wiring and piping, and a full refrigerant charge (R-22).

Packaged Terminal Air Conditioners shall be of the sizes and capacities as shown on the contract draw- ing schedule and in the specifications.

B.Chassis:

The chassis shall be a factory-assembled, single- piece heating and/or cooling unit, that is simple to install and operate. Just slide the chassis into a wall sleeve, plug it into an outlet, and operate after installation. The chassis dimensions shall not exceed 42 in. wide and 16 in. high with room cabi- net in place. The chassis shall consist of the follow- ing functional sections and components:

1.Operating Characteristics:

Chassis shall be capable of starting and run- ning at 115 F ambient outdoor temperature per maximum load criteria of ARI Standard 310/ 380.

2.Electrical:

Chassis shall be equipped with a 58 in. power cord for 208/230 v models or a 15 in. power cord for 265 v models. The chassis current draw shall be specified on the chassis name- plate and match electrical requirements speci- fied on the Contract drawing schedule and specifications. The power cord plug configura- tion shall conform to NEMA standards and the rating shall support the current draw of the electric resistance heater.

For 265 v installations, UL codes require the use of an electrical equipped subbase for power cord usage or hardwire conduit for non- corded installations.

C.Airflow System:

The airflow system shall consist of one permanent split-capacitor, direct-drive permanently lubri- cated, two-speed fan motor for the indoor and out- door fans. The outdoor fan shall be a dynamically balanced, corrosion-resistant polymer multi-blade
