Insulated Polymer Wall Sleeve:Wall sleeve shall provide excellent thermal insula-tion, be textured to hide scratches and preventshine, will have superior outdoor noise absorptionand shall be corrosion free for the life of the prod-uct. The Wall Sleeve must have dimensions of42 in. width x 16 in. height x 147/8 in. depth and beshipped with a rear weather barrier installed.B. Wall Sleeve Molding:Molding shall trim the wall sleeve to the existingwall, to hide wall imperfections and irregularities inthe wall opening.C. Outdoor Polymer Louvered Grille:Outdoor grille shall resist corrosion, breakage andmatch the color specified on drawing schedule andspecifications.D. Subbase:Subbase will support the wall sleeve when itextends into the room more than 4 inches. Subbasemust come from the factory pre-assembled, with abuilt in receptacle (size as specified on drawingschedule and specifications) or with factory-installed hardwire, pre-sized for an exact fit to theunit.1.02 QUALITY ASSURANCESystem shall be approved and certified by UL andUL, Canada. Chassis capacity and efficiency perfor-mance shall be certified in accordance with ARIstandard 310/380. Chassis shall meet ASHRAEStandard 90.1 for minimum energy efficiency.Chassis shall meet the New York City Department ofBuilding, Material and Equipment acceptance require-ment (MEA).1.03 DELIVERY, STORAGE, AND HANDLINGA. The packaging of the chassis shall be sufficient toprotect the chassis from damage during shipmentvia an enclosed truck. Chassis must also be able towithstand an impact force of 10 g’s and a randomcontinuous force of 1g, during shipping.B. Chassis, wall sleeves, and grilles shall be shipped inseparate cartons. Universal handling instructionsshall be defined and visible on the carton, fromfront, 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’srecommendations.Part 2 — Products2.01 EQUIPMENTA. General:Factory-assembled, single-piece heating and/orcooling unit. Contained within the unit enclosureshall be compressor, coils, fans and fan motor, heat-ing means, controls, all wiring and piping, and afull refrigerant charge (R-22).Packaged Terminal Air Conditioners shall be of thesizes 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 toinstall and operate. Just slide the chassis into a wallsleeve, plug it into an outlet, and operate afterinstallation. The chassis dimensions shall notexceed 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 permaximum load criteria of ARI Standard 310/380.2. Electrical:Chassis shall be equipped with a 58 in. powercord for 208/230 v models or a 15 in. powercord for 265 v models. The chassis currentdraw shall be specified on the chassis name-plate and match electrical requirements speci-fied on the Contract drawing schedule andspecifications. The power cord plug configura-tion shall conform to NEMA standards and therating shall support the current draw of theelectric resistance heater.For 265 v installations, UL codes require theuse of an electrical equipped subbase forpower cord usage or hardwire conduit for non-corded installations.C. Airflow System:The airflow system shall consist of one permanentsplit-capacitor, direct-drive permanently lubri-cated, two-speed fan motor for the indoor and out-door fans. The outdoor fan shall be a dynamicallybalanced, corrosion-resistant polymer multi-bladeGUIDE SPECIFICATIONS
