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 14 7 /
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).
1.03 DELIVERY, 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 and a random
continuous force of 1 g, 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% RH, non-
condensing, during shipment and storage, without
component failure.
D. Unit shall be stored and handled per manufacturer’s
recommendations.
Part 2 — Products
2.01 EQUIPMENT
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
