Performance Specifications (
cont.
)
D.
Refrigeration system is constructed of a vibration
isolated, hermetically sealed, thermally protected
rotary compressor.
E.
Compressors have protection to prevent operation
below 35 °F. Capillary tube refrigerant control sized
according to the cooling BTU ratings.
F.
Indoor freeze protection preventing room from go-
ing below 50 °F, is standard.
G.
Refrigerant metering device shall be a capillary tube
with compressor freeze protection.
H.
Air moving system is a dual motor system, which
consists of a multi thermally-protected PSC evapora-
tor motor employing dual forward curved centrifugal
blower wheels, providing between 280 and 460 CFM
depending on unit capacity, along with a separate
thermally-protected PSC condenser motor employ-
ing an aluminum propeller-type fan blade providing
600 CFM. A blow-through condenser airflow design
for increased efficiencies.
I.
Tubular heat exchanger with integral flame spreaders
constructed of welded commercial quality stainless
steel located within the indoor air stream as not to be
visible or accessible through the indoor discharge air
grill or return air area of the unit. Sealed combustion
air blower, combustion chamber and heat exchanger,
which uses only outdoor air in the combustion pro-
cess. Electronically controlled combination pressure
regulator and gas valve, pilotless hot ceramic, flame
sensing ignition system, which is thermostatically
controlled by the indoor room temperature in the
heating cycle.
J.
Unit mounted electronic controls providing OFF, HI
FAN, LO FAN, HI HEAT, LO HEAT, HI COOL, and
LO COOL settings.
K.
All chassis parts shall be constructed of commercial
grade galvanized steel. The firewall base pan shall
be constructed of galvanised steel with a powdered-
coated paint for maximum corrosion resistance.
E.
Condensate Drain
This universal drain kit shall be used internally or
externally to route excess condensate to a drainage
system. It can be field-installed on any Islandaire
wall sleeve. The drain kit shall be attached to the
exterior right or left side of the wall sleeve for exter-
nal draining or may be mounted to the bottom of the
wall sleeve for internal draining.
F.
Lateral Duct
The kit shall include an adapter plenum, extension
duct, wall register and wall molding. The lateral
duct system allows one system to heat or cool two
adjacent rooms, by directing up to 30% of the airflow
to the adjacent room. See page 33 for detailed
specification.
G.
Front Desk Control
Unit controls shall provide front desk control on all
units, allowing individual units to be turned on and
off from a remote location or by a motion sensing
device. Front desk controls shall interface to most
energy management systems.
5.0 GENERAL REqUIREMENTS
A.
Provide a packaged terminal electric air condition-
ing/natural gas heating unit listed in the following
specifications.
B.
Each unit shall consist of a chassis,wall sleeve, ex-
terior grille, and finished inside wrap around room
cabinet. Units shall be CSA approved, AGA Design
Certified, and CGA Design Certified. Units shall be
manufactured by Islandaire Inc., or equivalent.
C.
Shall be a slide-in, plug-in chassis with self-contained
refrigerant system consisting of a vibration-isolated
compressor, separate condenser and evaporator fan
motors, condenser fan and coil, evaporator dual
blower and coil, copper refrigerant tubing, operating
controls and positive condensate removal system.
Chassis shall be constructed of heavy gauge com-
mercial quality G-60 galvanized steel with baked-on
powder coat painted base pan/firewall and stainless
steel compressor studs for unsurpassed corrosion
resistance.
