The following are suggested specifications for the 8500 Series
single packaged vertical air conditioners and heat pumps:
The contractor shall furnish single packaged vertical air
conditioners or heat pumps of the sizes and capacities
shown on the schedule or in the specifications. The units
shall be located as shown on the drawings and each shall
consist of a chassis, appropriately sized wall plenum,
outdoor grille, remote wall thermostat, support platform,
and closet access panel or door.
Units shall be listed by UL and cUL and shall be GE
Appliances Vertical Zoneline
®
models or equal. Unit
dimensions shall not exceed 23-1/8" x 23-1/8" x 32".
CHASSIS
The air conditioner chassis shall be the standard product
of the manufacturer and shall be shipped in protective
cartons to prevent damage. Cartons shall be appropriately
marked with factory wording sufficient to warn handlers
against dropping, improper stacking, upending or rolling.
The chassis shall be slide-in type, ready to operate
after installation.
The chassis shall be protected against the harmful effects
of airborne chemicals and saltwater corrosion.
The chassis shall have a hermetically sealed refrigerant
system with an external vibration isolated rotary
compressor. Indoor coils shall have copper tubing with
aluminum fins. Outdoor coils shall have copper tubing
with aluminum fins treated to resist the effects of airborne
chemicals and salt-water corrosion. All refrigerant coil fins
will have the necessary enhancements to achieve EER and
COP ratings of the unit. Refrigerant system metering shall
be done with capillaries.
Airflow system shall consist of one permanently lubricated
fan motor for the outdoor side and a separate permanently
lubricated three-speed motor for the indoor blower.
Outdoor fan shall be multi-blade axial-flow design made of
non-corrosive material. Indoor fan shall be blower type to
optimize airflow and minimize air noise. All motors on the
exterior side of the weather barrier shall be painted and
enclosed to reduce the effects of moisture and corrosion.
Units will have a positive cooling condensate disposal
system. The disposal system shall have a slinger ring on
the outdoor fan to dispose of condensate water and to
assist in cooling the outdoor coil.
Unit indoor and outdoor airflows must match the capacity
of the coils for efficient heat transfer and meet latent and
sensible heat requirements. Water blow-off shall not occur
on the indoor coil.
Unit shall have a sensor to prevent indoor coil freeze up.
WALL PLENUM
Wall Plenums shall be constructed of heavy gauge, zinc
coated, phosphated steel with a baked-on enamel finish.
Plenums shall be installed through the exterior wall where
shown on the plans and shall be of correct depth to allow
sealing to exterior and interior walls.
EXTERIOR GRILLES
Each unit shall be equipped with a standard exterior
grille that has been designed to allow operation in high
ambient conditions.
Special exterior grilles or custom louver sections supplied
by others will conform to minimum free area requirements
and shall be submitted to the manufacturer, if requested,
for feasibility and air flow characteristics.
ELECTRICAL
Units shall be designed to operate on 230/208 or 265-volts,
60 Hz, single-phase power.
Units shall have means of electrical connection listed by
Underwriters Laboratories and compatible with the units'
required voltage and ampacity in conformance with
National Electrical Code (NEC) and all local codes.
FEATURES
Unit must have a positive-closing fresh air ventilation
system with a concealed manual control.
Unit must be compatible with 2-wire Central Desk
Control systems.
Units must be compatible with Electronic Class-2 remote
wall thermostats.
Units must have available connections to interface with
occupancy sensors.
Using optional kit, unit shall have Electronic Temperature
Limiting with seven independent heating and cooling
settings to limit maximum and minimum room temperature
settings.
Using optional kit, unit shall be equipped with Freeze
Sentinel to automatically activate the electric heaters and
appropriate fan motors to warm and circulate indoor air
to prevent damage due to freezing temperatures. Freeze
Sentinel shall operate when unit is connected to a powered
electrical circuit and the unit shall have the ability to disable
this feature.
