The following are suggested specifications for
the Zoneline
®
AZ45 Series Packaged Terminal Air
Conditioner and the AZ65 Series Packaged Terminal
Heat Pump.
The contractor will furnish packaged terminal air
conditioners of the sizes and capacities shown on the
schedule and in the specifications. The units shall be
located as shown on the drawings and each shall consist
of a chassis, room cabinet, wall sleeve, sub-base if
specified, and outdoor grille.
Units shall be listed by UL, and AHRI and cUL certified
as to capacity and efficiency and shall be GE Appliances
Zoneline
®
models or equal. Unit dimensions shall not
exceed 42-1/8" wide and 16-1/4" high with room cabinet
in place.
Units shall be designed to operate on (208) (230) (265)
volts, 60 Hz, single-phase power.
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 at the factory with wording
sufficient to warn handlers against improper stacking,
up-ending, rolling or dropping. The chassis shall be the
slide-in type, ready to operate after installation.
Each shall consist of the following sections
and components:
• Each unit shall have a matching, easily removable,
textured finish, wrap-around room cabinet molded of
high-impact Polystyrene to resist corrosion and damage.
The room cabinet shall have slide-out washable filters
accessible without requiring removal of room cabinet
from chassis;
• Hermetically sealed refrigerant system with external
vibration isolated rotary-type compressor, condenser
and evaporator coils and capillary refrigerant control.
Airflow system consisting of one permanently lubricated
variable-speed fan motor for the outdoor fan and a
separate permanently lubricated variable-speed fan
motor for the indoor fan. Outdoor fan shall be multi-
blade axial-flow design made of non-corrosive material.
Indoor fan shall be of a design to optimize airflow and
operating sound. All motors on the exterior side of the
weather barrier shall be of an enclosed design to reduce
the effects of moisture and corrosion;
• Line-cord connected units shall require a line-cord
power connection kit with integral Leakage Current
Detection Interruption device or (Arc Fault Current
Interrupter) as required by National Electrical Code
®
(NEC) and Underwriters' Laboratories. The unit
shall have a universal resistance heater with output
determined by connection to the power source with
the appropriate power connection kit to provide
specified heat output;
• A fan-cycle option to permit continuous fan operation
or fan cycle operation, independently selectable for
heating and cooling operation;
• Fan-only operation in either high or low fan speed
selectable by room occupant;
• A positive cooling condensate disposal system which
meets the test requirements of applicable AHRI
Standard 310 (for packaged terminal air conditioners) and
380 (for packaged terminal heat pumps) (80°F dry bulb,
75°F wet bulb, 80% relative humidity);
• Condenser and evaporator coils to be constructed
of copper tubing and aluminum plate fins designed
to achieve EER and COP rating of the unit;
• Indoor and outdoor airflows that match the capacity
of the coils for efficient heat transfer. Water blow-off
shall not occur on the indoor coil;
• Adjustable indoor discharge air louvers that provide
a 45° off horizontal air pattern with an alternate position
to provide a 65° off horizontal air pattern;
• Easily accessible controls for selection of unit operation
and thermostat setting.
• Controls shall automatically dim to not disturb the guest;
• Positive-closing, manually controlled, multi-position
fresh-air vent capable of providing selection anywhere
from fully open to fully closed. Vent door is to be secured
for shipping;
• Integrated circuit and software to sense and control room
temperature;
• Electronic temperature limiting with seven independent
heating and cooling settings to limit maximum and
minimum temperatures.
• Freeze Sentinel to automatically activate the electric
resistance heater and fan motor to warm and circulate
indoor air to help prevent damage due to freezing
temperatures. Freeze Sentinel shall operate as long as
unit is connected to a powered electrical circuit and
unit shall provide ability for owner to defeat the Freeze
Sentinel operation;
• Heat Sentinel to automatically activate air conditioner
operation as long as unit is connected to a powered
electrical circuit (even if the unit is in the off mode when
the room temperature warms to 85ºF and turns air
conditioner operation off when the room temperature
cools to 80°F, if selected by owner;
• Compatible with two-wire Central Desk Control systems;
• Remote thermostat compatibility with Class 2 remote
thermostat;
• Connections to interface with a transfer fan to move
air into another room;
Unit shall have means of electrical connection listed by
Underwriters' Laboratories and compatible with the unit’s
required voltage and ampacity in conformance with
National Electrical Code and local codes.
Additional specifications for GE Appliances Zoneline
AZ65 Series Packaged Terminal Heat Pumps:
Heat pump units shall provide operation that will either: A)
automatically phase in electric resistance heat, if outdoor
temperature is below 46°F, if heat pump alone is unable
to maintain room temperature; or B) use partial electric
resistance heat simultaneous with heat pump operation any
time the outdoor temperature is below 46°F. Selection of
A or B operation is made by means of a selector concealed
from room occupant. In either A or B operation, the unit will
switch to full resistance heat if room temperature continues
to decline or the outdoor temperature falls below 25°F.
If the outdoor temperature is above 46°F (and below 86°F),
unit will lock out electric resistance heat and operate on
heat pump only.
