Specifications

The following are suggested specifications for the Zoneline 2500
Series Packaged Terminal Air Conditioner, the 3500 series
Packaged Terminal Heat Pump and the 5500 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 case, sub-base if specified, and outdoor
grille.
Units shall be listed by UL, and ARI and cUL certified as to
capacity and efficiency and shall be GE Zoneline
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 _______ volts, 60 Hz.,
single phase power.
Chassis. 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.
Chassis shall be 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
temperature styrene to resist corrosion and damage. 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. Cooling
shall be possible to outdoor temperature of 35°F. without
damage to the compressor. Airflow system consisting of one
permanently lubricated two-speed fan motor for the outdoor
fan and a separate permanently lubricated two-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 air flow 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.
Unit shall have a resistance heater to provide specified heat
output;
A fan cycle switch to permit continuous fan operation or fan
cycle operation, independently selectable for heating and
cooling operation;
A positive cooling condensate disposal system which meets
the test requirements of applicable A.R.I. Standard 310-93
(for Packaged Terminal Air Conditioners) and 380-93 (for
Packaged Terminal Heat Pump). (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 with enhancements
necessary 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 50°
off vertical air pattern with an alternate position to provide a
40° off vertical air pattern;
Easily accessible controls for selection of unit Operation and
® models or Thermostat setting. Controls shall be covered by a hinged

Electronic temperature limiting with seven independent
heating and cooling settings to limit maximum and
minimum temperatures without restricting movement of
thermostat control knob;
Freeze Sentinel
resistance heater and fan motor to warm and circulate
indoor air to help prevent damage due to freezing
temperatures. Freeze Sentinel
is connected to powered electrical circuit and unit shall
provide ability for owner to defeat the Freeze Sentinel
operation;
Compatible with 2 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;
Connections to interface with occupancy sensors;
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
Additional specifications for GE Zoneline 2500 Series Packaged
Terminal Air Conditioner with Dry Air 25
Unit shall be equipped with factory installed heat pipe
around evaporator coil to increase dehumidification by at
least 25% over other non-heat pipe Zoneline units. Unit
must be certified by ARI for capacity and dehumidification.
Heat pipe system must be separate from the sealed
refrigerating system of the unit.
TM to automatically activate the electric
TM shall operate as long as unit
® (NEC) and local codes.
