The following are suggested specifications for the Zoneline
®
4100 Series Packaged Terminal Air Conditioner and the 6100
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 AHRI and cUL certified as to
capacity and efficiency and shall be GE 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-
temperature styrene 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 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
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
and 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);
SUGGESTED BID FORM SPECIFICATIONS
• 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 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 thermostat setting. Controls shall be covered by a
hinged door;
• Positive-closing, manually controlled, three-position fresh-air
vent capable of providing selection of fully open, partially open
or closed setting. Vent door is to be secured for shipping;
• Solid-state thermostat control to sense room temperature;
• 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 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 powered electrical circuit and unit shall provide ability for
owner to defeat the Freeze Sentinel operation;
• Heat Sentinel to automatically activate air conditioner
operation when the unit is in the STOP setting 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 Zoneline 6100 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, unit will lock out electric
resistance heat and operate on heat pump only.
