Suggested Bid Form Specifications

The following are suggested specifications for the Zoneline® 2800 Series Packaged Terminal Air Conditioner, the 3800 Series Packaged Terminal Heat Pump and the 5800 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® 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. 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 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 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 switch 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 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 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;

•Air discharge area accessible for cleaning without tools when room front is removed for 2800 and 3800 Series;

•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;

•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® (NEC) and local codes.
