4 FEATURES All units are self-contained and assembled on full perimeter base rails with forklift holes on three sides and holes for overhead rigging. Every unit is completely piped, wired, charged and tested at the factory to simplify the field installation and to provide years of dependable operation. All models (including those with an economizer) are suitable for either bottom or horizontal duct connections. For bottom duct, remove the sheet metal panels from the supply and return air openings through the base of the unit. For horizontal duct, remove the supply and return air panels on the rear of the unit. All models are available with the factory mounted outdoor air damper option: Single enthalpy economizer Supply air blowers are equipped with either a direct drive or a belt drive that can be adjusted to meet the exact requirements of the job. All compressors are equipped with internal pressure relief. Every refrigerant circuit includes a liquid line filter-drier, a high pressure switch and a suction line with a freezestat and low pressure/loss of charge switch to protect all system components. Control boards have standardized a number of features previously available only as options or by utilizing additional controls. Low Ambient - An integrated low-ambient control allows all units to operate in the cooling mode down to 0ºF outdoor ambient without additional assistance. Optionally, the control board can be programmed to lockout the compressors when the outdoor air temperature is low or when free cooling is available. Anti-Short Cycle Protection - To aid compressor life, an anti-short cycle delay is incorporated into the standard controls. Compressor reliability is further ensured by programmable minimum run times. For testing, the anti short cycle delay can be temporarily overridden with the push of a button. Fan Delays - Fan on and fan off delays are fully programmable and are independent of one another. All units are programmed with default values based upon their configuration of cooling and heat. Safety Monitoring - The control board monitors the high and low-pressure switches, the freezestats, the gas valve, if applicable, and the temperature limit switch on gas heat units. The unit control board will alarm on ignition failures, compressor lockouts and repeated limit switch trips. Nuisance Trip Protection- To prevent nuisance trouble calls, the control board uses a three strikes, you re out philosophy. The high and low-pressure switches and the freezestats must trip three times within two hours before the unit control board will lock out the compressor. On Board Diagnostics - Each alarm will energize a trouble light on the thermostat, if so equipped, and flash an alarm code on the control board LED. Each high and low-pressure switch alarm as well as each freezestat alarm has its own flash code. The control board saves the five most recent alarms in memory, and these alarms can be reviewed at any time. Alarms and programmed values are retained through the loss of power. All units have long lasting powder paint cabinets with 1000 hour salt spray test approval under ASTM-B117 procedures. All models are CSA listed. Warranty - All models include a one-year limited parts warranty on the complete unit. Compressors and electric heater elements carry a five-year warranty. Gas heat exchangers carry a 10-year parts warranty. Gas Heat Operation - All single phase models with gas heat have minimum annual fuel utilization efficiency (AFUE) of 80%. All three phase models with gas heat have minimum steady state efficiency of 80%. Each section includes a durable heat exchanger with aluminized steel, a redundant gas valve, spark ignition, power venting, an ignition module for 100% shut-off and all of the safety controls required to meet the latest ANSI standards. The gas supply piping can be routed into the heating compartment through a hole in the base pan of the unit or through a knockout in the piping panel on the front of the unit. Electric Heat Operation - All electric heat models are wired for a single power source and include a bank of nickel chromium elements mounted at the discharge of the supply air blower to provide a high velocity and uniform distribution of air across the heating elements. Every element is fully protected against excessive temperature by thermal limit switches. The power supply wiring can be routed into the control box through a threaded pipe connection (field supplied) in the base pan of the unit or through a knockout in the wiring panel on the side of the unit. 4 Unitary Products Group

The enthalpy system contains one sensor that monitors the outdoor air and determines when the air is cool enough and dry enough to provide free cooling. The rainhood is painted to match the basic unit and must be field-assembled before installing. PHENOLIC COATED CONDENSER COILS - Special coating process that utilizes Technicoat 10-1 TM processes. Coating is applied by total immersion of the complete coil for maximum protection. BELT DRIVE INDOOR FAN - Includes belt drive indoor fan and motor with unit access for belt adjustment and service. FIELD-INSTALLED ACCESSORIES SINGLE INPUT ELECTRONIC ENTHALPY ECONO- MIZERS - Includes a slide-in / plug-in damper assembly with fully modulating spring-return motor actuator capable of introducing up to 100% outdoor air with nominal 1% leakage type dampers.

The rainhood is painted to match the basic unit and must be field-assembled before installing. MOTORIZED OUTDOOR AIR INTAKE DAMPER - Includes a slide-in / plug-in damper assembly with a 2- position, spring return motor actuator which opens to some pre-set position whenever the supply air blower is operating and will drive fully closed when the blower unit shuts down. The rain hood is painted to match the basic unit and must be field assembled before installing. Unitary Products Group 5

6 ELECTRIC HEATERS wired for single point power supply. These nickel chromium heater elements are provided with limit and automatic reset capability to prevent operation at excessive temperatures. ROOF CURBS - Eight and fourteen-inch high roof curbs provide a water-tight seal between the unit and the finished roof. These full perimeter curbs meet the requirements of the National Roofing Contractors Association (NRCA) and are shipped knocked-down for field assembly. Roof curbs are designed to fit inside the base rails of the unit and include both a wood nailing strip and duct hanger supports. HIGH ALTITUDE NATURAL GAS - Burner orifices and pilot orifices are provided for proper furnace operation at altitudes up to 6,000 feet. PROPANE - Burner orifices, pilot orifices and gas valve parts are provided to convert a natural gas furnace to propane. HIGH ALTITUDE PROPANE - Burner orifices and pilot orifices are provided for proper furnace operation at altitudes up to 6,000 feet. This accessory supplements the basic propane conversion kit. LOW NOX KIT- Required to reduce the emission of nitrogen oxides below 40 nanograms per joule. POWER EXHAUST - Our single input economizer options are available with power exhaust. Whenever the outdoor air intake dampers are opened for free cooling, the exhaust fan will be energized to prevent the conditioned space from being over-pressurized during economizer operation. The power exhaust option can only be used on bottom duct configurations. BAROMETRIC RELIEF DAMPER - This damper accessory can be used to relieve internal building air pressure on units with an economizer without power exhaust. This accessory includes a rain hood, a bird screen and a fully assembled damper. With bottom duct connections, the damper should be mounted over the opening in the return air panel. With horizontal ductwork, the accessory should be mounted on the return air duct. ENTHALPY ACCESSORY CONTROL KIT - This kit contains the required components to convert a single enthalpy economizer to dual enthalpy. BURGLAR BARS - Mount in the supply and return openings to prevent entry into the duct work. FLUE EXHAUST EXTENSION KIT - In locations with wind or weather conditions which may interfere with proper exhausting of furnace combustion products, this kit can be installed to prevent the flue exhaust from entering nearby fresh air intakes. COIL GUARD - Customers can purchase a coil guard kit to protect the condenser coil from damage. This is not a hail guard kit. HAIL GUARD -Hail Guard Kit is available to prevent unit from hail damage. This is a sloped hood that fits above the condenser coil. GAS PIPING KIT - This kit supplies all necessary fittings and shut off valve. 6 Unitary Products Group
