supply air sensor, return air sensor, dirty filter indicator switch and air proving switch.

HONEYWELL BAS CONTROL - The Honeywell W7750C building automation system controller is factory installed. Includes air supply sensor, return air sensor, dirty filter indicator switch, and air proving switch.

•SMOKE DETECTORS - (supply air & return air) The smoke detectors stop operation of the unit by interrupting power to the control board if smoke is detected within the air compartment.

Factory installed smoke detectors in the return air, may be subjected to freezing temperatures during “off” times due to out side air infiltration. these smoke detectors have an operational limit of 32°F to 131°F. smoke detectors installed in areas that could be out side those limitations will have to be moved to prevent having false alarms.

•COIL GUARD - Customers can purchase a coil guard kit to protect the condenser coil from damage. This is not a hail guard kit.

•STAINLESS STEEL HEAT EXCHANGER - For applica- tions in corrosive environments, this option provides a full stainless steel heat exchanger assembly.

•STAINLESS STEEL DRAIN PAN- An optional rust-proof stainless steel drain pan is available to provide years of trouble-free operation in corrosive environments.

•PHASE MONITORS - Designed to prevent unit damage. The phase monitor will shut the unit down in an out-of- phase condition.

•HIGH SPEED DRIVE - Includes a belt and blower pulley upgrade to enhance blower performance.

•DIRTY FILTER SWITCH - This kit includes a differential pressure switch that energizes the fault light on the unit thermostat, indicating that there is an abnormally high pressure drop across the filters. Factory installed option or field installed accessory.

•HINGED FILTER DOOR/”TOOLESS” BLOWER AND ACCESS PANELS (not hinged) - This option allows for easy access and maintenance.

NOTE:Knobs are shipped separately within the unit to prevent shipping damage. These must be field installed for tool-less operation.

FIELD-INSTALLED ACCESSORIES

•SINGLE INPUT ELECTRONIC ENTHALPY ECONO- MIZERS - Includes a slide-in /plug-in damper assembly with fully modulating spring-return motor actuator capa-

for applications with a higher CFM and/or static pressure

ble of introducing up to 100% outdoor air with nominal 1% leakage type dampers.

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.

•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.

•ROOF CURBS - 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.

They're 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 alti- tudes up to 6,000 feet. This accessory supplements the basic propane conversion kit.

•SIDE DUCT FLANGES - One-inch flanges replace the supply and return air panels on the rear of the unit to accommodate horizontal duct connections. These flanges can also be used individually for bottom supply/ horizontal return or horizontal supply/bottom return. They cannot be used on units with power exhaust.

•BAROMETRIC RELIEF DAMPER - This damper acces- sory 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.

•HIGH SPEED DRIVE - A smaller blower pulley and a shorter belt increase the speed of the supply air blower

requirements.
