Separate side and bottom <br /> openings shall be provided for the control wiring. <br /> STANDARD LIMITED WARRANTIES <br /> • Compressor 5 Years <br /> • Heat Exchanger 10 Years <br /> • Electric Heat Element 5 Years <br /> • Other Parts 1 Year <br /> OPTIONAL OUTDOOR AIR <br /> • Economizer—Outdoor and return air dampers that <br /> are interlocked and positioned by a fully-modulating, <br /> spring return damper actuator. The maximum leakage <br /> rate for the outdoor air intake dampers shall not <br /> exceed 2%when dampers are fully closed and <br /> operating against a pressure differential of 0.5 IWG. <br /> A unit-mounted potentiometer shall be provided to <br /> adjust the outdoor and return air damper assembly to <br /> take in CFM of outdoor air to meet the minimum <br /> ventilation requirement of the conditioned space <br /> during normal operation. During economizer <br /> operation, a mixed-air temperature control shall <br /> modulate the outdoor and return air damper <br /> assembly to prevent the supply air temperature from <br /> dropping below 55°F.The outdoor intake opening <br /> shall be covered with a rain hood that matches the <br /> exterior of the unit. Water eliminator/filters shall be <br /> provided. Simultaneous economizer/compressor <br /> operation is also possible. Dampers shall fully close <br /> on power loss. <br /> ADDITIONAL FACTORY INSTALLED OPTIONS <br /> • BAS Controls <br /> FIELD INSTALLED OPTIONS <br /> • Barometric Relief Damper—This damper accessory <br /> can be used to relieve internal building air pressure <br /> on units with an economizer without power exhaust. <br /> This accessory includes a rain hood, a bird screen <br /> and a fully assembled damper. With bottom duct <br /> connections, the damper should be mounted over the <br /> opening in the return air panel.With horizontal <br /> ductwork,the accessory should be mounted on the <br /> return air duct. <br /> Unitary Sales Tool v1.5.9.0 Information is subject to change without notice.Check local codes.
