•Motorized Outdoor Air Damper - The motorized outdoor air damper includes a
•Alternate Indoor Blower Motor - For applications with high static restrictions, units are offered with optional indoor motors that provide higher static output and/or higher airflow, depending upon the installer’s needs.
•Aluminized Steel Gas Heat Exchanger - For applications in
•Stainless Steel Gas Heat Exchanger - For applications in corrosive environments, this option provides a full stainless steel heat exchanger assembly.
•Stainless Steel Drain Pan - An optional
•Electric Heaters - The electric heaters range from 9kW to 54kW and are available in all the voltage options of the base units. All heaters are dual staged. All heaters are intended for single point power supply.
•Disconnect Switch - For gas heat units and cooling units with electric heat, a HACR breaker sized to the unit is provided. For cooling only units, a switch sized to the largest electric heat available for the particular unit is provided. Factory installed option only.
•Convenience Outlet -
•Smoke Detectors - The smoke detectors stop operation of the unit by interrupting power to the control board if smoke is detected within the air compartment. Available for both the supply and/or return air.
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.
•Phase Monitors - Designed to prevent unit damage. The phase monitor will shut the unit down in an
•Coil Guard - Customers can purchase a coil guard kit to protect the condenser coil from damage. Additionally, this kit stops animals and foreign objects from entering the space between the inner condenser coil and the main cabinet. This is not a hail guard kit.
•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.
•Technicoat Condenser Coils - The condenser coils are coated with a phenolic coating for protection against corrosion due to harsh environments.
•Technicoat Evaporator Coil - The evaporator coils are coated with a phenolic coating for protection against corrosion due to harsh environments.
•Hot Gas Bypass - Allows operation during low load conditions while avoiding coil frosting and damage to compressor. When suction pressure falls below valve setpoint, the valve modulates hot gas to the inlet of the evaporator.
