Factory Installed Options

YORK® offers several equipment options factory installed, for the Predator® line.

•Optional Factory Installed Economizers - Predator units offer a variety of optional factory installed econo- mizers with low leak dampers. The outdoor air enthalpy sensor enables economizer operation if the outdoor enthalpy is less than the setpoint of the economizer logic module. See Table 41 to determine the correct econo- mizer for your application.

•Downflow Economizer - (With barometric relief) - The economizer is provided with a single enthalpy input. The economizer is 2% low leakage type, and is shipped installed and wired. The installer needs only to assemble and mount the outdoor air hood (Pro- vided). The economizer has spring return, fully modu- lating damper actuators and is capable of introducing up to 100% outdoor air. As the outdoor air intake dampers open, the return air dampers close. The changeover from mechanical refrigeration to econo- mizer operation is regulated by the standard single enthalpy input. There is an optional input dual dry bulb available. To meet regulated air standards, the economizer control accepts an optional CO2 input for demand ventilation. With single enthalpy input, the economizer control monitors outdoor air. The dual enthalpy kit provides a second input used to monitor the return air. With a dual input kit installed, the econ- omizer control compares the values of the two enthalpy or temperature inputs and positions the dampers to provide the maximum efficiency possible.

•Horizontal Economizer - (Without barometric relief) - All features of the downflow economizer exist except you must order the duct mount baro- metric relief separately. You must order a 1EH0408 if you are installing a power exhaust. You can order a 1RD0411 Barometric Relief for horizontal flow economizers only.

•BAS Ready Economizer -(With barometric relief) - The economizer is provided with a Belimo actuator that requires a 0-10V DC input from an external source (i.e., field installed building automation sys- tem controller). Power exhaust options are avail- able. The economizer is 2% low leakage type with spring return and fully modulating dampers capable of introducing up to 100% outside air. Also include 2” pleated filters.

•Slab Economizer for Energy Recovery Ventilators- (With barometric relief and Fresh Air Hood) - The economizer is provided with a single enthalpy input. The economizer is 2% low leakage type, and is shipped installed and wired. The economizer has spring return, fully modulating damper actuators and is capable of introducing up to 100% outdoor air. As the outdoor air intake dampers open, the return air damp-

ers close. The changeover from mechanical refrigera- tion to economizer operation is regulated by the standard single enthalpy input. There is an optional input dual dry bulb available. To meet regulated air standards, the economizer control accepts an optional CO2 input for demand ventilation. With single enthalpy input, the economizer control monitors outdoor air. The dual enthalpy kit provides a second input used to mon- itor the return air. With a dual input kit installed, the economizer control compares the values of the two enthalpy or temperature inputs and positions the dampers to provide the maximum efficiency possible.

•Power Exhaust (Downflow only) - This accessory installs in the unit with a down flow economizer.

•Motorized Outdoor Air Damper - The motorized out- door air damper includes a slide-in/plug-in damper assembly with an outdoor air hood and filters. The out- door air dampers open to the preset position when the indoor fan motor is energized. The damper has a range of 0% to 100% outdoor air entry. Factory installed option or field installed accessory.

•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 applica- tions in non-corrosive environments.

•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 rust-proof stain- less steel drain pan is available to provide years of trou- ble-free operation in corrosive environments.

•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, an 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 - (Non-Powered /Powered) - This option locates a 120V single-phase GFCI outlet with cover, on the corner of the unit housing adjacent to the compressors. The “Non-powered” option requires the installer to provide the 120V single-phase power source and wiring. The “Powered” option is powered by a step- down transformer in the unit. Factory installed option only.

•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.
