•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.

•BAS Ready Economizer - The economizer is provided with a Belimo actuator that requires a 0-10V DC input from an external source (i.e., field installed building auto- mation system controller). Barometric relief or power exhaust options are available. 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.

FIELD INSTALLED ACCESSORIES

YORK® offers several equipment options/accessories for field installation, for the Predator Magnum line.

•-60°F Gas Heat Kit - For installations which require gas heat units to perform in low ambient temperatures, a gas section heating kit is available. This kit provides electric heat in the gas heat controls section to ensure the gas valve and controls will continue to function properly at extremely low temperatures.

•Barometric Relief - Zero to 100% capacity barometric relief damper for use with sideflow economizer.

•Burglar Bars - Mount in the supply and return openings to prevent entry into the duct work.

•CO2 Sensor - Senses CO2 levels and automatically overrides the economizer when levels rise above the preset limits.

•Coil Guard - Field installed decorative wire coil guard.

•Dirty Filter Switch - This kit includes a differential pres- sure switch that energizes the fault light on the unit ther- mostat, indicating that there is an abnormally high pressure drop across the filters.

•Enthalpy Accessory Control Kit - This kit contains the required components to convert a single enthalpy econo- mizer to dual enthalpy.

•Economizer (Downflow with barometric relief) - Econo- mizer with relief damper and single enthalpy input (2% low leakage damper).

Spring return fully modulating motor capable of introduc- ing up to 100% outside air. For power exhaust, add the power exhaust accessory.

•Economizer (Horizontal) - Horizontal economizers are designed to install in the lower return section on the side of the unit. It is specifically designed for horizontal return applications. 1EH0408 barometric relief/power exhaust hood must be purchased separately. The horizontal economizer is available with standard single enthalpy control. Dual enthalpy may be added by install- ing the dual enthalpy kit.

•Electric Heaters - The electric heaters range from 18 kW to 54kW and are available in all the voltage options of the base units. All heaters are dual staged. Cooling units include an adapter panel for easy installation of the electric heaters. Necessary hardware and connectors

036-21484-001-B-0103

are included with the heaters. All heaters are intended for single point power supply.

•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.

•Gas Heat High Altitude Kit – This kit converts a gas heat unit to operate at high altitudes, 2,000 to 6,000 feet. Conversion kits are available for natural gas and pro- pane.

•Gas Heat Propane Conversion Kit - This kit converts a gas-fired heater from natural gas to propane. It contains the main burner orifices and gas valve replacement springs.

•Hail Guard - This kit includes a sloped hood which installs over the outside condenser coil and prevents damage to the coil fins from hail strikes. Field installed accessory only.

•Manual Outdoor Air Damper - Like the motorized out- door air damper, each manual outdoor air damper includes a slide-in damper assembly with an outdoor air hood and filters. Customers have a choice of dampers with ranges of 0% to 100% or 0% to 35% outdoor air entry.

•Power Exhaust - This accessory installs in the unit with a down flow economizer. Power exhaust plugs into the connector in the unit bulkhead. You must purchase 1EH0408 barometric relief/power exhaust hood when applying to a sideflow application.

•Roof Curbs - The roof curbs have insulated decks and are shipped disassembled The roof curbs are available in 8” and 14” heights.

For applications with security concerns, burglar bars are available for the duct openings of the roof curbs.

•Roof Curb Adaptor Single Piece Adapter (10” High) - Roof curbs for transitioning from Sunline™ units to Pred- ator™ Magnum. Fits 7.5 to 12.5 Sunline™ roof curbs 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.

•Thermostat - The units are designed to operate with 24- volt electronic and electro-mechanical thermostats. All units (with or without an economizer) operate with two- stage heat/two-stage cool or two-stage cooling only ther- mostats, depending upon unit configuration.

•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.
