246646-YTG-C-0606 • Environmentally Aware – For improved Indoor Air Quality, foil faced insulation is used exclusively throughout the units. • Balanced Heating – The Predator® offers “Ultimate Heating Comfort” with a balance between 1st and 2nd stage gas heating. The first stage of a gas heat Predator® unit provides 60% of the heating capacity. Balanced heating allows the unit to better maintain desired temperatures.

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. ® YORK offers several equipment options factory installed, for the Predator® line.
246646-YTG-C-0606 • Phase Monitors - Designed to prevent unit damage. The phase monitor will shut the unit down in an out-of phase condition. (Standard on units with Scroll Compressors.) • 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.

246646-YTG-C-0606 GUIDE SPECIFICATIONS PREDATOR® DH 078, 090, 102, 120 & 150, 11.5 EER GENERAL Units shall be manufactured by York International Unitary Products Group in an ISO 9001 certified facility. YORK® Predator® units are convertible single packages with a common footprint cabinet and common roof curb for all 6-1/2 through 12-1/2 ton models. All units have two compressors with independent refrigeration circuits to provide 2 stages of cooling.
246646-YTG-C-0606 Refrigerant Circuit and Refrigerant Safety Components shall include: A. Independent fixed-orifice or thermally operated expansion devices. B. Solid core filter drier/strainer to eliminate any moisture or foreign matter. C. Accessible service gage connections on both suction and discharge lines to charge, evacuate, and measure refrigerant pressure during any necessary servicing or troubleshooting, without losing charge. D.
outdoor and return air damper assembly to prevent the supply air temperature from dropping below 55 ºF. Changeover from compressor to economizer operation shall be provided by an integral electronic enthalpy control that feeds input into the basic module. The outdoor intake opening shall be covered with a rain hood that matches the exterior of the unit. Water eliminator/filters shall be provided. Simultaneous economizer/compressor operation is also possible. Dampers shall fully close on power loss.
