265485-XTG-B-1208 • Convertible Airflow Design – The side duct openings are covered when they leave the factory. If a side supply/return is desired, the installer simply removes the two side duct covers from the outside of the unit and installs them over the down shot openings. No panel cutting is required. Convertible airflow design allows maximum field flexibility and minimum inventory.
265485-XTG-B-1208 • Wide Range of Indoor Airflows – All indoor fan motors are belt-drive type providing maximum flexibility to handle most airflow requirements. For high static applications, factory installed alternate indoor fan motors are available. With the optional indoor fan motor, all units can supply nominal airflow at a minimum of 1.5” (375 Pa) ESP.
265485-XTG-B-1208 • Technicoat Condenser Coils - The condenser coils are coated with a phenolic coating for protection against corrosion due to harsh environments. • Barometric Relief Damper - Zero to 100% capacity barometric relief dampers for use with horizontal flow, or field installed slab economizers. • Technicoat Evaporator Coil - The evaporator coils are coated with a phenolic coating for protection against corrosion due to harsh environments.
265485-XTG-B-1208 • 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. • Gas Piping Kit - Contains pipe nipples, fittings and gas cock required for gas supply connection with external shut off. • Electric Heaters - The electric heaters range from 9 kW to 54kW and are available in all the voltage options of the base units. All heaters are dual staged.

265485-XTG-B-1208 GUIDE SPECIFICATIONS PREDATOR® MagnaDRY™ DR 090 GENERAL Units shall be manufactured by Unitary Products in an ISO 9001 certified facility. YORK® Predator® MagnaDRY™ units are convertible single packages with a common footprint cabinet and common roof curb. All units have two compressors with independent refrigeration circuits to provide 2 stages of cooling. The units were designed for light commercial applications and can be easily installed on a roof curb, slab, or frame.
265485-XTG-B-1208 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.
2. air damper assembly to take in outdoor air to meet the minimum ventilation requirement of the conditioned space during normal operation. During economizer operation, a mixed-air temperature control shall modulate the outdoor and return air damper assembly to prevent the supply air temperature from dropping below 55 ºF/ 12.8°C. Changeover from compressor to economizer operation shall be provided by an integral electronic enthalpy control that feeds input into the basic module.
