1 862075-XTG-F-0513.. TECHNICAL GUIDE . R-410A Description ZF SERIES ASHRAE COMPLIANT. YORK Predator units are convertible single packages 7-1/2 THRU 12-1/2 TON with a common footprint cabinet and common roof curb for all 7-1/2 through 12-1/2 ton models. All units have two 50 Hz (Export) 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. All Predator units are self-contained and assembled on rigid full perimeter base rails allowing for 3-way forklift access and overhead rigging. Every unit is completely charged, wired, piped, and tested at the factory to provide a quick and easy field installation. All units are convertible between side and down airflow.

2 Independent economizer designs are used on side and down discharge applications, as well as all tonnage sizes. Predator units are available in the following configurations: cooling only, cooling with electric heat, and cooling with gas heat. Electric heaters are available as factory-installed options or field-installed accessories. All units provide constant supply air volume. ZF 7-1/2 AND 10 TON. ZF 12-1/2 TON.
