YORK
Predator
units are convertible single packages with a
common footprint cabinet and common roof curb for all 3
through 5 ton models. 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.
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 meet ASHRAE 90.1 single-zone variable supply air
volume standard. Featuring a variable frequency drive on 3
through 5 ton ZT models.
Tested in accordance with:
