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.
®
Predator
units in all tonnage sizes are convertible between
side airflow and down airflow, with corresponding economizer if
economizer option is desired.
®
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.
