YORK
Predator
units are convertible single packages with a
common footprint cabinet and common roof curb for all 3
through 12.5 ton models. The units are 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
you require the economizer option.
®
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 12.5 ton ZT models.
Tested in accordance with:

  • Page 75 5167821-YTG-K-1118 Altitude and temperature correction for CFM, static pressure, and power Use the information below to assist in the application of the product at altitudes at or exceeding 1000 feet above sea level. The air flow rates listed in the standard blower performance tables are based on standard air at sea level. As the altitude or temperature increases, the density of air decreases.
