Predator
®
units are convertible single packages
with a common footprint cabinet and common roof curb for
all 6-1/2 through 12-1/2 ton models. All units have two
compressors with independent refrigeration circuits to pro-
vide two stages of cooling. The units were designed for
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. A
independent economizer design is used on side and down
discharge applications, as well as all tonnage sizes.
Predator
®
units are available in the following configura-
tions: cooling only, cooling with electric heat, and cooling
with gas heat. Electric heaters are available as factory-
installed options or field-installed accessories.
