YORK
Predator
MagnaDry™ units are convertible single
packages with a common footprint cabinet and common roof
curb for all 7-1/2 through 12-1/2 ton models. All units have
two 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
MagnaDry™ 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. Inde-
pendent economizer designs are used on side and down dis-
charge applications, as well as all tonnage sizes.
®
Predator
MagnaDry™ units are available in the following
configurations: cooling only, cooling with electric heat, and
cooling with gas heat. Electric heaters are available as fac-
tory-installed options or field-installed accessories.
®
The Predator
MagnaDry™ provides energy-savings, effi-
cient removal of moisture through a balanced coil design.
Because the unit doesn't increase sensible cooling, it allows
temperatures to be maintained within the comfort zone.
Unlike competitive systems, you're not subjected to over
cooling. You save through more efficient matching of dehu-
midification and cooling needs. This makes the MagnaDry™
perfect for applications that need to remove large amounts of
moisture or maintain low humidity levels.
Tested in accordance with:

You must purchase 1EH0408 barometric relief when applying to a hori- zontal flow application. •... - Page 10 When the room thermostat calls for second stage cooling, the RCB senses a signal through "Y1" & "Y2" and engages circuit #1 and circuit #2 in cooling mode. Indoor blower operation is initiated upon a call for first stage cooling, second stage cooling or dehumidification. Anytime there is a call for 2 stages of cooling, the unit will not operate in the reheat mode, even if there is a call for dehu- midification at "HUM".
