Magnum is a convertible single package unit
with a common footprint cabinet and common roof curb for 12-
1/2 ton models. All units have two compressors with indepen-
dent 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
®
Magnum 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
®
Magnum units are available in the following configu-
rations: cooling only, cooling with electric heat, and cooling with
gas heat. Electric heaters are available as factory-installed
options or field-installed accessories.

- 1. Compressor Lockout (CLO): To prevent mechanical (compressorized) operation of the unit during cold outdoor conditions where there is a risk of returning liquid refrigerant back to the compressors.
- 2. Low Limit Control (LLC): To prevent the supply air from dropping below a specified setpoint by utilizing the units first stage heating means when there is a demand for cooling during cold outside conditions.
