FEATURES  
High Efficiency – High efficiency units are rated at 11.35  
EER. Gas/electric units have electronic spark ignition and  
power vented combustion with steady state efficiencies of  
80%. These efficiencies meet or exceed all legislated min-  
imum levels and provide low operating costs.  
Service windows have been placed in both condenser  
section walls. Rotation of the cover allows easy access  
to the condenser coils for cleaning or inspection.  
Both the unit control board and ignition control board uti-  
lize flash codes to aid in diagnosis of unit malfunctions.  
Unique alarm codes quickly identify the source of the  
unit alarm.  
®
Service Friendly – The Predator Magnum incorpo-  
rates a number of enhancements which improve service-  
ability.  
All units use the same standard filter size. This standard-  
ization removes any confusion on which filter sizes are  
needed for replacement.  
The motor and blower slide out of the unit as a common  
assembly. This facilitates greater access to all the indoor  
airflow components, thus simplifying maintenance and  
adjustment.  
The non-corrosive drain pan slides out of the unit to per-  
mit easy cleaning. The drain pan is accessed by remov-  
ing the drain pan cover plate on the rear of the unit. Once  
the plate is removed, the drain pan slides out through the  
rear of the unit.  
Service time is reduced through the use of hinged, toolless  
panels. Such panels provide access to frequently  
inspected components and areas, including the control  
box, compressors, filters, indoor motor & blower, and the  
heating section. The panels are screwed in place at the  
factory to prevent access by children or other unauthorized  
persons. It is recommended that the panels be secured  
with screws once service is complete.  
®
All Predator Magnum units have a second model name-  
plate located inside the control access door. This is to pre-  
vent deterioration of the nameplate through weathering.

Environmentally Aware – For improved Indoor Air  
Quality, foil faced insulation is used exclusively through-  
out the units.  
three times within two hours before the unit control  
board will lock out the associated compressor.  
On Board Diagnostics - Each alarm will energize a  
trouble light on the thermostat, if so equipped, and  
flash an alarm code on the control board LED. Each  
high and low-pressure switch alarm as well as each  
freezestat alarm has its own flash code. The control  
board saves the five most recent alarms in memory,  
and these alarms can be reviewed at any time.  
Alarms and programmed values are retained  
through the loss of power.  
®
Balanced Heating – The Predator Magnum offers  
st  
“Ultimate Heating Comfort” with a balance between 1  
nd  
and 2 stage gas heating. The first stage of a gas heat  
Predator Magnum unit provides 60% of the heating  
®
capacity. Balanced heating allows the unit to better main-  
tain desired temperatures.  
Convertible Airflow Design – The side duct openings  
are covered when they leave the factory. If a side supply/  
return is desired, the installer simply removes the two  
side duct covers from the outside of the unit and installs  
them over the down shot openings. No panel cutting is  
required. Convertible airflow design allows maximum  
field flexibility and minimum inventory.  
Reliable – From the beginning – All units undergo com-  
puter automated testing before they leave the factory.  
Units are tested for refrigerant charge and pressure, unit  
amperage, and 100% functionality. For the long term –  
®
All Predator units are painted with a long lasting, pow-  
der paint that stands up over the life of the unit. The paint  
used has been proven by a 1000 hour salt spray test.  
System Protection – Suction line freezestats are sup-  
plied on all units to protect against loss of charge and coil  
frosting when the economizer operates at low outdoor air  
temperatures while the compressors are running. Every  
unit has solid-core liquid line filter-driers and high and  
low-pressure switches. Internal compressor protection is  
standard on all compressors. Crankcase heaters are  
standard on reciprocating compressors. Scroll compres-  
sors do not require crankcase heaters. Phase monitors  
are standard on all units.  
Flexible Placement – All models and configurations  
share the same cabinet/footprint and thus the same roof  
curb. You have the flexibility to set one curb and choose  
the correct tonnage size and heating option after the  
internal loads have been determined.  
®
To further simplify planning and installation, Predator  
Magnum cabinets are designed to fit your roof. With the  
optional roof curb, the unit ductwork is designed to fit  
around 24” on-center joists or between 48” on-center joists.  
Advanced Controls - S implicitycontrol boards have  
standardized a number of features previously available  
only as options or by utilizing additional controls.  
The drain pan can be rotated to drain to either the front  
or the rear of the unit. Additionally, the drain pan can be  
fitted to drain through the roof curb. As it is sometimes  
difficult to have a level installation, the drain pan features  
a generous slope to ensure proper drainage.  
Low Ambient - An integrated low-ambient control  
allows all units to operate in the cooling mode down  
to 0°F outdoor ambient without additional assistance.  
Optionally, the control board can be programmed to  
lockout the compressors when the outdoor air tem-  
perature is low or when free cooling is available.  
Full Perimeter Base Rails – The permanently attached  
base rails provide a solid foundation for the entire unit  
and protect the unit during shipment. The rails offer  
forklift access from 3 sides, and rigging holes are  
available so that an overhead crane can be used to  
place the units on a roof.  
Anti-Short Cycle Protection - To aid compressor  
life, an anti-short cycle delay is incorporated into the  
standard controls. Compressor reliability is further  
ensured by programmable minimum run times. For  
testing, the anti-short cycle delay can be temporarily  
overridden with the push of a button.  
Easy Installation – Gas and electric utility knockouts are  
supplied in the unit underside as well as the side of the  
unit. A clearly identified location is provided to mount a  
field supplied electrical disconnect switch. Utility connec-  
tions can be made quickly and with a minimum amount  
of field labor.  
Fan Delays - Fan on and fan off delays are fully pro-  
grammable. Furthermore, the heating and cooling  
fan delay times are independent of one another. All  
units are programmed with default values based  
upon their configuration of cooling and heat.  
All units are shipped with 2” throw-away filters installed.  
Wide Range of Indoor Airflows – All indoor fan motors  
are belt-drive type providing maximum flexibility to han-  
dle most airflow requirements. For high static applica-  
tions, factory installed alternate indoor fan motors are  
available. With the optional indoor fan motor, all units can  
supply nominal airflow at a minimum of 1.5” ESP.  
Safety Monitoring - The control board monitors the  
high and low-pressure switches, the freezestats, the  
gas valve, if applicable, and the temperature limit  
switch on gas and electric heat units. The unit con-  
trol board will alarm on ignition failures, compressor  
lockouts and repeated limit switch trips.  
Warranty - All models include a 1-year limited warranty  
on the complete unit. Compressors and electric heater  
elements each carry a 5-year warranty. Aluminized steel  
and stainless steel tubular heat exchangers carry a 10-  
year warranty.  
Nuisance Trip Protection and Strikes - To prevent  
nuisance trouble calls, the control board uses a  
“three times, you’re out” philosophy. The high and  
low-pressure switches and the freezestats must trip

Add these resistance values to the available static resistance in the respective Blower Performance Tables.  
Deduct these resistance values from the available external static pressure shown in the respective Blower Performance Table.  
The pressure drop through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return  
air duct system is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.
