FEATURES
•
High Efficiency – High efficiency units are rated at 10.8
EER. Gas/electric units have electronic spark ignition
and power vented combustion with steady state efficien-
cies of 80%. These efficiencies meet or exceed all legis-
lated minimum levels and provide low operating costs.
Service time is reduced through the use of hinged, tool-
less 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 unautho-
rized persons. It is recommended that the panels be
secured with screws once service is complete.
•
Service Friendly – The Predator Magnum incorpo-
rates a number of enhancements which improve service-
ability.
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.
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.

lize flash codes to aid in diagnosis of unit malfunctions.
Unique alarm codes quickly identify the source of the
unit alarm.
testing, the anti-short cycle delay can be temporarily
overridden with the push of a button.
•
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 use the same standard filter size. This standard-
ization removes any confusion on which filter sizes are
needed for replacement.
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.
•
•
Phase Monitor - This accessory monitors the
incoming power to the unit and protects the unit from
phase loss and reversed phase rotation (Standard
on units with scroll compressors).
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.
All Predator™ Magnum units have a second model
nameplate located inside the control access door. This is
to prevent deterioration of the nameplate through weath-
ering.
•
•
Environmentally Aware – For improved Indoor Air
Quality, foil faced insulation is used exclusively through-
out the units.
•
•
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
three times within two hours before the unit control
board will lock out the associated compressor.
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.
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.
•
•
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 750 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.
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.
•
Advanced Controls -
control boards have
standardized a number of features previously available
only as options or by utilizing additional controls.
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.
•
•
Low Ambient - An integrated low-ambient control
allows all units to operate in the cooling mode down
to 0°F outdoor ambient without additional assis-
tance. Optionally, the control board can be pro-
grammed to lockout the compressors when the
outdoor air temperature is low or when free cooling
is available.
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.
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

assemble and mount the outdoor air hood. The econo-
mizer has spring return, fully modulating damper actua-
tors and is capable of introducing up to 100% outdoor air.
As the outdoor air intake dampers open, the return air
dampers close. The changeover from mechanical refrig-
eration to economizer operation is regulated by the stan-
dard single enthalpy input. There is an optional input
dual dry bulb available. To meet regulated air standards,

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.
the economizer control accepts an optional CO input for
2
demand ventilation.
With single enthalpy input, the economizer control moni-
tors outdoor air. The dual enthalpy kit provides a second
input used to monitor the return air. With a dual input kit
installed, the economizer control compares the values of
the two enthalpy or temperature inputs and positions the
dampers to provide the maximum efficiency possible.
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.
•
•
Sideflow Economizer - (Without barometric relief) - All
features as the downflow economizer exist except you

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.
Motorized Outdoor Air Damper - The motorized out-
door air damper includes a slide-in/plug-in damper
assembly with an outdoor air hood and filters. The out-
door air dampers open to the preset position when the
