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 minimum levels and provide low operating costs.
®
• Service Friendly – The Predator
Magnum incorporates a number of enhancements which improve serviceability.
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.
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.
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 utilize flash codes to aid in diagnosis of unit malfunctions.
Unique alarm codes quickly identify the source of the
unit alarm.
All units use the same standard filter size. This standardization removes any confusion on which filter sizes are
needed for replacement.
The non-corrosive drain pan slides out of the unit to permit easy cleaning. The drain pan is accessed by removing 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.

• Environmentally Aware – For improved Indoor Air
Quality, foil faced insulation is used exclusively throughout the units.
• Balanced Heating – The Predator® Magnum offers
“Ultimate Heating Comfort” with a balance between 1
and 2nd 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 maintain 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.
• System Protection – Suction line freezestats are supplied 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 compressors do not require crankcase heaters. Phase monitors
are standard on all units.
• Advanced Controls - Simplicity™ control boards have
standardized a number of features previously available
only as options or by utilizing additional controls.
• 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 temperature is low or when free cooling is available.
• 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.
• Fan Delays - Fan on and fan off delays are fully pro-
grammable. Furthermore, the heating and cooling
fan delay times are independent of one ano ther. All
units are programmed with default values based
upon their configuration of cooling and heat.
• 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 control board will alarm on ignition failures, compressor
lockouts and repeated limit switch trips.
• 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.
• On Board Diagnostics - Each alarm will energize a
st
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.
• Reliable – From the beginning – All units undergo computer 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, powder paint that stands up over the life of the unit. The paint
used has been proven by a 1000 hour salt spray test.
• 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 joist s.
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.
• 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.
• 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 connections can be made quickly and with a minimum amount
of field labor.
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 handle most airflow requirements. For high static applications, 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.
• Warranty - All models include a 1-year limited warranty
on the complete unit. Compressors and e lectric heater
elements each carry a 5-year warranty. Aluminized steel
and stainless steel tubular heat exchangers carry a 10year warranty.

dampers shall not exceed 2% when dampers are fully
closed and operating against a pressure differential of
0.5 IWG . A unit-mounted potentiometer shall be provided
to adjust the outdoor and return air damper assembly to
take in the design CFM of outdoor air to meet the ventilation requirements of the conditioned space during normal
operation. Whenever the indoor fan motor is energized,
the dampers open up to one of two pre-selected positions – regardless of the outdoor air enthalpy. Dampers
return to the fully closed position when the indoor fan
motor is de-energized. Dampers shall fully close on
power loss.
