Features and Benefits
Standard Features
• High Efficiency – High efficiency units reach as high as
11.2 EER. Gas/electric units have electronic spark ignition
and power vented combustion with steady state efficiencies
of 80%. These efficiencies exceed all legislated minimum
levels and provide low operating costs.
• Service Friendly – The Predator
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.
The Simplicity® SE control board provides alarm
messages to help quickly identify any faults.
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.
®
All Predator
units have a second model nameplate
located inside the control access door. This is to prevent
deterioration of the nameplate through weathering.
• Coil Technology – ZF condensers utilize Micro-Channel
“all aluminum” condensers which provide improved heat
transfer capabilities and reduced charge volumes.
• Environmentally Aware – For improved Indoor Air
Quality, a combination of foil faced and elastometric
rubber insulation is used exclusively throughout the units.
• Balanced Heating – The Predator
Heating Comfort” with a balance between 1
gas heating. The first stage of a gas heat Predator
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
®
incorporates a number

offers “Ultimate
st
and 2nd stage
®
temperatures while the compressors are running. Every unit
has solid-core liquid line filter-driers and high and lowpressure 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 units with scroll compressors. This accessory
monitors the incoming power to the unit and protects the
unit from phase loss and reversed phase rotation.
• Advanced Controls - Simplicity® SE control boards have
standardized a number of features previously available only
as options or by utilizing additional controls.
The Simplicity® SE control board used in this
product will effectively operate the cooling system
down to 0°F when this product is applied in a comfort
cooling application for people. An economizer is

to integrate with building automation systems.
• Reduce field installed complexity - Each unit will comes
equipped with factory installed supply air, return air, and
outdoor air temperature sensors providing key
temperature readings thus reduce field installed
complexity.
• On-board USB Port - The new control comes with a long
list of features including data logging, current and
previous system faults and software update capabilities
using the on board USB port and common flash drive.
Energy use monitoring capabilities allow custom tailoring
to allow a system to work more efficiently at all times and
occupancy levels. Self test and start-up reports also
available from the board VIA the USB port.
• Embedded LCD Display - The board has a easy to read,
built-in LCD display and easy to use navigation joystick
and buttons allowing the user to quickly navigate the
menus displaying unit status, options, current function,
supply, return and outdoor temperatures, fault codes and
other information.
• Safety Monitoring - The control monitors the outdoor,
supply, and return air temperatures and the high and low
pressure switch status on the independent refrigerant
circuits. On units with heating the gas valve and high
temperature limit switches are monitored on gas and
electric heating units. The control also monitors the
voltage supplied to the unit and will protect the unit if low
voltage due to a brown out, or other electrical issue
occurs.
• Low Ambient - An integrated low-ambient control allows
units to operate in the cooling mode down to 0°F outdoor
ambient without additional components or intervention.
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
control. Compressor reliability is further ensured by
programmable minimum run times. For testing, the antishort cycle delay can be temporarily overridden with the
push of a button.
• Fan Delays - Fan on and fan off delays are fully
programmable. 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/or heating capacity.
• Nuisance Trip Protection and Three Strikes - To
prevent nuisance calls, the control board uses a three
times, you're out philosophy. The high, low-pressure
switch, anti-freeze protection, low voltage or heating high
limit must trip three times within two hours before the unit
control board will lock out the associated compressor.An
alarm message will be displayed on the LCD screen.
• Lead-Lag - An integrated Lead-Lag option allows equal
run time hours on all compressors, thereby extending the
life of all compressors. This option is selectable on the unit
control board.
• Low Limit Control (LLC) - To prevent the supply air from
dropping below a specified set point, when there is a
demand for cooling during cold outside conditions.
(Programmable Set point)
• 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
