• 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.
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.
®
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
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® 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
0F outdoor ambient without additional assistance.
Optionally, the control board can be programmed to
lockout the compressors when the outdoor air temper
-
ature is low or when free cooling is available.
The Simplicity® 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 typically
included in this type of application. When applying
this product for process cooling applications (computer rooms, switchgear, etc.), please reference
applications bulletin AE-011-07 or call the applications department for Unitary Products @ 1-877UPG-SERV for guidance. Additional accessories
may be needed for stable operation at temperatures
below 30° F.
•Anti-Short Cycle Protection - To aid compressor life,
an anti-short cycle delay is incorporated into the stan
dard 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 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 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 lock
-
outs 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-pres

sure 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
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
ZF
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.
The drain pan can be rotated to drain to either the front or
the rear of the unit. Additionally, the drain pan can be
