Features and Benefits
Standard Features
• Service Friendly - The Predator® incorporates a number
of key features for ease of serviceability.
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 Smart Equipment™ 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 aluminum foil faced and
elastometric rubber insulations are used exclusively
throughout the units.
• Balanced Heating – The Predator
®
offers “Ultimate
Heating Comfort” with a balance between 1
st
and 2
nd
stage
gas heating. The first stage of a gas heat Predator
®
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. 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 - Smart Equipment™ control boards
have standardized a number of features previously
available only as options or by utilizing additional controls.
• Units will come with the new state of the art Smart
Equipment™ control system.
The new unit control
incorporates the best of the already proven Simplicity™
unitary controls and creates a more robust, intelligent
control. The goal of this control is to utilize cutting edge
technology making the equipment easier to install,
operate, and service. All units are Factory commissioned,
configured, and run tested.
• Versatile - The Smart Equipment™ control can be
configured to use with a standard thermostat (easy to
connect screw terminals), A zone sensor, or can be setup
to communicate with multiple BAS communication
protocols 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
The Smart Equipment™ 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-
877-UPG-SERV for guidance. Additional
accessories may be needed for stable operation at
temperatures below 30°F.
