ber of enhancements which improve serviceability.
The motor and blower slide out of the unit as a common
assembly. This facilit ates 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.
incorporates a num-
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 unit control board utilizes flash codes to aid in diagnosis of unit malfunctions. Unique flash 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.

•Environmentally Aware – For improved Indoor Air
Quality, foil faced insulation is used exclusively throughout the units.
•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 0°F (-17.8°C) 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 heating.
•Safety Monitoring - The control board monitors the
high and low-pressure switches, the freezestats and
the temperature limit switch on electric heat units.
The unit control board will alarm on 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
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. 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 750 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 after the internal loads have
been determined.
To further simplify planning and installation, Predator
cabinets are designed to fit your roof. With the optional
roof curb, the unit ductwork is designed to fit around 24”
(610 mm) on-center joists or between 48” (1219 mm) oncenter 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
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 – 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” (51 mm) 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 up to 1.5” (375 Pa) ESP.

FACTORY INSTALLED OPTIONS
YORK® offers several equipment options factory installed, for
the Predator® line.
•Optional Factory Installed Economizers - Predator
units offer a variety of optional factory installed economizers with low leak dampers. The outdoor air enthalpy
sensor enables economizer operation if the outdoor
enthalpy is less than the setpoint of the economizer logic
module. See Table 41 to determine the correct economizer for your application.
•Downflow Economizer - (With barometric relief) -
The economizer is provided with a single enthalpy
input. The economizer is 2% low leakage type, and is
shipped installed and wired. The installer needs only
to assemble and mount the outdoor air hood (Provided). The economizer has spring return, fully modulating damper actuators 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 refrigeration to economizer operation is regulated by the standard single
enthalpy input. There is an optional input dual dry
bulb available. To meet regulated air standards, the
economizer control accepts an optional CO
demand ventilation. With single enthalpy input, the
economizer control monitors 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.
•Horizontal Economizer - (Without barometric
relief) - All features as the downflow economizer
exist except you must order the barometric relief
separately. You must order a 1EH0408 if you are
installing a power exhaust. You can order a
1RD0411 Barometric Relief for horizontal flow
economizers only.
•BAS Ready Economizer -(With barometric relief)
- The economizer is provided with a Belimo actuator
that requires a 0-10V DC input from an external
source (i.e., field installed building automation system controller). Power exhaust options are available. The economizer is 2% low leakage type with
spring return and fully modulating dampers capable
of introducing up to 100% outside air. Also include 2”
(51 mm) pleated filters.
