and protect the unit during shipment. The rails offer fork-
lift 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 connec-
tions 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 han-
dle most airflow requirements. For high static applica-
tions, 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 electric heater
elements each carry a 5-year warranty. Aluminized steel
and stainless steel tubular heat exchangers carry a 10-
year warranty.
FACTORY INSTALLED OPTIONS
YORK® offers several equipment options/accessories factory
installed, for the Predator

line.
• Alternate Indoor Blower Motor - For applications with
high restrictions, units are offered with optional indoor
motors that provide higher static output and/or higher air-
flow, depending upon the installer’s needs.
• Coil Guard - Customers can purchase a coil guard kit to
protect the condenser coil from damage. Additionally,
this kit stops animals and foreign objects from entering
the space between the inner condenser coil and the
main cabinet. This is not a hail guard kit.
• Convenience Outlet - (Non-Powered) - This option
locates a 120V GFCI single-phase outlet with cover on
the corner of the unit housing the compressors. The
installer must provide the 120V single-phase power
source and wiring. Factory installed option only.
• Dirty Filter Switch - This kit includes a differential pres-
sure switch that energizes the fault light on the unit ther-
mostat, indicating that there is an abnormally high
pressure drop across the filters. Factory installed option
or field installed accessory.
• Disconnect Switch - For gas heat units, a HACR
breaker sized to the unit is provided. For cooling units
with electric heat, a switch sized to the largest electric
heat available for the particular unit is provided. Factory
installed option only.
• Downflow Economizer - (With barometric relief) - The
economizer is provided with a single enthalpy input. The
economizer is 2% low leakage type. The economizers
are shipped installed and wired. The installer needs only
assemble and mount the outdoor air hood. The econo-
mizer has spring return, fully modulating damper actua-
tors 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 refrig-
eration to economizer operation is regulated by the stan-
dard single enthalpy input. There is an optional input
dual dry bulb available. To meet regulated air standards,
the economizer control accepts an optional CO
2
input for
demand ventilation.
With single enthalpy input, the economizer control moni-
tors 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.
• Sideflow Economizer - (Without barometric relief) - All
features as the downflow economizer exist except you
must order the barometric relief separately.
• Motorized Outdoor Air Damper - The motorized out-
door air damper includes a slide-in/plug-in damper
assembly with an outdoor air hood and filters. The out-
door air dampers open to the preset position when the
indoor fan motor is energized. The damper has a range
of 0% to 100% outdoor air entry. Factory installed option
or field installed accessory.
• Power Exhaust (Downflow only) - This accessory
installs in the unit with a down flow economizer. Power
exhaust plugs into the connector in the unit bulkhead.
• Smoke Detectors - The smoke detectors stop operation
of the unit by interrupting power to the control board if
smoke is detected within the air compartment.
• Stainless Steel Heat Exchanger - For applications in
corrosive environments, this option provides a full stain-
less steel heat exchanger assembly.
• Technicoat Condenser Coils - The condenser coils are
coated with a phenolic coating for protection against cor-
rosion due to harsh environments.
• Technicoat Evaporator Coil - The evaporator coil is
coated with a phenolic coating for protection against
harsh environments.
• Novar® BAS Control - The Novar® ETC-3 building
automation system controller is factory installed. Incudes
supply air sensor, return air sensor, dirty filter indicator
switch, and air proving switch.
• Johnson Controls BAS Control - The Johnson Control
YK-UNT-1126 building automation system controller is
factory installed. Includes supply air sensor, return air
sensor, dirty filter indicator switch, and air proving switch.
• CPC BAS Control - The Computer Process Controls
Model 810-3060 ARTC Advanced Rooftop building auto-
mation system controller is factory installed. Includes
supply air sensor, return air sensor, dirty filter indicator
switch, and air proving switch.
