Field Installed Accessories
®
YORK offers several equipment accessories for field
installation, for the Predator
• Down flow and End Return Economizers (with fresh air
hood and barometric relief) - All units offer a variety of
optional factory installed down flow economizers that are
shipped, installed and wired with low leak dampers designed
to meet ASHRAE 90.1, AMCA 511 Class 1A damper, and
the International Energy Conservation Code (IECC)
certification requirements by achieving leakage rates of 3
CFM/sq. ft. at 1" of static pressure. Each economizer goes
through a rigorous 60,000 cycle test. Dry bulb, single
enthalpy, and dual enthalpy (with field installed kit) can be
selected. 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
outdoor air dry bulb temperature or the outdoor air enthalpy
input. The dual enthalpy kit provides a second input used to
monitor the return air (field installed). The installer needs only
to assemble the outdoor air hood, attach the enthalpy control
the hood and mount the hood to the unit (Hood and control
are provided).
• Single or Dual Enthalpy Control, Accessories - These
kits contain the required components to convert a dry bulb
economizer to a single enthalpy and/or dual enthalpy
economizer.
• Barometric Relief Damper - Zero to 100% capacity
barometric relief dampers for use with horizontal flow, or
field installed economizers.
• Power Exhaust - This accessory installs in the unit with a
down flow or horizontal end return economizer. Power
exhaust plugs into the connector in the unit bulkhead.
User must purchase the 1EH0408 barometric relief
and hood kit when applying the product in a
horizontal flow application. The power exhaust must
be mounted in the horizontal end return ductwork.
• Manual Outdoor Air Damper - Like the motorized outdoor
air damper, each manual outdoor air damper includes a

slide-in damper assembly with an outdoor air hood and
filters. Customers have a choice of dampers with ranges of
0% to 100% or 0% to 35% outdoor air entry.
• Motorized Outdoor Air Damper - The motorized outdoor
air damper includes a slide-in/plug-in damper assembly with
an outdoor air hood and filters. The outdoor 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.
• 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.
• CO Sensor - Senses CO

overrides the economizer when levels rise above the
preset limits.
• Dirty Filter Switch - This kit includes a differential
pressure switch that energizes the fault light on the unit
thermostat, indicating that there is an abnormally high
pressure drop across the filters.
• Coil Guard - Field installed decorative wire coil guard.
• Hail Guard - This kit includes a sloped hood which installs
over the outside condenser coil and prevents damage to
the coil fins from hail strikes. Field installed accessory only.
• Flue Exhaust Extension Kit - In locations with wind or
weather conditions which may interfere with proper
exhausting of furnace combustion products, this kit can be
installed to prevent the flue exhaust from entering nearby
fresh air intakes.
• Gas Heat High Altitude Kit - This kit converts a gas heat
unit to operate at high altitudes, 2,000 to 6,000 feet.
Conversion kits are available for natural gas and propane.
• Gas Heat Propane Conversion Kit - This kit converts a
gas-fired heater from natural gas to propane. It contains the
main burner orifices and gas valve replacement springs.
• Low NOx Kit - For units with gas furnaces in locations
where codes require that the Oxides of Nitrogen
emissions from the furnace be below 40 Nano grams per
joule.
• Gas Piping Kit - Contains pipe nipples, fittings and gas cock
required for gas supply connection with external shut off.
• Electric Heaters - The electric heaters range from 3kW to
24kW and are available in all the voltage options of the
base units.
All heaters are dual staged. Cooling units include an
adapter panel for easy installation of the electric heaters.
Necessary hardware and connectors are included with the
heaters. All heaters are intended for single point power
supply.
• Metal Frame Filter Kit - Metal frame with polyester filter
medium.
• Permanent Filters - Permanent filters are available.
• Roof Curbs - The roof curbs have insulated decks and are
shipped disassembled The roof curbs are available in 8" and
14" heights. For applications with security concerns, burglar
bars are available for the duct openings of the roof curbs.
• Roof Curb Transition - Single Piece Adapter (10" High) -
Roof curbs for transitioning from Sunline™ units to
