FIELD INSTALLED ACCESSORIES

®
YORK offers several equipment accessories for field instal-
®
lation, for the Predator line.
• Downflow Economizer - (With barometric relief) - The
economizer is provided with a single enthalpy input. The
economizer is 2% low leakage type. 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 econo-
mizer control accepts an optional CO
ventilation. With single enthalpy input, the economizer
control monitors outdoor air. The dual enthalpy kit pro-
vides a second input used to monitor the return air. With
a dual input kit installed, the economizer control com-
pares the values of the two enthalpy or temperature
inputs and positions the dampers to provide the maxi-
mum 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 economizer.
• Dual Enthalpy Control, Accessory - This kit contains
the required components to convert a single enthalpy
economizer to dual enthalpy.
• Barometric Relief Damper - Zero to 100% capacity
barometric relief dampers for use with horizontal flow, or
field installed slab economizers.
• Power Exhaust - This accessory installs in the unit with
a down flow economizer. Power exhaust plugs into the
connector in the unit bulkhead. You must purchase
1EH0408 barometric relief/power exhaust hood when
applying to a horizontal flow application.
• Manual Outdoor Air Damper - Like the motorized out-
door 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 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.
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 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.
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.
-60°F Gas Heat Kit - For installations which require gas
heat units to perform in low ambient temperatures, a gas
section heating kit is available. This kit provides electric
heat in the gas heat controls section to ensure the gas
valve and controls will continue to function properly at
extremely low temperatures.
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 pro-
pane.
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.
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 9 kW
to 54kW 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 elec-
tric heaters. Necessary hardware and connectors are
included with the heaters. All heaters are intended for
single point power supply.
