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 econo-
mizers 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 econo-
mizer 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 (Pro-
vided). The economizer has spring return, fully modu-
lating 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 econo-
mizer 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
2
input for
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 econ-
omizer 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 sys-
tem controller). Power exhaust options are avail-
able. 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.
• Power Exhaust (Downflow only) - This accessory
installs in the unit with a down flow economizer.
• 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.
• Alternate Indoor Blower Motor - For applications with
high static restrictions, units are offered with optional
indoor motors that provide higher static output and/or
higher airflow, depending upon the installer’s needs.
• Electric Heaters - The electric heaters range from 9kW
to 54kW and are available in all the voltage options of the
base units. All heaters are dual staged. All heaters are
intended for single point power supply.
• Disconnect Switch - For heat pumps with electric heat,
a HACR breaker sized to the unit is provided. For heat
pump only units, a switch sized to the largest electric
heat available for the particular unit is provided. Factory
installed option only.
• 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. Available
for both the supply and/or return air.
• Phase Monitors - Designed to prevent unit damage. The
phase monitor will shut the unit down in an out-of phase
condition. (Standard on units with Scroll Compressors.)
• 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.
• 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.
• 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 coils are
coated with a phenolic coating for protection against cor-
rosion due to 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.
Factory installed smoke detectors in the return air,
may be subjected to freezing temperatures during
"off" times due to out side air infiltration. These
smoke detectors have an operational limit of 32 °F
to 131°F. Smoke detectors installed in areas that
could be out side those limitations will have to be
moved to prevent having false alarms.
