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 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 36 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 of the downflow economizer
exist except you must order the duct mount baro-
metric 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 an actuator that
requires a 0-10V DC input from an external source
(i.e., field installed building automation system con-
troller). 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”
pleated filters.
•
Slab Economizer for Energy Recovery Ventila-
tors
-
(With barometric relief and Fresh Air Hood)
- The economizer is provided with a single enthalpy
input. The economizer is 2% low leakage type, and
is shipped installed and wired. 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 regu-
lated 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 com-
pares the values of the two enthalpy or temperature
inputs and positions the dampers to provide the
maximum efficiency possible.
•
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.
•
Aluminized Steel Gas Heat Exchanger
- For applica-
tions in non-corrosive environments.
•
Stainless Steel Gas Heat Exchanger
- For applications
in corrosive environments, this option provides a full
stainless steel heat exchanger assembly.
•
Stainless Steel Drain Pan -
An optional rust-proof stain-
less steel drain pan is available to provide years of trou-
ble-free operation in corrosive environments.
