Features and Benefits
Standard Features for Ultra High Efficiency 3-5 Ton
Units
• Efficiency – High efficiency units reach as high as 18.1
SEER and 14.35 EER. Gas/electric units have electronic
spark ignition and power vented combustion with steady
state efficiencies of 80%. These efficiencies exceed all
legislated minimum levels and provide low operating costs.
• Service Friendly – The Predator® incorporates a number
of enhancements which improve serviceability.
The motor and blower slide out of the unit as a common
assembly. This facilitates greater access to all the indoor
airflow components, thus simplifying maintenance and
adjustment.
Service time is reduced through the use of hinged,
toolless panels. Such panels provide access to frequently
inspected components and areas, including the control
box, compressors, filters, indoor motor & blower, and the
heating section. The panels are screwed in place at the
factory to prevent access by children or other
unauthorized persons. It is recommended that the panels
be secured with screws once service is complete.
Service windows have been placed in both condenser
section walls. Rotation of the cover allows easy access to
the condenser coils for cleaning or inspection.
Both the unit control board and ignition control board utilize
flash codes to aid in diagnosis of unit malfunctions. Unique
alarm codes quickly identify the source of the unit alarm.
All units use four filters of the same standard size. This
standardization simplifies selections for filter replacement.
The non-corrosive drain pan slides out of the unit to permit
easy cleaning. The drain pan is accessed by removing the
drain pan cover plate on the rear of the unit. Once the plate is
removed, the drain pan slides out through the rear of the unit.
All Predator® units have a second model nameplate
located inside the control access door. This is to prevent
deterioration of the nameplate through weathering.
• Simplicity® INTELLI-Comfort II™ Control w/
IntelliSpeed™ Supply Fan Control Option (ASHRAE
90.1 compliant, section 6.4.3.10) (Standard on Ultra
High Efficiciency 3 to 5 ton units) Communicates on a
MODBUS RTU protocol network - The York® Simplicity®
INTELLI-Comfort II™ control is factory installed. It includes
a supply air sensor, a return air sensor, and an outside air
sensor. There are provisions for a field installed dirty filter
indicator switch, an air-proving switch, an Outside Air
Humidity sensor, a Return Air Humidity sensor, an Inside
IAQ sensor, and an Outside Air IAQ sensor. Construction
mode operation, 365-day real time clock with 7 day
programming plus holiday scheduling is built-in. Two
different modes of demand ventilation are achieved through
the INTELLI-Comfort II™ using CO2 sensors. It uses an
inside CO2 sensor to perform Demand Ventilation. It can
also use an Outside CO2 sensor to perform Differential
Demand Ventilation. It uses a Patented Comfort Ventilation
algorithm to provide comfortable ventilation air
temperature. The patented economizer-loading algorithm
will protect the equipment when harsh operating conditions
4
exist. It uses the INTELLI-Start™ algorithm to maximize
energy savings by recovering the building from the
Unoccupied Setpoints to the Occupied Setpoints just in
time for the Occupied Time Period to begin. The
Simplicity® INTELLI-Comfort II™ balances space
temperature, ventilation air temperature and CO2 for
ultimate comfort. Units are configured with the
IntelliSpeed™ Supply Fan Option at the factory and will
contain a VFD for variable volume supply fan operation.
This option allows the supply fan RPM to vary based on the
stages of compression or heating stages energized. The
economizer's minimum position will also be configurable to
vary based on the supply fan VFD frequency output.
• Simplicity® INTELLI-Comfort II™ with Simplicity®LINC
Control - The York® Simplicity® INTELLI-Comfort II™
with Simplicity®LINC control is factory installed. It
includes all the features of the INTELLI-Comfort II™
control with an additional control to translate
communications from MODBUS to the BACnet MSTP
protocol.
• Indoor Motors - Units come from the factory with
Premium Efficiency, Inverter rated, Indoor Motor. Both
motor and belt drive blower are mounted on a slide out
assembly for ease of service.
• VFD - These factory supplied Variable Frequency Drives
come with a 5 year warranty from the manufacturer. They
also provide ease of commissioning without the need of a
computer to program the motor. That also provide a soft
start which equates to longevity of motor and belt life.
• Outdoor motors - Units come from the factory with long
lasting, high efficiency ECM motors.
• Coil Technology – All ZT condensers utilize MicroChannel “all-aluminum” condensers which provide
improved heat transfer capabilities and reduced charge
volumes. All evaporators utilize a conventional copper
tube/aluminum fin design for proven reliability and
performance.
• Environmentally Aware – For improved Indoor Air
Quality, a combination of foil faced and elastometric
rubber insulation is used exclusively throughout the units.
• Balanced Heating – The Predator® two stage gas heating
offers “Ultimate Heating Comfort” with a balance between
1st and 2nd stage gas heating. The first stage of a gas heat
Predator® unit provides 70% or 75% of the heating
capacity.
• Convertible Airflow Design – The side duct openings
are covered when they leave the factory. If a side supply/
return is desired, the installer simply removes the two side
duct covers from the outside of the unit and installs them
over the down shot openings. No panel cutting is required.
Convertible airflow design allows maximum field flexibility
and minimum inventory.
• System Protection - Suction line freezestats are supplied
on all units to protect against loss of charge and coil frosting
when the economizer operates at low outdoor air
temperatures while the compressors are running. Every unit
has solid-core liquid line filter-driers and high and lowpressure switches. Internal compressor protection is
standard on all compressors. Phase Monitors are standard
Johnson Controls Unitary Products

•
on units with scroll compressors. This accessory monitors
the incoming power to the unit and protects the unit from
phase loss and reversed phase rotation.
Advanced Controls - Simplicity® control boards have
standardized a number of features previously available
only as options or by utilizing additional controls.
The Simplicity® control board used in this product
will effectively operate the cooling system down to
0°F when this product is applied in a comfort cooling
application for people. An economizer is typically
included in this type of application. When applying
this product for process cooling applications (computer rooms, switchgear, etc.), please reference
applications bulletin AE-011-07 or call the applications department for Unitary Products @ 1-877UPG-SERV for guidance. Additional accessories
may be needed for stable operation at temperatures
below 30° F.
•
•
•
Anti-Short Cycle Protection - To aid compressor life,
an anti-short cycle delay is incorporated into the standard controls. Compressor reliability is further ensured
by programmable minimum run times. For testing, the
anti-short cycle delay can be temporarily overridden
with the push of a button.
•
•
Fan Delays - Fan on and fan off delays are fully programmable. Furthermore, the heating and cooling fan
delay times are independent of one another. All units
are programmed with default values based upon their
configuration of cooling and heat.
•
•
Safety Monitoring - The control board monitors the
high and low-pressure switches, the freezestats, the
gas valve, if applicable, and the temperature limit
switch on gas and electric heat units. The unit control
board will alarm on ignition failures, compressor lockouts and repeated limit switch trips.
•
Nuisance Trip Protection and Strikes - To prevent
nuisance trouble calls, the control board uses a “three
times, you’re out” philosophy. The high and low-pressure switches and the freezestats must trip three times
within two hours before the unit control board will lock
out the associated compressor.
•
On Board Diagnostics - Each alarm will energize a
trouble light on the thermostat, if so equipped, and
flash an alarm code on the control board LED. Each
high and low-pressure switch alarm as well as each
freezestat alarm has its own flash code. The control
board saves the five most recent alarms in memory,
and these alarms can be reviewed at any time.
Alarms and programmed values are retained through
the loss of power.
• Reliable – From the beginning – All units undergo
computer automated testing before they leave the factory.
Units are tested for refrigerant charge and pressure, unit
amperage, and 100% functionality. For the long term – All
Johnson Controls Unitary Products
•
Predator® units are painted with a long lasting, powder
paint that stands up over the life of the unit. The paint
used has been proven by a 1000 hour salt spray test.
Flexible Placement – All models and configurations
share the same cabinet/footprint and thus the same roof
curb. You have the flexibility to set one curb and choose
the correct tonnage size and heating option after the
internal loads have been determined.
To further simplify planning and installation, Predator®
cabinets are designed to fit your roof. With the optional
roof curb, the unit ductwork is designed to fit around 24”
on-center joists or between 48” on-center joists.
The drain pan can be rotated to drain to either the front or
the rear of the unit. Additionally, the drain pan can be
fitted to drain through the roof curb. As it is sometimes
difficult to have a level installation, the drain pan features
a generous slope to ensure proper drainage.
Full Perimeter Base Rails – The permanently attached
base rails provide a solid foundation for the entire unit and
protect the unit during shipment. The rails offer forklift
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 connections 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 handle
most airflow requirements. For high static applications,
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 10year warranty.

Altitude and Temperature Correction for CFM, Static Pressure and Power.
The information below should be used to assist in application of product when being applied at altitudes at or exceeding 1000 feet
above sea level.
The air flow rates listed in the standard blower performance tables are based on standard air at sea level. As the altitude or
temperature increases, the density of air decreases. In order to use the indoor blower tables for high altitude applications, certain
corrections are necessary.
A centrifugal fan is a "constant volume" device. This means that, if the rpm remains constant, the CFM delivered is the same
regardless of the density of the air. However, since the air at high altitude is less dense, less static pressure will be generated and
less power will be required than a similar application at sea level. Air density correction factors are shown in Table 14 and Figure 27.

Air Temperature (ºF)
The examples below will assist in determining the airflow performance of the product at altitude.
Example 1: What are the corrected CFM, static pressure, and BHP at an elevation of 5,000 ft. if the blower performance data is
6,000 CFM, 1.5 IWC and 4.0 BHP?
Solution: At an elevation of 5,000 ft. the indoor blower will still deliver 6,000 CFM if the rpm is unchanged. However, Table 13 must be
used to determine the static pressure and BHP. Since no temperature data is given, we will assume an air temperature of 70°F. Table
15 shows the correction factor to be 0.832.
Corrected static pressure = 1.5 x 0.832 = 1.248 IWC
Corrected BHP = 4.0 x 0.832 = 3.328
Example 2: A system, located at 5,000 feet of elevation, is to deliver 6,000 CFM at a static pressure of 1.5". Use the unit blower
tables to select the blower speed and the BHP requirement.
Solution: As in the example above, no temperature information is given so 70°F is assumed.

The 1.5" static pressure given is at an elevation of 5,000 ft. The
first step is to convert this static pressure to equivalent sea level
conditions.
Sea level static pressure = 1.5 / .832 = 1.80"
Enter the blower table at 6000 sCFM and static pressure of
1.8". The rpm listed will be the same rpm needed at 5,000 ft.
Suppose that the corresponding BHP listed in the table is 3.2.
This value must be corrected for elevation.
BHP at 5,000 ft. = 3.2 x .832 = 2.66

1. Add these values to the available static resistance in the respective Blower Performance Tables.
2. Deduct these values from the available external static pressure shown in the respective Blower Performance Tables.
3. The pressure drop through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return air duct
is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.
