Features and Benefits

Standard Features

• High Efficiency – High efficiency units reach as high as

12.2 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
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.

• Coil Technology – All ZH/ZJ 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. ZR037 thru 061 models utilize Micro­Channel condenser coils, ZR078 thru 150 models utilize
copper tube/aluminum fin condenser coils.

• 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
offers “Ultimate Heating Comfort” with a balance between

st

and 2nd stage gas heating. The first stage of a gas heat

1
Predator

®

unit provides 70% or 75% of the heating capacity
3 thru 5 tons and 60% heating capacity 6-1/2 thru 12-1/2
tons. Balanced heating allows the unit to better maintain
desired temperatures.

• Convertible Airflow Design – The side duct openings
are covered when they leave the factory. If a side supply/

®

incorporates a number

®

two stage gas heating

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. Scroll compressors do not
require crankcase heaters. Phase Monitors are standard 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.

• Low Ambient - An integrated low-ambient control

allows all units to operate in the cooling mode down to
0F outdoor ambient without additional assistance.
Optionally, the control board can be programmed to
lockout the compressors when the outdoor air tem

-

perature is low or when free cooling is available.

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 stan

­dard 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

Johnson Controls Unitary Products 5

528150-YTG-T-0514

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
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.

A variable air volume (VAV) option using a variable
frequency drive is available on 6-1/2 through 12-1/2 ton
models for applications requiring a constant supply duct
pressure. A differential pressure transducer is used to
monitor supply duct static pressure while a VAV control
board provides a speed reference signal to the VFD to
control the output of the indoor blower motor.

• 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.

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 economizers
with low leak dampers. The outdoor air enthal py se nsor
enables economizer operation if the outdoor enthalpy is
less than the setpoint of the economizer logic module. See
economizer options section to determine the correct
economizer for your application.

• Downflow Slab Economizers (with barometric relief

and fresh air hood) - 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 90.1-2010, 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). When selected with BAS Ready
Economizer Option the actuator requires 2-10 VDC
input from an external source, such as a field-installed
or factory-installed BAS controller. BAS-ready actuators
have an adjustable auxiliary end-switch for optional
power exhaust control.

• Horizontal Economizer - (Without barometric relief ) -

All features of the downflow economizer exist except
economizer is not designed with low leak dampers and
you must order the duct mount 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.

• For units with optional VAV or Simplicity® Intelli-Comfort
II™ control, a factory-installed, dry bulb sensor
determines if outdoor air temperature is low enough to
provide free-cooling operation. (Field-installed humidity
sensors for either outdoor air or outdoor & return air
streams are available for single enthalpy and differential
enthalpy configurations, respectively).

• VAV or Simplicity® INTELLI-Comfort II™ control, a
factory-installed dry bulb sensor determines if outdoor
air temperature is low enough to provide free-cooling
operation. (Field-installed humidity sensors for either
outdoor air or outdoor & return air streams are available
for single enthalpy and differential enthalpy
configurations, respectively.)

• Power Exhaust (Downflow only) - This accessory
installs in the unit with a down flow economizer.

• 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.

• 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.

• Variable Air Volume (VAV; 6-1/2 through 12-1/2 ton,
only - A factory-installed variable frequency drive (VFD),
mounted in the Blower Access compartment, is used to
control the speed of the indoor blower motor in order to
maintain a constant static pressure in the supply duct. A
pressure transducer and VAV control board are mounted
inside the control box. The drive comes completely wired
and pre-programmed from the factory.

An optional, factory-installed manual bypass switch
available with factory-installed VFD can be found in the
Blower Motor Access compartment. The switch can be
used to either route power to the VFD for modulating
control of the blower motor, to bypass the drive and
operate the motor at full speed, or to power the drive (and
not the motor) for diagnostic purposes.

Due to space limitations, VAV is not available with any of
the factory-installed BAS options, but is available with
'BAS-ready' models. Terminal blocks are provided in the
control box for field wiring of the customer-installed BAS.

A 'VFD-ready' option provides the provisions for a
customer-installed drive. The unit comes with a mounting
bracket installed in the Blower Access compartment which
may accommodate other vendor's drives depending on
their size. In order to utilize the unit's mounting bracket,
the maximum recommended drive dimensions are limited
to approximately 9" H x 5" W x 7.5" D.

If the drive will not fit in the allotted space, then it will have
to be mounted elsewhere; either within the building on a
perpendicular wall which is not subjected to excessive
temperature, vibration, humidity, dust, corrosive gas,

explosive gas, etc., or within an appropriate enclosure
rated for outside installation to safeguard against
moisture, dust and excessive heat. A terminal block
located in the control box is provided fo r fiel d co nn ection
of the VFD controls.

• IntelliSpeed™ Supply Fan Control Option (ASHRAE

90.1 compliant, section 6.4.3.10) - Units configured with

the IntelliSpeed™ Supply Fan Option will contain a VFD
for variable volume supply fan operation. This option
allows the supply fan RPM to vary based on the number
of compressors or heating stages energized. The
economizer's minimum position will also be configurable
to vary based on the supply fan VFD frequency output.

• Aluminized Steel Gas Heat Exchanger - For

with electric heat, a HACR breaker sized to the unit is
provided. For cooling only units, a switch sized to the
largest electric heat available for the particular unit is
provided. Factory installed option only.

• Convenience Outlet - (Non-Powered/Powered) - This
option locates a 120V single-phase GFCI outlet with cover,
on the corner of the unit housing adjacent to the
compressors. The “Non-powered” option requires the
installer to provide the 120V single-phase power source and
wiring. The “Powered” option is powered by a stepdown
transformer in the unit. 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 configurations.

• Filters - 2” Pleated MERV 7 or 4” Pleated MERV 13 are
available to meet LEED requirements. A 2” Throwaway is
shipped as standard.

Factory-installed smoke detectors may be subjected to
extreme temperatures during "off" times due to outside air
infiltration. These smoke detectors have an operational
limit of -4°F to 158°F. Smoke detectors installed in areas
that could be outside this range will have to be relocated to
prevent false alarms.

• 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.)
