DESCRIPTION
ASHRAE 90.1 COMPLIANT
YORK® Predator® MagnaDry™ units are convertible single
packages with a common footprint cabinet and common roof
curb for all 7-1/2 through 12-1/2 ton models. All units have
two compressors with independent refrigeration circuits to
provide 2 stages of cooling. The units were designed for light
commercial applications and can be easily installed on a roof
curb, slab, or frame.
®
All Predator
assembled on rigid full perimeter base rails allowing for 3-way
forklift access and overhead rigging. Every unit is completely
charged, wired, piped, and tested at the factory to provide a
quick and easy field installation.
All units are convertible between side and down airflow. Independent economizer designs are used on side and down discharge applications, as well as all tonnage sizes.
Predator
configurations: cooling only, cooling with electric heat, and
cooling with gas heat. Electric heaters are ava ilable as factory-installed options or field-installed accessories.
The Predator® MagnaDry™ provides energy-savings, efficient removal of moisture through a balanced coil design.
Because the unit doesn’t increase sensible cooling, it allows
temperatures to be maintained within the comfort zone.
Unlike competitive systems, you’re not subjected to over
cooling. You save through more efficient matching of dehumidification and cooling needs. This makes the MagnaDry™
perfect for applications that need to remove large amounts of
moisture or maintain low humidity levels.
MagnaDry™ units are self-contained and

FEATURES
• High Efficiency – High efficiency units reach as high as
11.2 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
ber 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.
incorporates a num-
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 the same standard filter size. This standardization removes any confusion on which filter sizes are
needed for 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.
• Environmentally Aware – For improved Indoor Air Quality,
foil faced insulation is used exclusively throughout the units.
®
• Balanced Heating – The Predator
ing Comfort” with a balance between 1
gas heating. The first stage of a gas heat Predator
offers “Ultimate Heat-
st
and 2nd stage
®
unit
provides 60% of the heating capacity. 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/
Unitary Products Group 5
246721-YTG-C-0606
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. Crankcase heaters are standard
on reciprocating 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 temperature is low or when free cooling
is available.
• 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 pro-
grammable. Furthermore, the heating and cooling
fan delay times are independent of one ano ther. 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 th e 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.
• 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

Demand Ventilation. It can also use an Outside CO
2
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 exist. Humidity in the
occupied space or return duct can be monitored and
controlled via humidity sensors and the on-board
connection for hot gas re-heat system. 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™
balances space temperature, ventilation air temperature,
and humidity for ultimate comfort.

REHEA T MODE SEQUENCE OF OPERATION
The reheat control board allows the user to select two different modes of operation via a jumper connection on the
board. (See Figure 3.) Each mode is described below. Refer
to Figures 3 - 5 when reading this section.
“NORMAL” MODE
When the reheat control board (RCB) detects a need for
dehumidification (24VAC) at "HUM" via the field supplied
dehumidistat connected to RHTB-1 and RHTB-2 and there is
not a call for cooling, it energizes the hot gas rel ay (HGR),
which energizes the 3-way valve (SOL 3), the condenser coil
valve (SOL 2), and de-energizes the reheat coil bleed va lve
(SOL 1). (In the DR150, SOL 2 is only energized when the
discharge pressure in circuit #1 rises above 235 psig and deenergizes SOL 2 after the discharge pressure falls below 175
psig. Both outdoor fans of circuit #1 in the DR150 also disengage to conserve energy.) The Y1 signal is passed to the unit
control board (UCB), which engages circuit # 1, resulting in
circuit #1 reheat mode operation.
When the room thermostat calls for first stage cooling, with or
without a call for dehumidification, the RCB senses a signal
through "Y1", de-energizing the HGR, which de-energizes
SOL 3 and SOL 2 and energizes SOL 1, engaging circuit #1,
resulting in circuit #1 cooling mode operation.
Unitary Products Group 9
246721-YTG-C-0606
When the room thermostat calls for second stage cooling, the
RCB senses a signal through "Y1" & "Y2" and engages circuit
#1 and circuit #2 in cooling mode.
Indoor blower operation is initiated upon a call for first stage
cooling, second stage cooling or dehumidification.
Anytime there is a call for 2 stages of cooling, the unit will not
operate in the reheat mode, even if there is a call for dehumidification at "HUM".
The unit will not operate in the reheat mode if there is any call
for heating.
On units with economizers, the unit will not operate in the
reheat mode if there is a call for cooling and the economizer
is operating as first stage of cooling.
All safety devices function as previously described.
"AL TERNATE” MODE
When the RCB detects a need for dehumidification (24VAC)
at "HUM" via the field supplied dehumidistat connected to
RHTB-1 and RHTB-2, and there is not a call for cooling, it
energizes the HGR, which energizes the SOL 3, SOL 2, and
de-energizes SOL 1. (In the DR150, SOL 2 is only energized
when the discharge pressure in circuit #1 rises above 235
psig and de-energizes SOL 2 after the discharge pressure
falls below 175 psig. Both outdoor fans of circuit #1 in the
DR150 also disengage to conserve energy.) The unit then
operates with circuit #1 in reheat mode and circuit #2 i n cooling mode.
When the room thermostat calls for first stage cooling while
there is still a call for dehumidification, no operational change
is made. The call for cooling is ignored and the unit continues
to operate with circuit #1 in reheat mode and circuit #2 in
cooling mode.
When the room thermostat calls for second stage cooling, the
RCB senses a signal through "Y1" and "Y2" and de-energizes the HGR, which de-energizes SOL 3 and SOL 2, and
energizes SOL 1. Both circuits operate in the cooling mode.
Indoor blower operation is initiated upon a call for first stage
cooling, second stage cooling or dehumidification.
Anytime there is a call for 2 stages of cooling, the unit will not
operate in the reheat mode, even if there is still a call for
dehumidification at "HUM".
The unit will not operate in the reheat mode if there is any call
for heating.
All safety devices function as previously described.
