Both the unit control board and ignition control board uti-
lize 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 standard-
ization removes any confusion on which filter sizes are
needed for replacement.
The non-corrosive drain pan slides out of the unit to per-
mit easy cleaning. The drain pan is accessed by remov-
ing 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™ Magnum units have a second model
nameplate located inside the control access door. This is
to prevent deterioration of the nameplate through weath-
ering.
•
Environmentally Aware – For improved Indoor Air
Quality, foil faced insulation is used exclusively through-
out the units.
•
Balanced Heating – The Predator™ Magnum offers
"Ultimate Heating Comfort" with a balance between 1
nd
and 2
stage gas heating. The first stage of a gas heat
Predator™ Magnum unit provides 60% of the heating
capacity. Balanced heating allows the unit to better main-
tain desired temperatures.
•
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 sup-
plied 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
low-pressure switches. Internal compressor protection is
standard on all compressors. Crankcase heaters are
standard on reciprocating compressors. Scroll compres-
sors do not require crankcase heaters.
•
Advanced Controls -
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 assis-
tance. Optionally, the control board can be pro-
grammed 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
4
control boards have
S i m p l i c i t y
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 another. All
units are programmed with default values based
upon their configuration of cooling and heat.
•
Phase Monitor - This accessory monitors the
incoming power to the unit and protects the unit from
phase loss and reversed phase rotation (Standard
on units with scroll compressors).
•
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 con-
trol 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
st
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 com-
puter 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, pow-
der paint that stands up over the life of the unit. The paint
used has been proven by a 750 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™
Magnum 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
