Johnson Controls Unitary Products 3
FEATURES
• High Efficiency – High efficiency units are rated at 11.35
EER. Gas/electric units have electronic spark ignition and
power vented combustion with steady state efficiencies of
80%. These efficiencies meet or exceed all legislated min-
imum levels and provide low operating costs.
• Service Friendly – The Predator
®
Magnum incorpo-
rates a number of enhancements which improve service-
ability.
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 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 name-
plate located inside the control access door. This is to pre-
vent deterioration of the nameplate through weathering.
