FEATURES

• High Efficiency – High efficiency units reach as high as
11.2 EER. Gas/electric units have electronic spark igni-
tion and power vented combustion with steady state effi-
ciencies 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, tool-
less 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 unautho-
rized 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 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.
