FEATURES
•
Mid Efficiency
- Mid efficiency units reach as high as
10.4 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
®
incorporates a num-
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 fre-
quently 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.
