Toolless hinged panels

• Service time is reduced through the use of hinged,
toolless panels. The panels provide access to
frequently inspected components and areas, including
the control box, compressors, filters, indoor motor and
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.
• All units use four filters of the same standard size. This standardization simplifies selections for filter replacement.
®
• All Predator units have a second model nameplate located inside the control access door. This is to prevent deterioration of
the nameplate through weathering.
• 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.
• The Smart Equipment™ control board provides alarm messages to help quickly identify any faults.

Indoor motors

Units come from the factory with premium efficiency, inverter rated, indoor motors. Both motor and belt drive blower are
mounted on a slide out assembly for ease of service.

Variable frequency drive

These factory supplied variable frequency drives come
with a 5-year warranty from the manufacturer. They also
provide ease of commissioning without the need for a
computer to program the motor and soft start capabilities
for longer motor and belt life.

ECM outdoor motors

Units come from the factory with long lasting, high
efficiency ECM motors.
Microchannel coil technology
All ZT condensers use microchannel all-aluminum
condensers which provide improved heat transfer
capabilities and reduced charge volumes.
Evaporator coil technology
• 6.5 to 12.5 ton units use new sine wave fin geometry in
a copper tube/aluminum fin evaporator coil for increased
unit efficiency.
Environmentally aware
For improved Indoor Air Quality, a combination of aluminum foil faced and elastometric rubber insulations are used exclusively
throughout the units.
