OVEN SYSTEMS AND COMPONENTS
Filtering System
The filtering system consists of the following
components:
Grease filter
Catalytic converter
Grease Filter
The grease filter is located on the rear cavity wall
and helps remove grease and food particles from
the recirculating airflow. Checking the filter daily
is recommended to ensure optimal oven opera-
tion. See pages 5-8 for cleaning instructions.
Catalytic Converter
The catalytic converter, a VOC type catalyst, is
located behind the rear cook cavity wall and is
responsible for cleaning the recirculating airflow.
The catalyst functions by substantially lowering
the combustion temperature of grease entrained
in the air path to approximately the same tem-
perature of the airflow, thus the grease burns
and breaks down into CO
2
and H
2
O as it passes
through the catalytic converter. The catalyst will
operate most efficiently at temperatures above
475
º
F (246
º
C).
The catalytic converter is self-cleaning. It is not a
component that requires scheduled maintenance.
Additionally, the catalyst material is very sensi-
tive to certain chemical compounds. Irreversible
dam-age can occur if the catalyst is exposed to
cleaning chemicals containing phosphates, NaOH,
silicates, Na and Potassium Salts; therefore, use
only Turbo-Chef
Oven Cleaner when cleaning the
oven.
