Filtering System

This section contains information about the
following components:

• Catalytic converter

• Air filter

Catalytic Converter
The catalytic converter, a VOC type catalyst, is
located behind the inside 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 temperature
of the airflow; thus the grease burns and breaks
down into CO2 and H2O as it passes through the
catalytic converter. The catalyst will operate most
efficiently at temperatures above 475ºF (246ºC).
The catalyst material is very sensitive to certain
chemical compounds. Irreversible damage can occur
if the catalyst is exposed to cleaning chemicals
containing phosphates, NaOH, silicates, Na and
Potassium Salts. These chemicals are found in most
commercial degreasers and cleaners; therefore, only
TurboChef® Oven Cleaner should be used.
CAUTION: Clean the catalytic converter with
TurboChef Oven Cleaner and rinse thoroughly
with distilled water. Let the catalytic converter
air dry before reinstalling. If TurboChef Oven
Cleaner is not available, use only distilled
water.
Air Filter
The filter is located on the back of the oven. It
helps prevent debris from getting into the electrical
compartment through the cooling fans. This
component requires daily rinsing and occasional
replacement, as it must be kept clean and in good
working condition to ensure proper air circulation
to the electrical components of the oven. See page
5, step 4 for details.
Troubleshooting
The following issues may occur in relation to the
filtering system:
• F9: CC Temp (if the catalyst is clogged with
grease and debris -see page 52).
• Fire in the cook cavity (if catalytic converter is
clogged and oven is not regularly cleaned).
• Electrical component failure (if filter is not
present or is clogged).
• Undesirable flavor transfer or odors.
