Filtering System
This section contains information about the
following components:
- Catalytic converter
- Drain pan
- Air Filter
- Vent catalyst
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 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 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, do not use a
substitute. Use distilled water only.
Drain Pan
The drain pan collects debris as it is flushed
through the bottom of the cook cavity.
Air Filter
The filter is located on the back of the oven. It
helps prevent debris from getting into the electrical
compartment.
Vent Catalyst
In addition to the main catalytic converter, the i5
oven contains an additional catalyst in the vent
tube path. This catalyst further assists in the
breakdown of grease and particulate matter before
the excess air enters the atmosphere.
Troubleshooting
The following issues may occur in relation to the
filtering system:
- 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.
- Undesirable odor emissions.
