36 OVEN SYSTEMS
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 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, 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.
