following components:

- Air filter

V
ent catalyst
C
atalytic 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 temperatur
e of gr
ease entrained in
the air path to approximately the same temperature
of the air
flo
w; thus the grease burns and breaks
do
wn into CO
2
and H
2
O as it passes thr
ough the
catalytic conv
er
ter. The catalyst will operate most
efficiently at temperatur
es above 475
º
F (246
º
C).
The catalyst material is v
ery sensitive to certain
chemical compounds. I
rreversible damage can
occur if the catalyst is exposed to cleaning
chemicals containing phosphates, N
aOH, silicates,
Na and Potassium Salts. These chemicals are found
in most commercial degreasers and cleaners;
ther
efor
e, only TurboChef
®
Ov
en Cleaner should
be used.
CAUTION: Clean the catalytic converter
with
TurboChef Oven Cleaner and rinse
thor
oughly with distilled water. Let the
catalytic conv
erter 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 r
equir
es scheduled maintenance and
occasional replacement, as it must be kept clean
and in good wor
king condition to ensur
e proper
air circulation to the electrical components of the
o
ven. See page 5, step 4 for details.
V
en
t Catalyst
In addition to the main catalytic converter, the
NGO oven contains a secondary catalyst in the
v
ent tube path.
This catalyst further assists in the
breakdown of grease and particulate matter before
the ex
cess air enters the atmospher
e.
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 38)
- Fire in the cook cavity (if catalytic converter is
clogged and oven is not regularly cleaned).
- Electrical component failure (if filter is not
pr
esent or is clogged).
- Undesirable flavor transfer.
-
Undesirable odor emissions.
