Plug the the other end of the molex cable into the
USB board as shown in Figure 5.5. Ensure that,
when facing the oven, the red stripe is on your left
and the two empty sockets are on your right.
NOTE:  e picture below shows the molex cable
not completely inserted, ensure you completely
insert the molex cable.
Wiring Harness
 e wire harness distributes power to the oven’s
electrical components. See section 7 for schematics.
Exhaust System
 is section contains information about the
following components:
- Catalytic converter
- Exhaust Blower
- Vent catalyst
Catalytic Converter
 e catalyst functions by substantially lowering
the combustion temperature of grease entrained in
the air path to approximately the same temperature
of the airfl ow; thus the grease burns and breaks
down into CO
2
and H
2
O as it passes through the
catalytic converter.  e catalyst will operate most
effi ciently at temperatures above 475°F (246°C).
 e 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.  ese chemicals are found in most
commercial degreasers and cleaners; therefore, only
the self-clean feature should be used.
CAUTION:  e catalytic converter can be
cleaned with TurboChef
®
oven cleaner and rinsed
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.
Exhaust Blower
 e exhaust blower is located in the bottom rear of
the single wall oven. It’s purpose is to vent the hot
air from the electrical compartment.
Vent Catalyst
In addition to the main catalytic converter, the
Speedcook oven contains an additional catalyst in
the vent tube path.  is catalyst further assists in the
breakdown of grease and particulate matter before
the excess air enters the atmosphere.
