EMI Filters
(Mains Filters)
*Note: JP model has
three filters. Using the
standard mains filter
for F2 and a larger
mains filter, fitted
above, for F1 & F3. The
third, standard size
filter, is located to the
left of the HV
transformer for the
VFD mains supply.
Filters unwanted
frequency noise from
interfering with various
circuits and
components in the
oven
For use on the main
supply feeding all
branch circuits.

Check for signs of
overheating or dis-
colouration.
Check for shorts to
ground from all Live
and Neutral terminals.
Check for steady
voltage (Live & Neutral)
to the filter.

Cooling Fan
*Note: JP model has a
different fan
Supplies fresh air into
the component
chamber to cool down
the electrical
