1Remove the fluoro glass sheet. (Refer to “2 How
to shift fluoro glass sheet.”)
2Loosen the screw A of both electrodes with a
Philips screwdriver, and remove the terminal
covers. The illustration on the right describes
the electrode after the terminal cover is
removed.
3Loosen screw B of both electrodes to loosen the
tension of the heating element. It is not
necessary to remove the electrode covers.
4Insert a Philips screwdriver into the hole of the
electrode cover and loosen screw C. The heating
element can be removed.
5When mounting the new heating element, insert
each terminal between the electrode plate and
electrode plate spring. While pushing down the
terminal with your fingers so it stays in place,
tighten the screw C with a Philips screwdriver.
6Tighten the screw B loosened at the procedure 3
so the heating element is stretched tight. When
the screw B is not tightened enough, the heating
element will not be stretched tight enough,
which may result in damaging the heating
element.
7Fix the terminal covers to the electrodes with
screw A.
1Remove the fluoro glass sheet. (Refer to “2 How
to sift fluoro glass sheet.”)
2Loosen the screw B of both electrodes with a
Philips screwdriver, and remove the terminal
covers. The illustration on the right describes
the electrode after the terminal cover is
removed.
󱷦Lower heating element replacement
(for all models)
󱷦Upper heating element replacement

Caution Without loosening the screw B, the
heating element will be kept
stretched tight. Thus the heating
element terminal cannot be inserted
between the electrode plate and
plate spring.
