• Knock off or brush away any limescale as much as pos-
sible (do not use a wire brush).
If the parts are heavily calcified, place them in an %
formic acid solution (
observe safety notes in chap-
ter 7.5
), until the limescale comes off.
• Finally wash parts in a lukewarm soap solution and rinse
well with tap water.
Heating electrodes
• Immerse the heating electrodes (up to 2 cm below the
snap fastening) in a container with -percent formic acid
(
observe safety notes in chapter 7.5
). Allow the acid
to take effect until the limescale has dissolved.
Note: The heating elements do not have to be entirely
free from scale.
• Finally rinse the heating electrodes well with tap water
and let them dry.
CAUTION!
On no account remove limescale from
the heating electrodes using tools (screw-
driver, scraper, etc.) or by striking. This
could damage the heating elements.
Water hoses
• Remove any limescale by slightly knocking on the tubes
using a rubber hammer. Then, rinse the tubes well with
hot tap water.
