7.5 Notes on cleaning the unit components
Unit component What to clean and how to clean
Steam tank / steam tank strainer
• Carefully brush off any limescale from the components
(do not use a wire brush).
If the components are heavily calcied, place them in
an 8% formic acid solution (observe safety notes in
chapter 7.6), until the limescale comes off.
• Wash components with a lukewarm soap solution, then
rinse well with tap water.
Steam tank cover and
Heatingelements
• Immerse cover with heating elements tted to 2 cm
below the rim of the cover in a container with 8% formic
acid (observe safety notes in chapter 7.6). Allow the
acid to take effect until the scale coating on the heating
elements has dissolved.
Note: The heating elements do not have to be entirely
free from scale.
• Rinse heating elements thoroughly with fresh water.
CAUTION! Ensure that the electrical connections re-
main dry.
CAUTION! On no account remove scale coating on the
heating elements with tools (screwdriver, scraper, etc.)
or by striking. This could damage the heating elements.
• Carefully remove any limescale underneath the cover
and on the thermostat(s) with a soft bristled brush (do
not use a wire brush). The thermostat must be free of
limescale.
Hoses
• Remove any limescale in the hoses by carefully twisting
and the hoses. Then, rinse the tubes well with hot tap
water.
