the kiln, malfunction and impairment of the protective functions of the kiln.

Cleaning advice:
• Clean the kiln regularly - at least once a week.
• Make sure that no foreign substances or impurities get onto the insulating firebricks and heating elements.
• Otherwise, this inevitably leads to damage to the insulating firebricks and heating elements or failure of the
heating elements during the subsequent firings.
• If the insulating firebricks and heating elements do become contaminated, remove them immediately, as burnt-in
foreign matter will damage them.
• Remove loose particles with a clean broom or industrial vacuum cleaner. Use a vacuum cleaner with the
appropriate filter class.
• When cleaning the firing chamber with a broom or vacuum cleaner, avoid touching the remaining heating
elements.
• Do not use compressed air.
• Remove other contamination with a clean, dry cloth.
• Do not use detergents or water.
• Never wet clean or hose down the inside of the kiln.
• In the event of extensive areas of burn-in on the kiln insulation or other major damage, contact the local specialist
or the manufacturer.
Possible consequences are damage to the components of the kiln, malfunction and
impairment of the protective functions of the kiln.
Always clean the kiln dry, and without water or compressed air.
Do not use compressed air to clean the kiln or switch cabinets!
Do not clean electrical circuits or equipment with compressed air!
