10 Cleaning the furnace
Before each cleaning operation, remove the power supply plug!
It is not necessary to clean the inside of the firing chamber. Cleaning the casing
of the firing chamber at regular intervals with a damp cloth contributes to its
operating safety.
In all cleaning work, you must never use any detergents or flammable
liquids.
10.1 Cleaning firing for the firing chamber
Consult the operating manual of the corresponding control unit for information
about the cleaning firing.
10.2 Firing chamber insulation
The firing chamber contains insulating material comprised of ceramic mineral
fibers (index no. 650-017-00-08) that have been classified as category 2
carcinogens (Annex VI, EC 1272/2008).
When working with the firing chamber or exchanging the firing muffle,
fiber dust may be discharged.
Exposure to this dust can potentially be carcinogenic on inhalation,
as well as result in irritation of the skin, eyes and respiratory organs.
When exchanging the firing muffle, proceed as follows:
• Long-sleeved protective clothing
• Wear safety goggles as well as protective gloves
• Use a dust vacuum system or wear a FFP 2 respirator
Once work has been completed, rinse dust from unprotected skin using
cold water. Wash workwear separately from everyday clothing.
11 CE mark
With the CE mark, a legally binding declaration is made to the effect that the
device corresponds to the fundamental requirements of European Community
Directive 2006/95/EC (Low-Voltage Directive) and European Community
Directive 2004/108/EC/EWG (EMC Directive).
12 Fan
The device is equipped with a fan.
Activation, deactivation and speed of the fan are controlled automatically.
The fan prevents excessive heating of the device and contributes to its general
operating safety. If the fan fails, an error message is shown on the display.
(For information about this, refer to the Error Messages section of the control
unit’s operating manual.) For safety reasons, the device must not be operated
without a fan. The upper cover of the firing chamber and the openings in the
rear cover must not be closed or blocked.
