Example For Positioning Furniture Plates; Maintenance / Care And Cleaning; General Maintenance Instructions - Rohde KE L Serie Manual De Instrucciones

6.3. Example for positioning furniture plates

Place the 3 cordierite blocks forming a triangle on the floor of the kiln, then place one of the furniture plates (optional
accessory) on top� Please note that all plates and stilts must be burnt-in (see section 5�11�)� Do not place the plates
too close to the heating elements as this might cause the plates to crack� The distance to the heating element should
be at least 20 mm�
We suggest that the furniture plates are supported in 3 points – for 2-piece furniture plates 3 stilts per plate – and that
the stilts are positioned one on top of the other for each layer� Otherwise the plates might be exposed to stress from
bending which could result in deformation or cracking�

7. MAINTENANCE / CARE AND CLEANING

7.1. General maintenance instructions

Safety check in accordance with DGUV regulation 3: When operated industrially, the kiln and controller must
undergo a safety check to ensure correct functionality� This should be carried out by a qualified electrician before the
initial operation and then at 4-year intervals in accordance with DGUV regulation 3 (Accident prevention regulation
for Electrical installations and equipment by the German professional association)�
Maintenance and repair: Maintenance and repair of electronic components must be carried out by a qualified
electrician� For safety reasons the kiln must be disconnected from the mains supply before any maintenance work is
carried out�
Please make sure that no clays and glazes come into contact with the heating elements� This will cause the heating
elements to malfunction during subsequent firings� If, however, impurities get onto the heating elements, clean them
immediately, as burned-in glazes etc� will damage the heating elements and bricks� If there is substantial damage,
please contact Helmut Rohde GmbH or your retailer�
Heating elements are subject to wear� Their resistance (Ohm) increases with each firing� Over the course of time this
will lead to delays in the firing cycle due to a drop in performance, especially in the upper temperature range� If there
is excessive wear we recommend that you replace the complete set of heating elements rather than just single
elements� Replacing individual elements might lead to variations in temperature inside the kiln�
Have a qualified electrician replace the heating elements!
A tip for the firing professional: Always keep a spare set of heating elements! Should an emergency arise,
this will save you unnecessary delay and allow you to continue firing as quickly as possible.
Remove clay and stone dust regularly using a broom and a vacuum cleaner� This will also increase the service life of
your heating elements�
Avoid reduction glaze firing, as this will cause the oxidation layer to decompose, thus significantly reducing the service
life of the heating elements� We recommend an empty firing after every 20th firing� This will "clean" the heating elements
allowing the oxide layer to renew itself and will extend the service life of the elements�
