Heating elements

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 every 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!
In case of an emergency this will save you unnecessary delay and allow you to continue firing as quickly as possible.
8.1.3.

Empty firing

We recommend an empty firing (without furniture or goods) after every 20th firing. This will "clean" the heating
elements and at the same time the oxide layer can renew itself which will extend the service life of the elements.
8.2.

Cleaning

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.

Spare parts

When ordering spare parts please have your invoice of purchase to hand. This invoice provides all the relevant data
which will allow you to quickly order any spare parts.

Troubleshooting

9.1.

The controller cannot be switched on

⇒ Check if the controller has been connected to the switch cabinet of the kiln.
⇒ Check if the kiln is connected to the mains supply.
⇒ Check the micro-fuse on the switch cabinet of the kiln. This has a T 2A fuse.
⇒ Have your house mains supplies (plugs), fuses and the current consumption of your kiln checked by a
qualified electrician.
9.2.

The controller displays an error message

⇒ You will find the relevant explanation in your user's manual for the controller.
