5.10. Mount the controller
Mounting the controller on the kiln
Place the panel for mounting the controller (optional accessory KE-L series) in a posi-
tion that will allow the star-shaped knob to be turned until it locks into the position
indicated (figure 14)�
When the panel is fixed, you can start mounting the controller on the panel� You will
find a detailed explanation in your user's manual for the controller�
Mounting the TC 304 controller on the wall figure 14
Choose a safe and easily accessible position on a wall next to the kiln� First screw the two knurled screws into the
holes indicated on the back of the control unit� They will be used later to fix the controller in the fixing device� Mount
the holding bar of the TC 304 control unit using the 3 dowels and 3 screws, with one fixing hole pointing upwards and
the other two pointing downwards� Make sure that the transparent protective foil is correctly aligned!
Now the control unit can be plugged into the fixing device from above� You might have to loosen the knurled screws
on the controller�
Mounting other TC controllers
Choose a safe and easily accessible position on a wall next to the kiln� Detach the wall fixing device from the TC
control unit� Mount the fixing device on to the wall using 2 dowels and 2 screws� Now the control unit can be plugged
into the fixing device from above�
5.11. Kiln and furniture initial firing
CAUTION: First remove the cardboard, protective foil, etc. which were used to protect the kiln!!!
Before doing this, make sure the exhaust air opening and air supply are open� The "burning-in" by means of a dry
firing is important, as this will remove residual moisture from the kiln walls� It also generates a protective oxide layer
on the heating elements which will considerably improve the service life of these components�
Settings for initial firing:
• Heat up at 100°C / h
• End temperature 1050° C
• Holding time 1 h 30 min�
Please note that the service life of the heating elements can be significantly increased by opening the exhaust air up
to a temperature of 600-700°C� During the initial firing you can also "burn-in" the hollow stilts and additional furniture
plates (optional accessories)� For further information please see section 6�3�
5.12. Instructions power connection / Residual current protective device (RCD)
If the kiln is to be operated in workshops or laboratories, a separate power supply with fuse protection must be installed
by a qualified electrician� Residual current protective devices (RCD) carrying a tripping current of 0�03 A (such as that
used in damp rooms in flats) tend to trip early due to the high humidity of the rooms or fired goods�
A larger sized RCD can be selected (we recommend 0�3 A) provided that the respective circuit is used only for the
kiln� If this cannot be guaranteed, a fixed power connection must be provided�
