5.8. Mounting the controller on the wall

Mounting the controller TC 304
Choose a safe and easily accessible place 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 fasten the controller in the fixing device�
Mount the holding bar of the control unit TC 304 using the 3 dowels and 3 screws, so that one fixing hole points
upwards and the other two point 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 place 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 and 2 screws� Now the control unit can be plugged into the fixing
device from above�

5.9. Kiln and furniture initial firing

CAUTION: First remove the protective foil from the entire kiln (floor rings and cover)!!!
Before starting to use the kiln in every day firing, you must carry out a dry firing� For this purpose make sure the ex-
haust air opening on the side of the kiln is open� The "burning-in" by means of a dry firing is important, in order to
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 air supply 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 7�3�
After the first firing, the belts around the cover and the main ring must be retightened� For further information please
see section 8�0�
5.10. Instructions power connection / Residual current protective device (RCD)
If you intend to operate the kiln 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 suggest 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�
