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
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.
