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.

6. GENERAL SAFETY INSTRUCTIONS

6.1. Operating instructions Controller

Please read the kiln control instruction manual carefully. The kiln is ready for operation after it has been connected
to the mains supply and the controller.

Biscuit firing 0.00
Glaze firing 0.00

6.2. Correct operation during firing

• Do not place flammable objects near the kiln.
• The kiln may only be used in a well-ventilated room. In order to guarantee safe operation, the kiln may be only
operated up to an environmental temperature of 40°C.
• The kiln must be placed in a free-standing position in the room. Make sure that the heat release is not blocked.
Do not place any objects on top of, or around, the kiln.
• Never open the kiln during operation or before it has cooled down completely. High temperatures are released and
might cause physical injury and material damage. The manufacturer of the kiln does not assume any liability in such
cases!
• When firing materials which release hazardous gases and fumes, an exhaust air system must be installed that directs
these into the open air.
• Never use your kiln for firing inflammable materials or food.
