The exhaust air flap closes during the firing operation when the kiln reaches the specified
closing temperature.

6.5.6. Programming the cooling system (ST 411 only)
NOTE
The introduction of cooling air using a blower or fan at a firing chamber temperature of more than
600°C can damage the insulating material or heating elements.
⇒ Cold air may only be brought in at a temperature below 600°C
.
⇒ The fan cooling system must never run during the firing process!
⇒ The cooling system is only switched on below 600°C when the kiln is in cooling mode and is
not being heated anymore!
⇒ The exhaust air opening must be open when a cooling blower or cooling fan is in operation.
⇒ Early cooling is not recommended as this can have a negative impact on the ceramics,
glazes and the durability of the kiln lining and the service life of the heating elements.
The manufacturer assumes no liability for damaged insulation material or heating elements if the
instructions have not been followed.
NOTE
The kiln must be prepared at the factory for the use of a cooling system with a blower or fan.
⇒ Retrofitting a cooling system with a blower or fan in a kiln without a cooling system is
generally not recommended.
⇒ Kilns with a cooling system are specially prepared and manufactured by the manufacturer for
use with a cooling system.
