Perform the tightness test
After the program starts, the firing chamber is closed, heated and evacuated. When the
maximum vacuum is achieved, the prompt "Flood chamber?" appears. Monitor the pressure
display over approximately two minutes. A rise in pressure of about 20 mbar over two minutes
(10 mbar/min) is normal and means that the firing furnace is vacuum-tight. You can now click
[OK] in the "Flood chamber?" window. The firing chamber is ventilated and then opened.
When you observe a much higher rise in pressure: Clean and check all the components of the
vacuum system (replace the seals and hoses if necessary), and repeat the tightness test.
NOTE:
Always coat the sealing ring on the lift seat (O-ring) with talcum powder after cleaning so
that the lift seat does not hold to the firing furnace housing.

Before transporting:
•
