3.2 Cleaning

The furnace may only be cleaned when it is cool, since there is a burn hazard. If the furnace head is closed, the
temperature in the firing chamber is indicated on the touch screen. Do not use any cleaning solutions.
For cleaning activities in the firing chamber or visual inspection of the heating elements, the service position must be
assumed (Care Programs menu / Service Position, see Chapter 2.2.4.7).
Disconnect power before cleaning.
The following parts have to be cleaned from time to time:
Item:
Cooling tray
Object tray in the firing chamber
Furnace head sealing and sealing surface
Furnace housing and furnace head
Membrane-sealed keypad and display
Air vents
*Never clean with compressed air!
Visual inspection of the firing chamber and the heating elements
The firing chamber and heating elements should be checked if restorations appear to be discoloured. For this purpose, the
service position must be assumed (see Chapter 2.2.4.7). No foreign objects or dirt particles must be present in the firing
chamber during the sintering, glazing or crystallization process. Contamination can occur, among other reasons, due to
chipping of the oxide layer and/or protective layer of the heating element surface.
This type of contamination may have an effect on the optical properties (discolouration) of the restoration.
If glass particles or fine glass dust is detected during the visual inspection, the firing chamber must be cleaned. If restorations
show any discolouration, the cleaning program must be conducted again and again until the oxide layer and/or protective
layer of the heating elements is once again intact. As soon as this is the case, the object tray in the firing chamber must be
replaced to prevent further discolouration.
If the heating elements come in contact with the insulation or are bent inwards in such a way that they touch the
insulation, After Sales Service must be contacted.
Cleaning of the firing chamber
Use a vacuum cleaner with HEPA filter to clean the firing chamber. Never clean with compressed air. After cleaning, a
cleaning program (see Chapter 2.2.4.7) must be conducted. The firing chamber must be empty for this purpose.
The heating elements must not be touched during cleaning, as they could be damaged.
