- Replacing the viewing glass
Orientation
If the viewing glass is damaged, it must be replaced. This is
necessary regardless of the extent of damage. Even with minimal
damage, the impact resistance of the glass can no longer be
guaranteed.
For safety reasons, it is recommended to obtain the viewing glass
directly from the machine manufacturer.
The viewing glass consists of three panes. the inner pane (i) made of tempered
glass, the central pane (m) made of polycarbonate, and an outer pane (a) made of
PMMA (polymethyl metacrylate). The inner pane (i) is relatively resistant. It can be
cleaned with any commercially available cleaning agents. Only the center pane (m)
is essential for the impact resistance of the viewing glass. The polycarbonate pane
is subject to natural aging and must therefore be replaced at regular intervals.
After replacing the inner viewing glass and after the installation activities are
complete, the glass it must be sealed on the inside of the work area door (S). It is
necessary to provide a suitable sealant. The sealant Terostat 930 is used at the
factory for this purpose.

If sealing compounds from other manufacturers are used, their
equivalence must be guaranteed by the supplier or manufacturer in
writing.
