With the introduction of the new 2018 design, the viewing glass on
the machine must only be replaced by trained specialist personnel or
by INDEX Service.
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 the outer pane (a) also
made of polycarbonate. 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 panes
are subject to natural aging and must be replaced at regular intervals.
After replacing the inner viewing glass, it must be sealed on the inside of the work
area door. It is necessary to provide a suitable sealant. The sealant Terostat 930 is
used at the factory for this purpose.
