4.2 Sash
Always keep the sash closed during tests and if not in operation. The sash should only be opened during the
test set up. For short-term access always use the cross slides. The fume cupboard may be manually operated
at any time, irrespective of an optional sash control. The sash may be horizontally opened and closed by the
loop handle. When opening the sash it should be opened up to the stopper that stops the sash at an opening
height of 500 mm (normal operation). Beyond, the sash may only be opened by turning the loop handle. The
sash should be opened beyond 500 mm only during the test set-up. As soon as the sash is pulled down it is
automatically locked below the 500 mm marking.
