OPERATING INSTRUCTIONS
(CONTINUED)
8.
Try to place everything required for your process inside the fume cupboard prior
to starting any operation. This will reduce the amount of arm movements into and
out of the fume cupboard and hence reduce possibility of breakout (fume escape).
9.
Position apparatus inside the fume cupboard so that disturbance to airflow at the
sash opening is minimised.
10.
After use follow the correct procedure for disposal of any residues and leave the
fume cupboard in a safe state for further use by others.
11.
Before switching off the cabinet after use, allow it to run for a further 5 to 10 minutes
to make sure all hazardous vapours or gasses have cleared, and check that any
bottle are capped or stoppered and no material has been left on the necks or
pooled around the bases.
Good housekeeping is essential to prolong carbon filter life.

In normal operation, the arrows will be lit with green LEDs. If these turn red and the
audible alarm sounds, it will indicate that the filter is potentially saturated or a
breakthrough has occurred.
