3. Where practical, place everything required inside the fume cupboard before commencing
process.
The design of the cupboard is for the sash opening to be at a maximum normal working
height of 450mm from the top of the lower sash. To increase the levels of safety it is
good practice to keep the sash in the closed position as much as possible.
Should you require the sash above the 450mm height (i.e. for setting up equipment) the
sash stop button (Fig3 item 4) needs to be pulled out to allow the sash to be raised
above the maximum safe sash height. If the Fume Cupboard is operated with the sash
above 450mm a flashing amber light and buzzer will sound, and the display will alternate
between “Sash High” and the face velocity to warn that containment levels and airflow
velocities are compromised. Pressing the “ENTER” button can mute the alarm. The alarm
will reactivate after a time of approximately 5 minutes if sash has not been moved back
to normal operating height.
4. Position apparatus and materials in the fume cupboard so as to minimise disturbance to
the airflow at the working aperture and it is possible to quickly close the sash without
any risk of disturbing apparatus.
5. Always use appropriate PPE (personal protection equipment) when using the Airone XP
Fume Cupboard.
6. Always close the sash when leaving the fume cupboard unattended.
7. After use, follow the correct procedures for disposal of any residues and leave the fume
cupboard in a safe state for further use by others.
