
Sash safety pin must always be in place when the sash is in normal operating height. Only remove the
left and right safety pin if the sash is going to be lowered.

The sash window should be fully closed when the cabinet is not in use. This helps keep the work zone
interior clean.

The sash window should always be in the normal operating height at all times when the cabinet is in
use. Even if the cabinet is left unattended, but the blower is on, the sash window should never be
moved from the normal operating height, unless during loading or unloading of materials/apparatus
into the cabinet.

The alarm will be activated whenever the sash window is moved from the normal operating height.

Whenever the sash window is moved to the correct height from a higher or lower position, the light
will automatically be turned on as a signal to the user.

The sash window may be opened to its maximum position for the purpose of loading/unloading of
materials/apparatus into the cabinet. When the sash window is fully opened, the alarm sound may be
muted by pressing MUTE button but, will be automatically sounded again after 5 minutes to remind
the user that it is not safe to work in the cabinet and the light will be turned on to facilitate cleaning.
