Operating the Sliding Sash
The counterbalanced, anti-racking sash mechanism requires only a few pounds of force
to move the sash up or down. You can open or close the sash smoothly with one or two
hands positioned on either handle.
The sash position alarm and safety interlock system senses the sash position and acts
appropriately. The biosafety cabinet has been programmed to operate at either an 8- or
10-inch (203-,250- mm) sash opening, depending on model. Raising the sash above its
operating height will activate the audible and visual alarms. The audible alarm can be
temporarily muted (for approximately five minutes) by depressing and releasing the
OK/Mute button. Closing the sash back to its operating position will reset the alarm
and defeat the muting of the alarm. The safety interlock system senses when the sash is
closed and allows the optional ultraviolet (UV) lamp to operate only when the sash is
closed, to protect the operator from irradiation.
Starting the Biosafety Cabinet
1. To start the biosafety cabinet, raise the sash until its bottom edge aligns with the
proper sash height label on the left corner post, as decal is shown in Figure 4-5.
2. Press the blower button to start the unit. The unit will display a standby screen
for approximately 60 seconds to allow the cabinet to reach proper operating
conditions. If the alarm sounds, recheck the sash position. If the sash is too
high, the sash audible alarm and the LCD display will indicate the sash is too
high.
3. To turn the UV light on, the sash must be completely closed to prevent the
escape of any UV radiation. Push the UV light button to activate the UV light.
Note: The sash must be completely closed for the UV light to activate.
