Operating the Sliding Sash
The Purifier's 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 Purifier is designed to operate with either an 8- or 10-inch sash
opening, depending on model. The PuriCare Procedure Stations are designed to have
either a 10- or 12-inch sash opening. 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 Mute/OK 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, allows the optional
ultraviolet (UV) lamp to operate only when the sash is closed, to protect the operator
from irradiation.

Starting the Logic
1. To start the Purifier, raise the sash until its bottom edge aligns with the sash
position label on the left corner post. The decal is shown in Figure 4-3.
2. Press the blower button to start the unit. The unit will run a self-test for
approximately fifteen seconds. 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.
