The yellow indicator light below the switch will light when the UV light is turned on. This unit is
also capable of regulating the amount of time the UV light stays on which is determined by the
operator. This function is very useful if the cabinet is to be left unattended for an extended period
of time. To enable the timer, make sure the viewscreen is fully closed and the UV lamp is off.
Depress the UV keypad switch and hold for 3 seconds. The alarm will pulse twice to signify that
the timer mode has been entered. Release the switch. Immediately after, each press and release of
the switch will program the timer to elapse one hour. (one pulse equals one hour, four pulses
equals four hours, ect.) If no pulse is detected from the operator after four seconds, the timer
begins to elapse automatically. The timer can be disabled at any time during or after the timing
sequence by pressing the UV keypad or opening the viewscreen.

Start-up Procedure
1.
If the cabinet has not been left running continuously, turn on the blower. An indicator light located
below the switch will illuminate when the switch is on and the running blower will make an audible
sound. Check the readings on the Magnehelic gauge, it should read a pressure consistent with the last
time the cabinet was on.
2.
Turn on the fluorescent light. The fluorescent light will not operate unless the UV light is turned off.
Never leave the UV light on while there is anyone in the room, unless viewscreen is fully closed.
3.
Check to determine that the drain valve is in the closed position or the drain coupling is capped.
4.
Wipe down the interior area of the cabinet with a surface disinfectant.

thoroughly clean the surfaces afterward with a detergent and rinse with sterile water to
prevent corrosion.
5.
Place all materials to be used for the next procedure inside the cabinet on the solid worksurface.
Disinfect the exterior of these materials prior to placing them on the worksurface.
Everything
required (and nothing more) should be placed in the cabinet before beginning work so that nothing
