button on the controller to turn off the unit. The LCD screen will display the time and date.
6) Clean the unit on a scheduled basis. See MAINTENANCE section for instructions. (page 18)
The alarms that are built into the system are maintenance related. They are designed to tell
the operator about conditions that may affect the operation of the workstation and decrease its
performance.
• ALARM UV CHECK -
The UV light alarm occurs after 900 use-hours of the UV bulb.
(One use-hour = an hour of actual use or one on/off cycle of the light.) After 1000 use-hours,
the UV bulb may glow blue but the UV radiation may not be effective. Replacement of the
UV bulb is required.
