9.3.3 Replacing the UVC lamp
Switch the instrument off and disconnect the power plug before replacing the fluorescent
lamp! Wear suitable safety gloves and safety glasses.
If the lamp is broken, it must be replaced by the technical service, as the replacement involves
a high risk of injury.
A UVC lamp has an estimated service life of approx. 9,000 hours.
Each on/off switching cycle reduces the lamp life by approx. one hour plus
burning time (30 minutes or 180 minutes respectively).
When both disinfection indicator lights (short and long-term dis-
infection) are flashing alternately in control panel field 1, the UVC
lamp must be replaced.

go.
