12.3 Replacement of the Lamp/UVC Lamp

Turn the instrument off with the automatic power fuse and pull the power plug, before replacing the lamp!

If the lamp is broken, it must be replaced by the technical service, as the replacement involves a high risk of injury. Beware of the metallic mercury in the UV lamp; handle it carefully and dispose of it properly.

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 are blinking alternately in control panel field 1, the UVC lamp must be replaced.

Instructions on how to replace the UVC lamp are provided together with the replacement lamp (spare part).
