on the type plate. (→ Technical data)

2. Turn the locking ring counterclockwise as far as the stop.

– How to determine which UVC lamp of the respective lamp pair is defective (L1a/L1b or
L2a/L2b): Change one of the two UVC lamps and assemble the unit. If the system message
is still displayed, reinsert the UVC lamp and change the other UVC lamp. If the system mes-
sage is still displayed, both UVC lamps are defective.
