The quartz sleeve and sensor should be cleaned
after each replacement of the UV lamp. The reactor
should be cleaned when necessary.

way as for first commissioning. When you press the
RESET button (press for 10 sec.), directly after swit-
ching on, the day counter is reset to 365 and the
unit is newly initialized.
All alarm messages are also given acoustical. The acoustical signal can be
reset by pressing the RESET button.
