8. Maintenance
Drinking water is a foodstuff. Regular monitoring
and hygienic care when implementing any work
should be a matter of course. Regular refill replace
-
ment and maintenance is necessary to ensure the
functionality of the unit (the unit will indicate when
a refill replacement is required). Maintenance, re
-
fill replacement and service works must be imple-
mented by trained experts in compliance with the
drinking water regulations. The system operator is
also required to carry out a visual inspection of the
system at regular intervals (every 2 or 3 days).
This should concentrate on any installation leaks
and the functionality of the unit:
- Check the hydraulic installation
- Check the electrical installation
- Check the display on the control unit
