Maintenance
Regular servicing of the system ensures that the quality of the treated water will remain constant.
To ensure that your system is serviced properly we recommend that you obtain a maintenance
contract with a service company authorized by the manufacturer. You can then be certain that
your system will have a high degree of operational reliability and dependability.
To ensure that your system functions without any errors it must be checked, maintained and
serviced at regular intervals, as described in these operating instructions. The operating
instructions must therefore be kept in an easily accessible location for anyone who is using or
servicing the system.
Calibration of the conductivity may only be performed by a service technician authorized by the
manufacturer.
Cleaning of the system should be performed annually. Cleaning must also be performed in the
event of a high bacteria content or impurities in the product water and when changing the
ultrapure cartridge.
DANGER

Maintenance Intervals
Wear parts must be replaced in accordance with the following table. The intervals have been
