9 Operator responsibilities

You have purchased a durable and service-friendly product.
However, all technical equipment requires regular servicing to guaran-
tee optimal functioning.
Regular checks performed by the operator are required for the warran-
ty and proper functioning of the unit. The unit must be inspected regu-
larly or, at the latest, every 2 months depending on service and opera-
ting conditions.
On a regular basis, find out about the quality/pressure ratio of the wa-
ter to be treated. If the water quality changes, the settings may need to
be changed. Consult a specialist if this is the case.
