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.

10 Warranty
If the product malfunctions during the warranty period, please contact
your contract partner, the installation company, and indicate the mo-
del type and production number (see specifications or the type plate
on the unit).
Non-compliance with the installation conditions and the operator respon-
sibilities voids the warranty.
The wearing parts defined in the “Operator responsibilities” section and
the consequences of failing to replace these parts on time are not co-
vered by the 2-year legal warranty.
BWT assumes no liability in the event that the unit fails or if the capa-
city becomes deficient due to incorrect material selection/combination,
floating corrosion products or iron and manganese deposits, or any re-
sulting damage thereof.
The use of regenerative that does not comply with DIN EN 973 type A
voids the warranty.
9.2 Maintenance
The replacement of wearing parts within the prescribed maintenance
intervals is also required for the warranty and proper functioning of the
unit. The unit must be serviced once a year. Communal units must be
serviced twice a year.
We recommend that you enter into a maintenance agreement with your
fitter or the after-sales service department.
