10 Operator's responsibilities

You have purchased a durable and service-friendly product. However,
this also entails obligations. For a perfect function you must ensure:
● Intended operation.
● Regular inspections and service work.
In case of changes in water quality or flow rates, the limits of use of the
system must be checked.Prerequisites for the function and safety of
the product are inspections, regular inspections (every 2 months) by
the operator and a half-yearly (every 6 months) routine maintenance
(EN 806-5) of the entire drinking water installation. A further prerequi-
site for function and warranty is the replacement of wear parts at the
prescribed intervals.

10.1 Intended operation

The intended operation of the product includes commissioning, ope-
ration, decommissioning and, if necessary, recommissioning. Proper
operation of the product and the drinking water installation requires
regular checks, servicing and operation in compliance with the operating
conditions used for planning and installation.

10.2 Inspections

(by the operator)
BWT recommends that the operator regularly carries out and logs the
following checks:
Water pressure:
If the pressure conditions change, the limits of use of the system must
be checked.
Water quality:
If the water quality changes (UV transmission), the operating limits of
the system must be checked.
Flow rate:
If the flow rate (l/min) changes, the operting limits of the system must
be checked.
Operating status of the product:
Checking whether error messages were issued
Tightness:
Checking whether water escapes from the system
Contamination and calcification:
Check whether foreign particles or deposits influence the proper ope-
ration of the device
Condition of the device:
Check whether there is damage and whether all parts are in the inten-
ded place

11 Warranty

If the product malfunctions during the warranty period, contact your
contract partner, the installation company, and quote the unit type and
production number (see Technical specifications or the type plate on
the unit).
Non-compliance with the installation conditions and the operator
responsibilities voids the warranty and disclaims liability.
The wearing parts defined in the "Operator responsibilities" section
and the consequences of failing to replace these parts on time are not
covered 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
resulting damage thereof.
