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.
Changes in the water quality may have to be made in the settings.
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 prerequisite for function and warranty is the
replacement of wear parts at the prescribed intervals.
9.1

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.
9.2

Controls

(by the operator)
BWT recommends that the operator regularly carries out and logs the
following checks:
● Water pressure: If the pressure conditions change, the product set-
tings may also have to be changed.
● Operating condition of the product (soiling).
● Checks whether (error) messages have been issued.
● Tightness.
