Operator responsibilities
You have purchased a product that is durable and
easy to service. However, all technical equipment
requires regular servicing to guarantee optimal
functionality.
Regular checks of the filter by the operator are
required to ensure the warranty conditions and
proper functioning of the unit.
The operator must perform a visual check and
backwash the filter to guarantee functionality and
fulfil the warranty conditions. Additionally for HWS:
Check the output pressure every 2 months when
there is no flow and when large quantities of water
are drawn off.
According to DIN EN 806-5, the filter must be
checked for leaks and dirt every six months and
backwashed at regular intervals, which may depend
on operating conditions but be no longer than six
months.
