STOPPAGES
If a backwashing filter has to be removed from the flange or unscrewed, the following
notes must absolutely be observed:
/
Protect the flange surfaces from damage! Damaged flange surfaces cannot close tight any longer. As a
result, escaping water can damage the building and installations.
/
Ensure that no dirt can get into the backwashing filter! This dirt can get into contact with and be dis-
charged into the drinking water when the backwashing filter is switched back on. The health of persons
who drink dirty water is at risk.
/
Store the backwashing filter in frost-free conditions! Frost can cause any water contained in the back-
washing filter's voids to freeze and thus cause mechanical damage to the backwashing filter so that it
leaks at operating pressure or can burst. Leaking water can cause major damage to the building. In ad-
dition, persons near the backwashing filter can be injured by breaking off filter parts.
/
When restarting the backwashing filter, follow the instructions for a new backwashing filter.
