Assembly
4.1 Installation Guidelines
•
Direct installation under distributor or water tap with
discharge connection downwards
•
Backflow preventers of this type have an integral
strainer which protects the device from the ingress of
dirt. With highly polluted water a fine filter should be
installed upstream to ensure the correct function of
the device
•
The installation location should be protected against
frost. For use on outside taps, the backflow preventer
has to be dismounted if there may be danger of frost
•
In order to avoid flooding, it is recommended to
arrange a permanent, professionally dimensioned
wastewater connection
•
These armatures need to be maintained regularly
