DANGERS DUE TO NON-COMPLIANCE
In detail, failure to observe the general danger symbols can result, for example, in the following risks:
/
Failure of important functions of the backwashing filter
/
Danger to persons due to electrical and mechanical effects
/
Danger to persons and the environment due to leaks
Refrain from any unsafe working methods.
Failure to comply with these operating instructions and the safety information can not only result in dan-
gers for persons but can also harm the environment and the unit.

WATER PRESSURE
The water pressure should be between 1.5 bar and 10 bar. The water pressure must not drop below
1.5 bar as otherwise the backwashing can be impaired! If the filter is not backwashed regularly
a pressure loss can result and this can impair the filter function.
In the event of water pressure above 10 bar, a pressure reduction valve should be
fitted upstream of the filter (see fig. 3). If the operating pressure is above 10 bar,
this may result in defects during operation.

For water pressures between 5 bar and 10 bar, the installation of a pressure reduc-
tion valve downstream of the filter is recommended.
