The pressure reducing valve-filter combinati

on Figure 713 0G is to be connected with the
basic module Figure 700 0G and stress-free
mounted into the piping. Attention has to
be paid to the flow direction marked on the
basic module.
The outlet at the filtering unit designed ac

cording to DIN EN 1717 is to be connected to
sewerage if waste-water piping is available.
Installation of a floor inlet within the range
of the filter is recommended in order to assu

re automatic flowing-off of the water arisen
at back-flushing.
Note!
In order to guarantee a problem-free, purpo-
seful operation, the filter has to be mounted
vertically in all cases, with the outlet pointing
downwards.
Operation
When the filter segments become clogged
the pressure difference over the filter increa

ses, which results in a noticeable reduction
of the rate of flow output. The high pressure
difference arisen is visible by projecting the
red indicating pin inside the transparent field
on the back-flushing indicator (A). The filter
has to be back-flushed according to point 2.5
Maintenance in order to clean the clogged
filtering elements again.
The filter can be equipped with an automatic
back-wash accessory (Figure 712 99) to
ensure the required periodic back-wash of
the filter for cleaning purposes. Therefore a
230V power supply and a drain connection
are required.
