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 1.5 Maintenance in order to clean the
clogged filtering elements again. To hold the
back-flushing cycles automatically the filter
can be fitted with a back-flushing automatic
(Fig. 712 99). The premise for the function
of the back-flushing automatic is an electric
current supply (230 V AC) at the assembly
area and a close installed, sufficiently dimen
-
sioned waste water connection.
Mounting
The Filter Module F Figure 712 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. In order to gua-
rantee a problem-free, purposeful operation,
the filter has to be mounted vertically in all
cases, with the outlet pointing downwards.
This is the only way to guarantee that the
drain funnel will work properly. The filter
outlet designed according to DIN EN 1717 is
to be connected to sewerage if waste-water
piping is available.
If the backwash water is drained into a floor
drain, make sure that the backwash water
volume can be transported off at all times.
No remnant water volume is permitted to
remain in the room.
The pipe has to be flushed before the com
-
missioning of the filter.
Note!
The drain line has to have sufficient capacity.
This is designed according to DIN 1986-100
in conjunction with DIN EN 752 and DIN EN
12056. An incorrectly designed drain line can
lead to a malfunction of the drain.
