5.3.1 Backwashing interval
The Backwash Protective Filter must be
backwashed:
– Every two months at the latest.
– If the water pressure falls.
– If the backwash protective filter is visibly
dirty.
There is a display button on the built-
in rotary flange attached to the back-
wash protective filter. It can be slid
along the months scale. This enables
the backwashing interval to be moni-
tored.
ATTENTION
(see
chapter
"Safety
dangers due to non-compliance")
If the interval until the next backwashing is
longer than two months, the particles on the
filter screen can stick or a large filter pres-
sure resistance can result.
Unauthorised persons must not operate the
filter! Persons who operate the filter must
observe the operating instructions. Failure
to observe these instructions can result in
damage to property and personal injuries.
The smaller the mesh size of the screen
insert the more frequently backwashing is
required!
From experience, increased dirt is deposited
during the initial running period. In this case
the unit will have to be flushed more
frequently than normal.
Failure to flush in good time can cause dam-
age to the screen. Large quantities of filtered
particles can deform the screen. As a result,
proper function of the filter is no longer en-
sured. In addition, large quantities of dirt can
cause mechanical damage to the back-
washing function.

Modifications / changes /
spare parts
ATTENTION
(see
chapter
"Safety
dangers due to non-compliance")
Only original spare parts are to be used!
Independent modifications and changes are
prohibited for safety reasons! These can
impair the function of the filter, lead to lead
and in extreme cases can cause the filter to
burst.
The test marks imprinted on the unit are only
valid if original spare parts are used.
5.4.1 Servicing / Repair
Before carrying out any work on the filter,
which extends beyond pure operational con-
trol, the filter must be depressurised! Failure
to observe this can lead to an uncontrolled
escape of water and therefore lead to water
damage in the building. Strictly comply with
the instructions given in the "Installation"
and "Maintenance" chapters.
