impair the backwashing function mechani-
cally.
According to DIN EN 13443-1 backwashing
the device is required at the latest every six
months.
The manufacturer requires a backwash-
ing:
•
at least every 2 months
•
if the water pressure drops
•
if the filter is visibly dirty
Experience has shown that new installa-
tions in the early stages of installation lead
to increased dirt deposits. In this case, a
more frequent backwashing is necessary.
4.2.2 Backwashing
WARNING
Persons who, due to their phys-
ical, sensory or mental abilities
or their inexperience or lack of
knowledge, are unable to operate
the device safely may not operate
it without supervision or instruc-
tion from a responsible person.
Before carrying out a backwash,
ensure that the wastewater con-
nection is functional.
At the end of the backwashing
process, turn the handwheel until
it engages so that no more back-
wash water escapes. Otherwise,
water may constantly escape and
cause water damage.
1.
Turn the handwheel in any direction by a
full turn.
Backwashing water escapes.
2.
Turn the handwheel until it clicks into
place. Ensure that no water escapes.
The backwashing process is completed
(see chapter 4.2).
4.3
Conversions, changes
WARNING
Unauthorised conversions and
changes are forbidden for safety
reasons. These can impair the
functioning of the device, leading
to leaks and, in the worse case
scenario, to bursting of the device.
4.4
Maintenance, repair,
spare parts
WARNING
The device may only be repaired
by qualified technical personnel.
Only use original spare parts for
repairs.
Before performing work on the
device that goes beyond pure
operational use, the device
must be depressurised! If this is
ignored, the result may be uncon-
trolled egress of water result-
ing in water damage to the build-
ing/home.
