Safety
•
Check for damage prior to installa-
tion.
•
Immediately have any malfunctions
in operation rectified by qualified
technical personnel.
Persons who, due to their physical, sen-
sory or mental abilities or their inexperi-
ence or lack of knowledge, are unable to
operate the device safely may not oper-
ate it without supervision or instruction
from a responsible person.
Regular backwashing of the device is
required to ensure safe drinking water
hygiene (see chapter 4.3.1).
The mains voltage must not be inter-
rupted (e.g. via a light switch). If the filter
is not permanently supplied with power,
backwashing or a warning in case of
faults is not possible.
Do not use household cleaning agents to
clean the outside of the device, but only
use clear water to avoid embrittlement of
the plastic.
The device may only be repaired by qual-
ified 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 escape of water resulting in water
damage to the building/home.
If the device is removed due to an inter-
ruption of operation:
•
Protect the flange surfaces against
damage to ensure proper sealing.
•
Protect the device from dirt so as not
to impair drinking water hygiene.
•
Store the device in a frost-free place
to prevent damage caused by freez-
ing water and leakage.
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.
