Operation
5.12 Conversions / changes / spare
parts
Only original spare parts may be used!
Unauthorised conversions and changes are
forbidden for safety reasons! Such actions
could impair the functioning of the water sof-
tening system. The imprinted approval
marks are only valid if original spare parts
are used.
5.13 Maintenance/repair
NOTICE
Before performing work on the water sof-
tening system that goes beyond pure oper-
ational use, the water softening system
must be depressurised!
If this is ignored, the result may be uncon-
trolled egress of water resulting in water
damage to the building/home. Therefore the
instructions given in chapter 4 “Installation”
and chapter 7 “Servicing” must be strictly
observed.
5.14 Interruption of operation
The water supply to the water softening sys-
tem is interrupted. The main stopcock is
closed or the bypass valve is switched over.
– When disassembled, the water softening
system must be stored in a dry and frost-
free location.
– The connection flange must be protect-
ed against dirt and damage.
– Once the water softening system is fitted
and started again, it must be flushed and
regenerated (see chapter 5.4 “Start of
operation”).
