5.2 Decommissioning
5.2.1
Short-term decommissioning (less than two weeks)
It is essential to wait until any ongoing regeneration has been completed. Otherwise, there is
a risk that hardness or even brine will be fed into the system during recommissioning.
Pull out the mains plug
Close the shut-off valves in the raw and soft water lines
If a supply to the downstream consumers is required, including a raw water supply, open the
bypass line (if available).
5.2.2
Long-term decommissioning (more than two weeks)
The softening system (both filters) must be completely regenerated before it is decommissioned
for a longer period of time.
To trigger a regeneration, press the REGEN button for at least 3 s (the first of the two filters
is now regenerated) and wait for it to be completed.
Wait at least 5 hours (at min. 15°C) until new brine has formed in the brine tank
Trigger another regeneration by pressing the REGEN button for at least 3 s
(the second of the two filters is now regenerated) and wait for it to be completed.
After regeneration has been completed, pull the mains plug out of the socket.
If the softening system is at risk of frost during the decommissioning period, the water
must be removed from the filter. The residual moisture in the filter is sufficient to prevent
the resin from drying out. In this state, the resin can tolerate frost down to –10°C without
being damaged.
5.2.3
Recommissioning
5.2.3.1
Recommissioning after a short decommissioning period
Check that the softening system and all hydraulic connections are in proper working order,
and that the salt dissolving tank is completely filled with regenerating salt
Plug in the mains plug
Slowly open shut-off valves in raw and soft water lines
