If there is an extended power failure (8 hours), the unit starts operation with
a regeneration when the power returns.
If the power failure occurred during a regeneration, the controller regener-
ates the column in which the regeneration process was interrupted when
power returns.

BWT drinking water softening units are produced and supplied hygienically.
After start-up the ion exchanger resin tends to become infected if shut down
incorrectly and therefore to release organic substances.
Therefore, the procedure described below is required under the following
conditions:
If no water is available for more than 48 h (e.g. for modifications, the softe-
ning unit is disconnected from the drinking water network).
If the softening unit is not required for an extended period (more than
4 weeks, e.g. seasonal operation in a hotel).
Ideally, the softened water supply should be almost completely used up
before shutting the unit down.
The columns should only being flushed and not regenerated.
If this is not possible, the unit should be regenerated completely.
The water supply to the unit can now be shut off and the unit can be
disconnected from the power supply.

The unit must be completely regenerated anyway (both columns for
2 column units).
We recommend hygienic maintenance by our after-sales service team after
the unit is shut down.
