Cleaning

Clean the regenerative container with drinking water if it is dirty.
For hygienically demanding applications
For standard applications
8.4

Disinfection

For Rondomat DVGW only:
Disinfection is required if the unit was not used for more than 4 days
8.5

Power failure

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 rege-
nerates the column in which the regeneration process was interrupted
when power returns.
8.6

Shutting down

BWT drinking water softening units are produced and supplied hygie-
nically. 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
softening unit is disconnected from the drinking water network).
If the softening unit is not required for an extended period of time (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.
8.7

Reactivating the unit

To reactivate the unit after periods of decommissioning repeat the
Start-up procedure.
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.
