H Maintenance
1 | Basic information
In order to guarantee the reliable function of water softeners
over a long period of time, some maintenance work has to be
performed at regular intervals. This applies in particular to the
softening of drinking water where the required measures are
defined in the pertinent regulations and guidelines. All
regulations and guidelines which apply at the installation site
must be strictly adhered to.
DIN 1988 part 8 / A 12 stipulates:
an inspection must be performed at least every 2 months.
Maintenance must be carried out twice a year.
In case of water softeners that carry a DVGW certificate,
yearly maintenance is sufficient!
Maintenance must be performed by the Grünbeck’s technical
service/authorised service company or by an approved
company.
An operating log must be kept in order to document the
maintenance work performed.
Notes:
A maintenance contract ensures that any required
maintenance work is performed in due time.
The operating log is attached to this operation manual.
2 | Inspection (functional check)
You may perform the regular inspections yourself. We
recommend inspecting the water softener at shorter intervals
after installation, before switching over to the standard
inspection cycle. However, an inspection is compulsory at least
every 2 months.
Please refer to the following summary for the tasks to be
performed within the framework of an inspection.

Determine the soft water hardness (0°dH (°f, mmol/l)) or the
