3 | Maintenance

According to DIN 1988 part 8 / A 12, maintenance work at water
softeners may only be performed by Grünbeck’s technical
service/authorised service company or an approved company.
An operating log must be kept for water softeners. In this
operating log, the customer service technician records all
maintenance and repair work performed. In case of mal-
functions, this log helps to identify possible sources of error. In
addition the log documents the proper system maintenance.


Note: Make sure that all maintenance work is recorded in the
operating log.
