5 Repairs and maintenance

5.1 Maintenance and wearing parts

You have purchased a product that is durable
and easy to service. However, all technical
equipment requires regular servicing so that it
continues to function properly.
If the product malfunctions during the warranty
period, contact your contract partner or the
installation company, and quote the unit type
and serial number.
Observe: Please also observe the pro-
visions in the operating manual of the
installed external pre-filter.
Before performing work on electrical
components or opening the housing,
it is mandatory that the mains plug
be pulled and both the water infeed
and the permeate line be closed off in
order to guarantee that the unit is volt-
age-free.
Whenever maintenance is performed,
the connection lines and the device
must be checked for damage.
Note: Only customer service may
replace the wearing parts (e.g. after a
faulty pump).
