9.1 Procuring spare parts

The original components of the product
were also certified by the manufacturer as
part of the declaration of conformity. If you
use other, non-certified or unauthorised
parts during maintenance or repair work,
this may void the conformity of the product
and it will therefore no longer comply with
the applicable standards.
We strongly recommend that you use ori-
ginal spare parts from the manufacturer as
this guarantees fault-free and safe opera-
tion of the product. To receive information
about the available original spare parts,
contact the contact address provided on
the back page of these instructions.
▶
If you require spare parts for mainten-
ance or repair work, use only the spare
parts that are permitted for the product.
10 Inspection and
maintenance

Carry out a function check and visual
inspection of the product every three
years.
▶
If the water is extremely calciferous,
you must de-scale the product more
frequently.
If the water has a large volume of suspen-
ded matter, the water filter in the cold wa-
ter flow must be replaced more frequently.
