Cleaning
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
Only use clear, clean drinking water to
clean the housing.
Domestic all-purpose cleaners and glass
cleaners can contain up to 25% solvents or
alcohol (spirits).
Such cleaners must therefore not be
used.

Warranty and Services
In order to comply with the legal warranty
claim, according to DIN 1988, Part 8, it is
necessary that the "… backwashing takes
place at least every 2 months, after operat-
ing conditions exist … ".
Regular servicing is indispensable in order
to continue to achieve a successful process
for many years after the unit is put into serv-
ice. In the building services sector this is
covered by DIN 1988, Part 8.
A servicing agreement is the best way to en-
sure a good operating function beyond the
warranty period.
Wherever possible, the regular servicing
work and supply with consumables and
wearing materials, etc. should be carried out
by the specialist trade or the factory’s cus-
tomer service department.
