Cleaning
CAUTION
Do not use household cleaning
agents to clean the outside of the
device, but only use clear water to
avoid embrittlement of the plastic.
6.2
Warranty and maintenance
Prerequisite for obtaining the statutory war-
ranty claim is regular backwashing (see
chapter 4.1). The DIN EN 13443-1 pre-
scribes that the backwashing must take
place every six months. JUDO however rec-
ommends to comply with the information in
chapter 4.1.1 Backwashing interval.
To ensure the process operates success-
fully as long as possible, regular inspec-
tion and routine servicing of the device are
essential. Where home automation is con-
cerned, this is governed by DIN EN 806-5.
We recommend the conclusion of a main-
tenance contract, which is the best way
to ensure a good operating function, even
beyond the warranty period. The skilled
tradesmen or the factory customer service
are suitable partners for regular mainte-
nance work and the supply of consumables
and wear materials as well as for possible
repairs.
