Before disposing of an old machine, first
make the door lock unusable. This way you
will prevent children from accidentally
locking themselves in and endangering their
lives.
Keep these instructions in a safe and
accessible place.
Warning and Safety instructions
risk
of component damage.
The use
of agents containing chlorine, such
as sodium hypochlorite and chlorine bleach
in powder form, can damage the protective
upper
surface of stainless steel and cause
corrosion to components. Factors affecting
this are chlorine concentration levels,
contact time and temperature. It is therefore
advisable to avoid the use of such agents.
Oxygen
based bleaching agents should be
used instead.
If, however, chlorine based bleaching
agents have to be used for particular types
of soiling, then anti-chlorine measures must
also be carried out. If this is not done
irreparable damage can occur to
components in the machine and to laundry.
Anti-chlorine treatment
Anti-chlorine treatment has to be carried out
immediately after chlorine bleach has been
used. The use of hydrogen peroxide or an
oxygen based cleaning or bleaching agent
is recommended and the laundry should not
be drained in between.
With thiosulfate, especially when used with
hard water, gypsum can form, which can
lead to incrustations on laundry or deposits
in the machine. The use of hydrogen
peroxide is preferable as it aids the chorline
neutralising process.
The exact quantity of additives and the
treatment temperatures required must be set
and tested on site in accordance with the
dosage recommendations
of the detergent
and additive manufacturers. The laundry
must also be tested to check whether it
contains any active chlorine residues.
