IMPORTANT SAFETY INSTRUCTIONS

Chlorine and component damage


Frequent use of chlorine products increases the risk of damage to
components.

The use of substances containing chlorine, such as sodium
hypochlorite and chlorine bleach in powder form, can however result
in damage of the protective layer of stainless steel and corrosion on
components. Therefore, refrain from using substances containing
chlorine. Use oxygen-based bleaching agents instead.
If, however, chlorine bleaching agents are used, an anti-chlorine treat-
ment must always be carried out. Otherwise, both the washing-ma-
chine components and the load may suffer persistent and irreparable
damage.

Anti-chlorine treatment must be carried out immediately after chlo-
rine bleaching agents have been used. Hydrogen peroxide as well as
oxygen-based detergents and bleaching agents are suitable for anti-
chlorine treatment. The suds must not be drained in between.
Treatments with thiosulphates can result in gypsum-like deposits par-
ticularly when used in combination with hard water. This gypsum can
build up in the washing machine or cause incrustations on the laun-
dry. Treatment with hydrogen peroxide is recommended over treat-
ment with thiosulphates because hydrogen peroxide neutralizes chlo-
rine.
The exact dispensing quantities and the treatment temperatures re-
quired must be set and tested on site in accordance with the dis-
pensing recommendations of the detergent and cleaning agent man-
ufacturers. The laundry must also be tested to check whether it con-
tains any active chlorine residues.
