5 General safety instructions
5.1 Operator’s duty of care
The washing machine has been constructed based on a risk analysis and after careful
selection of the applicable harmonized standards, as well as additional technical specifica-
tions. It is therefore state of the art and guaranteed to provide maximum safety.
Safety can only be guaranteed during operation if all necessary measures are taken. The
operator of the machine has an obligation of care to ensure that these measures are
planned for, and also to check that they are correctly implemented.
Measures to ensure the safe machine operation
The operator must ensure in particular that ...
... the washing machine is only used in accordance with the regulations
in case of other use or operation, damage or risks may arise for which we accept no liability
(cf. chapter "Intended use").
… in order to guarantee functionality and safety, use only original parts supplied by the
manufacturer when needed.
Any potential claims by the user shall be rendered void if the system was altered using
parts other than original spare parts.
CAUTION!
… only appropriately qualified and authorized personnel operate, maintain, and repair the
installation.
… staff is regularly trained in all questions relating to occupational safety and environmental
protection and, in particular, that staff is familiar with the Operating Instructions as well as
with the safety instructions they provide.
… the washing machine is only operated in a perfect, operationally efficient condition and,
in particular, that the safety systems and switch elements are checked on a regular basis
for their operational efficiency.
... the required personal protective equipment is made available to and used by mainte-
nance and repair personnel.
... a functional test on all safety systems of the machine / installation is carried out during
every regular maintenance.
... all doors and flaps must be closed!
... no one must remain inside the machine when the door is closed!
... the wash tank in the washing zone must remain closed while the machine is in operation.

... when the machine is in operation:
the doors of tray-carrying trolleys must be open in the washing position and
properly secured,
there must be no trays, dishware or menu-card holders in or on the trolley.
loose, inorganic soiling (e.g. rubber gloves, plastic cups, aprons, aluminium lids
etc.) has been removed.
... to work with rubber gloves during the cleaning and the maintenance works.
... the operating instructions are always in a legible state, complete, and available at the
machine's location of use.
... all the safety, warning and operating instructions provided are not removed and are leg-
ible.
... any necessary initial tests to parts supplied by sub-suppliers, such as heat pumps or
other equipment, must be carried out. More detailed information, if required, can be found
in the relevant operating instructions.
…with the use of demineralised, osmosis and desalinated water as preventative mainte-
nance measures, the return spring in the final rinse must be replaced every 4-6 months.
After installation, commissioning and handing over of the washing machine to the cus-
tomer/operator, no modifications may be made (e.g., electrical system or location). Modifi-
cations to the washing machine, and in particular technical modifications carried out with-
out the manufacturer’s written authorization, or any modifications carried out by unauthor-
ized persons, will lead to the complete loss of any guarantee claims and will invalidate
any liability for the product.
... equipment for optimising energy consumption must not be used to reduce essential op-
erating temperatures, as set out in DIN 10510, 10511 and 10512. If you, the client, install
equipment for optimising energy consumption, any possible reduction in the quality of the
wash and hygiene is your responsibility.

13.4 Care of stainless steel surfaces
We recommend cleaning the stainless steel surfaces only when needed with cleaner and
care products suitable for stainless steel.
Lightly soiled parts can be wiped with a (possibly damp) cloth or sponge.
Be sure to wipe dry after cleaning to avoid traces of scale. Use demineralised water if
possible.
Do not use aggressive cleaning or scouring agents.
The care products must not attack the stainless steel, form deposits, or cause discoloration.
Never use cleaning agents that contain hydrochloric acid or bleaches based on chlorine.
Never use cleaning equipment that you have used previously by non-stainless steel to
avoid external corrosion.
Aggressive external influences due to cleaning and care products that evaporate in the
vicinity of the dishwashing machine, or caused by direct application, can lead to machine
damage and put the material at risk (e.g., aggressive tile cleaners).
Caution!
Observe the manufacturers' hazard warnings on the original containers and safety data
sheets.
