10.3 Refilling with rinse aid
External storage container
The container is located in the immediate vicinity of the machine.
Check the level and, if necessary, replace the container by a full one.
Only non-foaming acid rinse aid (pH < 7) suitable for commercial dishwashers may be
used.
If you suspect a malfunction, check the final rinse dosing unit. Visual inspection!
10.4 Cleaning
After emptying the tank, proceed as follows:
Do not use a foaming detergent for dish-washing by hand for pre-cleaning close to the
warewashing machine. Foam can cause malfunctions in the warewashing machine
and a poor wash.
Food residues sticking to the tank, tank heating element and sieves must be removed
with a brush.
Disassemble the wash arms and rinse them with flowing water.
Wash nozzles must be cleaned daily.
The cleanliness of final rinse nozzles must be checked weekly and if necessary clean
under running water.
The inserts for the final rinse nozzles must be inserted with the prongs facing the water
flow.
10.4.1 Safety instructions for cleaning
The tank heating element may still be hot after the tank has been emptied. As a result,
there is a risk of burns or scalding when cleaning the machine manually!
Machine, switch cabinet and other electrical components may not be sprayed with a
water hose or high-pressure cleaner.
10.5 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 discolora-
tion.
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).
