Because of the risk of chemical burns, the prescribed protective clothing
(safety goggles, safety gloves, apron) must be worn during all service and
repair work on parts that come into contact with dangerous products and
supply containers.
Safety regulations on the handling of chemicals must always be observed.
Maintenance and repair may only be carried out by authorized personnel
with reference to these Operating Instructions.
Before repair work on product and water-bearing components

in the unit reduced. For this purpose, first press the start button and then
the (stop) pause button.
CAUTION!
Electrical repairs may only be carried out by a qualified electrician.
Prior to any repair work, the device is to be de-energized by isolating it from

Live parts may be exposed when opening covers or removing parts (apart
from covers that can be opened or parts that can be removed without using
tools). Connecting parts can also be live.
