Miele PG 8527 Operating Instructions Manual page 9

~
Pre-treating (e. g. with cleaning
agents or disinfectants), some types of
soiling and the interaction of certain
processing chemicals can cause
foaming. Suds can have an adverse
effect on the cleaning and disinfecting
results obtained. Pre-treatment agents
need to be completely removed before
placing the items in the
washer-disinfector.
~
The process must be adjusted so
that no foam escapes the wash
chamber. Escaping foam jeopardizes
the safe operation of the
washer-disinfector.
~
The processing must be checked
regularly by the operator in order to
detect any foaming.
~
To avoid damage to the
washer-disinfector and the associated
accessories by the effect of process
chemicals, introduced contamination or
their interaction, the instructions in the
chapter "Chemical Process
Technology" must be followed.
~
Even when a chemical additive (e.g.
a cleaning agent) is recommended, the
washer-disinfector manufacturer takes
no responsibility for the effect of such
chemicals on the labware/instruments
involved.
Note that formulation changes, storage
conditions, etc., that are not disclosed
by the manufacturer may adversely
affect the cleaning results obtained.
Safety Instructions and Warnings
~
When using process chemicals,
always follow the instructions opf the
chemicals manufacturer. To avoid
material damage and the possibility of
violent chemical reactions (e.g.
hydrogen gas reaction), always comply
with the manufacturer's intended
application(s) for a given cleaning
agent.
~
For critical applications, where very
high processing requirements have to
be met, it is strongly recommended that
all process-related factors (processing
chemicals, water quality, etc.) be
discussed in advance with Miele.
~
In addition, for applications that
demand especially stringent cleaning
and rinsing results, (e.g., chemical
analysis) the operator must ensure that
quality control occurs on a regular
basis, to meet the standards involved.
~
Only use mobile units, modular
baskets, and inserts as intended by the
manufacturer.
Hollow items must be positioned for full
exposure to rinse water.
~
Empty all liquids from containers
and hollow items before loading them
into the washer-disinfector.
~
Ensure that no acid or solvent
residues, especially hydrochloric acid
or chloride solutions, get inside the
wash chamber. Never place corroding
ferrous materials in the
washer-disinfector. Only trace amounts
of any organic solvents should be
present in any soiling.
