Miele G 7883 Operating Instructions Manual page 7

~
The machine must be disconnected
from the mains electricity supply before
any maintenance or repair work is
carried out. Do not reconnect it until the
maintenance or repair work has been
successfully completed.
The following points should be
observed to assist in maintaining
quality standards when processing
laboratory glassware and utensils, in
order to avoid damage to the loads
being cleaned.
~
If the machine is being used for
disinfection, the steam condenser and
its connections to and from the wash
cabinet must be cleaned and
disinfected whenever any repairs are
carried out or parts replaced.
~
If it is necessary to interrupt a
programme in exceptional
circumstances, this may only be done
by authorised personnel.
~
The standard of cleaning and
disinfection in the disinfection
programmes must be routinely
confirmed by the user. The process
should be validated on a regular basis,
and checked against documented
control results.
~
For thermal disinfection, use
temperatures and temperature holding
times to achieve the required infection
prophylaxis in accordance with current
health and safety regulations.
Warning and safety instructions
~
Chemical disinfection agents should
only be used for items which cannot
withstand the higher temperatures used
by thermal disinfection. The range of
effective disinfection is based on claims
made by the producer of the
disinfecting agent. Their instructions on
handling, use and effectiveness must
be observed. The use of chemical
disinfection procedures is the
responsibility of the operator.
~
Only use chemical agents
formulated for special processes and
approved by Miele for use with this
machine. Use of unsuitable agents
could adversely affect the components
of the machine. In the event of any
damage or material deterioration
please contact Miele Service.
~
Pre-treatments with cleaning or
disinfecting agents can create foam, as
can certain types of soiling and
chemical agents. Foam can have an
adverse effect on the disinfection and
cleaning result.
~
Foam must not be able to escape
from the wash cabinet. It would hinder
the correct functioning of the machine.
~
Check the process used regularly to
monitor foaming levels.
~
To avoid the risk of damage to the
lab washer and any accessories used
with it caused by chemical agents,
soiling and any reaction between the
two please read the notes in "Chemical
Processes and Technology".
