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
specifications. 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.
… only appropriately qualified an
d 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
maintenance and repair personnel.
... a
functional
test on all safety systems of the machine / installation is carried out during
every regular m
aintenance.
... 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.
... to work with rubber gloves during the cleaning and the main
tenance 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
legible.
... 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
maintenance 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
customer/operator, no modifications ma
y be made (e.g., electrical system or location).
Modifications to the washing machine, and in particular technical modifications carried out
without the manufacturer’s written authorization, or any modifications carried out by
unauthorized persons, will le
ad 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
operating temperatures, as set out in DIN 10510, 10511 and 10512. I
f you, the client,
install equipment for optimising energy consumption, any possible reduction in the quality
of the wash and hygiene is your responsibility.
5.2. Basic safety measures
Danger can arise from the improper use of the machine or if it is used
for purposes for
which it was not intended.
Parts carrying electric current as well as moving or rotating parts can cause
•
dangers to the user’s life and limb and
•
material damage
result.
The machine may only be operated by adequately qualified staff wh
o have been trained
by the operating company and who have been trained about the hazard and safety
instructions.
Qualified staff, as defined by the Operating Instructions, are persons:
•over 14 years of age
•who have read and who observe the safety instructions,
•who have read and who observe the operating instructions (or the part applicable to
the work to be carried out).

by specialists only. Observe accident prevention regulations.
The operator must not restart the washing machine until
all cover panels have been put
back in place.
The machine, switch cabinets and other electrical components must NOT be sprayed with
a hose or a high pressure cleaner.
The washing machine may only be operated under the supervision of trained personnel.
Do not use the
washing machine if you are unsure about system operation.
Always keep doors and hatches closed!
As there is a risk of becoming caught by the transport belt and/or items during transport,
operating personnel must wear close
-fitting clothes and avoid wearing rings, bracelets or
similar. We also recommend wearing safety shoes with steel toe caps!
The tank heating elements may still be hot after the tank has been emptied. As a result,
there is a risk of burns or scalding when cleaning the mach
ine manually!
All work and troubleshooting of the steam installation must be carried out qualified
professionals.

The corresponding electrical wiring diagram can be found in the switch cabinet. This
wiring diagram is a part of the machine and must therefore not be removed!
The type plate with the connected electrical loads is located inside the switch cabinet.
General Electrical Regulations must be observed when connecting the machine to the
power supply.
Caution:
The pre-fuse in the building must be chosen to meet local
requirements and match the nominal machine current in order to
provide back up- protection (VDE 0100 for Germany).
The mains supply cable must be provided with fuses in accordance
with regulations and must have a main switch (accessible on site or on
the appliance for operating personnel). If the neutral line (N) is not
earthed, you must use a 4-pin master switch. Mains connecting leads
must be oil-resistant, shielded cables no lighter than an H 07 RN-F
cable.
The potential equalisation connection must be carried out in
accordance with the requirements of the local electricity supply
company and all applicable local regulations (in Germany VDE 0100
Part 540 must be observed).
VDE 0160/EN 50178 specifies that within electrical equipment
featuring/planning residual current devices on the grid side to install
AC/DC sensitive type B FC frequency converters upstream of the
installed type A FC frequency converters- must be used.
A 5-pin terminal rail is provided for the mains connection (L1, L2, L3, N,
PE).
The electrical connection data, voltage, type of current, output can be seen on the type
plates on the machine.
Please check the voltage.
Route all electrical cable connections through the marked cable gland to the intended
terminals and contactors in the electrical cabinet and connect to the intended terminals
and contactors.

8 Adjustment of the machines effected by a service
technician during the first setting in operation
8.1 Commissioning
To avoid damages or dangerous injuries during the setting in operation of the washing
machine, please observe the following points:
Perform any required initial checks on supplied parts, such as heat pumps or other units.
More detailed information, if required, can be found in the relevant operating instructions.
•The setting in operation must be executed by qualified personnel under consideration
of the safety standards.
•Before the first start, check if all tools and foreign parts are removed out of the
installation.
•Check any escaped fluids have been removed.
•Activate all the safety systems and door switches before commissioning.
•Check that all screw connections are tight.
•Please also read the chapter “General safety instructions".
Commissioning and training will be handled and provided by MEIKO-trained service
engineers. The operator must not use the installation before completing training.
8.2 Chemical product settings
The correct settings for the quantity of detergent and rinse aid depend on the product
used. The relevant chemical product supplier can install the correct setting.
8.3 Work prior to initial commissioning
It is paramount to comply with the instructions in this section prior to initial commissioning.
−Water-carrying pipes
All pipes must be thoroughly flushed. The heating system must be switched off when
this is done (remove the fuses) in order to prevent the heating elements from
operating when the system is dry. Subsequently clean all dirt traps.
−Steam pipes
All pipes must be thoroughly flushed. In this process, all control valves must be open
and all condensation traps must have been removed. Subsequently clean all dirt traps.
−Electrical connection
•Retighten all electrical terminals in the switch cabinet; check that electrical plug-in
connections are firmly seated.
•Check all motors for correct sense of direction.
•Carry out a visual check on all electrical equipment (e.g. switches, cables,
housings, covers).
•Carry out functional tests on all electrical switches.
CAUTION!
