17 Maintenance, servicing
Regular maintenance is a prerequisite for the long-term reliable and safe operation of a
warewashing machine. Maintenance which is neglected or improperly carried out increases
the residual risk of unforeseen damage to property and persons, for which no liability will
then be assumed.
Maintenance work should only be performed when the washing machine has been
completely disconnected from the power supply via the locally available main switch.
Existing safety systems must not be removed!
CAUTION!
A functional test of all safety systems of the device/installation is carried out during every
regular maintenance.
We recommend concluding a maintenance contract with our authorised agency in order
to ensure safe functioning and a long service life of the appliance.
17.1 Basic safety measures during maintenance
Observe the maintenance intervals prescribed in the operating instructions!
Observe the maintenance instructions for the individual components in these operating
instructions!
Block access for unauthorised persons to the operating area of the installation before
starting maintenance or repair work! Display a sign drawing attention to the maintenance
or repair work!
Before performing any maintenance or repair work, the washing machine must be
switched off completely via the locally available main switch and secured against re-start
by using appropriate measures (e.g. via a padlock, the key for which is in the possession
of the person performing the maintenance or repair work)!
Failure to observe these precautions can result in serious bodily injury or damage to
property.
CAUTION!
Before carrying out any maintenance and repair work, ensure that all the parts of the
machine that may be touched have cooled down to room temperature!
Carefully dispose of any cleaning products that could harm the environment!
17.1.1 Before commissioning after maintenance or repair work
Before starting operations following maintenance or repair work, all initial tests must be
carried out as described in “Machine Settings for Initial Commissioning by the Service
Engineer”.
17.1.2 Observe environmental protection regulations
CAUTION!
For all work on or with the appliance, observe legal requirements relating to the avoidance
of waste materials and to their recycling/removal!
In particular, during installation, repair and maintenance work, materials that could pollute
water such as grease and oils or cleaning fluids containing solvents, must not pollute the
ground or run into the sewerage system! These materials must be stored, shipped,
collected and disposed of in suitable containers!
17.2 Dosing equipment
The dosing equipment itself is principally maintenance-free; however, the peristaltic tubes
built into the dosing equipment are not. The lifetime of dosing equipment depends on the
chemicals used. We recommend regularly replacing it during maintenance work.
