Safety notes

3.2 Electrical safety

The electrical safety of this machine is guaranteed only if it is connected to a correctly
installed protective circuit and a residual current circuit breaker. It is crucial that this
basic safety requirement is tested and, in case of doubt, that the house installation is
checked by a qualified electrician.
Winterhalter cannot be held responsible for damage caused by a missing or broken
protective conductor (e.g. electrical shock).
3.3 Maintenance and repair work

When performing installation, maintenance and repair work, unplug the machine from
the mains supply.

Maintenance work and repairs may only be performed by authorised Winterhalter
service technicians. Improper maintenance or repairs may cause significant danger for
the user, for which Winterhalter is not liable.

Original spare parts must be used for repairs or to replace consumable parts. If original
spare parts are not used, the warranty is invalidated.

Operate this machine only when it is in perfect condition.

A damaged or leaking machine may endanger your safety. In case of danger and/or
defects, switch off the machine immediately. Switch off the on-site mains disconnector
(main switch). Only then is the machine without power.

Contact your installer or electrician if the on-site water or electricity supply is the cause
of the malfunction.

Contact an authorised service technician or your dealer if any other fault occurs.

If the mains cable is damaged, to prevent hazards it must be replaced by Winterhalter
or its Customer Service or another qualified person. The mains cable must be an oil-
resistant, encased and flexible wire. The wire type H07RN-F is recommended.
3.4 Handling chemicals (detergent, rinse aid, descaler, etc.)

When using chemicals, comply with the safety notes and recommended dosages
printed on the packaging.

Wear protective clothing, protective gloves and protective goggles when handling
chemicals.

Only use products that are suitable for commercial dishwashing machines. Such
products are marked accordingly. We recommend using products developed by
Winterhalter. These products are specially adapted for Winterhalter dishwashing
machines.

Do not mix different detergent products together as this could result in crystallisation
and consequently cause irreparable damage to the detergent dosing device.

Do not use any foaming products, e.g. hand soap, soft soap, manual wash-up cleaner.
These products may not enter the machine, even through pre-washing of the dishes.
