3Safety notes
General safety notes
Read through the safety notes and operating instructions in this
manual carefully.
Retain the operating instructions for future reference.
Only use the warewasher after you have read and understood
the operating instructions.
Allow the Winterhalter Customer Service Department to provide
information about the operation and functioning of the warewasher.
Train the operating personnel as regards handling the machine
and inform them about the safety notes. Repeat the training ses-
sions at regular intervals to prevent accidents.
Operate this machine only when it is in perfect condition.
A damaged or leaking machine may endanger your safety. In
case of defects, switch off the machine immediately. Do not
switch the machine on until the defect has been rectified. Switch
off the local mains disconnector (main switch). Only then is the
machine without power.
Contact your installer or electrician if the on-site water or electrici-
ty supply is the cause of the malfunction.
Contact an authorised service technician or your retailer if any
other fault has occurred.
Close the on-site water supply after the work is complete.
Switch off the on-site mains disconnector after the work is com-
plete.

4
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 require-
ment 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).
Do not open any machine covers or machine parts if it requires
tools. There is danger of shock.
For your safety, test the on-site residual current circuit breaker
(FI) regularly by pressing the test button.
Maintenance and repair work
Maintenance work and repairs may only be performed by author-
ised Winterhalter service technicians. Improper maintenance or
repairs may cause significant danger for the user, for which Win-
terhalter is not liable.
When performing maintenance and repair work, unplug the ma-
chine from the power network. Electricity consumers (heating el-
ement) are under voltage until the local mains disconnector has
been operated.
Only original Winterhalter spare parts may be used for mainte-
nance and repairs. If original spare parts are not used, the war-
ranty is invalidated.
If the mains cable of this machine is damaged, it must be re-
placed by the Winterhalter or its Customer Service or another
qualified person in order to prevent hazards. The mains cable
must be an oil-resistant, encased and flexible wire. The wire type
H07RN-F is recommended.
4Before working with the machine
Have the machine set up by an authorised service technician or your dealer.
Have the machine connected as per the locally applicable standards and the regulations
of the authorised mechanics (water, waste water, electrical system).
After connecting the water and the power properly, contact the relevant Winterhalter
dealer or your dealer for the commissioning of the machine and for providing training in
its operation. Have yourself and your operating personnel trained in the operation of the
machine.

12 Rinse aid and detergent
Danger
Possible risk of chemical burn
Wear protective clothing, protective gloves and protective goggles when
handling chemicals.
When handling chemicals, observe the safety notes and the recom-
mended dosage on the packaging.
Caution
Use only products that are suitable for commercial warewashers.
Do not use products that can create foam.
Do not fill rinse aid in the container for detergent and vice versa.
Changing the chemical product
Caution
Possible risk of damage to the dosing device
Do not mix different products.
Crystallisation can destroy the dosing device and clog the hoses.
As a rule, a new product requires that the dosing device be rinsed with water and re-
configured.
To attain good wash results, assign the required work to an authorised service techni-
cian.
If this is not done, the Winterhalter Gastronom GmbH warranty and product liability will be
void.
Rinse aid
A rinse aid is necessary to ensure that water on the dishes drains off after washing and
dries off after a short while.
Detergent
Caution
Do not use acidic detergents.
Do not use any foaming products (e.g. hand wash) for treating the items
to be washed as these will build up in the machine.
A detergent is necessary to ensure that the leftovers and dirt on the wash items are
cleaned.
Dosing devices
Rinse aids and detergents must be dosed using external dosing devices. Dosing devices
are not included in the scope of delivery of the machine.
Connection of external dosing devices:  22.

13
Suction tube with level control
Caution
Only use the suction tube with sufficiently stable containers. Narrow and
tall containers can tip if the suction tube is pulled.
Do not place the suction tube for the rinse aid in the container with de-
tergent or vice versa.
Do not pull unnecessarily on the suction hose or main power cable, as
this may lead to a defect.
As an option with your machine you may have one or more suction tubes with level control:
