3 Safety notes
3.1 General safety notes
Read through the safety notes and operating instructions in this manual carefully.
Winterhalter Gastronom GmbH does not assume liability or warranty in case of non-
compliance with these safety and operating instructions.
Use the warewasher only 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.
Do not climb or sit on the opened hinged door.
Train the operating personnel as regards handling the machine and inform them about
the safety notes. Repeat the training sessions at regular intervals to prevent accidents.
For your safety, test the on-site residual current circuit breaker (FI) regularly by pressing
the test button.
Close the on-site water stop cock after the work is complete.
Switch off the on-site mains disconnector after the work is complete.
Warning
Risk of crushing when closing the door
Do not place hands or objects beside or behind the
upper part of the door.
When closing the door, there is a risk that fingers or
objects may become trapped in the gap and be crushed.
The hazardous area is normally out of the reach of the person who
closes the door. The risk is only posed to persons who are also on or
in the vicinity of the machine.
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.

Before working with the machine
4
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
H07 RN-F type or equivalent.
4 Before working with the machine
Have the machine set up by an authorised service technician or your dealer (14).
Have the machine connected as per the locally applicable standards and the regulations of the authorised
mechanics (water, waste water, electrical system) (15).
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.

5.2 Mode of operation
The boiler and the tank fill are warmed up to the operating temperature after the machine is switched on.
During the heating-up phase, the lighting of the start button changes gradually from red to green. When the
rated temperatures are reached, the machine is ready for use. The start button lights up green.
The machine is fully automatic with programmes consisting of three steps: Wash, Drain and Rinse. While a
washing programme is running, the start button gradually changes from blue to green.

5.3 Options
The following options are available by default:
Energy
Requirement: Connect the machine to the cold water.
The structure above the machine includes a fan motor and a heat exchanger. The fan motor extracts the
moist, warm air (= vapours) out of the washing compartment and transfers the generated energy to the
cold inlet water via a heat exchanger.
Long-term improvement in the kitchen climate and reduced operating costs.
Hinged door (10.1.2)
The following options can be fitted on request:
Cold water pre-wash (6.3.2.2)
Requirement: Second water connection (max. 20 °C) required.
At the beginning of the washing programme, starch and protein deposits are rinsed away with cold water.
This prevents caking of starch and protein deposits.
Defoamer dosing device
Increased protein in the warewasher causes significant foam build-up. Adding a defoamer helps prevent
foam forming.
Improvement of wash result.
Dosing device for crust cracker (TurboZyme process)
Before the actual wash cycle, the wash items are moistened with the crust cracker (special cleaning
agent) (6.3.2.1). Next is a soaking phase.
Dried-on residues can be removed effortlessly, even without manual pre-rinsing.
Screen protector
5.4 Customer-specific modifications
The controls of the machine can be adapted to individual needs within certain limits.
Examples
The rinsing pressure can be adapted to the wash items.
The cold water pre-wash can be activated for individual programmes.
The beep which occurs when a button is pressed can be disabled.
Contact an authorised service technician for any changes.

Because the hygiene logbook stores only a limited number of entries, there is also the possibility to transfer
the records to a PC and archive them there.
For more information, see the related documents.
7.5 Descaling / basic cleaning
7.5.1 Descaling programme
If the machine is operated with hard water without water treatment, the boiler, the machine interior, all water
lines and other components may scale.
Grease residues and dirt that remain in the machine can contribute towards an unhygienic interior and can
lead to failure of heating elements. Regular removal of these layers is absolutely essential.
Using the descaling programme you can descale the interior of the dishwasher. The water lines and the
boiler can only be descaled by an authorised service technician.
For descaling, you need an acid-based descaler suitable for commercial dishwashers. We recommend the
Winterhalter Descaler A 70 LS.
Danger
When handling chemicals, observe the safety precautions and the dosage recommendations
on the packaging.
Wear protective clothing, protective gloves and protective goggles when handling chemicals.
Ideally, start the descaling programme when the machine is empty and switched off. If the machine is
already prepared for use, it will automatically empty first.
Only with an external detergent dosing device:
Warning
Development of chlorine gas
If you mix active chlorinated detergent and descaler, chlorine gas is produced. Stop the
detergent dosing (e.g. remove the suction tube or switch off the dosing device).
INFO A detergent dosing device built into the machine will be disabled automatically in the descaling
programme.

PIN menu
18
Starting the descaling programme
Tap the following buttons in turn:
The button flashes while the
programme is running.
Warning
Descaler causes corrosion
The descaling solution must not remain in the machine. If you switch off the machine when the
descaling programme is in progress or if you terminate the programme, the machine must be
emptied, refilled and again emptied. Use the self-cleaning programme for this.
Sequence of the descaling programme
Open door.
Close door.
Open the door and check the result:
Continue with step 8.
Close the door and repeat steps 5 + 6.
Close door.
Put descaler
(A 70 LS) into the
tank:
UF-M/UF-L: 690 ml
UF-XL: 1380 ml
Add descaler.
Press start button.
Test descaling.
Good: Press button 28.
Bad: Press start button.
