Safety notes

2.3 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 very important that this basic safety requirement is tested and in case of doubt the house installation is checked by a qualified electrician.

Winterhalter cannot be held responsible for damage caused by a missing or broken earthing system (e.g. electrical shock).

2.4 Safety Instructions for Maintenance and Repairs

Maintenance work and repairs may only be performed by service technicians authorised by Winterhalter. Improper maintenance or repairs may cause significant danger for the user, for which Winterhalter is not liable.

When performing maintenance and repair work, unplug machine from the power network. Electricity consumers (heating element, frequency inverter, ...) are under voltage until the on-site mains disconnect switch has been operated.

Only original Winterhalter spare parts may be used for maintenance and repairs. If original spare parts are not used, the warranty is invalidated.

A damaged or leaking machine can endanger your safety. In case of defects, switch off the machine immediately. Switch off the on-site mains disconnector (main switch). Only then is the machine without power.

Do not operate a damaged machine. In case of defects resulting from an unknown cause, switch off the machine, and do not switch it on until the defect has been rectified.

Contact your installer or electrician if the on-site water or electricity supply is the cause of the malfunction.

Notify an authorised service technician or your retailer if another fault has occurred.

If the mains cable of this machine is damaged, it must be replaced by the Winterhalter or its Customer Service or another qualified person in order to prevent hazards. The mains cable must be H07 RN-F type or equivalent.

Rinse aid and detergent

5 Rinse aid and detergent

When handling chemicals, observe the safety precautions and the dosage recommendations on the packaging.

Danger Wear protective clothing, protective gloves and protective goggles when handling chemicals.

Use only products that are suitable for commercial dishwashers. Such products are appropriately marked. We recommend Winterhalter products. These are especially adapted to

Caution	Winterhalter dishwashers.
	Do not put rinse aids in the storage container for detergents and vice versa.

5.1 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. Rinse aid is automatically dosed from an external container. The rinse aid dosing device is an integral component of the machine. The dosing amount is set by the authorised service technician when commissioning the machine ( 12.6).

5.2Detergent

Do not use acidic detergents.

Do not mix different detergent products in order to prevent crystallisation that could destroy

		the detergent dosing device ( 5.4)
	Caution
		Do not use products that can create foam, e.g. hand soap, soft soap, hand wash liquid. En-
		sure that these do not enter the machine even during the pre-treatment of the dishes.

A detergent is necessary to ensure that the leftovers and dirt on the dishes is cleaned. Detergents can be dosed as follows:

Manually as detergent powder.

Automatically from an external container using a detergent dosing device.

INFO The detergent dosing device is not included in the scope of delivery of all machines. When using an external dosing device, a transfer strip is available for connecting the dosing device ( 18).

5.2.1 Manual dosing of detergent powder Pre-dosing

Switch on the machine and wait until the start button is lit green.

Adhere to the dosing instructions on the packaging of the detergent. The machine's tank capacity is approx. 35 litres.

Place approx. 100 g of detergent powder in the machine. This corresponds to a dosing of approx. 3 g/l.

Then start the wash cycle immediately to mix the detergent powder with the water.

Post-dosing

At each wash cycle approx. 2.0-2.5 litres of fresh water enter the dishwasher, which must be mixed with detergent powder.

 Fill approx. 30 - 40 g detergent powder into the machine after 5 wash cycles.

5.2.2Automatic dosing of liquid detergent

The dosing amount is set by the authorised service technician when commissioning the machine ( 12.6).

5.3Suction tube with level control

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 detergent container or vice versa.
Caution
		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. The suction tube is already connected to the machine.

Servicing and maintenance

Rinse the suction tube at every container change under running water. Remove crystallised detergent residue.

Ensure that both vent holes (a) in the caps are open.

Put the suction tube back into the container. Slide the cap downwards until the container opening is closed.

5.4Changing the detergent product

Mixing different detergents can lead to efflorescence that can lead to a failure of the detergent dosing device. This is applicable even if the new detergent is from the same manufac-

		turer.
	Caution
		The dosing tubes and the detergent dosing device must be thoroughly rinsed with water
		before the new detergent is used.

 A new detergent product usually requires a new setting of the detergent dosing device. Assign the required work to an authorised service technician to attain good cleaning results.

If this is not done, the warranty and product liability of Winterhalter Gastronom GmbH expires.

Integral water softener (special equipment)

Procedure:

Observe the safety precautions when handling chemicals and the dosage recommendations on the packaging.

Danger		Wear protective clothing, protective gloves and protective goggles when handling chemicals.
		Do not mix different detergents.

 Remove the suction tube from the container and place it in a water-filled container.

 Rinse the dosing tube and the detergent dosing device with water. To do this, use the "prime dosing device" function several times ( 10). The frequency depends on the length of the dosing tubes.

 Place the suction tube in the new detergent container.

 Use the "prime dosing device" function several times ( 10), to replace the water in the dosing tubes with detergent.

5.5 Priming the dosing devices

Dosing devices must be primed when air is reached in the dosing tubes because the containers were not exchanged or refilled in time ( 10).

6 Integral water softener (special equipment)

By softening the inlet water, limescale build-up in the machine and on the dishes is avoided. For the integral water softener to work correctly, the salt container must be filled with regeneration salt.

INFO At the commissioning of the machine the authorised service technician measures the water hardness and saves it in the machine's electronic control unit.

6.1 Lack of salt display

A pictogram appears on the screen when an empty salt container requires refilling. The display disappears after filling the salt container, as soon as approx. 3 wash cycles have been completed and part of the salt has been dissolved.

6.2 Filling regeneration salt

	Possible risk of damage to the water softener
	Chemicals such as detergent and rinse aid inevitably lead to damage to the water softener. Fill
Caution	only with regeneration salt or pure evaporated salt.

Possible malfunction of the water softener

Do not fill with other salts (e.g table salt cleaning or de-icing salt). These can contain waterinsoluble components. Fill only with fine-grained salt (max. 0.4 - 7 mm grain size).

INFO Because of their size, salt tablets are not suitable.

 Proceed in accordance with Figures A1 to A5. IMPORTANT Figure A2 is only relevant for the first filling.

Risk of rust formation in the filling area

Immediately after filling, start a wash cycle to rinse off any salt residue.

Caution
