5 Rinse aid and detergent
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.
Caution
Use only products that are suitable for commercial dishwashers. Such products are appro-
priately marked. We recommend Winterhalter products. These are especially adapted to
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 service engineer authorised by Winterhalter sets the dosing level when
commissioning the machine (12).

Rinse aid and detergent
6
5.2 Detergent
Caution
Do not use acidic detergents.
Do not mix different detergent products in order to prevent crystallisation which could de-
stroy the detergent dosing device (5.4).
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
supplied 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 (16).
5.2.1 Manual dosing of detergent powder
Pre-dosing
Switch on the machine and wait until the display is lit green.
Adhere to the dosing instructions on the packaging of the detergent. The machine's tank capacity is ap-
prox. 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. 2.5 litres of fresh water enter the dishwasher, which must be mixed with deter-
gent powder.
Fill approx. 40 g of detergent powder in the machine after 5 wash cycles.
5.2.2 Automatic dosing of liquid detergent
The authorised service technician sets the dosing amount when commissioning the machine (12).
5.3 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 detergent container 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. The suction tube is already con-
nected to the machine.

Servicing and maintenance
Rinse the suction tube at every container change under running water. Re-
move 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.
5.4 Changing the detergent product
Danger
Mixing different detergents can lead to efflorescence that can lead to a failure of the deter-
gent dosing device. This is applicable even if the new detergent is from the same manufac-
turer.
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 re-
quired work to a service engineer authorised by Winterhalter to attain good results.
If this is not done, the warranty and product liability of Winterhalter Gastronom GmbH expires.
Procedure:
Danger
Observe the safety precautions when handling chemicals and the dosage recommendations
on the packaging.
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 de-
vice" function several times (12). 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 (12), 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 (12).
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 authorized service technician measures the water hard-
ness and saves it in the machine's electronic control unit.
6.1 Lack of salt display
A pictogram appears in the display 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.

Operation

6.2 Filling regeneration salt
Caution
Possible risk of damage to the water softener
Chemicals such as detergent and rinse aid inevitably lead to damage to the water softener.
Fill 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 water-
insoluble components. Fill only with fine-grained salt (max. 0.4 - 7 mm grain size).
INFO Salt tablets are not suitable.
Proceed in accordance with Figures B1 to B5.
IMPORTANT Figure B2 is only relevant for the first filling.
Caution
Risk of rust formation in the filling area
Immediately after filling, start a wash cycle to rinse off any salt residue.
