4. Operating instructions

Once the dishwasher has been correctly installed, prepare for use as follows:

• Adjust the water softening system;

• Add the regenerating salt;

• Add the rinse aid and detergent.

4.1 Using the water softening system

	The amount of scale contained in the water (water hardness
	index) can cause whitish staining on the dry dishes, which tend
	to become dull over time. The dishwasher is equipped with an
	automatic softening system which uses a special regenerating
	salt to reduce the hardness of the water.
	The dishwasher is factory set for water hardness level 3	SALT
	(average hardness 41-60°dF– 24-31°dH).	SALT
	(average hardness 41-60°dF– 24-31°dH).

When using water of medium hardness, the regenerating salt container should be refilled after approximately 20 washing cycles. The salt container can hold approximately 1.7 Kg of salt in grains. Some models are equipped with an optical no-salt indicator. In these models, the cap of the salt container contains a green float which descends as the salt concentration in the water drops. When the green float can no longer be seen through the transparent cap, the container must be topped up with regenerating salt. The container is situated at the bottom of the dishwasher. After removing the lower basket, unscrew the salt container cap by turning it anticlockwise and pour in the salt using the funnel supplied with the dishwasher. Before replacing the cap, remove any salt residues from around the opening.

•When using the dishwasher for the first time, in addition to the salt it is also necessary to add one litre of water to the container.

•Each time the salt container is refilled, make sure that the cap is securely closed. The mixture of water and detergent must never penetrate the salt container, as this would compromise the operation of the regeneration system. In the event of this occurring, the warranty will be invalidated.

•Only use regenerating salt specially formulated for domestic dishwashers. If using salt tablets, do not fill the container completely.

•Do not use table salt as it contains insoluble substances which, over time, may damage the water softening system.

•When necessary, refill the regenerating salt container before starting the washing program. In this way, the excess saline solution will be immediately removed by the water; the prolonged presence of salt water inside the tank may lead to corrosion.

Be careful not to confuse the salt and detergent packages; adding detergent to the salt container will damage the water softening system.
