Scale Scale is mainly calcium carbonate (chalk), a harmless, naturally occurring mineral found in most water supplies. "Hard" water contains more of this mineral than "soft" water. When the water is heated, the minerals in the water solidify, making the water appear cloudy. These minerals form a thin film on the walls, element and on the surface of the water. The water may look like it has white colored pieces of plastic floating on the surface. On traditional kettle elements, scale forms a hard white "crust" which adversely affects performance and reduces the life of the element. As soon as you notice a film forming on the water, or, when cleaning the filter, if you notice a film on the walls or the element, simply rinse the kettle and wipe it out. Water filter Your kettle is fitted with a water filter to prevent loose particles of scale being poured into your beverage. This filter is both removable and washable. The frequency with which you will need to clean any scale deposits from your filter will depend on the hardness of water in your area and how often you use the kettle. You should remove and clean the water filter when you notice any deposits being left on the filter or if the pouring efficiency is impaired. Removing the water filter • Allow the kettle to cool down completely. • Disconnect the appliance from the outlet. • Make sure that your hands are clean and free from soap, cream or anything which might taint the water. • Empty the kettle and remove the water filter as shown in fig. 1. • Rinse under a tap while cleaning with a soft brush (fig. 2). • Replace the filter (fig. 3). To clean a water filter It is vital to clean and descale regularly in order to maintain good working order We recommend using white vinegar as follows: • Pour into kettle about 50 gr. or 2 oz. of white vinegar and then fill with water up to the max level indicated and then boil. Allow the contents to cool, and then rinse thoroughly. • Do not use a more concentrated solution. If the filter requires descaling, remove the filter and place into the white vinegar solution in the kettle. • Ensure that the electrical connections are completely dry before using the kettle. 8

Scale
Scale is mainly calcium carbonate (chalk), a harmless, naturally occurring mineral found in most
water supplies. “Hard” water contains more of this mineral than “soft” water.
When the water is heated, the minerals in the water solidify, making the water appear cloudy.
These minerals form a thin film on the walls, element and on the surface of the water. The water
may look like it has white colored pieces of plastic floating on the surface.
On traditional kettle elements, scale forms a hard white “crust” which adversely affects
performance and reduces the life of the element.
As soon as you notice a
film
forming on the water, or, when cleaning the filter, if you notice a
film on the walls or the element, simply rinse the kettle and wipe it out.
Water filter
Your kettle is fitted with a water filter to prevent loose particles of scale being poured into your
beverage. This filter is both removable and washable.
The frequency with which you will need to clean any scale deposits from your filter will depend
on the hardness of water in your area and how often you use the kettle.
You should remove and clean the water filter when you notice any deposits being left on the filter
or if the pouring efficiency is impaired.
Removing the water filter
•
Allow the kettle to cool down completely.
•
Disconnect the appliance from the outlet.
•
Make sure that your hands are clean and free from soap, cream or anything which might
taint the water.
•
Empty the kettle and remove the water filter as shown in fig. 1.
