OTHER CLEANING OPERATIONS

1.Do not use solvents or abrasive cleaning products to clean the appliance. A soft, damp cloth is sufficient.

2.Remove the drip tray, empty and wash frequently.

3.Clean the water tank regularly.

IMPORTANT: during cleaning, never immerse the coffee machine in water. It is an electrical appliance.

DESCALING

You are recommended to descale the coffee machine about every 200 coffees.

You should use a commercially available product specifically for descaling espresso coffee machines.

If such a product is not available, proceed as follows.

1.Fill the tank with one litre of water.

2.Dissolve 2 spoonfuls (about 1 ounce) of citric acid.

3.Rotate the selector knob to the position and wait until the OK indicator light comes on.

4.Make sure the filter holder is not attached and position a container under the boiler outlet.

5.Rotate the selector knob to the position (fig. 8) and run off half the solution in the tank.

Then interrupt the flow by rotating the selector to the "O" position (fig. 14).

6.Leave the solution to work for about 15 minutes, then run off the rest of the water in the tank.

7.To eliminate residues of solution and scale, rinse the tank well, fill with clean water and replace.

8.Rotate the selector knob to the position (fig. 8) and run off the water until the tank is completely

empty;
9 Rotate the selector knob to the	position (fig. 5)

and repeat operations 7 and 8 again.

Repair of damage to the coffee machine caused by scale is not covered by the resulting unless descaling is performed regularly as described above.
