o During use of the coffee machine, depending on the hardness of the local water supply
internal parts of the unit can become covered in calcium deposits. In order to maintain
the unit in the best possible condition and ensure the best possible results from each
brewing cycle it is necessary to clean the unit of deposits from time to time.
o Under conditions of heavy use the coffee machine must be cleansed of calcium
deposits every two weeks, as well as cleansed of oils, stains from coffee, and other
heavy residues.
o For cleaning use commercially available coffee maker cleaning agents.
o You should also the deposit removal process the coffee machine when the brewing
process starts taking longer, when the brewing sounds get louder or in case the
coffee machine shuts off although there is still water in the tank (e.g. in case of very
hard water).

coffee machines" a formula tried and tested by us:
(Code-No.: 190065; packaged in 30 portions of 15 g/each).
o Dissolve the calcium deposit removal formula (15g) in 1-2 litres of water.
o Pour the solution containing the calcium deposit removal formula to the water tankfor
the coffee machine.
o Insert the filter basket by sliding it along the appropriate guides (without coffee).
o Place the empty thermo jug on the bottom plate under the filter basket.
o Turn the unit on as for normal use.
o After several drops of the solution have flowed into the thermo jug, turn the coffee
machine off.
o Wait 5-6 minutes for the remainder of the solution to dissolve the deposits, then turn
the unit on again.
o After the entire solution has flowed through the machine, turn the coffee machine off
and dispose of the solution.
o After finishing the deposit removal process it is necessary to repeat the brewing
process 2-3 times using only water, in accordance with the instructions contained in
this insert and/or instructions for use. Water remaining in the coffee machine must
then be removed with the help of the flow valve located on the rear wall (at the
bottom) of the unit.
