Decalcification

Calcification display

The appliance must be routinely decalcified as all

hot water appliances.

The automatic calcification display determines the

time for the required decalcification. Depending on

the coffee consumption, you will already be required

to perform decalcification after 6 to 10 weeks by the

yellow flashing on/off button (10).

You may continue to brew coffee and prepare hot

water. However, milk frothing is no longer possible.

Hardness range setting

The appliance is preset to very hard water (hardness

range 4) as a precaution against excessive calcificati-

on. Request the hardness range in your residential

area from the responsible waterworks or the commu-

nity administration. If it is lower than 4, you can chan-

ge the setting. You then must no longer decalcify so

frequently.

1. Switch the appliance off at the on/off button (10).

2. Press the start/stop button (12) (3 to 4

seconds) until the on/off button (10) flashes yel-

low. The number of impulses shows the set

hardness range.

Flashing signal Hardness range Hardness

· · · 1 soft 0 - 7° dH

· · · · · · 2 medium > 7 - 14° dH

· · · · · · · · · 3 hard > 14 - 21° dH

· · · · · · · · · · · · 4 very hard > 21° dH

1° dH corresponds with approx. 0.18 mmol/l Ca- and Mg

ions

3. You will change the setting by one step every time

you press the start/stop button (12). Range 1 fol-

lows hardness range 4 again.

4. In order to assume the new hardness range, press the

on/off button (10) again briefly, if this is not done

within 10 seconds, the appliance is switched off with-

out changing the setting. You can check the hardness

range at any time by repeating step 1 and 2.

Decalcifier

The automatic decalcification program of your auto-

matic coffee pad appliance is optimized to be used

for a portion (125 ml) of durgol

swiss espresso

Therefore only use this product in the specified quan-

tity when decalcifying the appliance. A complete

decalcification and saving the materials is only gua-

ranteed during the brief decalcification period.

durgol

swiss espresso

was specifically develo-

ped for automatic coffee and espresso machines. It

is used undiluted, is highly effective and guarantees a

reliable decalcification and therefore a long service

life of the appliance.

Never use vinegar or vinegar concentrate since

material of the appliance might be damaged.

Decalcification with citric acid is too slow. That is

why a proer decalcification cannot be guaranteed.

A warranty claim does not exist for damages that

develop due to the use of an unsuitable decalcifier or

non-compliance of the decalcification specifications.

Please be careful when carefully handling the

decalcifying agent that damages are not caused on

furniture or clothing. Please use a possibly high cup

for that reason and place it under the respective

spout in order to prevent splatters.

Decalcification program

Your automatic coffee pad system includes an automatic

decalcification program that lasts approximately for 25 to

30 minutes. Its first segment consists of 3 decalcification

cycles. The decalcifying agent is rinsed out with tap water

during the subsequent second segment within 7 passes.

Note: Once the automatic decalcification program is

started, it cannot be interrupted.

If necessary, you may pull the power supply plug.
