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.

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.

You may obtain it where you bought the appliance;

directly from a select dealer or you can order it direct-

ly from petra-electric.

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

minutes.

Note: Once the automatic decalcification program is

started, it cannot be interrupted.

steam outlet (22). Use the Allen key (32) for this, it

is located on the bottom of the drip pan (8).

3. Fill a portion (125 ml) of durgol

swiss espres-

into the empty water reservoir (4), place the
