Preparing Coffee; Cleaning And Maintenance - Petra electric KM 99 Gebrauchsanweisung

Preparing coffee

Fill in cold water into the water container.
The water level indication shows the
number of brewed cups with 125 ml of
coffee each. Swivel the filter holder for-
wards and insert a paper filter 1 x 4 with
the filter folder along the embossed line.
Fill in the necessary quantity of coffee.
Use approximately 5-7 grams of medi-
um fine ground coffee per cup or accor-
ding to personal preference.
Put the thermal jug with the closed
brewing lid under the filter. Connect
plug with a safety socket and switch on.
The operation lamp shows the start of
the brewing process. After the end of
the flow, the appliance switches off
automatically, the control lamp goes
out. After detaching the jug, the non-
drip system in the filter avoids that the
coffee drips.
Before making new coffee, the appliance
has to cool down for some minutes.
Soluble coffee can be used in the filter
without paper.
Prepare tea by hanging the tea bags
into the jug. Thereby, the filter is to be
placed into the filter holder.

Cleaning and maintenance

Disconnect the appliance from the
socket and let the coffeemaker cool
down. Never immerse the appliance and
the thermal jug in water. Use a damp
cloth with washing-up liquid only and
rub dry afterwards.
The filter can be cleaned under running
water or in a dishwasher. Rinse the jug
with warm water only after every use. It
must not be put into a dishwasher.
In case that after some time there is a
layer inside the thermal jug, you can use
a pill suitable for cleaning dentures to
get it off. Fill in water plus the pill, and
leave it for some hours. Then rinse it
several times.
Do not use any scouring and abrasive
agents.
Descaling
Like other hot-water appliances, the cof-
fee maker has to be descaled regularly,
at the latest in case of a considerable
longer brewing time and a higher noise
level.
If you do not observe these conditions,
it could be the possibility that the appli-
ance switches off although the water
has not passed completely.
The following indications are guidelines
which refer to a daily use in the house-
hold.
You can ask for the degree of hardness
in your residential area at the responsible
waterworks or the local administration.
Degree of Descaling
hardness intervals
1 water with
descale twice
low calcium
a year
content
2 water with descale four
medium times a year
calcium content
3 4 water with high descale
and
calcium content monthly
Use a standard descaling agent accor-
ding to the application instructions.
Place the paper filter and put the jug in
the coffee maker. Pour approx. 1 l des-
caling agent, diluted or dissolved accor-
ding to the application instructions into
the water container.
If the appliance is disconnected several
times for some minutes during the
brewing process, the descaling agent
can work at best.
Repeat this process with a new desca-
ling agent each until the disturbing noise
is removed.
Never pour hot descaling solution into
the water container.
Attention: After descaling it is neces-
sary to operate the appliance 2 times
with a full container of water as done
before the first use.
Damages caused by the non-observan-
ce of these instructions are not covered
by the guarantee.
