Operation Manual

Coffee variations
A strong coffee, made with the Mocha Coffee Maker MC10 espressiva by
petra-electric, can be prepared in many different variations: e.g.
Coffee mocha - with liquid chocolate, hot milk and cream
Caramel macchiatto - with hot, frothed milk, vanilla flavour and caramel
Coffee coretto - with one shot of aniseed brandy, sambuca, ama-
retto, grappa or fernet brandies
Safety system
The safety valve (6) protects the appliance from too much pressure.
Therefore it must not be manipulated. The security performance of the
valve is not ensured if the appliance is operated with too much water.
In case of erroneous operation without water, a thermostat protects the
appliance from overheating by switching off the heating. After cooling down
the appliance is again operational.
If the first thermostat fails in case of improper use, an additional tempera-
ture control ensures a reliable protection.
De-scaling
Lime scales cause loss of energy and reduce the life time of the appliance.
Therefore, the container should regularly be de-scaled with usual de-
scaling agents suitable for stainless steel. Please consider the user
instructions of the manufacturer.
Only heaten the substance in open container, it must not boil, otherwise it
will foam over the top of the kettle. After de-scaling rinse carefully with
water.
Guarantee does not cover damages resulting from non-observance of the
manufacturers instructions.
Cleaning and maintenance
Before cleaning unplug the appliance and let it cool down. Never immerse
the heating vessel into water. The single components are not dishwasher-
proof. Clean the outside of the appliance with a damp cloth only.
All metal components are made from rust-resistant stainless steel. Any iron
moulds are only residues which stick on the surfaces. They can be
removed with a special polishing agent for stainless steel. Do not use any
caustic or scouring cleaning agents.
