SAFETY PRECAUTIONS
IMPORTANT SAFEGUARDS
When using electrical appliances, basic safety
precautions should always be followed including the
following:
READ ALL INSTRUCTIONS
• Make sure the voltage of your electrical system
corresponds to the voltage shown on the machine.
• Do not touch hot surfaces. Use handles or knobs.
• To protect against electrical shock, do not immerse
cord or plug in water or other liquid.
• Close supervision is necessary when any appliance
is used by or near children.
• Unplug from outlet when not in use and before
cleaning. Allow to cool before putting on or taking
off parts.
• Do not operate any appliance with a damaged cord
or plug, or after the appliance malfunctions or has
been damaged in any manner. Return appliance to
the nearest authorized service facility for examination, repair or adjustment.
• The use of accessory attachments not recom-
mended by the appliance manufacturer may cause
injuries.
• Do not let cord hang over edge of table or counter,
or touch hot surfaces.
• Do not place on or near a hot gas or electric
burner, or in a heated oven.
• Extreme caution must be used when moving an
appliance containing hot oil or other hot liquids.
• To disconnect, turn any control to “off”, then
remove plug from wall outlet.
• Do not use appliance for other than intended use.
• The appliance must be properly installed before
operation to ensure that no electrical components
are accessible. Ensure that power is not supplied
to the appliance while installation work, repairs or
maintenance is performed.
• Be certain your appliance is properly installed and
grounded by a qualied technician. To guarantee
the electrical safety of this appliance, continuity
must exist between the appliance and effective
grounding system. It is imperative that this basic
safety requirement be met. If there is any doubt,
have the electrical system of the house checked by
a qualied electrician. The manufacturer can not be
held responsible for damages caused by the lack,
or inadequacy, of an effective grounding system.
• Do not use an extension cord to connect the appli-
ance to electricity. Extension cord doesn’t guarantee the required safety of the appliance (danger
of overheating).
• Installation work and repairs must be only per-
formed by a trained technician in accordance with
national and local safety regulations. Repairs and
other work by unauthorized persons could be dangerous and may void the warranty.

SAFETY PRECAUTIONS
IMPORTANT SAFEGUARDS
• Only use original spare parts. Only then can the
manufacturer guarantee the safety of this machine.
• Never open the outer casing of the appliance.
Tampering with electrical connections or
components and mechanical parts is dangerous
and may cause machine damage.
• If the machine is installed in combination with other
appliances, a protective base should be installed
between the appliance and the unit.
• Do not install or use outdoors even if installed in
the display cabinet.
• Only ll the water tank with cold, fresh tap water.
Warm or hot water, or any other liquids may
damage the machine.
• The water should be changed daily to prevent bac-
teria or mold growth.
• Do not use mineral water. Mineral water leads to
heavy calcium buildup in the machine that can
damage the unit.
• Do not ll anything but coffee beans into the beans
container. Do not ll ground coffee in the beans
container, it will damage the grinding unit.
• Never place a cup with an alcohol-coffee mixture
underneath the coffee dispenser. Plastic parts of
the unit could catch re!
• The hot water and steam dispensed could cause
scalding. These functions must be used carefully.
Never hold any parts of the body under the steam
nozzle or the hot water dispenser. The machine
must never be used to clean objects.
• Never use a steam cleaner to clean the appliance.
Pressurized steam could damage electrical components and cause a short circuit.
• The appliances must be descaled regularly. In
areas with very hard water the machine may need
to be descaled more often. The manufacturer
cannot be held responsible for damages resulting
from insufcient descaling.
• Never make coffee, hot water or steam when the
appliance is extracted. Always make sure the
appliance is inactive before extracting it. Failure to
observe this precaution could lead to damage to
the appliance! The only exception is adjusting the
coffee mill which must be done with the machine
out (see the section “Coffee Mill”).
• Sugar can damage the appliance! Caramelized
or otherwise pre-treated coffee beans or other
sugar containing beverages must not be put in the
machine.
