IMPORTANT INSTRUCTIONS
READ ALL INSTRUCTIONS
When using electrical appliances, basic safety
precautions should always be followed including
the following:
• Make sure the voltage of your electrical system
corresponds to the voltage shown on the
machine.
• Persons that lack physical, sensory, or mental
abilities or experience with the machine should
not use it without supervision or instruction by
a responsible person.
• Before service or maintenance, disconnect
power at the main button and unplug the unit.
• 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 appli-
ance is used by or near children.
• Do not open the outer casing of the appliance.
• Unplug from outlet when not in use and prior
to cleaning. Allow to cool before putting on or
taking o 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.
• Do not place on or near a hot gas or electric
burner or in a heated oven.
• The use of accessory attachments not recom-
mended by the appliance manufacturer may
cause injuries.
• Do not allow the cord to hang over the edge of
a table or counter or touch hot surfaces.
• Do not submerge the cord or plug in water or
other liquids.
• Use extreme caution when moving an appli-
ance containing hot oil or other hot liquids.

Safety Precautions
IMPORTANT INSTRUCTIONS
GENERAL SAFETY PRECAUTIONS
• Do not use appliance for anything other than
intended use.
• The appliance must be properly installed prior
to operation to make sure no electrical com-
ponents are accessible. Make sure power is
not supplied to the appliance while installation
work, repairs, or maintenance is done.
• A short power cord is provided to reduce risks
of becoming entangled or tripping over the
cord.
• Verify the appliance is properly installed and
grounded by a qualified technician. To guar-
antee the electrical safety of this appliance,
continuity must exist between the appliance
and eective grounding system. It is imperative
this basic safety requirement be met. If there
is any doubt, have the electrical system of the
house checked by a qualified electrician. The
manufacturer cannot be held responsible for
damages caused by the lack, or inadequacy, of
an eective grounding system.
• Do not use an extension cord to connect the
appliance to electricity. Extension cord does
not guarantee the required safety of the appli-
ance (danger of overheating).
Safety Precautions
• Installation work and repairs must be done by a
trained technician in accordance with national
and local safety regulations. Repairs and other
work by unauthorized persons could be dan-
gerous and may void the warranty.
• Use only 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 com-
ponents and mechanical parts is dangerous and
may cause machine damage.
• Do not install or use outdoors.
• Never use a steam cleaner to clean the appli-
ance.
• Fill the water tank only with cold, fresh tap
water. Warm or hot water or any other liquids
may damage the machine.
• The appliance must be maintained daily.
Change the water daily to prevent bacteria or
mold growth.

penser. Never use the machine to clean objects.
• Descale the appliance regularly with descal-
ing solution. In areas with very hard water, the
machine may need to be descaled more often.

for damages resulting from insucient descal-
ing.
• Never make coee, hot water, or steam when
the appliance is removed from the opening.
