Maintenance
• When unpacking, installing and cleaning
your fixture, handle the individual
components with outmost care,
particularly the glass parts, which are
very fragile.
• Assembly and electric installation must
be carried out by certified electricians.
• Table lights are intended for interiors.
• Do not cover nor touch the light source
while the light is on.
• Do not attempt any repairs or changes
to the components. Always contact our
specialized service.
• Spare parts that are not supplied or
approved by the producer may not be
used (with the exception of light sources
replacement).
• Do not expose the light fixture to
unsuitable environments where it could
become damaged (water, frost, heat).
• Ensure appropriate access prior to
maintenance or cleaning table lights, in
order to comfortably reach and safely
handle the light fixture.
• Note: in some areas, the lighting fixture
may have sharp edges that may cause
injury. Beware while in immediate
proximity of the fixture.
• Perform cleaning and all maintenance
with the light turned off, ideally entirely
disconnected. Respect this rule for the
entire duration of installation.
• When changing a light bulb, always
disconnect the light fixture from its power
supply.
• We recommend performing the
installation of table lamps with one
person.
• After installation check whether the light
fixture is properly set in its base.
• Do not expose the light to inappropriate
strain and protect it from mechanical
damage.
• When in operation, the light source
becomes hot. Prior to any handling, wait
for the light source to naturally cool down
and do not expose it to fast cooling.
• Halogen light sources may not come in
contact with greasy materials, so do not
touch them with bare hands. Install them
using clean textile gloves or tea towels.
When cleaning halogen bulbs, it is best to
use alcohol-based cleaners.
• When changing a bulb, use the same or
recommended light source. Information
regarding the type appears both on the
label and in the installation manual.
• Do not hang any other components on
the light fixture, other than those listed in
the installation manual.
• Pay attention to checking all parts prior to
their installation. Damaged components
and glass parts (fragmentation, cracks)
may cause personal injuries to persons
moving within its proximity.
• Should any serious problem occur during
cleaning or maintenance, do not hesitate
to contact the producer.
• Any other handling of the table light
fixture should be performed by a
qualified technician or directly by the
producer.

Cleaning
• All cleaning and maintenance must be
carried out when the power is off, ideally
entirely disconnected.
• When cleaning, use fine-fabric gloves.
Particularly avoid handling metal-
coated crystal without gloves to avoid
fingerprints and loss of gloss.
• Use soft cloths to clean metal parts. Such
parts may be cleaned with a dry cloth or
a cloth dampened in warm water with a
mild detergent. Avoid the use of solvents
or technical benzene to clean metal
parts. Avoid alcohol-based cleaners that
may cause changes of surface colors.
• Clean light bulb using a soft dampened
cloth, antistatic brush with soft bristles or
a vacuum cleaner turned to low mode.
• Clean fine-steel surfaces with products
sold especially for this purpose.
• To clean the glass parts, use products in
concentrations recommended by their
producers. Immediately after cleaning,
dry the light fixture and hang it again.
• When cleaning glass parts, a
concentrate of 90% water and 10%
vinegar may also be used. Fill up a clean
• spray-bottle with this mixture. Use
cotton gloves, apply the solution to
one of them and gently wipe the parts
requiring cleaning. Immediately dry
the cleaned surfaces with the other
glove. Give particular care to cleaning
individual parts of the light that cannot
be dismantled. Inappropriate handling
may cause loosening or chipping of
these parts.
• Avoid cleaning removable parts of the
light fixture in a dishwasher.
Important notice
• The producer bears no responsibility
for damage caused by unprofessional
installation or inappropriate handling
of the light fixture, including installation
with accessories other than those
recommended by the producer.
• The producer bears no responsibility
for damage caused by unprofessional
interventions into the mounting and
safety features of the light fixture,
including damage to the product by
inappropriate power supply, storage
or use of the light fixture in a humid
environment.
• Do not place the light fixture in humid
environments, such as near a boiler or
other sources of water vapor. Do not
place the lighting fixtures in shower
enclosures or above bathtubs and never
touch them when you are in contact with
water.
• The producer reserves the right to make
minor changes to the construction of the
light fixture without prior notice.
