effective UV radiation. An evaluation of the workplace is advised to assure employees are not exposed to
cumulative radiation levels exceeding these government guidelines.

3.3 To prevent fire hazard

Fire Hazard
• Barco projection products are designed and manufactured to meet the most stringent safety regulations.
This projector radiates heat on its external surfaces and from ventilation ducts during normal operation,
which is both normal and safe. Exposing flammable or combustible materials into close proximity of this
projector could result in the spontaneous ignition of that material, resulting in a fire. For this reason, it is
absolutely necessary to leave an "exclusion zone" around all external surfaces of the projector whereby no
flammable or combustible materials are present. The exclusion zone in the exhaust area must be not less
than 100 cm (40"). The exclusion zone on the intake area must not be less than 50 cm (20"). The exclusion
zone on the lens side within the light beam must be at least 1,5 m.
• Do not place flammable or combustible materials near the projector!
• Slots and openings in this equipment are provided for ventilation. To ensure reliable operation of the
projector and to protect it from overheating, these openings must not be blocked or covered.
• .The openings should never be blocked by placing the projector too close to walls, or other similar surface.
Allow for sufficient distance to walls and ceilings to avoid overheating. Minimum safety distance to the
exhaust area of the unit must not be less than 100 cm (40") and to the intake area, not less than 50 cm
(20").
• This projector should never be placed near or over a radiator or heat register.
• This projector should not be placed in a built-in installation or enclosure unless proper ventilation is
provided.
• Do not cover the projector or the lens with any material while the projector is in operation. Keep flammable
and combustible materials away from the projector at all times.
• Mount the projector in a well-ventilated area away from sources of ignition and out of direct sun light.
• Never expose the projector to rain or moisture. In the event of fire, use sand, CO2 or dry powder fire
extinguishers.
• Never use water on an electrical fire.
• Always have service performed on this projector by authorized Barco service personnel. Always insist on
genuine Barco re- placement parts. Never use non-Barco replacement parts as they may degrade the
safety of this projector.
• Projection rooms must be well ventilated or cooled in order to avoid heat buildup.
• Let the projector cool down completely before storing. Remove cord from the projector when storing.

3.4 To prevent projector damage

Preventing Projector Damage.
• To ensure correct airflow is maintained, and that the projector complies with Electromagnetic Compatibility
(EMC) requirements, it should only be operated when all of its covers in place.
• Always remove lens cap before switching on the projector. If the lens cap is not removed, it may melt due
to the high energy light emitted through the lens. Melting the lens cap will permanently damage the surface
of the projection lens.
• The projector must always be installed in a manner, which ensures free flow of air into its air inlets and
unimpeded evacuation of the hot air from its cooling system.
• Slots and openings in the cabinet are provided for ventilation. To ensure reliable operation of the product
and to protect it from overheating, these openings must not be blocked or covered. The openings should
never be blocked by placing the product on a bed, sofa, rug, or other similar surface. This product should
never be placed near or over a radiator or heat register. The device should not be placed in a built-in
installation or enclosure unless proper ventilation is provided. Ensure that nothing can be spilled on, or
dropped inside the projector. If this does happen, switch off and unplug the mains supply immediately. Do
not operate the projector again until it has been checked by BARCO authorized service personnel..
• Do not block the projector cooling fans or free air movement around the projector. Minimum safety distance
to the exhaust area of the unit must not be less than 100 cm (40") and to the intake area, not less than 50
cm (20")
• Do not use this equipment near water.
