To Prevent Fire Hazard; To Prevent Projector Damage - Barco F90 Service Manual

3. Important Safety Instructions
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.

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.
• Special care for Laser Beams: Special care should be used when DLP projectors are used in the same room as high power
laser equipment. Direct or indirect hitting of a laser beam on to the lens can severely damage the Digital Mirror Devices™ in
which case there is a loss of warranty.
• Never place the projector in direct sun light. Sun light on the lens can severely damage the Digital Mirror Devices™ in which
case there is a loss of warranty.
• Save the original shipping carton and packing material. They will come in handy if you ever have to ship your equipment. For
maximum protection, repack your set as it was originally packed at the factory.
• Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for
cleaning. Never use strong solvents, such as thinner or benzine, or abrasive cleaners, since these will damage the cabinet.
Stubborn stains may be removed with a cloth lightly dampened with mild detergent solution.
• To ensure the highest optical performance and resolution, the projection lenses are specially treated with an anti-reflective
coating, therefore, avoid touching the lens. To remove dust on the lens, use a soft dry cloth. Do not use a damp cloth, detergent
