Barco R9010320 2.3 Projector Configuration

2. Installation Guide lines

Donot install the projection system in a site near heat sources such as radiators or air ducts, or in a place subject to direct sunlight,

excessive dust or humidity. Be aware that room heat rises to the ceiling; check that temperature near the installation site is not

excessive.

Aproject ormust always bemounted in a mannerwhich ensuresthe freeflow of clean air into the projectors ventilationinlets. For

installationsin environments where the projector is subject to airborne contaminants such as that produced by smoke machines or

similar(these deposit a thin layer of greasy residue upon the projectors internal optics and imaging electronic surfaces, degrading

performance),then it is highly advisable and desirable to have this contamination removed prior to it reaching the projectors clean

airsupply. D evices or structures to extract or shield contaminated air well away from the projector are a prerequisite, if this is not a

feasiblesolution then measures to relocate the projector to a clean air environment should be considered.

Onlyever use the manufacturer’s recommended cleaning kit which has been specifically designed for cleaning optical parts, never

useindustrial strength cleaners on the projector’s optics as these will degrade optical coatings and damage sensitive optoelectronics

components. Failure to take suitable precautions to protect the projector from the effects of persistent and prolonged air contam-

inants will culminate inextensive and irreversible ingrained optical damage. At this stage cleaning of the internal optical units will

be non-effective and impracticable. Damage of this nature is under no circumstances covered under the manufacturer’s warranty

andmay deem the warranty null and void. Ins uch a case the client shall be heldsolely responsible for all costs incurred during any

repair. It is the clients responsibility to ensure at all times that the projector is protected from the harmful effects of hostile airborne

particlesin the environment of the projector. Themanufacturer reserves the right to refuse repair if a projector has been subject to

wantful neglect, abandon or improper use.

Specialcare should be used when DLP projectors are used in the same room as performant laser equipment. Director indirect hitting

ofa laser beam on to the lens can severe ly damage the Digital MicroMirror Devices™ in which case there is a loss of warranty

Thereare two major categories of screens used for projection equi pment. Those used for front projected images and those for rear

projection applications.

Screens are rated by how much light they reflect (or transmit in the case of rear projection systems) given a determined amount

of light projected toward them. The ‘GAIN’ of a screen is the term used. Front and rear screens are both rated in terms of gain.

The gain of screens range from a white matte screen with a gain of 1 (x1) to a brushed aluminized screen with a gain of 10 (x10)

ormore. The choice between higher and lower gain screens is largely a matter of personal preference and another consideration

calledthe Viewing angle. In considering the type of screen to choose, determine where the viewers will be located and go for the

highestgain screen possible. A high gain screen will provide a brighter picture but reduce the viewing angle. For more information

about screens, contact your local screen supplier.

The projector is designed for projecting an image size : min 1.00m (3.3ft) to max 15 m (49.2ft) (depending on the ambient light

conditions), with an aspect ratio of 4 to 3.

2.3 Projector Configuration

The projectorcan be installed to project images in four different configurations:

• Front/table

• Rear/table

• Front/ceiling

• Rear/ceiling

Theprojector should be installed perpendicular with the screen on a distance PD and water leveled in both directions. Themounting

positions in the following images are shown for a nominal lens position.
