INSTALLATION GUIDELINES
Installation Guidelines
Careful consideration of things such as image size, ambient light level, projector placement and type of screen to use are critical to the optimum
use of the projection system.
* Environment
Do not 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.
* Environment condition check
Warning: Harmful Environmental Contamination Precaution
A projector must always be mounted in a manner which ensures the free flow of clean air into the projectors ventilation inlets. For installations
in 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 air supply. Devices or structures to extract
or shield contaminated air well away from the projector are a prerequisite, if this is not a feasible solution then measures to relocate the projector
to a clean air environment should be considered.
Only ever use the manufactures recommended cleaning kit which has been specifically designed for cleaning optical parts, never use industrial
strength cleaners on a projectors optics as these will degrade optical coatings and damage sensitive optoelectronic components. Failure
to take suitable precautions to protect the projector from the effects of persistant and prolonged air contaminants will culminate in extensive
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 manufactures warranty and may deem the warranty null and void. In such a
case the client shall be held solely 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 particles in the environment of the projector. The manufacture reserves
the right to refuse repair if a projector has been subject to wantful neglect, abandon or improper use.
* What about ambient light ?
The ambient light level of any room is made up of direct or indirect
sunlight and the light fixtures in the room. The amount of ambient light
will determine how bright the image will appear. So, avoid direct light
on the screen.
Windows that face the screen should be covered by opaque drapery
while the set is being viewed. It is desirable to install the projection
system in a room whose walls and floor are of non-reflecting material.
The use of recessed ceiling lights and a method of dimming those
lights to an acceptable level is also important. Too much ambient light
will ‘wash out’ of the projected image. This appears as less contrast
between the darkest and lightest parts of the image. With bigger
screens, the ‘wash out’ becomes more important. As a general rule,
darken the room to the point where there is just sufficient light to read
or write comfortably. Spot lighting is desirable for illuminating small
areas so that interference with the screen is minimal.
Max. ambient temperature : 40 °C or 104 °F
Min. ambient temperature : 0 °C or 32 °F
The projector will not operate if ambient air temperature falls outside this range (0°C- 40°C or 32°F-104°F).
