Installation Guidelines
Ambient Temperature Conditions
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.
Operation temperature :
Max. ambient temperature : 40 °C (104°F)
Min. ambient temperature : 0 °C (32°F).
The projector will not operate if ambient air temperature falls outside this range (0°C- 40°C) (32°F-104°F).
Storage temperature : -35 °C to + 65 °C (-25.6°F to 149°F)
Humidity Conditions
Storage : 0 - 98% RH Non-condensing
Operation : 0 - 95% RH Non-condensing
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.
Special care for Laser beams
Special care should be used when DLP projectors are used in the same room as performant laser equipment. Direct or indirect hitting
of a laser beam on to the lens can severely damage the Digital Mirror Devices (TM) in which case there is a loss of warranty
Which screen type?
There are two major categories of screens used for projection equipment. 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) or
more. The choice between higher and lower gain screens is largely a matter of personal preference and another consideration called
the Viewing angle.
In considering the type of screen to choose, determine where the viewers will be located and go for the highest gain screen possible.
A high gain screen will provide a brighter picture but reduce the viewing angle.
