2. Installation Guidelines2. INSTALLATION GUIDELINESOverview• Installation guidelines• Configuration• Lenses• BatteriesBefore installing the projector, read first the safety instructions supplied with the BARCOREALITY SIM6 UL-TRA.2.1 Installation guidelinesAmbient Temperature ConditionsCareful consideration of things such as image size, ambient light level, projector placement and type of screen to use are critical tothe optimum use of the projection system.Max. ambient temperature : 40 °C or 104 °FMin. ambient temperature : 0 °C or 32 °FThe projector will not operate if ambient air temperature falls outside this range (0°C- 40°C or 32°F-104°F).Storage temperature: -35°C to +65°C (-25.6°F to 149°F)Humidity ConditionsStorage: 0 to 98 % RH Non-condensingOperation: 0 to 95 % RH Non-condensingEnvironmentDo 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 notexcessive.Harmful Environmental Contamination PrecautionEnvironment condition checkA projector must always be mounted in a manner which ensures the free flow of clean air into the projectors ventilation inlets. Forinstallations in environments where the projector is subject to airborne contaminants such as that produced by smoke machines orsimilar (these deposit a thin layer of greasy residue upon the projectors internal optics and imaging electronic surfaces, degradingperformance), then it is highly advisable and desirable to have this contamination removed prior to it reaching the projectors cleanair supply. Devices or structures to extract or shield contaminated air well away from the projector are a prerequisite, if this is not afeasible 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, neveruse industrial strength cleaners on a projectors optics as these will degrade optical coatings and damage sensitive optoelectroniccomponents. Failure to take suitable precautions to protect the projector from the effects of persistent and prolonged air contami-nants will culminate in extensive and irreversible ingrained optical damage. At this stage cleaning of the internal optical units will benon-effective and impracticable. Damage of this nature is under no circumstances covered under the manufactures warranty andmay deem the warranty null and void. In such a case the client shall be held solely responsible for all costs incurred during anyrepair. It is the clients responsibility to ensure at all times that the projector is protected from the harmful effects of hostile airborneparticles in the environment of the projector. The manufacture reserves the right to refuse repair if a projector has been subject towantful 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 ambientlight will determine how bright the image will appear. So, avoid direct light on the screen. Windows that face the screen should becovered by opaque drapery while the set is being viewed. It is desirable to install the projection system in a room whose walls andfloor are of non-reflecting material.
