About this chapter
Read this chapter before installing your MSWU-81E projector. It contai ns important information concerning i nstallation
requirements for the MSWU-81E projector, such as minimum an d maximum allowed ambient temperature, humid ity
conditions, required safety area around the installed projector, required power net, etc.
Furthermore, careful consideration of thing s such as image size, ambient light level, projector pla cement and type of screen
to use are critical to the optimum use of the projecti on system.

performance. Neglecting this can res ult in loss of warranty.

2.1 Installation requirements

Environment conditions
Table below summarizes the physical environment in whi ch the MSWU-81E projector may be safely operated or stored.
Environment Operating Non-Operating
Ambient Temperature
Humidity
Altitude
10 °C (50 °F) to 40 °C (104 °F)
5% to 85% RH Non-condensed
-60 (-197Ft) to 3000m (9843Ft)
-15°C (5°F) to 60°C (140°F)
5% to 95% RH Non-Condensed
-60 (-197Ft) to 10000m (32810Ft)
Let the projector acclimatize after unpacking . Neglecting this may result in a startu p failure of the Light
Pro- cessor Unit.
Cooling requirements
The projector is fan cooled and must be inst alled with sufficient space around the proje ctor head, minimum 30 cm (12 inch)
to ensure sufficient air flow. It should be used in an area where the a mbient temperature, as measured at the projector air
inlet , does not exceed +40°C (+104°F).
Clean air environment
A projector must always be mounted in a manner wh ich ensures the free flow of clean air into the projectors ve ntilation
inlets. For installations in environment s where the projector is subject to airbo rne contaminants such as that produced
by smoke machines or similar (these deposit a thin layer of greas y residue upon the projectors internal optic s and imaging
electronic surfaces, degrading p erformance), then it is highly advisable and de sirable to have this contamination removed
prior to it reaching the projectors clean air supp ly. Devices or structures to extract or shield co ntaminated air well away
from the projector are a prerequisite, if this is not a feasible so lution then measures to relocate the projector to a clean air
environment should be considered.
Only ever use the manufacturer’s recommended c leaning kit which has been specifically d esigned for cleaning optical parts,
never use industrial strength cleaners on the p rojector’s optics as these will degrade opti cal coatings and damage sensitive
optoelectronics components. Failure to take suit able precautions to protect the projector fro m the effects of persistent and
prolonged air contam- inants will culmi nate in extensive and irreversible ingrained o ptical damage. At this stage cleaning of
the internal optical units will be noneffe ctive and impracticable. Damage of t his nature is under no circumstances covered
under the manufacturer’s warranty an d may deem the warranty null and void. In suc h a case the client shall be held solely
responsible for all costs incurred durin g any repair. It is the clients responsibility to ensure at all ti mes that the projector
is protected from the harmful effects of hos tile airborne particles in the envi ronment of the projector. The manufacturer
reserves the right to refuse repair if a projector has b een subject to knowingly neglect , abandon or improper use.
