User maintenance — Cleaning the projector

14.1 Projector lenses

General guidelines for cleaning projector lenses
Blow off dust with clean compressed air (or pressurized air cans) .
Use lens cleaner and a clean lens cleaning cloth to remove the dust and contamination.
Wipe in broad strokes, in one direction only.
Warning: Do not wipe back and forwards across the lens surface as this tends to grind dirt into the coating.
Use a dry clean lens cleaning cloth to remove left liquid or stripes. Polish with small circles.
If there are still fingerprints on the surface, repeat with lens cleaner and a clean lens cleaning cloth, then polish
again with a dry cloth.
If smears occur when cleaning lenses, replace the cloth. Smears are the first indication of a dirty
cloth.

14.2 Projector cabinet

WARNING: Always disconnect the projector from the mains power net before attempting to clean
the projector cabinet.
General guidelines for cleaning the projector cabinet (exterior only)
Clean the housing of the projector with a damp cloth. Stubborn stains may be removed with a cloth lightly
dampened with a mild detergent solution.

14.3 Filters

General info regarding Air intake and filters.
The product is shipped default without any filters and by avoiding filters, the ventilation system operates for
longer periods between maintenance, since no clogging of filters means more air is allowed through the
system, resulting in lower operating temperatures over time. The air intake are just protected by a mesh. This
mesh has to be vacuum cleaned occasionally when needed. No specific interval for this operation, but to be
performed when needed.
For more demanding surrounds both smoke and dust filters can be applied externally to the system to avoid
internal fouling.
General guidelines for cleaning projector filters (external)
Remove the filter from the projector then use a vacuum to remove excess dust from the filter. Do not wet or
soak the filter.
Cleaning of the projector filter should be done in a separate room to avoid dust contamination.
