13.1 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
fi
ngerprints 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
fi
rst indication of a dirty cloth.

W
ARNING
:
Always disconnect the projector from the mains power net before attempting to clean the projec-
tor cabinet.
General guidelines for cleaning the projector cabinet (exterior only)

detergent solution.
13.3 Filters
General info regarding Air intake and
fi
lters.
The product is shipped default without any
fi
lters and by avoiding
fi
lters, the ventilation system operates for longer periods between
maintenance, since no clogging of
fi
lters 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 speci
fi
c
interval for this operation, but to be performed when needed.
For more demanding surrounds both smoke and dust
fi
lters can be applied externally to the system to avoid internal fouling.
General guidelines for cleaning projector
fi
lters (external)
Remove the
fi
lter from the projector then use a vacuum to remove excess dust from the
fi
lter. Do not wet or soak the
fi
lter.
Cleaning of the projector
fi
lter should be done in a separate room to avoid dust contamination.
