For critical situations (fixed installs that use the lens at one of its extreme zoom positions) this should be
taken into account.

It’s recommended to place the Lens caps of the original Lens packaging, back on both sides of the removed
Lens to protect the optics of the Lens.
It’s recommended to place the foam rubber of the original projector packaging, back in the Lens opening to
prevent intrusion of dust. Note that this foam rubber is packed in a plastic bag to prevent the dust, emitted by
the foam, from entering the projector.

2.3
Cleaning the lens
To minimize the possibility of damage to optical coatings, or scratches to lens surfaces, we have developed
recommendations for cleaning. FIRST, we recommend you try to remove any material from the lens by blowing
it off with clean, dry deionized air. DO NOT use any liquid to clean the lenses.
Necessary tools
Toraysee TM cloth (delivered together with the lens kit). Order number : R379058.
How to clean the lens ?
1. Always wipe lenses with a CLEAN Toraysee TM cloth.
2. Wipe lenses in a one single direction.
Warning: Do not wipe back and forwards across the lens surface as this tends to grind dirt into the coating.
3. Do not leave the cleaning cloth in either an open room or lab coat pocket, as doing so can contaminate the cloth.
4. If smears occur when cleaning lenses, replace the cloth. Smears are the first indication of a dirty cloth.
CAUTION: Do not use fabric softener when washing the cleaning cloth or softener sheets when drying the
cloth.
Do not use liquid cleaners on the cloth as doing so will contaminate the cloth.
Other lenses can also be cleaned safely with this Toraysee TM cloth.
