Maintaining the Projector
Ä
CAUTION: Cleaning requires special consideration:
■
Do not spray any type of fluid or cleaner directly on the lens surface. Cleaners
might damage the lens.
■
Do not use fabric softener when washing a cleaning cloth or softener sheets
when drying the cloth. Chemicals on the cloth might damage the surface of the
lens.
■
Do not store a cleaning cloth in contact with the lens for a long time because
doing so contaminates the lens with dye from the cloth. The cloth can be
contaminated if left in the open air.
To replace the lamp module
Å
WARNING: Replacing the lamp module requires special consideration:
■
When the lamp nears its end of life, it might break. To reduce the risk of injury,
be careful when removing the lamp module as broken glass might be present.
For a ceiling installation, wear goggles and gloves when removing the lamp
module. If the lamp is broken, contact HP about repairs that might be required.
■
Because the lamp assembly operates at a very high temperature, wait 30
minutes before removing the lamp module.
1. Turn off the projector and allow it to cool for 30 minutes.
2. Slide the latch upward on the front of the projector.
3. Slide the lamp housing off the projector.
4. Slide the new lamp housing onto the projector.
5. Push down the latch.
