Maintaining the Projector
To clean the projector lens
■To minimize the risk of damaging or scratching the lens surface, blow dust 
particles off the lens with clean, dry, deionized air.
If this method does not work, use the following method:
■Wipe the lens in a single direction with a clean, dry cloth. Do not wipe back and 
forth across the lens.
If the cloth is dirty or smears the lens, wash the cloth. If the cloth is still dirty after 
washing it or the fabric is damaged, replace it.
ÄCAUTION: 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
ÅWAR N I N G: Replacing the lamp module requires special consideration:
■To reduce the risk of injury, be careful when removing the lamp module as 
broken glass might be present in the unlikely event the lamp is broken. If the 
lamp is broken, contact HP about repairs that might be required.
■The lamp contains a small amount of mercury. If the lamp breaks, adequately 
ventilate the area where the breakage occurred. Disposal of this lamp might be 
regulated due to environmental considerations. For disposal or recycling 
information, contact your local authorities or the Electronic Industries Alliance 
(http://www.eiae.org).
■Because the lamp assembly operates at a very high temperature, wait 
30 minutes before removing the lamp module.

Installing Permanently
To install on the ceiling
ÅWAR N I N G: To minimize the risk of injury from improperly installed equipment, it 
is recommended that a professional installer performs the ceiling installation.
✎The actual projector and mounting plate differ from those shown below, but the steps 
are the same.
1. Attach the mounting plate to the bottom of the projector. The pointed part of the 
hole in the bracket faces the back of the projector. See the instructions that came 
with the ceiling mount.
2. Attach the ceiling-mount bracket to the ceiling, and firmly secure with three or 
four screws capable of holding 9 kg (20 lb). The ceiling-mount bracket must be 
located 1.2 to 12 m (4 to 40 ft) in front of the screen. See the table in “Setting Up 
the Projector” on page 15.
