2.6 Lamp & Ballaster drawing
1.The lamp becomes high temperature after turning off the projector with the power
button. If you touch the lamp, you may scald your finger. When you replace the lamp,
wait for at least 45 minutes for the lamp to cool down.
2.Do not touch the lamp glass at any time.The lamp may explode due to improper
handling, including the touching of the lamp glass.
3. Lamp lifetime may differ from lamp to lamp and according to the environment of use.
There is no guarantee of the same lifetime for each lamp. Some lamps may fail or
terminate their lifetime in a shorter period of time than other similar lamps.
4.Alamp may explode as a result of vibration, shock or degradation as a result of hours
of use as its lifetime draws to an end. Risk of explosion may differ according to the
environment or conditions in which the projector and lamp are being used.
5. Wear protective gloves and eyeglasses when fixing or detaching the lamp.
6. Faster on-off-cycles will damage the lamp and reduce lamp life. Wait at least for 5
minutes to turn off the projector after powering on.
7.Do not operate the lamp in proximity to paper, cloth, or other combustible material nor
cover it with such materials. Otherwise it could cause a fire.
2.7 Instructions for use

5Chapter 1
8.Do not operate the lamp in an atmosphere containing an inflammable substance, such
as thinner. Otherwise it could cause a fire or explosion.
9. Thoroughly ventilate the area or the room when operating the lamp in an oxygen
atmosphere (in the air). If ozone is inhaled, it could cause headaches, nausea,
dizziness, etc.
10. The inorganic mercury is involved in the lamp. If the lamp bursts, the mercury inside the
lamp will go out of the projector. Leave the area immediately if the lamp shatters while
being operated and ventilate the area for at least 30 minutes in order to avoid the
inhalation of mercury fumes. Otherwise it could be harmful to user’s health.
11.Dispose of the used lamp according to local regulations.
12. Ensure that screws are tightened properly. Screws not tightened fully may result in
injury or accidents.
13. Since the lamp is made of glass, do not drop the unit and do not scratch the glass.

proper disposal.
Caution : This lamp emits ultra violet (UV) radiation and operates at high
pressure.
This lamp may only be used in enclosed fixtures that comply with
UL1572.
Due to the high luminous efficacy, the UV radiation which the lamp
emits and the high pressure within the lamp, P-VIPâ lamps may only be
operated within enclosed, purpose-built housings.
