Additional Tips
Keep the new lamp in the packaging until you are ready to install it to avoid possible damage to the lamp.
One of the most common mistakes made during installation is accidently touching the glass on the new lamp. Do not touch the new lamp at any point with your bare hands, it is even recommended to wear gloves for this process. Oils from your skin will cause "hot spotting" on the lamp which increases the stress on certain areas of the lamp due to overheating which will result in significantly reduced lamp life.
If unfamiliar with the wiring, make sure to mark each cable on the back of the projector before removing the cables.
