Installing the Projector	17

Installation Requirements

The projector supports the following four different projection methods. Install the projector according to the conditions of the installation location.

•Project images from in front of the screen. (Front projection)

•Project images from behind a translucent screen. (Rear projec tion)

•Suspend the projector from the ceiling and project images from in front of a screen. (Front/Ceil ing projection)

•Suspend the projector from the ceiling and project images from behind a translucent screen.

(Rear/Ceiling projection)

Warning

•A special method of installation is required when suspending the projector from a ceiling (ceiling mount). If installation work is not carried out correctly, the projector could fall down. This may result in injury or accidents.

Contact your dealer or the nearest address provided in the Epson Projector Contact List if you want to use this installation method. s "Epson Projector Contact List" p.67

•If you use adhesives on the Ceiling mount fixing points to prevent the screws from loosening, or if you use things such as lubricants or oils on the projector, the projector case may crack causing it to fall from its ceiling mount. This could cause serious injury to anyone under the ceiling mount and could damage the projector.

When installing or adjusting the ceiling mount, do not use adhesives to prevent the screws from loosening and do not use oils or lubricants and so on.

•Do not cover the projector's air intake vent or air exhaust vent. If either of the vents are covered, the internal temperature could rise and cause a fire.

Attention

Do not use the projector on its side. This may cause malfunctions to occur.

Installing the Projector	18

a• An optional ceiling mount is required when suspending the projector from a ceiling.

•The default Projection setting is Front. You can change from Front to Rear from the Configuration menu.

Press [Menu] button > Extended > Projection

Horizontal: Can be tilted within the range of expansion and contraction for the rear feet. s p.22

Make sure there is a gap of at least 50 cm between the wall and the air exhaust vent and the air intake vent.

Air exhaust vent

Air intake vent

When setting up multiple projectors, make sure there is a gap of at least 50 cm between the projectors. Also, make sure the heat coming out of the air exhaust is not taken in through the air inlet.

Installing the Projector

Adjusting the Position of the Projected Image

(Lens Shift)

The lens can be shifted to adjust the position of the projected image, for example, when the projector cannot be installed directly in front of the screen.

a Release the lens shift dial lock.

b Turn the vertical and horizontal lens shift dials on the projector to adjust the position of the projected image.

19

Attention

When adjusting the image height with the vertical lens shift dial, adjust by moving the image from the bottom to the top. If it is adjusted from the top to the bottom, the image position may move down slightly after adjusting.

a• We recommend setting the focus, zoom, and lens shift at least 30 minutes after you start the projection, because images are not stable right after turning on the projector.

•The image will be clearest when both the vertical and horizontal lens shift are set in the center.

Installing the Projector

The ranges within which the image can be moved are shown below.

You do not need to set the Screen Type when the default value is the same as the aspect ratio for the screen being used.

Adjusting the position of the image on the projected screen

You can adjust the position of the image if there are margins between the edge of the image and the projected screen frame due to the Screen Type setting.
