1.6 INSTALLATIONS
1.6.1 INSTALLATION METHOD
This projector comes with the D-ILA system (reflecting type ac-
tive matrix liquid crystal system) that does not require conver-
gence adjustment.
Note the following when placed on a floor (refer to OPERATING
INSTRUCTIONS for actual operating method).
(1) Place the projector at the position needed for the required
image size, and observe that the projector is not tilted hor-
izontally.
*Refer to the WEB instruction manual for the projection dis-
tance.
Example: For 16:9 and the screen size is 60 inch, the tele-
end will be 1.75m; for 280 inch, the wide end will be
17.14m.
(2) Adjust the placement site and screen tilt so that the projec-
tion angle is perpendicular to the screen. Adjust the place-
ment site and screen position (height) so that the projection
lens center is at the lower edge of the screen.
(3) Project an image on the screen. (Connect video equipment
and power source, switch power on and select the input.)
(4) Slight adjustment will be made to the projection position
and projection angle of the image. When the projection po-
sition (height) shifts downward or when the projection an-
gle is not appropriate (lower end of the image widens) and
adjustment cannot be made to the installation location and
screen, adjust using the 4 movable feet at the bottom.
(5) By using "ZOOM" in LENS CONTROL, adjust for suitable
image size.
(6) By using "FOCUS" in LENS CONTROL, adjust to correct
image blur.
1.6.2 INSTALLATION SITE AND STATUS
The projector contains some fans for cooling. If the air inlets or
the vent holes of cooling fans are blocked, cooling efficiency may
deteriorate and temperature inside this unit will rise, and then it
can lead to abnormal operation and failure. Also observe there
is plenty of free space between the projector and adjacent walls,
ceiling and other equipment. Note that excess heat can cause
failure and damage to both the projector and nearby equipment.
Therefore, please make sure pay attention not to block the air in-
lets or the vent holes of cooling fans and allow sufficient space
around this unit.
1.6.3 DO NOT INSTALL AT THE FOLLOWING.
This unit is a precision device. Please refrain from installing or
using it at the following locations. Otherwise, it may cause fire or
malfunction.
• Dusty, wet and humid places
• Places subject to oily smoke or cigarette smoke
• On top of a carpet or bedding, or other soft surfaces
• Places exposed to direct sunlight
• Places with a high or low temperature
• Do not install this unit in a room that is oily or subject to ciga-
rette smoke. Even a small quantity of smoke or oiliness can
have a long-term impact on this unit.
* This unit produces a great amount of heat, and is designed to
take in cool air to cool its optical components. Using the unit at
the above locations may cause dirt to attach to the light path,
thereby resulting in dark images or dull colors.
* Dirt that sticks to the optical components cannot be removed.
1.6.4 MAINTAIN CLEARANCE FROM THE WALL, ETC.
As the unit discharges a large amount of heat, install it with ade-
quate clearance from the surroundings as shown below.
150 mm and above
300 mm

Front
Leave the front area of the unit unblocked.
If there is any obstructing object in front of the exhaust vent, hot
air will flow back to the unit and cause it to heat up. Hot air flowing
out of the unit may cause shadows on the screen (heat haze phe-
nomenon).
