5- Turn the projector upside down and hang on the ceiling with the assembly brackets.
6- Tilt the projector to centre the vertical picture and screw the two securing screws (H)
Note: Insert the special curved washers between the ceiling bracket and the securing screws. For a correct installation the concave surface of the washer should be towards the bracket. For safety purposes, use only the assembly kit supplied.

D = Distance between the line of the first hole of the assembly bracket and the screen.
Note: The screen size refers to the useful area (4/3 format).
4.3.5 Ceiling rear projection
Rear projection installation is done by hanging the projector on the ceiling and following the instructions given for front installation.
4.4Projection angle measurement
Use a goniometer to determine the projection angle. First of all, remove the projector’s top cover and then use the surface shown in the figure as reference for the goniometer.
The reference surface has an angle of 12 degrees compared to the projector’s base when it is perfectly level.
Note: the tilting angle between the base plane of the projector and the lenses’ axis should be 12°.

4.5 Spacers
The projector uses some spacers for the “Scheimpflug” correction of the lenses’ angle so as to achieve a perfect focusing uniformity over the entire screen surface.
The projector is factory set with spacers for a ceiling front installation with a 90” screen diagonal.
The projector is equipped with a complete set of optional spacers for screens ranging from 60” up to 300”.
The spacers are mounted between the lenses and the assembling block surface where they are fixed with 4 screws.
More than one spacer might be needed to achieve proper adjustment.
Lorrect use of the spacers, as shown in the tables, is of paramount importance for perfect focus uniformity.
