INVERT THE PROJECTOR IMAGE
Please refer to the owners manual for your LCD Projector for detailed instructions of how to electrically
invert the projected image to accommodate its use in the ceiling mounted mode.
LOCATION OF THE CEILING BRACKET
Please refer to the owner’s manual for your SHARP LCD PROJECTOR for information which will help
you to determine the best location for the placement of the ceiling mounting bracket assembly.
INSTALLATION OF THE CEILING BRACKET
After you have determined the appropriate location for the ceiling bracket, you must locate the exact
location of the ceiling beams. Most standard residential construction uses 16 inches between centers
for overhead beams. You can mount the ceiling bracket by straddling two beams, or you can install the
bracket in line with a single beam.
CAUTION: THE BRACKET MOUNTING SCREWS MUST GO DIRECTLY INTO THE BEAMS.
SHEETROCK, LATH AND PLASTER, WILL NOT PROVIDE A SUFFICIENTLY SECURE
SUPPORT.
STEP 1. INSTALLATION OF THE METAL CEILING BRACKET
After the location for the ceiling bracket has been determined, (see LCD PROJECTOR
Owner’s Manual), make sure to locate beams in the ceiling.

CEILING BRACKET AN-CM270
1.1 a.
b.
Select straddle beam or single beam installation.
Use the ceiling bracket as a template to mark the location where the pilot holes
should be drilled.
c.
Drill the pilot holes for the support screws using a 1/8” drill bit into the center of
the beam. (See Figs. 2 and 3).
1.2 Screw the ceiling plate to the beams. Use at least 6 screws and metal washers
supplied with the unit. These screws should be tightened firmly to insure a
vibration-free support. (See Figs. 2 and 3).
Two sizes of hex head lag bolts are provided. Use shorter screws for sheet rock
surfaces and use the longer screws if the ceiling surface is constructed of a wood
lath and plaster.
CAUTION: THE BRACKET MOUNTING SCREWS MUST GO DIRECTLY INTO
THE BEAMS. SHEETROCK OR LATH AND PLASTER WILL NOT PROVIDE A
SUFFICIENTLY SECURE SUPPORT.

2.1
2.2
The Access Hole (See Fig. 4) in the ceiling attachment plate is large enough to accommodate the
molded connectors commonly used the with projector.
Audio, Video and other low voltage connections may be passed through the access hole in the
ceiling plate and may also be passed through the plastic trim cover. There is a label (See Fig. 4) on
the inside of the plastic trim cover, adjacent to the center mounting bushing.
Select the contour appropriate for your application and cut out the opening along the line indicated
on the label. Use a very sharp cutting tool.
2.3
2.4
Thread the cable through the plastic trim cover. Place the plastic trim cover in place over the
ceiling plate and press the velcro tabs together.

STEP 3 DETACH THE POSITIONING ASSEMBLY FROM THE PROJECTOR ATTACHMENT
PLATE.
NOTE: PLEASE LOOK OVER THE EXACT MANNER IN WHICH THE
FIGURE 5
POSITIONING ASSEMBLY AND THE ATTACHMENT PLATE GO
TOGETHER SO THAT YOU WILL BE ABLE TO REASSEMBLE THEM
WHEN YOU HANG THE PROJECTOR.
3.1 Using 9/16” box wrench, remove the nut from the lower knuckle
(vertical position) and slide the center and upper knuckle assembly apart
from the bottom knuckle which is part of the
attachment plate. (See Fig. 5)
SPECIAL NOTE TO INSTALLERS: In some instances the relationship of
the location of the projection screen to the exact position of the ceiling
mounting bracket makes it desirable to have the centerline of the lens at
the center of the mounting bracket. If you find it necessary to have the
lens at the centerline of the mount, remove the lower element of the
positioning knuckle from its original position and re-mount it in the D
shaped hole in the mounting plate located in the area over the lens. This
will align the centerline of the lens with the center of the mounting
bracket. The positioning knuckle assembly can easily compensate for the
slight loss of static balance of the mounted projector.
STEP 4 INSTALLATION OF THE PROJECTOR ATTACHMENT PLATE
4.1 Place the attachment plate over the bottom of the projector (See Fig. 6)
and align the holes of the plate with the threaded fittings on the projector case.
4.2 Install the three M4 x 12mm long screws provided. Fasten these securely but
DO NOT overtighten. (See Fig. 7)
4.3 Install the longer, M4 x 30 mm flat head screw into the indicated hole. (It goes
into the recessed fitting in the plastic housing).

4.3 Fold the attachment plate down on its hinge. See Fig. 8
4.4 Install the M4 knurled thumb screw by hand. See Fig. 8. DO NOT USE TOOLS TO
TIGHTEN THIS SCREW.

IF YOU INTEND TO RUN AUDIO OR VIDEO CABLES THROUGH THE CEILING PLATE
PROCEED WITH STEP 5.1 AND 5.2, OTHERWISE PROCEED TO STEP 5.3:
5.1 Cut opening in the ceiling plate trim cover as indicated on the label inside cover near
the center bushing.
5.2 Thread cables through the plastic trim cover.
DO NOT RUN THE AC POWER CORD INSIDE THE PLASTIC TRIM COVER.
ALL WIRING MUST COMPLY WITH THE NEC AND ALL LOCAL BUILDING,
ELECTRIC, AND SAFETY CODES.

5.3 Place the plastic trim cover in position over the ceiling plate and press the Velcro
tabs together.
5.4 After completing step #5.3, screw the longer shaft with the locking nut and washer
into the center threaded bushing on the ceiling plate as far as it will go. (See Fig. 9)
5.5 Tighten the locking nut against the ceiling plate using a 3/4” open end wrench or an
adjustable crescent wrench.
5.6 Tighten the locking nut on the upper knuckle using a 9/16” box wrench.
DO NOT RUN THE AC POWER CORD INSIDE THE PLASTIC TRIM COVER.
ALL WIRING MUST COMPLY WITH THE NEC AND ALL LOCAL BUILDING,
ELECTRIC, AND SAFETY CODES.
STEP 6 HANGING THE PROJECTOR FROM POSITIONING ASSEMBLY
6.1 Raise the projector with the mounting plate attached and slide the fitting (See Fig. 10)
over the support stud on the hanging position.
6.2 Replace the locking nut (removed in step 3.1). Using the 9/16” box wrench run the nut
up but do not tighten all the way.
FIGURE 10
STEP 7 AIM THE PROJECTOR
7.1 After the projector has been property wired, turn it on and loosen the positioning
assembly adjustment nuts just enough so that you can move the projector fairly easily.
(See Fig. 11) DO NOT COMPLETELY LOOSEN THE NUTS.
7.2 Set the Horizontal Centering by loosening the ceiling locking nut, move the projector to
center the image and tighten the nut. (Use 3/4” open end wrench).
7.3 Set the vertical centering and tighten the lower positioning adjustment nut.
(See Fig. 11)
7.4 Set the Horizontal tilt and tighten the upper positioning adjustment nut. (See Fig. 11)

STEP 8 INSTALL THE PLASTIC TRIM COLLAR
8.1 The plastic trim collar may be used as a cosmetic concealment of the positioning adjustment knuckle
assembly and the audio and video signal cables.
8.2 The slit side of the collar enables the installer to spread the collar enough to place it over the adjustment
knuckle. It will curve back by its own spring action to wrap around itself enough to close the gap.
(See Fig. 12)
8.3 If the projector is hung at a sharp angle, you may trim the collar for a better fit. (See Fig. 13)

PROCEDURE FOR SERVICING LAMP HOUSING OR AIR FILTER:
A. Remove the knurled thumb screw. See Fig. 14. The projector will swing down on the
hinge of the mounting bracket. The bottom of the projector will now be in a position to
permit servicing the lamp assembly.
B. Proceed to service the air filter or the lamp assembly. Follow the appropriate
instructions in your projector owner’s manual.
