1. The case provides multiple attachment points for bolts,
cables, or threaded rod. Page 4 shows threaded rod installed.
The variable position-mounting bracket may be located
anywhere along the length of the case. It is recommended to
keep the brackets spaced evenly enough to distribute the
weight of the screen. One mounting bracket is required for
every 4' of case length.
2. Tighten bolts until trim flange is flush with ceiling.
NOTE: For proper operation, screen assembly must be level
after installation.
3. Remove 2 screws to open junction box. Install electrical
connections that apply to your unit. Make sure to review the
wiring diagram for proper hook up. Replace junction box
cover and secure with 2 screws.
NOTE: Please Note: Motor Operator Projection Screen
Models LADT, LADDT, LAD and LADD must be installed in
accordance with the requirements of the Local Building
Codes, the Canadian Electrical Code (CEC), CAN/CSA C22.1
and the National Electric Code (NEC), NFPA 70. An
appropriate disconnect device shall be provided as part of the
building installation.
If your case was ordered in advance of the screen and roller
assembly, your installation is now complete. Continue to
step 4 if your Large Advantage Electrol was ordered as a
complete unit.
4. Carefully remove paper and tape from roller assembly
CAUTION! DO NOT USE A KNIFE OR SHARP OBJECT
TO CUT TAPE; YOU WILL DAMAGE THE SCREEN.
PULL ORANGE STRING.
5. Test installation by running screen up and down a few times.
Be prepared to stop screen should any objects obstruct the
movement of the screen. To prevent damage to the motor,
the standard duty cycle is 1 minute on and 3 minutes off.

When using your video equipment, basic safety precautions should always be followed, including the following:
1. Read and understand all instructions before using.
2. Position the cord so that it will not be tripped over,
pulled, or contact hot surfaces.
3. If an extension cord is necessary, a cord with a current
rating at least equal to that of the appliance should be
used. Cords rated for less amperage than the appliance
may overheat.
4. To reduce the risk of electric shock, do not disassemble
this appliance. Contact an authorized service dealer
when repair work is required. Incorrect reassembly can
cause electric shock when the appliance is used
subsequently.
5. The use of an accessory attachment not recommended
by the manufacturer may cause a risk of fire, electric
shock, or injury to persons.

installation clearance.
4. Remove any protective foam from case.
5. If necessary. adjust hanger brackets with a 3/4" open wrench
or socket driver.

If your screen was shipped with the motor and roller already installed proceed to step 7.
1. Remove the access door. First, remove the 2 bolts from each
end with a 9/16" open wrench or socket driver. Next, use a
5/32" hex key to remove the two screws in the center of the
access door. This will allow the door to drop open on the hinges
(Figure 1).
2. Carefully unpack screen and roller assembly. Leave packing
paper on the roller.
3. Remove the square peg bracket from the motor end of the
roller assembly (Figure 2).
4. Remove the safety clip from the motor attachement bracket
located in the motor end of the screen housing.
5. Use a 1/2" open wrench or socket driver to loosen the four bolts
that secure pin end mounting bracket into housing. Lift pin end
of roller into position and slide the bracket into the roller pin.
Tighten all four bolts. Slide the pin end bracket towards the end
of the case (Figure 3).
6. Place the roller assembly into the case with the motor on the
left side. The limit switches should be facing down. Line up the
head of the motor with the motor attachment bracket.
7. Complete electrical hook-up by snapping motor 1/3 wire
connectors into case connectors (Figure 2).
8. Return to motor end and insert safety clip over casting bracket
to secure motor end.
9. Carefully remove tape strips securing picture surface around
roller. Slat should move freely. (Only if the roller assembly is pre
installed.)
CAUTION! DO NOT CUT TAPE ON FABRIC WITH A KNIFE
OR ANY SHARP TOOL. REMOVE BY HAND.
10. Test installation by running screen up and down a few times.
Be prepared to stop screen should any objects obstruct the
movement of the screen. To prevent damage to the motor, the
standard duty cycle is 1 minute on and 3 minutes off.
11. Re-install the access door. Procedure is the reverse of step 1
listed above.

Surface travel is stopped automatically in the fully opened and closed positions by limit switches that are properly adjusted at Da-Lite.
Should it be necessary to adjust for more or less drop of picture, proceed in the following manner:
NOTE: Use a screw driver or 5/32" Allen wrench to make adjustments.
1. Place operating switch in “down” position.
2. When the screen stops, turn the white “down” limit knob
one-quarter turn counterclockwise (Figure 4). Test by raising
picture surface approximately two feet, then lower again.
Repeat until desired picture surface position is attained.
CAUTION: DO NOT ADJUST FOR MORE DROP THAN
WHAT WAS ORDERED. AT LEAST 1-1/2 WRAPS OF
FABRIC MUST REMAIN ON THE ROLLER. THIS SCREEN
COMES STANDARD WITH 0" OR 2" BLACK AT THE TOP.
SEE THE SPECIFICATION DATA SHEET FOR DETAILS.
1. Raise picture surface approximately two feet above
desired level.
2. Place operating switch in “off” position.
3. Turn the white “down” limit switch one-quarter turn clockwise
(Figure 4). Test by raising picture surface approximately two
feet, then lower again. Repeat until desired picture surface
position is attained.
