Important Safety Instructions
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 ire, electric shock, or injury to
persons.

Remove the black tape and rubber bands from the slat bar after the case has been installed.
The Large Cosmopolitan Electrol comes with brackets to allow for wall mount or ceiling mount installations. Procedures for each
method are as follows:
Wall Mount
1. The wall mount bracket should be fastened to wall studs or
some reinforcement within the wall. Concrete or brick walls
require special fasteners and anchors.
2. The wall bracket has holes spaced at 16" and 24" to align with
most wall studs.
3. The bracket must be level and plumb.
4. Keep in mind you will need at least 23/4" between the ceiling
and the top of the wall mount bracket to be able to position
the case on the bracket.
5. Mount the screen case on the wall bracket as shown in
igure 2. Be sure the case is fully seated on the bracket.
Tighten the stop screws against the wall bracket.
Ceiling Mount
1. Be sure the ceiling has adequate reinforcement to attach the
screen brackets.
2. Attach the ceiling brackets to the wall mount bracket using
the supplied 5/16" x 3/4" bolts, washers and nuts.
3. Position the ceiling bracket assembly on the ceiling and
attach with 5/16" bolts (not supplied). The bolts should be
long enough to pass through the drywall or ceiling tile and
penetrate at least 11/2" into the reinforcement in the ceiling.
4. Mount the screen on the wall bracket as shown in igure 3. Be
sure the case is fully seated on the bracket. Tighten the stop
screws against the wall bracket.

Installation For Screens Without A Built-In Low Voltage Control
Internal wiring has been completed at the factory. Installer must route power to the wall switch and to the junction box located on the
left end of the screen case.
See wiring diagram below for wire connections.
NOTE: This screen can only be controlled by a single 120VAC or 240VAC wall switch. To use multiple switches, an optional low voltage
control must be used.
240 VOLT WIRING DIAGRAM FOR STANDARD WALL SWITCH:
Da-Lite ofers two styles of 240 volt wall switches for standard operation.
Please see wiring diagram in wall switch boxes included with screen.
This Switch Can Not
be used with LVC.

Screen Adjustment For Screens Without A Built-In Low Voltage Control
Screen travel is stopped automatically in the down and up positions by the limit switches that are preset at the factory.
No further adjustment is necessary.
If you need to make minor stop position adjustments see the appropriate step below.
SETTING THE DOWN LIMIT POSITION
NOTE: One turn of the limit screw equals approximately 2" of
screen travel.
To Reduce Screen Drop: Turn the down limit switch screw clockwise
to decrease the amount of screen drop. Run the screen down to test
the stop position. If the screen drops too far, raise the screen about
one foot and adjust the limit switch again. Repeat until the
desired position is set.
To Increase Screen Drop: Turn the down limit switch screw
counterclockwise to increase the amount of screen drop. Run the
screen down to test the stop position. If the screen does not drop
enough, raise the screen about one foot and adjust the limit switch
again. Repeat until the desired position is set. Do not adjust for more
drop than what was ordered. At least 11/2 wraps of fabric must remain
on the roller.
SETTING THE UP LIMIT POSITION
CAUTION: Do not allow the slat bar to wrap over the top
of the roller when the screen is rolling into the case.
The screen could be damaged.
ATTENTION: Évitez que la barre inférieure ne s'enroule au
dessus du cylindre lorsque l'écran est enroulé dans le caisson.
L'écran pourrait être endommagé.
Screen Travels Into Case Too Far: Turn the up limit switch screw
clockwise to decrease the amount of travel. Run the screen up to test
the stop position. If the screen does not stop properly, lower the
screen about one foot and turn the limit switch again. Repeat until the
desired position is set.
Screen Does Not Travel Far Enough Into Case: Turn the up limit
switch screw counterclockwise to increase the amount of up travel.
Run the screen up to test the stop position. If more travel is desired,
lower the screen about one foot and adjust the limit switch again.
Repeat until the desired position is set.

until the LED on back of switch turns solid green. This will put the
motor in limit set mode. Turn the wall switch over and use the up
button on front of switch. Press and hold until the desired travel
position is reached. If you travel to far up you can press the down
to move the screen downward. If you press and let go of either up
or down button the motor will do a small jog in that direction for
iner adjustment of screen. Once desired position is reached turn
switch over press and hold up tactile button until the LED on back
of switch blinks green twice. The up limit is now set.
5. To test limit switch setting, press and release the up or down
button on the wall switch to operate the screen.
6. Replace switch and cover plate on the wall.
NOTE: If the screen is in limit set mode and no buttons are
pushed for 20 seconds, the LED on the back of the wall switch
will turn of, the motor will return to run mode and no changes will
be saved. If this occurs, return to step 3 for down limit adjustment
or step 4 for up limit adjustment.
IMPORTANT NOTE: The wall switch is REQUIRED to make any
limit switch adjustments, EVEN if a third party control system is
used. Therefore, it is advised to wire the switch or provide a
3-conductor connection that is accessible.
