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.
6. Failure to provide adequate structural strength for this
component can result in serious personal injury or damage
to equipment! It is the installer’s responsibility to make sure
the structure to which this component is attached can
support the weight of all equipment. Reinforce the structure
as required before installing the component.
7. Use this projection screen only for its intended use as
described in these instructions. Do not use attachments not
recommended by the manufacturer.

1. The case provides multiple attachment points for bolts,
cables, or threaded rod. Page 7 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.
The case has a self-trimming lange around the bottom.
Ceiling tiles or drywall may be placed on top of this lange to
provide a inished appearance.
2. After securing the case in the ceiling check that the case is
level and plumb.
3. Use supplied 1/8" hex key and a 1/4" wrench to remove silver
shipping brackets attached to slat and screen case.
4. Install electrical connections that apply to your unit. Refer to
the following diagrams for proper installation. The diagrams
on page 6 are for standard controls; the diagrams on page 7
are for SCB100 controls and page 8 for SCB200 controls. The
terminal block for the wall switch connections is located
under the metal housing surrounding the junction box.
Remove two screws for access.
NOTE: Use provided knockouts for all electrical connections.

Screen And Roller Assembly Installation
If your screen was shipped with the motor and roller already installed proceed to step 6.
1. Remove the screw from each end of the access door (front
door) and open the door. See igure 1.
2. Carefully unpack screen and roller assembly. Leave packing
paper on the roller.
3. Place the roller assembly into the case with the motor on the
left side. The limit switches should be facing down. Line up
the square pin on the motor with the square hole in the
bracket.
4. Lift the pin end (right end) of the roller into position and slide
the bracket onto the roller pin. Tighten two nuts to secure the
bracket.
5. Complete electrical hook-up by snapping motor wire
connector into case connector.
6. Remove shipping brackets by removing the hex head screws
from aluminum slat and case. Slat should move freely. See
igure 2. (Only if the roller assembly is preinstalled.)
7. Test installation by operating the screen several times. Be
prepared to stop the screen. Standard Duty Cycle: 1 MIN. ON/3
MIN. OFF. The fabric door (rear door) will not close until the
wall switch is placed in the up position and when the screen
motor stops at its limit switch in the up direction.
CAUTION: Excessive continuous operation may cause the
motor to overheat. If this happens the motor will shut of
until it cools to a normal operating temperature.
ATTENTION! Le fonctionnement continu et excessif peut
provoquer une surchaufe.Si cela se produit, les moteurs
s'arrêteront jusqu'à qu'ils se soient refroidis à la
température normale de fonctionnement.
8. Run the screen down enough to open the fabric door. Close
the access door and reinstall the screws to secure the door.

CAUTION: Contact Da-Lite at 8006223737 or 5742678101 if screen or door motor needs adjustment.
ATTENTION: Contactez Da-Lite au 8006223737 ou au 5742678101 au cas le moteur de l'écran a besoin d'être ajusté.
Screen Adjustment
NOTE: Use a screw driver or 5/32" Allen wrench to make adjustments.
More Screen Drop
1. Place operating switch in “down” position.
2. When the screen stops, turn the white “down” limit knob (Fig.
2) one-quarter turn counterclockwise. 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 11/2 wraps of fabric must remain on
the roller. This screen comes standard with 12" black
at the top.
ATTENTION! N'efectuez pas de réglage pour obtenir un
déroulement supérieur à celui commandé. Au moins 1 à 1/2
tour de toile doit être maintenu sur le cylindre. Cet écran est
doté de série d'une bande noire supérieure de 0 cm (0 po) ou
5 cm (2 po). Consultez la iche technique pour plus de
renseignements.
Less Screen Drop
1. Raise picture surface approximately two feet above
desired level.
2. Place operating switch in “of”position.
3. Turn the white “down” limit switch (Fig. 2) one-quarter turn
clockwise. Test by raising picture surface approximately two
feet, then lower again. Repeat until desired picture surface
position is attained.
CAUTION: Adjusting the down limit switch for less drop by
more than 6" can cause the screen surface to lose proper
tensioning.
