Important Safety Instructions
Pre-Installation
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.

Case Installation
1. The case provides multiple attachment points for bolts,
cables, or threaded rod. Page 8 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. Install electrical connections that apply to your unit. Refer to
the following diagrams for proper installation. The diagrams
on page 5 are for standard controls; the diagrams on page 6
are for SCB100 controls and page 7 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.

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.
CAUTION! Do not cut tape on fabric with a knife or any
sharp tool. Remove by hand.
Screen Motor
6. Carefully remove tape strips securing picture surface around
roller. Slat should move freely (Fig. 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.
NOTE: 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.
8. Run the screen down enough to open the fabric door. Close
the access door and reinstall the screws to secure the door.
