SAFETY WARNINGS AND GUIDELINES
Please read this manual thoroughly, paying extra attention to these safety warnings and
guidelines. Keep this manual in a safe place for future reference.
Installation and Operation
This product should only be installed by a qualified structural contractor. Failure to
follow proper structural code in regard to hanging equipment could result in serious
injury or death.
The ceiling structure to which this projector screen will be attached must have a
minimum load bearing capacity four times the total weight of the screen.
Frequently inspect the installation for imbalance and signs of wear or damage. Do
not use if repair or adjustment is needed.
Prior to operation, ensure that the sticker on the casing and underbar is removed.
General
This device is intended for indoor use only.
Do not expose this device to water or moisture of any kind. If water does get in or
on the device, unplug it from its power source and allow it to fully dry before
reapplying power.
Do not touch the device, the power cord, or any other connected cables with wet
hands.
Do not expose this device to excessively high temperatures. Do not place it in, on,
or near heat sources, such as a fireplace, stove, radiator, etc. Do not leave it in direct
sunlight.
All wires and cables installed inside the ceiling must be rated for in-wall/in-ceiling
use by the UL or a similar certification agency. An in-wall rating is sufficient for
residential installations, while a riser or plenum rating is required for commercial
installations. Please refer to your local building regulatory agency for guidance.

4
Do not place or install this device in an area where it can be exposed to excessive
amounts of dust, humidity, oil, smoke, or combustible vapors.
When it is extended, take care not to shake the screen or attempt to manually lift it
up.
This device has no user serviceable parts. Do not attempt to repair or disassemble
this device.
The motor requires no periodic lubrication.
Power
Remove power from the AC circuit prior to wiring the motor to the circuit by
turning off the circuit breaker or the main power switch to the building.
This device requires a grounded/earthed power connection for safe operation.
If using a fixed electrical connection (directly wired to a power source), install a
quick disconnect device inline where it can be readily accessible. If using a standard
AC power plug, ensure that the power outlet is readily accessible so that power can
be removed in the event of an emergency.
All wires and cables installed inside the ceiling must be rated for in-wall/in-ceiling
use by the UL or a similar certification agency. An in-wall rating is sufficient for
residential installations, while a riser or plenum rating is required for commercial
installations. Please refer to your local building regulatory agency for guidance.
Unplug this device from the power source when not in use.
Take care to prevent damage to the power cord. Do not allow it to become
crimped, pinched, walked on, or become tangled with other cords. Ensure that the
power cord does not present a tripping hazard.
Never unplug the unit by pulling on the power cord. Always grasp the connector
head or adapter body.
Ensure that power is turned off and disconnected before making any electrical
connections.

Remove the batteries from the controller if it will go unused for a lengthy period of
time.

PRODUCT OVERVIEW
INSTALLATION
1. Measure, mark, and cut the ceiling cut-out. The cut-out dimensions depend upon
the size/model of screen you have.
Model A: 7951, 30453 (≥150")
Cut-out Length = Screen Length - 26mm
Cut-out Width = 150mm
Height ≥ 160mm

7
Model B: 7337, 7338, 30451, 30452 (<150")
Cut-out Length = Screen Length - 26mm
Cut-out Width = 115mm
Height ≥ 120mm
2. Carefully measure the distance from the closest wall to the center of the screen.
3. Verify the length of the screen size by measuring the distance between the center
of the two screw holes on the upper left and upper right brackets.
4. Use these measurements to mark your drill location in the roof structure.
5. Measure the distance between the roof structure and the ceiling. Cut the threaded
rods to the measured length, minus 16mm (0.63"). If the distance is greater than
500mm, you will need to get longer 1/4" threaded rods and new concrete anchors.
6. Mount the anchors and threaded rods in the desired location.

8
7. Carefully lift the screen assembly to insert the threaded rod through the upper
screw hole. Attach a safety nut 3-4" up the threaded rod. Repeat for the other side.
8. Adjust the safety nut so the threaded rod goes through the lower screw hole.
Loosely attach the lock nut.
9. Use a carpenter's level to ensure the screen is level and at the proper height so it is
flush with the ceiling. Adjust the safety nuts to level and raise or lower the screen,
as needed.
10. When the screen is flush and level, secure it in place using the lock nut on the lower
bracket.
11. Install the end caps.
