How to install Da-Lite Professional Electrol 339" Electric Projection Screen

• Plan the installation by selecting the mounting method that best suits your space—ceiling recessed, wall mounted, or ceiling suspended—consider sightlines, projector placement, and electrical access during the design phase.
• Prepare the mounting surface and structural supports, verifying load capacity and ensuring the ceiling or wall can safely accommodate the screen housing and any required hardware. Verify any local codes or facility standards before proceeding.
• Attach the adjustable mounting brackets to the building structure, ensuring they are level and spaced according to the screen’s specifications. Use a laser or spirit level to confirm precise alignment to guarantee a perfectly plumb screen surface once installed.
• Mount the wooden housing securely to the brackets, route any necessary wiring for the motorized mechanism, and verify there is unobstructed space for the drop and retraction of the screen without interference.
• Unroll and test the screen surface, then calibrate the drop height and bracket alignment as needed. Run multiple retraction cycles to confirm smooth operation, listening for unusual sounds or binding, and make any final adjustments to ensure consistent performance and longevity.
