1. Install screen by raising unit into position between joists at
one end only. Install one lag screw in each mounting bracket.

review your electrical installation checklist and wiring diagrams
(included) for either 120 volt switch, 220/240 volt switch or DRC
low voltage control.
NOTE: Must be installed in accordance with the requirements of
the Local Building Codes, the Canadian Electrical Code (CEC), CAN/
CSA C22.1 and the National Electric Code (NEC), NFPA 70.
CAUTION! Do not cut tape on fabric with knife or any sharp

and down several times. Be prepared to stop screen. Standard

down past the bottom of the viewing surface, then “step back”
against the viewing surface to eliminate shadowing by rolling up
the back side of the roller. Do not adjust the limits to change this
