PRE-INSTALLATION

1. Carefully unpack screen.

INSTALLATION
1. Install screen by raising unit into position between joists at one end only. Install one lag screw in mounting bracket.
2. Level unit lengthwise with a carpenter's level and plum level. Secure end.
3. Remove junction box cover plate.
4. Install electrical hook up that applies to your unit. Make sure to review your electrical checklist and wiring diagrams
(included) for either 120 volt switch, 220/240 volt switch, or DRC low voltage control.
NOTE: Screen has been internally wired at Da-Lite. Wiring designated "external" is completed by installer
conforming to local and national codes.
CAUTION! DO NOT CUT TAPE ON FABRIC WITH KNIFE OR ANY SHARP TOOL. REMOVE BY HAND.
5. Carefully remove tape strips securing picture surface around roller. Slat should move freely (Fig. 1).

7. Run the picture surface upward. When the picture surface is fully up a limit switch (in the motor) is tripped and the
motor shuts off.
8. Check for satisfactory condition by operating screen a few times. CAUTION! Excessive continuous operation
may cause overheating.

raising picture surface approximately two feet, then lower again. Repeat until desired picture surface position is
attained.
