IMPORTANT SAFETY INSTRUCTIONS
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 rat-
ing at least equal to that of the appliance should be used.
Cords rated for less amperage than the appliance may over-
heat.
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 fire, electric shock, or
injury to persons.

PRE-INSTALLATION
1. Carefully unpack screen.
2. Make sure to recheck measurements of screen location before installation.
3. Remove center support brackets (on 8' and wider screens only), reverse brackets and reinstall flush with the top of the
box.
INSTALLATION
1. Install screen by raising unit into position between joists at one end only. Install one lag screw in each mounting
bracket.
2. Level unit lengthwise with a carpenter’s level and plumb level. Secure opposite end.
CAUTION! Do not seal in until screen has been secured in position and properly tested for satisfactory operation.
3. Detach access panel by removing screws, see figure 1.
4. Remove junction box cover plate.
5. Install electrical hook up that applies to your unit. Make sure to review your electrical installation checklist and wir-
ing 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 TOOL. PULL ORANGE STRING.
6. Carefully remove wood boards securing mask surface to case.
7. Carefully remove tape strips securing picture surface around roller. Slats should move freely (Fig. 2).
8. Test installation by carefully running picture and mask surfaces up and down several times. Be prepared to stop
screen. Standard Duty Cycle: 1 MIN. ON / 3 MIN. OFF.
9. Run the picture surface upward. When the picture surface is fully up the limit switch (in the motor) is tripped and
the motor shuts off.
10. Test the mask surface the same as testing the picture surface. The mask will start down off the front of the roller,
travel completely 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 feature.
11. Check for satisfactory condition by operating screen a few times. Reinstall access panel.

NOTE: Use a screw driver or allen wrench to make adjustments.
MORE SCREEN DROP
1. Remove access panel (Fig. 1).
2. Place operating switch in “down” position.
3. When the screen stops, turn the “down” limit knob (Fig. 2) one-quarter turn counterclockwise. Test by
raising picture surface approximately two feet, then lower again. Repeat until desired picture surface position is
attained.
NOTE: Must leave 1-1/2 wraps of fabric on roller!
4. Replace access panel.
LESS SCREEN DROP
1. Remove access panel. (Fig. 1).
2. Raise picture surface approximately two feet above desired level.
3. Place operating switch in “off” position.
4. Turn the “down” limit knob (Fig. 2) one-quarter turn clockwise. Test by raising picture surface approximately two
feet, then lower again. Repeat until desired picture surface position is attained.
