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 rating
at least equal to that of the appliance should be used. Cords
rated for less amperage than the appliance may overheat.
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 ire, electric shock, or
injury to persons.

Pre-Installation
Installation
1. Carefully unpack screen and remove outer
wrapping from case.
2. Make sure to recheck measurement of screen
location before installation.
3. Remove center support brackets (on 8' and wider
screens only), reverse brackets and reinstall lush with
the top of the box.
NOTE: Unit is not to be installed in air handling space.
1. Install screen by raising unit into position between joists at
one end only. Install one lag screw or appropriate fastener in
each mounting bracket. Secure opposite end. Secure center
support brackets. Install suicient fasteners in each bracket
for secure installation.
2. Make sure unit is level and plumb.
CAUTION! Do not secure access door or seal in unit
until screen has been secured in position and properly
tested for satisfactory operation. Do not it unit so tightly
that the screen surface drop door binds. Door drops by
gravity only.
ATTENTION! Ne ixez pas la trappe d'accès ou ne scellez
pas l'unité jusqu'à ce qu'il ait été correctement mis en
place et qu'il fonctionne convenablement. Ne serrez pas
l'unité au point que la surface de la trappe d'accès de
l'écran soit bloquée. La trappe tombe uniquement à cause
de la gravité.
3. If you are going to cover screen door with paneling or other
materials, allow access (suitable holes or plug) to slat hook
screws (4) when servicing (Fig. 1).
4. Open access door by removing access door screws.
5. Remove junction box cover plate.

6. Remove switch assembly (boxed, located at pin end of fabric).
CAUTION! Do not cut wrapping paper or tape with knife or
any sharp tool. Remove by hand.
ATTENTION! Ne coupez pas le ruban adhésif sur la toile
avec un couteau ou un outil tranchant. Retirez à la main.
7. Pull orange string to remove wrapping paper.
8. Install electrical hook up that applies to your unit. Standard
installation is for a single 120VAC or 240VAC wall switch to
control the screen. Optional Control units may have been
ordered. Refer to additional instructions for the external VPI,
external low voltage control and SCB100. Refer to the
appropriate wiring diagram for your screen.
NOTE: Screen has been internally wired at DALITE. Wiring
designated “external” is completed by installer conforming to
local and national codes.
9. Lower picture surface approximately 4"-6" so that the slat will
rest on top of the slat hooks. Guide slat past hooks by gently
pulling fabric forward (Fig. 3). Do not bend hooks.
10. Test installation by carefully running picture surface up and
down 23 times. Be prepared to stop screen. Standard Duty
Cycle: 1 MIN. ON / 3 MIN. OFF.
11. Run the picture surface upward. The surface door will
automatically close when the picture surface rolls into the
case. The ends of the slat will catch the two hooks on the
surface door and pull the door closed. When the door closes,
a limit switch is tripped and the motor shuts of.
CAUTION! Excessive continuous operation may cause
overheating.
ATTENTION! Le fonctionnement continu et excessif peut
provoquer une surchaufe.
12. Run picture surface downward until picture surface
door fully opens.
13. Install junction box cover plate.
14. Close access door and reinstall screws at each end
of access door.
CAUTION! Do not attempt to restore a lost wrap by
adjusting limit switches. Allow one-eighth of an inch (1/8")
clearance around surface door. Make sure door does not
bind. Check hinges. Paint or tile cement will interfere with
free operation. Gravity drops door.
ATTENTION! N'essayez pas de réintégrer un tour de toile
en réglant les interrupteurs de limite! Laissez un espace
0,30 cm (1/8 po) autour de la trappe. Vériiez que la
trappe n'est pas entravée. Vériiez les gonds. La peinture
ou le ciment à tuile nuira au bon fonctionnement. La
gravité fait tomber la trappe.
15. Complete installation by painting and inishing to suit
your needs. Finish to allow access door to be removed
if necessary.
