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
1. Carefully unpack screen.
2. Make sure to recheck measurements of screen location
before installation.
3. Remove instruction cover plate (Fig. 1). Do not remove
wrapping paper or tape strips until screen is installed.
Ironing Board
Professional Electrols 14' and over contain an ironing board to
latten the fabric (long strip attached). The ironing board is part
of the screen case. Do not remove. Contact Da-Lite if the ironing
board is in need of adjustment. (Fig. 2).

Installation
Ceiling Mount
Without Hangers
Screen case is placed lush with
the wall and ceiling and held in
position by moulding securely
attached to the wall.
Recessed Above Ceiling
Other methods of installation
will suggest themselves in new
buildings where it would be an
easy matter to provide a recess
for the screen to conceal it when
not in use.
Do not seal in—allow access.
Wall or Ceiling Mount With Hangers
Wall type hangers and ceiling type hangers are
standard equipment. One set is supplied with
each screen. Useful for recessed installations.
Wall Type Hanger
NOTE: For Exposed Installation If the screen is to be mounted
in an exposed position, it may be covered with inished plywood,
veneer, paneling, plastic wall covering or a valance.

switch, or DRC low voltage control.
7. Test installation by carefully running surface up and down
several times. Be prepared to stop screen.

CAUTION! When adjusting and testing, be prepared to
stop screen quickly as serious damage may occur.
ATTENTION! Lors du réglage et du test, soyez prêt à
rapidement arrêter l'écran car de graves dommages
peuvent se produire.
NOTE: Use a screw driver or allen wrench to make adjustments.
More screen drop
1. Place operating switch in “down” position.
2. When the screen stops, turn the white “down” limit knob
(Fig.4) 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 at least 11/2 wraps of fabric on roller.
Less screen drop
1. Raise picture surface approximately two feet above
desired level.
2. Place operating switch in “of” position.
3. Turn the white “down” limit switch (Fig. 4) one-quarter turn
clockwise. Test by raising picture surface approximately two
feet, then lower again. Repeat until desired picture surface
position is attained.
