PRE-INSTALLATION
1
1. Carefully unpack screen and remove outer wrapping from case.
2. Remove fabric and cardboard strips from access door.
3. Remove access door by gently prying from middle section.
4. FOR TYPE 3 INSTALLATION ONLY, remove wood strips along bottom edge of screen case.
5. Remove instruction cover (Fig. 1). Remove, reverse, and remount Center Support Brackets.
6. Do not remove metal shipping brace (secures roller), wrapping paper or tape until screen is installed.
NOTE: Screen is not centered in box. Screen is set 22" from motor end.
7. Make sure to recheck measurement of screen location before installation.
INSTALLATION
1. Install screen by raising unit into position between joists at one end only. Install one lag screw in each mounting
bracket. Secure opposite end. Support center of the screw using the brackets.
2. Level unit lengthwise with a carpenter’s level and a plum level.
CAUTION! DO NOT SECURE ACCESS DOOR OR SEAL IN UNIT UNTIL SCREEN HAS BEEN SECURED IN POSITION AND PROP-
ERLY TESTED FOR SATISFACTORY OPERATION. DO NOT FIT UNIT SO TIGHTLY THAT THE SCREEN SURFACE DROP DOOR BINDS.
DOOR DROPS BY GRAVITY ONLY.
3. If you are going to cover screen door with paneling or other materials, allow access (suitable holes or a plug) to
screws when servicing.
4. Remove shipping brace by removing 3 hex head screws (Fig. 2).
CAUTION! DO NOT CUT WRAPPING PAPER OR TAPE WITH KNIFE OR ANY SHARP TOOL. REMOVE BY HAND.
5. Remove tape strips and release fabric (Fig. 2). Picture surface should hang freely (Fig. 3). Remove any tape left
hanging on back of fabric. Bottom edge should be positioned between bottom edge of case and center of roller.

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 subse-
quently.
5. The use of an accessory attachment not recommended by the manufacturer may cause a risk of fire, electric
shock, or injury to persons.
SAVE THESE INSTRUCTIONS

SCREEN ADJUSTMENT
The picture surface drop, and the opening and closing of the fabric door, are controlled automatically by limit switches
which have been preset at Da-Lite. When the picture surface is moving upward, it is controlled by a limit switch that
shuts off when the door closes. To adjust for more or less picture drop (viewing area), proceed in the following manner:
SCREEN UNROLLED IN “DOWN” OR “BOTTOM” POSITION.
NOTE: Limit switch knob labeled DOWN controls point of picture surface in bottom position. Limit switch knob labaeled DOOR con-
trols the synchronization of the door opening or closing. Do not adjust!
MORE SCREEN DROP
1. Place operating switch in “down” position.
2. When the screen stops, turn the “down” limit knob one turn at a time
clockwise, until the desired picture surface position is attained. Test
by raising picture surface approximately two feet, then lower again.
Repeat until desired picture surface position is attained.
CAUTION! WHEN PICTURE SURFACE IS IN “BOTTOM” POSITION, DO NOT
ADJUST FOR MORE THAN 3" OF ADDITIONAL DROP. DO NOT ALLOW ANY
PART OF THE ROLLER TO BECOME EXPOSED.
LESS SCREEN DROP
1. Raise picture surface approximately two feet above desired level.
2. Place operating switch in “off” position.
3. Turn the “down” limit knob one turn at a time counter-clockwise.
4. Place operating switch in “down” position. Repeat steps 2 and 3 until desired position is attained.

ACCESS DOOR INSTALLATION
1. Press switch “down” so that fabric door opens (Fig. 3).
2. Remove screws (2) located on each bumper bracket.
NOTE: The access door is slotted on one edge, permitting the grooved section to fit over the support clips on inside of case.
3. Place access panel so groove can be pushed over clips. Holes in access panel brackets should align with bumper
bracket holes.
4. Replace screws.
5. Make sure there is approximately 3⁄16" clearance around access door. Keep paint, plaster, tile or mastic out of hinge.
Fit access panel so it can be removed for maintenance.
NOTE: If picture surface is hanging out of case approxi-
mately 12”, a wrap of the picture surface has been lost
from around the roller; see, “Restoring Roller Wrap”.
.6.Install electrical hook up that applies to your unit.
7. Test installation by carefully running picture sur-
face “up” and “down” several times. Be prepared
to stop screen.
8. Make sure picture surface, when rolled down, has
a full wrap around roller. No part of roller should
be exposed. Fabric door and picture surface will
drop simultaneously when switch is pressed
“down”. Door will close simultaneously with pic-
ture surface as picture surface rolls into case.
