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 fire, electric shock, or injury to persons.

SAVE THESE INSTRUCTIONS

PRE-INSTALLATION

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 (securs roller), wrapping paper or tape until screen is installed.

NOTE: Screen is not centered in box. Screen is set 22^ from motor end.

1. 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 ACCESSOR SEAL IN UNIT UNTIL SCREEN HAS BEEN SECURED IN POSITION AND PROPERLY TESTED FOR SATISFACTORY OPERATION. DO NOT FIT UNIT SO TIGHTLY THAT THE SCREEN SURFACE DROP DOOR BINDS. DOOR DROPS BY GRAVITY ONLY.

1. If you are going to cover screen door with paneling or other materials, allow access (suitable holes or a plug) to screws when servicing.
2. 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.

1. 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.

2. Install electrical hook up that applies to your unit. Unit should be installed by a qualified electrician.
   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.

3. Test installation by carefully running picture surface "up" and "down" several times. Be prepared to stop screen.
4. 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 picture surface as picture surface rolls into case.

FIG.3

NOTE: If picture surface is hanging out of case approximately 12^ , a wrap of the picture surface has been lost from around the roller; see, "Restoring Roller Wrap".

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.

1. Place access panel so groove can be pushed over clips. Holes in access panel brackets should align with bumper bracket holes.
2. Replace screws.
3. 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.

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 labeled DOOR controls 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.

CAUTION! DO NOT ATTEMPT TO RESTORE A LOST WRAP BY ADJUSTING LIMIT SWITCHES!

1. Run fabric all the way down.
2. Run fabric up and stop just before door closes.
3. Remove the access panel (2 screws, Fig. 3).
4. Two people with clean hands must carefully grasp the slat pocket at each end.
5. Gently lift fabric up and ease it over the top of the roller.

CAUTION! BE CAREFUL NOT TO CREASE OR DAMAGE FABRIC.

1. Additional wraps must be restored if screen surface continues to hang beyond bottom of case.
2. Test screen by running fabric up and down several times.
3. Replace access panel.
