1. Position screen under mounting location with the case opening down.

2. 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 screen using the brackets.

3. 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 properly tested for satisfac-

tory operation. Do not fit unit so tightly that the screen surface drop door binds. Door drops by gravity only.

▲

1. Carefully unpack screen and remove outer wrapping from case.

2. Remove instructions cover and please read instructions. (Fig. 1)

3. Remove fabric and cardboard strips from access door. (Fig. 1)

4. Remove access door by gently prying from edge of box toward the fabric door.

IMPORTANT SAFETY INSTRUCTIONS

When using your video equipment, basic safety precautions should always be followed, in-

cluding 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 over-

heat.

4. To reduce the risk of electric shock, do not disassemble this appliance. Contact an autho-

rized 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

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. The height for tensioned screens are adjusted at Da-Lite, changing the height of screen

will change the tension on fabric and cause the screen to hang improperly. Do not adjust.

ACCESS DOOR INSTALLATION

SCREEN ADJUSTMENT

1. Press switch “down” so that fabric door opens (Fig. 2).

2. Remove screws (2) located on each bumper bracket.

NOTE: The access door is slotted on one edge, permitting the slotted section to fit over the access panel clips on inside of case.

3. Place access panel so slot 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.

INSTALLATION

4. If you are going to cover screen door with paneling or other materials, allow access (suitable holes or a plug) to

screws for servicing.

5. Picture surface should hang freely. (Fig. 2) Remove any tape left hanging on back of fabric. Bottom edge should be

positioned between bottom edge of case and center of roller.

6. Install electrical hook up that applies to your unit.

7. Test installation by carefully running picture surface “up” and “down” several times. Be prepared to stop screen.

Fabric door must open freely to 90˚.

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 simultane-

ously with picture surface as picture surface rolls into case.
