Pre-Installation

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.

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.

5. FOR TYPE 3 INSTALLATION ONLY. Remove wood strips along

bottom of screen case.

NOTE: Screen surface is not centered in box. Screen surface

is 25" from motor end.

6. Make sure to recheck measurements of screen location

before installation.

7. Remove, reverse, and remount center support brackets.

Installation

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 satisfactory operation. Do not it unit so tightly

that the screen surface drop door binds. Door drops by

gravity only.

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. Use supplied 1/8” nex key and a 7/16” wrench to remove silver

shipping brackets attached to slat and screen case.

6. 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.

7. Install electrical hook up that applies to your unit. Unit should

be installed by a qualiied 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.

8. Test installation by carefully running picture surface “up” and

“down” several times. Be prepared to stop screen. Fabric door

must open freely to 90˚.

9. 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.

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 it 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.

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 of 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.
