INSTRUCTION BOOK FOR

Professional Electrol®

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.

Save These Instructions

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).

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.
