should always be followed, including the following:
1. Read and understand all instructions before using.
2. Close supervision is necessary when any appliance is used
by or near children. Do not leave appliance unattended while
in use.
3. Do not operate appliance with a damaged cord or if the
appliance has been dropped or damaged – until it has been
examined by a qualiied serviceman.
4. Position the cord so that it will not be tripped over, pulled, or
contact hot surfaces.
5. 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.

appliance in water or other liquids.

appliance. Contact an authorized service dealer when repair
work is required. Incorrect reassembly can cause electric
shock when the appliance is used subsequently.

the manufacturer may cause a risk of ire, electric shock, or
injury to persons.

Case Installation
1. The case provides multiple attachment points for bolts,
cables, or threaded rod. Page 5 shows threaded rod installed.
The variable position-mounting bracket may be located
anywhere along the length of the case. It is recommended to
keep the brackets spaced evenly enough to distribute the
weight of the screen. One mounting bracket is required for
every 4' of case length.
The case has a self-trimming lange around the bottom.
Ceiling tiles or drywall may be placed on top of this lange to
provide a inished appearance.
2. After securing the case in the ceiling check that the case is
level and plumb.

Screen And Roller Assembly Installation
If your screen was shipped with the motor and roller already installed proceed to step 7.
1. Remove four bolts from ends of door assembly (2 bolts on
each end) (Fig. 1). This will allow the door assembly to drop
open for access to case. For larger sizes, you will also need to
remove the door support screws.
2. Carefully unpack screen and roller assembly. Leave packing
paper on the roller.
3. Remove the square peg bracket from the motor end of the
roller assembly.
4. Remove the safety clip from the motor attachement bracket
located in the motor end of the screen housing.
5. Place the roller assembly into the case with the motor on the
left side. The limit switches should be facing down. Line up
the head of the motor with the motor attachment bracket.
6. Loosen four bolts that secure pin end mounting bracket into
housing. Lift pin end of roller into position and slide the
bracket into the roller pin. Tighten all four bolts.
7. Complete electrical hook-up by snapping motor 1/3 wire
connectors into case connectors.
8. Return to motor end and insert safety clip over casting
bracket to secure motor end.
CAUTION! Do not cut tape on fabric with a knife or any
sharp tool. Remove by hand.
9. Carefully remove tape strips securing picture surface around
roller. Slat should move freely (Fig. 2). (Only if the roller
assembly is pre installed.)
10. Test installation by operating the screen several times. Be
prepared to stop the screen. The door assembly will not
close until the wall switch is placed in the up position and
when the screen motor stops at its limit switch in the up
direction.
NOTE: Unit duty cycle is 1 minute on, 3 minutes of.
NOTE: Excessive continuous operation may cause the motor
to overheat. If this happens the motor will shut of until it
cools to a normal operating temperature.
