Tools Required for Installation
Pre-Installation
1. Carefully unpack case from shipping carton.
2. Set aside the Installation Kit. Items inside will be used
during installation.
3. Make sure to recheck measurement of case for proper
installation clearance.
1/2“ Open Wrench
or Socket Driver
1/8” Hex Key
(included)
4. Remove any protective foam covering the outside
of the case.

brackets for mounting.
#2 Phillips Screwdriver
1. Hang case and attach to support structure with bolts. See
Suggested Methods of Installation.
2. Tighten bolts until trim lange is lush with ceiling.
NOTE: For proper operation, case must be levelled side to
side and front to back.
3. Loosen screw using a #2 Phillips screwdriver to slide
junction box door and rotate open. Install electrical
connections that apply to your unit. Make sure to review the
wiring diagram for proper hook up. Close junction box by
rotating lid and sliding over screw. Secure shut by fastening
closing screw. (Figure 1)
Case Installation
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.

Screen Adjustment
1. Locate the wall switch and remove the cover plate from the
wall switch and remove the switch from the junction box.
2. Locate the two tactile buttons on the back of the switch.
They are black round buttons on silver plates.
3. To adjust the down limit switch, press and hold the down
tactile button until the LED on the back of the switch turns
solid red. This will put the motor in limit set mode. Turn the
wall switch over and use the down button on the front of the
switch. Press and hold the down button until the desired
down position is reached. If you travel too far down, press the
up button to move the screen upward. If you press and let go
of either the up or down buttons, the motor will do a small
jog in that direction for ine adjustment of the screen. Once
the desired position is reached, turn the switch over; press
and hold the down tactile button until the LED on back of
switch blinks red twice. The down limit is now set.
CAUTION: Do not adjust for more drop than what was
ordered. At least 11/2 wraps of fabric must remain on
the roller.
ATTENTION! N'efectuez pas de réglage pour obtenir un
déroulement supérieur à celui commandé. Au moins 1 à
1/2 tour de toile doit être maintenu sur le cylindre.
NOTE: If the screen is in limit set mode and no buttons are
pushed for 20 seconds, the LED on the back of the wall
switch will turn of, the motor will return to run mode and no
changes will be saved. If this occurs, return to step 3 for down
limit adjustment or step 4 for up limit adjustment.
4. To adjust the up limit switch, press and hold the up tactile
button until the LED on the back of the switch turns solid
green. This will put the motor in limit set mode. Turn the wall
switch over and use the up button on the front of the switch.
Press and hold the up button until the desired up position is
reached. If you travel too far up, press the down button to
move the screen downward. If you press and let go of either
the up or down buttons, the motor will do a small jog in that
direction for ine adjustment of the screen. Once the desired
position is reached, turn the switch over; press and hold the
up tactile button until the LED on back of switch blinks green
twice. The up limit is now set.
5. To test the limit switch settings, press and release the up or
down buttons on the switch to operate the screen.
6. Replace the switch and cover plate on the wall.
IMPORTANT NOTE: The wall switch is REQUIRED to make
any limit switch adjustments, even if a third party control
system is used. Therefore, it is advised to wire the switch or
provide a 3-conductor connection that is accessible.
Tensioned Screens
Models with tab-tensioned surfaces are standard with 12" of black
drop at the top.
CAUTION: Adjusting the down limit switch for less drop
by more than 6" can cause the screen surface to lose
proper tensioning.
ATTENTION! LE FAIT D'AJOUTER NE DÉROULEZ PAS

NonTensioned Screens
Non-tensioned screens are pre-set with 2" of black drop at the
top with a total of 12" of fully adjustable black drop available.

Third Party Control
Control Panel
A control panel may be connected to the splitter board by using
the dry contact Up, Down and Common connections. The
control panel must provide a momentary, dry contact closure of
at least 1/2 second.
1. Use 3-conductor 2024 gauge wire to connect the control panel
to the splitter board.
2. A momentary closure across the common and up wires will be
an “up” command.
3. A momentary closure across the common and down wires will
be a “down” command.
4. A momentary closure across the common, up and down wires
will be a “stop” command.

Troubleshooting
Symptom Cause Solution
Screen will not operate
and motor does not hum.
Incorrect line voltage. Verify 115125V (or 220240V). If insuicient voltage, rewire
incoming electric line.
Blown fuse. Replace fuse.
Tripped circuit breaker. Reset circuit breaker.
No power to operating switch
or junction.
Check above. Tighten all loose wire connections.
Correct any improper connections.
Down Position
Check for power across black and white leads.
