ASSEMBLE DOOR ARM AND SET LIMITS
NOTE: For one piece doors, do not connect door arm to trolley
before adjusting limits. Failure to follow instructions may result
in damage to door. See below.
A. ONE-PIECE DOOR INSTALLATION:
Connect straight door arm (1) and curved door arm sections (2) to
obtain the longest possible length with hardware (3, 4, 5). With door
closed, connect straight door arm section to door bracket with a
clevis pin (6). Secure with a ring fastener (7).
Before connecting door arm to trolley, adjust travel limits. Limit
adjustment screws are located on side panel.
Open Door Adjustment: Decrease up limit. Turn up limit adjustment
screw counterclockwise 5-1/2 turns.
Press door control button. Trolley will travel to full open position (8).
Manually raise door to open position (parallel to floor) and lift door
arm (9) to trolley. The arm should touch trolley just in back of door arm
connector hole (10) as shown in solid line drawing. Increase up limit
if necessary. One full turn equals 5cm (2") of door travel.
Closed Door Adjustment: Decrease down limit. Turn down limit
adjustment screw clockwise 5 complete turns.
Press door control button. Trolley will travel to full closed position (11).
Manually close door and lift door arm (12) to trolley. The arm should
touch trolley just ahead of door arm connector hole (13) as shown in
dotted line drawing. Decrease down limit if necessary. One full turn
equals 5cm (2") of door travel.
Connect Door Arm to Trolley: With door closed, connect curved arm
to trolley with remaining clevis pin. Secure with ring fastener. Note:
Lift door slightly to make connection if necessary.
Run opener through a complete travel cycle. If door has a slight
"backward" slant in full open position, decrease up limits until door is
parallel to floor.
B. SECTIONAL DOOR INSTALLATION:
Connect according to Figure B, then proceed to Step 18.
PROGRAM YOUR OPENER & REMOTE
Activate the opener only when door is in full view, free of
obstruction and properly adjusted. No one should enter or leave
garage while door is in motion. Do not allow children to operate
push button(s) or remote(s). Do not allow children to play near
the door.
Your garage door opener receiver and remote control transmitter are
set to a matching code. If you purchase additional remote controls, the
garage door opener must be programmed to accept the new remote
code.
Program the Receiver to Match Additional Remote Control Codes
1. Press and hold the remote control push button (1).
2. Press and release the "Smart" button (2) on the opener panel. The
opener light will flash once.
3. Release the remote push button.
Now the opener will operate when the remote control push button is
pressed.
If you release the remote control push button before the opener
lights flash, the opener will not accept the code.
To Erase all Remote Control Codes
• Press and hold the "Smart" button on the opener panel until the
indicator light turns off (about 6 seconds). All the codes the opener
has learned will be erased.
• To reprogram, repeat Steps 1 – 3 for each remote control in use.
17 ADJUSTMENT SECTION
LIMIT ADJUSTMENT
Run the opener through a complete travel cycle. Limit adjustments
are not necessary when the door opens and closes completely and
doesn't reverse unintentionally in the fully closed position.
Situations requiring limit adjustment are listed below. Run the opener
through a complete travel cycle after each adjustment.
Note: Repeated operation of the opener during adjustment
procedures may cause motor to overheat and shut off. Allow a
15 minute cooling period after 5 continuous operations of the
opener.
Read the following carefully before proceeding to Force
Adjustment. Use a screwdriver to make limit adjustments.
If Door Doesn't Open Completely but Opens at Least 1,5m (5
feet): Increase up travel. Turn the up limit adjustment screw (1)
clockwise. One turn equals 5cm (2") of travel.
If door does not open at least 1,5m (5 feet): Adjust up (open)
force. See Force Adjustment.
If Door Doesn't Close Completely: Increase down travel. Turn
down limit adjustment screw (2) counterclockwise. One turn equals
5cm (2") of travel. If the door still will not close completely, lengthen
the door arm. If it still will not close completely, lower the header
bracket.
If Opener Reverses in Fully Closed Position: Decrease down
travel. Turn down limit adjustment screw (2) clockwise. One turn
equals 5cm (2") of travel.
If Door Reverses when Closing and there is no Interference to
Travel Cycle: Test door for binding. Pull manual release handle.
