INSTALLATION STEP 1
Position the Opener
1. Close the door completely.
2. Slide the opener with collar over the end of the torsion
bar. Ensure that the collar does not touch the bearing
plate. Check to make sure the mounting bracket is
located on a solid surface such as wood, concrete or
door/flag bracket. Snug collar screws to help assure
proper alignment of opener. Mark the bracket holes. It
may be necessary to cut the torsion bar if it is too long
or damaged.
3. Loosen collar screws from torsion bar and remove the
opener. Drill 5mm (3/16") pilot holes at the marked
locations. Drill through steel plate if needed.
4. Reinstall the opener by sliding the collar over the torsion
bar until pilot holes align with bracket. Securely tighten
collar screws that attach to the torsion bar to 16Nm-
19Nm of torque. Securely tighten both set screws firmly,
without damaging the opener.
5. Fasten bracket securely with 14-10x1-7/8" screws.
Tighten all mounting bracket hardware.
NOTE: The opener does not have to be flush to wall,
but it is essential it is mounted perfectly square to the
torsion bar. This will ensure smooth operation with
minimum stress at the connecting collar mount.
6. Use a staple to secure the antenna wire to prevent
antenna from being entangled in a door roller.
