IMPORTANT NOTE: Before your operator is installed, be sure the door has been properly aligned and is working smoothly. The
operator may be wall mounted or mounted on a bracket or shelf. If necessary, refer to the preparation on page 5. Refer to the
illustrations and instructions below that suit your application.
MOUNT THE HEADER BRACKET
1. Close the door and mark the inside vertical centerline of the
door.
2. Extend the line onto the header wall above the door.
You can fasten the header bracket within 2' (.61 m) of the
left or right of the door center only if a torsion spring or
center bearing plate is in the way.
3. Open your door to the highest point of travel as shown. Draw
an intersecting horizontal line on the header wall 4" (10.2 cm)
above the high point. This height will provide travel clearance
for the top edge of the door.
MOUNT THE OPERATOR
1. Position the operator on the floor below the header bracket.
2. Position the front idler assembly against the header bracket.
3. Align the bracket holes and join with hardware as shown.

Operator Alignment
4. Raise the operator to a horizontal position above the guide rails
and temporarily secure with a suitable rope, chain, or support
from the floor. Open door slowly, being careful not to dislodge
the temporary support. Using the door as a support, place a
level against the rail and shim the operator until it is horizontal.
Make sure that the operator is aligned with the center line of
the door.
4. Using the projected lines for location, mount a suitable wood
block or length of angle iron to the wall above the door
opening. Refer to the illustration below. This will provide a
mounting pad for the front header bracket of the operator. If
necessary reinforce the wall with suitable mounting brackets to
ensure adequate support of mounting pad. Using suitable
hardware, mount the (U-shaped) front header bracket to the
pad.
