1 Lay out the two pieces of track on the fl oor, parallel to each
other and install the end idler shaft assembly.
2 Install the track hangers with 3/8" hardware. The number of
track hangers will vary with the door width. The holes in the
track for the track hangers are pre-punched and are generally
about 5 feet (1.5 m) apart.
3 Install the take-up bolt on the trolley with two 3/8" hex nuts
and lock washers. Slide the trolley onto the track so that the
take-up bolt will be facing the operator.
NOTE: For bi-parting doors, slide the bi-part trolley into the
track assembly first, so the bi-part trolley is closest to the
front idler.
4 Install one fi nal track hanger on the back of the operator.
Remove the spacer bar which comes assembled in the frame
of the operator. Position the track assembly on the operator
and reinstall the spacer within the rails, tightening the bolts
securely. For a right-to-open single sliding door, the operator
should be mounted on the right-hand end of the track with the
pulleys facing out. Install two 3/8"-16 x 1" hex bolts with lock
washers and nuts through the remaining two mounting holes
in the operator.
5 Attach the chain to the take-up bolt on the trolley using the
master link. Reel the chain around the drive sprocket, up to
the idler shaft and then back to the hole on the front of the
trolley.
6 Using the two 10-32 x 1-1/4" screws and hardware, attach the
chain to the front end of the trolley. It may be necessary to
remove some links for proper tension. Tighten the chain by
adjusting the take-up bolt. A properly adjusted chain will sag
about 3 inches (7.6 cm) at the midpoint of the track.
NOTE: Leave the bi-part trolley free at this time.
7 Bolt the angle mounting brackets to the track hangers through
the slots in the angle mounting brackets. Use the 3/8"-16
hex head bolts with fl at washers under the heads and lock
washers and nuts under the track hangers. Do not tighten as
the distance from the wall to the track will have to be adjusted
later.

To prevent possible SERIOUS INJURY or DEATH:
• DO NOT connect electric power until instructed to do so.
• If the door lock needs to remain functional, install an interlock
switch.
• ALWAYS call a trained door systems technician if door binds,
sticks or is out of balance. An unbalanced door may not
reverse when required.
• NEVER try to loosen, move or adjust doors, door springs,
cable, pulleys, brackets or their hardware, ALL of which are
under EXTREME tension and can cause SERIOUS PERSONAL
INJURY.
• Disable ALL locks and remove ALL ropes connected to door
BEFORE installing and operating door operator to avoid
entanglement.
• Fasten the operator SECURELY to structural supports of the
building.
• Concrete anchors MUST be used if installing ANY brackets.
