HANG THE OPERATOR
1. The illustration below shows a typical method of hanging the
operator from the ceiling. Each installation may vary, but in all
cases side braces should be used for additional strength.
2. For mounting of the support brace(s) to the powerhead. Four
holes (clearance up to 3/8" bolts) are located on each side of
frame.
3. Check to make sure the track is centered over the door (or in
line with the header bracket if the bracket is not centered above
the door).
NOTE: If the operator is longer than 15' (4.57 m) use of a
mid-span support is recommended.
STRAIGHT ARM ATTACHMENT
1. Fully close the door and move the trolley slider to within 2"
(5.08 cm) of the front idler.
2. Attach straight door arm to the fixed roll pin in the trolley
carriage.
3. Attach the door bracket to the door arm using the 3/8"-16 x 1"
bolt and nylon locking nut provided. Leave the nut and bolt
loose enough to allow the two pieces to pivot freely.
4. Using 3/8" hardware provided, bolt the curved door arm to the
straight arm, aligning the mounting holes in such a way that
the door bracket pivot bolt will be in line with the top rollers on
the door.
5. Position the door bracket to the center line on the door. Using
suitable hardware, attach the door bracket to the door. Many
installations, except solid wood doors, will require additional
support for the door. Refer to the illustration below.
NOTE: At this time, ensure all bolts and lag screws are properly
secured.
