INSTALLATION INSTRUCTIONS
OPERATOR SUPPORT
1. The illustration below shows a typical method of
hanging the operator from the ceiling. Each installa-
tion may vary, but in all cases side braces should be
used for additional strength.
2. For mounting of the support brace(s) to the pow-
erhead, Four holes (clearance up to 3/8” bolts) are
located on each side of frame.
NOTE: If the operator is longer than 15 feet, use of a
mid-span support is recommended.
STRAIGHT ARM ATTACHMENT
1. Fully close the door and move the trolley slider to
within (2”) two inches of the front idler.
2. Latch the straight door arm to the fixed roll pin in
the trolley carriage. Make sure the open side of notch
on the arm faces the doorway.
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 brack-
et to the door. Many installations, except solid wood
doors, will require additional support for the door.
Refer to the illustration below.
IMPORTANT NOTE:
At this time, ensure all bolts and
lag screws are properly secured.
