INSTALLATION INSTRUCTIONS
OPERATOR SUPPORT
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.
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 bracket 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.
FAILURE TO SUSPEND THE OPERATOR SECURELY MAY
RESULT IN SERIOUS PERSONAL INJURY OR DEATH,
AND/OR PROPERTY DAMAGE.
