CAUTION : Check the working condition of
the door before installing the operator. The Door must be
free from sticking and binding. If the door is equipped
with a latching device, secure the locking bar in the open
(unlocked) position.
If the door lock is to remain functional, an interlock switch
MUST be installed which will prevent operation of the door
whenever the door lock is engaged. Refer to the Wiring
Instructions, section 5.5, of this manual for proper
connection of the interlock switch.
1) Measure the width of the door to determine the center. Make a vertical
line above the door, as shown in Fig. 7. (If the vertical line is not in line with
a door stile, a means of attaching the door bracket to the door must be
provided. This can be accomplished by spanning the center of the door’s
top section (between the top and bottom rail) with a suitable material
such as wood or steel).
2) Prepare for attaching drawbar to header. If woodwork, or other suitable
material is not already in place, securely affix a 2” x 6” block of wood or
metal plate as shown in Fig. 7.
3) Center the block/plate on the header.
4) Mark the door’s vertical center line on this block/plate.
5) Use a level, as shown in
Fig. 8 (pg 4.6) to find the highest point of travel
for the the door.
6) Mark a horizontal line across the vertical line you made on the header
at 5” above the highest point of door travel.
