Drawbar Installation
WARNING
Repairs and adjustments, including particularly to
cables and spring assemblies under high tension,
must be made by a trained service representative
using proper tools and instructions.
!
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,
page 5.7, 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 ax 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.
NOTE: On torsion spring doors with an uneven
number of panels, the operator may be
attached to the stile nearest to the center.
