CAUTION
Check the working condition of the door before installing the
operator. 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. This style operator will act as a
latching device when the door is down and therefor the door’s
lock is no longer needed.
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 as shown in
Fig. 7
. (If the vertical line is not in line
with a door stile, a means of attaching the spring box 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.
NOTE
: On torsion spring doors with an uneven number of panels, the
operator may be attached to the stile nearest to the center.
2) Prepare for attaching drawbar to header. If suitable woodwork is
not already in place, securely affix a 2" x 6" block of wood as
shown in
Fig. 7
.
3) Center the block on the header.
4) Mark the center vertical line on this block.
5) Use a level, as shown in
Fig. 8 (pg 4.6)
to find the highest point
of travel for the door.
6) Mark a horizontal line across the vertical line you made on
the header at 2-1/2" above the highest point of door travel.
