Before You Begin...
For the Automatic Gate Lock to work properly, the gate must close firmly against a positive stop and engage
the lock catch against the lock receiver. Achieving optimal closure may require slight adjustments to the gate
opener settings.
Installing the lock with the Gate Opener may require adjusting limits and stall force.
Refer to your individual gate opener installation manual for information on these adjustments.
Set the limits so that the arm holds the gate snug against the stop in the closed position.
IMPORTANT:
You
may need to spray the locking mechanism with silicone spray initially to help the latch move freely.
If you are installing the lock on a Push-to-Open gate (gate opens out), the lock must be installed on
the outside of the gate. Depending upon the installation, the gate post may need to be "pocketed" to
accommodate the lock receiver. Contact the Nortek Control Technical Service Department at (800) 543-1236
for assistance if needed.
NOTE: Positive stops are required for dual gate applications.
