Tips

Proper installation is key to optimal performance. Always follow the included template for alignment and ensure the door frame is sufficiently sturdy. Adjust the speed, latch, backcheck, and delayed action valves in small increments and test the motion until the door moves smoothly without slamming. Regular cleaning of the arm and pivot points will extend the service life. For fire-rated installations, verify local codes and ensure the closer is configured correctly.
