Increase the
arresting force by turning the valve clockwise with the supplied hex key. Do not completely close the
valve. Do not use this valve if a delay action is used.

backward movement is not used. The delay action means that the door moves slowly to 70°. Increase the
delay action by turning the valve clockwise. Do not completely close the valve.
Testing
1.
Open the door completely and release. The door should close all the way to the frame and lock.
2.
Open the door and allow the lock cylinder to rest against the lock plate. The door should lock when
you release it.
If the door does not close it may be necessary to increase the closing force, or adjust
the alignment of the
door in the frame.
