Installation Guidelines:
-
Cut the ADB (Automatic Door Bottom) according to the required length.
Make sure to only cut from the side with no plunger.
For surface application: Cut the ADB approximately 1/32” shorter than the opening of the door. The cut must be beveled 1/8“, see illustration 3.
For Semi-Mortise application: ADB must be the same length as the door, less than 1/32”.
Reminder: If the door is fire labeled, mortise preparation must be done by the door manufacturer to ensure compliance with door standards.
Note: The cut should not be less than 1-1/2” before the set screw. See Illustration 4. -
Place the ADB on the push side of the door. Make sure that the bottom of the aluminum is parallel to the surface of the floor. You may use a 1/4” to 3/8” height shim to keep the unit off the floor during installation.
-
Fasten unit with screws provided. The ideal clearance between the unit and finished floor is 3/8”.
-
Set the ADB by turning the actuating plunger clockwise or counterclockwise until the rubber seal gasket touches the floor surface.
-
Lastly, install the endplate on both ends of ADB.
a) Surface Mounted: the plunger contacts the stop.See illustration #1.
b) Semi-Mortised: the plunger contacts the rabbet. See illustration #2.
