4040SE
Installation Instructions
1 Voltage
The voltage shown on the track cover plate must match voltage
supplied to door frame (24V or 120V). If concealed wiring is
desired, prepare the frame to specications shown on the
corresponding template. If surface wiring is desired, be sure to
mount the track on the frame before running any EMT/conduit.
2 Track
Insert the proper track plugs into the top of the track. Using the
fasteners provided, mount the track on the frame to the template
dimensions being used. Make the electrical connections (see page
2).
3 Spring Power
Before mounting closer, the spring power may need adjusting.
Refer to the label on the closer spring tube. The 4040SE DE Series
comes preset at size 3. This will control a door up to 38”, adjust
the closer as shown (see illustration to the right) up to 7 full turns.
Starting the cover screws at this point is recommended. Using the
fasteners provided, mount the closer on the door to the dimensions
of the template being used.
4 Arm Installation
Place the arm spacer over the top shaft of the closer. Install the
arm as follows:
Place the arm spacer over the top shaft of the closer. Rotate the
arm from the door until ats in the arm hub line up with the rst
available ats of the shaft. Slide the arm hub onto the closer shaft.
Inser the shaft screw and tighten securely.
5 Arm Screw
Loosen the set screw in the arm. Connect the arm to the track
roller, and tighten the set screw rmly.
6 Door Position
To adjust the hold-open position of the door: Remove the screw
in the adjustable arm, and open the door to the desired position.
Reinsert the screw and tighten securely.
7 Regulation
Do not allow the door to slam into the frame. A “normal” closing
time from a 90° position is 5 to 7 seconds, evenly divided between
the Main and Latch Speed. If adjustments are needed, use a C\cx"
hex wrench. To adjust the Main Speed, turn the regulating screw
(see illustration) clockwise to slow the speed or c.c.w. to increase
the speed. Latch Speed is adjusted in the same way. When
adjusting, use the Backcheck the least amount necessary to slow
the swing of the door sufciently. To adjust the Backcheck, turn the
regulating screw clockwise to increase the amount of force or c.c.w.
to reduce the amount of force.
L NOTE: Do not use an abrupt backcheck setting or expect
the door closer to act as a stop!
8 Door Closer Cover
With regulation done, place the snap-on clip insert into the proper
cutout, then the snap cover assembly onto the spring tube.
CAUTION
Improper installation or regulation may result in personal
injury or property damage. Follow all instructions carefully.
