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 specifications shown on the
corresponding template. If surface wiring is desired, be sure to
mount the track on the frame before running any EMT/conduit.

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

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.

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 sufficiently. 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!
