1 Installation Instructions
WARNING
HAZARDOUS VOLTAGE CAN SHOCK AND CAUSE SEVERE INJURY
Disconnect power before making any electrical connections
or performing maintenance.
1a Closer is handed at factory and marked with an “R”
or “L” on top of packing nut. The hand of closer must
match hand of door (See door handing diagram on
page 1).
1b Input voltage supplied to door frame must be
24V. Determine whether the wiring will be concealed
or surface run, and follow the remaining instructions
carefully.
1c FOR CONCEALED WIRING: See Figure 2 on page 3.
a. Prepare frame per proper template on page 6. Be sure
all the holes are dimensioned correctly before drilling and
tapping.
b. Assemble conduit connector provided to exible conduit,
then attach to hole in mounting plate.
c. Secure mounting plate to frame with screws provided.
1d FOR SURFACE WIRING: See Figure 3 on page 3.
LNOTE: Remove knockout in top of cover.
a. Prepare frame per proper template on page 6. Be sure all
holes are dimensioned correctly before drilling and tapping.
b. Secure mounting plate to frame with screws provided.
c. Attach the surface run 1/2” EMT conduit to hole in bracket
on mounting plate. Be sure conduit is securely attached to
bracket.
1e Make wiring connections at this time. Connect two
black wires to 24V input voltage. Green wire MUST be
connected to an earth ground. See Figure 2 or 3 on
page 3.
1f Place arm shaft spacer on closer shaft, then place arm
on closer shaft and secure with arm shaft screw.
1g Remove end cap from track and insert track roller.
Reinsert end cap into end of track and insert track
plugs. Using fasteners provided, mount track to door
per template on page 6.
1h Loosen set screw in end of arm, open door approx.
30°, pull ar m over top of door and connect to track
roller. Tighten set screw rmly.
1i Spring Power Adjustment: See Figure 1 for spring
power adjustment diagram. To adjust spring power,
use a 5/32” allen wrench provided to turn spring
adjustment nut clockwise or counter clockwise the
required number of turns to match the door width in
Spring Adjustment chart on page 6. DO NOT exceed 7
turns c.w. or 8 turns c.c.w. direction.
CAUTION
Improper installation or regulation may result in personal
injury or property damage. Follow all instructions
carefully. For questions, call LCN at
877 - 671 - 7011
1j Closing Speed Regulation is preset at factory.
Normally no adjustment is required, if desired: adjust
Main and Latch Speed by turning proper regulating
screw (see Figure 1) clockwise to slow speed or
c.c.w. to increase speed. Do not allow door to slam
into frame. A “normal” closing time from a 90° position
is 5 to 7 seconds, equally divided between Main and
Latch Speed. When adjusting the Backcheck use the
least amount of force necessary to sufciently retard
the swing of the door. To adjust Backcheck, turn
regulating screw clockwise to increase amount of force
or c.c.w. to reduce the amount of force. Do not use
abrupt backcheck setting or expect closer to act
as a stop!
1k Perform electrical checkout on page 4 before installing
closer cover.
