ŸAn improperly installed or incorrectly adjusted door closer may cause property
damage or personal injury; and will void product warranty.
ŸTo avoid personal injury, DO NOT DISASSEMBLE THIS DOOR CLOSER BODY.
ŸDoor closers must be securely fastened to a properly reinforced door and frame with
fasteners provided.
ŸThe Americans with Disabilities Act (ADA) requires that interior doors, other than fire
doors, have an opening force not to exceed 5 lbf as measured 1" from the latch edge
of door; force measurement starting 3" from jamb up to 70° of opening These forces
do not apply to the force required to retract latch bolts or disengage other devices that
hold the door or gate in a closed position.
ŸThe door closer's power size adjustment feature may require adjustment to its lowest
setting to comply with ADA opening force guidelines.
ŸLow opening forces result in lower closing forces which are not always acceptable in
closing and latching a door depending on field conditions such as weight of door, hinge
conditions, and or stack pressure.
ŸAn auxiliary door stop, by others, is strongly recommended to avoid damage to the
door closer and adjacent property.
ŸDoors should be hung on ball bearing or anti-friction hinges/pivots.
ŸDoor closer must not be installed on the exterior side of a door located in an exterior
wall of a building.
ŸADA compliant closer.

main arm positioned 90° to frame face. Secure to pinion with arm
screw provided.
8. Pre-load closer unit:
ŸRemove rod screw from adjusting rod. Insert adjusting rod into
rectangular tube of main arm assembly (open door slightly if
needed).
ŸWith door in closed position, rotate main arm until adjusting rod is
90° with respect to door face as shown below (Figure 15.3).
ŸRe-install adjusting rod screw and tighten to maintain closer pre-
load.
Top Jamb Arm Installation Sequence
1. Remove existing LCN arm assembly, closer body and
supporting mounting hardware. If existing drop plate is
present, replace with Norton drop plate part number
9540-18TJ. See page 3, figure 3.2 of this instruction.
NOTE: The existing LCN drop plate must be replaced with
the proper Norton drop plate for the 9540 to perform
correctly.
2. Inspect existing mounting holes for damage. Consult
templates listed below to confirm existing holes are located in
the proper position:
Page 13: 9540 Top Jamb Arm Mount with 9540-18TJ drop
plate (Min. 1-3/4" frame face application)
Page 14: 9540 Top Jamb Arm Mount (3-1/2" frame face
application)
Improperly templated door or frame may affect door
closer performance.
3. IMPORTANT: Using template on Page 14, locate and prepare
two (2) additional holes for #12 screws for closer mounting
plate. Screws will be located under the spring adjust end of
closer when installed. See fastener chart page 4.
(If installing closer body on Norton’s Drop Plate page 13,
these additional holes are already present on drop plate)
4. Secure drop plate (if required) and/or closer mounting plate to
face of frame with hardware provided.
Note: See templates on page 13 and 14 for proper
orientation of these plates in both Left Hand and Right
Hand applications.
5. Fasten the closer body with spring adjust end TOWARD hinge
edge of door and valve oriented as stated below to mounting
plate with hardware provided (Figure 15.1).
Right hand door: Valves facing DOWN.
Left hand door: Valves facing UP.
See templates on page 13 or 14 for illustrations of closer
orientation.
6. Fasten arm shoe of the adjusting rod assembly to door face
with hardware provided. Fasten with pivot point of shoe away
from hinge. For additional 15% increase in closing force,
position arm shoe with pivot point towards hinge edge of door
as shown below. See figure 15.1 below; illustration shows left
hand door. 9. Closer Adjustments: See page 16 for more information.
A) Adjust closing force using the spring adjust screw.
Rotate screw clockwise (CW) to increase force.
Rotate screw counter-clockwise (CCW) to decrease closing
force. Use hex wrench provided.
B) Adjust closing speed and latching speed of door using
valves identified (Figure 16.1).
Rotate valve clockwise (CW) to decrease speed.
Rotate valve counter-clockwise (CCW) to increase door
closing speed.
C) Adjust backcheck intensity.
Rotate (CW) to increase backcheck intensity.
Rotate (CCW) to de-crease backcheck intensity.
D) Delayed Action: (If equipped)
Rotate valve (CW) to increase close delay time.
