an upright spacing of 2113/16" to
22 3/16" between the centerlines of the
rear upright tubes. See above “Radius
chart” text in reference to a radius
which is 40' or less. Note that these
dimensions must be maintained at each
seat. Attempting to rob from an adjacent
seat may only move the problem down
the row.

Upright Installation - Standard
Concerto Seating
1. Begin installing the uprights to the
floor by aligning the holes in the
upright foot with the floor anchors.
Insert appropriate fasteners with flat
washers through to the floor. Do
not tighten any uprights down
at this time. Leave fastener loose
with head approximately 1/16" from
contacting the foot of the upright
(Figure 1).
Upright Installation - Concerto
Seating with Power & USB
Note: For the following steps,
refer to the space-planning layout to
determine which uprights will have
full-height side covers. The uprights
at power infeed locations require
these side covers, which must use
the appropriate bottom side cover
bracket. Row ends may also have
full-length covers specified.
1. Begin installing uprights to the floor
by placing the appropriate bottom
side cover bracket over the mounting
holes in the upright foot. Orient
bottom side cover bracket so wire
routing hole is facing in toward the
seat on end-of-run uprights. Align
the holes in the upright foot (and
bracket if applicable) with the floor
anchors. Insert fasteners with flat
washers, through to the floor. Do not
tighten any uprights down at this
time. Leave fastener head loose with
approximately 1/16" from contacting
the foot of the upright (Figure 1).
2. At locations specified for
full-height side covers, use a bracket
locating guide to center the bottom
side cover bracket both front-to-back
and side-to-side. Orient the locator
hole in the guide to the front of the
upright when centering. Tighten
the fasteners, securing the brackets
and uprights to the floor. Only
tighten full-height side-cover
uprights at this time. The other
uprights must only be tightened after
installation of seats.

Back Attachment
1. Follow the Concerto
space-planning layout and stage the
backs at their installation location by
specified size (19", 20", 21", 22", 23"
or 24"). Back spacers are riveted to
the sides of the mounting brackets
on 20", 22" and 24" backs.
Note: For the following procedure,
19", 21" and 23" backs will require
use of the shorter 1/4-20 x 3/4" T-30
Torx screws (no spacers). The 20",
22" and 24" backs will require the
longer 1/4-20 x 1 1/4" T-30 Torx
screws.
2. Install either the 1/4-20 x 3/4" or
the 1/4-20 x 1 1/4" T-30 Torx screw
into the lower back mounting hole
on both uprights. For 19", 21" and
23" units, leave a minimum of 3/8"
of threads exposed when using the
3/4" screws; and for 20", 22" and
24" units (with spacers), leave a
minimum of 7/8" of threads exposed
when using the 1 1/4" screws
(Figure 2).
3. Hold the back at a 30° angle behind
the uprights. Hook the mounting
tabs on each side of the back onto
the lower 1/4-20 Torx screws which
were installed in the previous step.
Rotate the backrest forward to line
up with one of the three top holes
specified to achieve the appropriate
back angle. Each hole marks a
4° increment. Unless otherwise
specified, use the center hole. On
20", 22" and 24" units, the spacers
may be repositioned on the mounting
brackets to achieve a different
angle. Remove the spacer rivet and
reposition the spacer to line up with
one of the other two upper mounting
holes on the mounting bracket. Use
the 1/4-20 x 1 1/4" T-30 Torx screw
to help keep the spacer aligned with
the bracket. The backrest will fit
snugly between the uprights and may
need additional inward pressure on
the mounting brackets to squeeze
between the uprights (Figure 2).
Note: The rivets are used to keep
the holes aligned at assembly, and
the back panel properly connected to
the back board. Do not separate the
back panel from the back board when
removing the rivets. Maintain hole
alignment for assembly.
4. Install and tighten the appropriate
1/4-20 Torx screws in the top of both
sides of the unit. Tighten the screws
in the lower holes (Figure 2).
5. Do not tighten any fasteners to the
floor at this time.

Assembly Instructions
Electrical Distribution Installation
Note: Follow the space-planning
layout provided (also reference
Power Infeed examples on page 15)
to stage electrical components as
specified. The power & USB module
on each powered upright will have
a length of flexible conduit with a
coneector end on it. At power infeed
location(s), an 8-wire power infeed
harness is used to begin distribution
of the power. A 45", 48" or 51"
8-wire span connector is run to every
other seat, passing power to each
individual seating location
(Figure 3). A 24" span connector is
used with a mid-row power infeed
and at the end of a row with an odd
number of seating locations.
1. Check to be certain that each upright
is installed with the correct electrical
circuit designation, as specified in
the space-planning layout.
2. At the power infeed location, connect
both power & USB module connector
ends into quad block #1 (Figure 3).
Do not connect the 8-wire exposed
end of the power infeed harness to a
power source at this time (Figure 3).
3. Plug the connector ends of the span
connectors and power infeed into the
remaining locations in quad block #1.
Route the opposite connector end of
the span connectors between the next
two sets of leg uprights and connect
it to quad block #2. Also connect the
remaining power & USB connector to
quad block #2 as illustrated
(Figure 3.)
Note: Figure 3 illustrates a
three-place unit where one 8-wire
span connector is used and is
the end of the power run with a
quad block (#2). When power is to
continue on, as with four or more
seats, a power & USB connector end
and another distribution harness
would also plug into the quad
block (#2). (Reference power infeed
examples on pace 15).

Large Tablet Arm and Full-Height
Side Cover Installation
Note: It is important that tablet arm
side covers and the large tablet arms
are installed before any other side
covers. Large tablet arm side covers
can be right-hand or left-hand
and full-height or half-height.
For installation of power infeed
side covers see “Power Infeed
Installation.” The instructions and
Figure 5 depict a left-hand end
tablet arm, full-height option. Your
configuration may vary.
1. Carefully maneuver the tablet arm
side cover (left-hand end shown)
against the upright to align the upper
and lower mounting holes with
the holes in the top of the upright
and the bottom side cover bracket.
Secure the cover to the upright with
four #8 x 3/8" Torx screws (Figure 5).
Note: When a tablet arm is installed
to an upright without a tablet arm
side cover, a nylon washer must
be installed between the tablet
mechanism and the pivot mount
bracket per step 2 below.
2. Insert the 3/8-24 x 1.618" hex washer
head Matpoint bolt through the tablet
arm mechanism. If a tablet arm side
cover is not to be installed to the
tablet arm upright, place a nylon
washer onto the 3/8-24 hex washer
head bolt at this time (Figure 5).
3. To avoid cross-threading and
jamming of mounting bolts, do not
use impact drivers to install
tablet hardware. Rest the tablet
mechanism onto the armcap and
thread the 3/8-24 hex washer head
bolt into the tablet arm side cover
pivot mount bracket on the upright.
Tighten the 3/8-24 hex washer head
bolt to 10 inch pounds of torque.
Thread a 3/8" jam nut onto the cap
hex washer bolt behind the pivot
mount bracket. Holding the hex
washer bolt in place with a 9/16"
wrench on the bolt and nut, tighten
the 3/8" jam nut behind the pivot
mount bracket to 450 inch pounds.
Hold the nut tight and back out the
to 500 inch pounds of torque. The
large tablet arm must rotate down
smoothly under its own weight
(Figure 5).
4. The full-height side cover may now
be installed opposite the tablet arm
full-height side cover. Carefully
maneuver the side cover against
the upright to align the mounting
holes. Secure the cover to the upright
with four #8 x 3/8" Torx self-tapping
screws (Figure 5).
5. Continue with the installation of all
large tablet arm side covers and
tablet arms (Figure 5).

Power Infeed Installation
1. Begin installation by making sure
that a bottom side cover bracket has
been installed and tightened correctly
over the foot of the upright. Orient
the power infeed side cover into
position against the upright and the
bottom side cover bracket. Secure
the power infeed side cover to the
bottom bracket only with two
#8 x 3/8" Torx self-tapping screws.
The top screws may be installed
only if no large tablet arm is to be
attached to the upright. The top two
screws must not secure the power
infeed side cover at this time to allow
for access to install the large tablet
arm (Figure 6).
Note: The power infeeds are to be
connected to the power source by
a qualified electrician who must
also check the electrical integrity
of the finished system (see wiring
schematic, page 16). The steps
below are intended as a guideline for
the 90° metal installation.
2. Remove the locking nut from the
threaded end of the 90° metal
connector and take off the back
for ease in routing power wires.
Place the threaded end of the metal
connector through the hole in the
bottom side cover bracket and the
attached power infeed side cover.
Thread a 1/2" rigid straight coupler
onto the connector, over the power
infeed side cover. Route the exposed
8-wires, of the power infeed harness,
through the 90° metal connector and
1/2" rigid straight coupler. Pull the
wires tight from the elbow side, to
compress the flexible conduit to its
required length. Replace the back of
the 90° metal connector and secure
the flexible conduit of the power
infeed harness into the connector
(Figure 6).
3. Slide the liquid-tight connector onto
the 8-wires and connect it to the
1/2" rigid straight coupler. Slide the
liquid-tight conduit over the 8-wires
and connect it to the liquid-tight
connector. Finally, the liquid-tight
conduit may be cut to the appropriate
size, fastened to the junction box
and the 8-wires may be connected to
the power source (junction box not
provided) (Figure 6).
4. For a power infeed upright
requiring a large tablet arm, refer to
“Large Tablet Arm and Side Cover
Installation” steps 2, 3 and 4
(page 8). For a no-tablet full-height
side cover, skip to step 4 in the same
section.
5. Secure the top of the power infeed
side cover with two #8 x 3/8" Torx
screws at this time (Figure 6).

ADA Upright with Flip-Arm Cap
1. ADA uprights are to receive an "ADA
sticker" to designate upright as an
ADA upright. The sticker may be
placed onto either the arm cap or the
support brace as shown (Figure 9).
The sticker should face outward to
the aisle so it can be easily visible.
Note: A 1/4-20 x 3/4" screw (arm
adjust screw) is located on the
underside of the flip-arm cap. The
screw can be turned inward or
outward slightly to adjust the angle
of the arm to be level (Detail B).
Small Tablet Arm - Standard
Concerto
Small tablet arms are not available with
power & data.
1. Stage the product by tablet arm type
to aid product installation.
2. Hold unit as shown. Align holes of
tablet arm mounting bracket to holes
in the upright (Figure 10).
3. Install 1/4-20 x 1 3/4" hex head cap
screws through the backing plate and
into the tablet arm mounting bracket.
Screws should only be started in the
mounting plate (Figure 10).
4. Tighten top screw first to draw the
mounting bracket into the hole. A
portion of the tablet arm mounting
plate fits tightly inside the large
hole in the upright, requiring the
top screw to be tightened first. A
ratcheting box end wrench with
a small head works best. Tighten
bottom cap screw next (Figure 10).
5. Check tablet to assure it is seated
properly to the tube and the
mounting bracket fits flush to the
upright.
6. Check tablet for operation. Tablet
should slide up freely, rotate over
and stop. Rotate tablet back and slide
it down to its resting position.
7. If there is any interference between
seat and tablet, check to make sure
proper seat model was installed. If
so, you may adjust the centering of
the seat slightly to gain clearance
between seat and tablet.

Power Infeed - Power & USB
The harness with single modular
connector at one end and exposed wires
at the other originates from the seat
wireway, routes into the end upright
between an end side cover and power
infeed side cover, goes through a 90°
metal connector inside the covers and
out through a 1/2" rigid straight coupler
at the left-hand, exterior of the power
infeed side cover (when seated). A 24"
length of 1/2" liquid-tight conduit is
supplied (to be cut to size) to house the
wires and connect between the rigid
straight coupler and the building source
power junction box on the floor, under
the seat. The building source power
junction box must be located under the
end seat, ideally 10" to 16" from the
end upright, and 2" to 4" from the
front-to-back centerline of the
upright base.
