Preliminary Mounting and Hole
Layout - No Power & USB
Note: Review space-planning layout
provided to identify which uprights
are to be equipped with tablet arms
and/or aisle lights (Figure 4). Small
tablet arm uprights have two holes
through the top of the front upright
tube to allow for tablet mounting
(Figure 8). Large tablet arm uprights
have a pivot mount bracket between
the top of the uprights (Figure 5).
1. Follow the space-planning layout
and stage the uprights by the correct
type or option.
Caution:
Assembly problems, product failure
and personal injury may result if
uprights are not properly spaced.
Note: On radiused installations, the
front tubes of the upright are shifted
closer together. Rear tubes always
remain at the appropriate dimension
matching the seat size: 19", 20", 21",
22", 23" or 24" (Detail A, “Radius
Chart” and “Tolerances for Mounting
Uprights”).
2. Carefully locate the upright mounting
holes and the appropriate floor
anchors as specified in the
space-planning layout provided.
Study “Detail A” the guidelines in the
“Radius Chart” and “Tolerances for
Mounting Uprights.”
Note: Warranty null and void if
KI Concerto Seating product line
is installed on flooring not meeting
minimum structural requirements
stated above.

Preliminary Mounting and Hole
Layout - with Power & USB
1. Follow the space-planning layout
provided and stage the uprights in
position with the specified right,
left or no-tablet option (Figure 1),
as well as by indicated electrical
circuit number and/or aisle light
option. Each powered upright
comes with a power & USB
receptacle box labeled “1”, “2”, or
“3” (Figure 1). All upright locations
designated “FL” (full-length
side-cover upright) will require a
bottom side cover bracket
(Figure 1). A side cover bracket
is also required at power infeed
locations “P” (Figure 1). A data
bracket is required at data infeed
locations “D” (Figure 1). The data
infeed side cover is full length with
a protrusion at the bottom where
the data wires enter the cover
(Figure 5). Half-height side covers
may be used on uprights where
no power is run up from the floor
(Figure 5). Half-height side cover
locations require no mounting
2. Carefully locate the upright
mounting holes and the appropriate
floor anchors as specified in
the space-planning layout
provided. Study “Detail A” and the
guidelines in the “Radius Chart”
and “Tolerances for Mounting
Uprights”.
3. Route the power infeed to the
correct location according to the
space-planning layout provided.
The power infeed wires must not
be connected to the power source
at this time.

Tolerances for Mounting Uprights
The following tolerances apply to
standard, floor-mounted Concerto.
They are applied to the
center-to-center dimensions of the
uprights, e.g. a 22" seat must maintain
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.

Assembly Instructions
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.
