Installation Instructions
The installation of the CSW75 system requires a working
knowledge and experience in the use of tools, equipment,
and methods necessary for the installation of aluminum
doors, storefronts, and/or partitions. This practice
assumes a familiarity with preparing a proper and
structurally sound opening, proper anchorage and
assumes an understanding of the fundamentals of
building construction that affect the installation of folding
center pivot frameless systems. A crew of at least 2
persons is needed. These systems can be heavy. Use safe
lifting techniques to avoid injury and product damage.
Highly recommended is using an independent NanaWall
Certified Installer, if available, or, at least, an installer
who has some experience in installing NanaWall systems.
IMPORTANT: READ COMPLETE INSTRUCTIONS
BEFORE BEGINNING INSTALLATION. INSTALL AS
RECOMMENDED; OTHERWISE, THE UNIT MAY
NOT FUNCTION PROPERLY AND ANY WARRANTY,
WRITTEN OR IMPLIED, WILL BE VOID.
CAUTION:
As regulations governing the use of glazed windows,
doors, storefronts,and/or partitions vary widely, it is the
responsibility of the building owner, architect, contractor,
or installer to insure that products selected conform to all
applicable codes and regulations, including federal, state
and local. Nana Wall Systems, Inc. can assume no
obligation or responsibility whatsoever for failure of the
building owner, architect, contractor,or installer to
comply with all applicable laws and ordinances and
safety and building codes.
Please pay special attention to the thickness of glass.
The NanaWall glass thickness for the panels is based
on the Glass Association of North America (GANA)
recommended minimum glass thickness for fully
tempered Interior butt glazed fixed glass panels.
The CSW75 system is shipped with all necessary
components. However, not included are screws, bolts,
shims, etc. to anchor the unit to the opening. The frame
is shipped knocked down and needs to be assembled.
Panels are usually pre-assembled with glass, ready to be
attached to the installed frame. In most cases, all rollers,
pivots, and lockings are pre-attached to the panels.
DESCRIPTION OF SUPPLIED PARTS
First look for an envelope in the shipment, which contains
drawings of the elevation, the layout of the unit and an
Installation Manual. This information together with the
Custom Product Drawings provided by NanaWall at the
time of order will be needed for a successful installation.
As there is no “standard” configuration for CSW75 units,
see Diagram 1 which shows the elevation and layout
of a 5 panel unit to illustrate the installation process.
Some items may not be applicable for your unit. Inspect
the custom product drawing, indicating size, configuration
and labeling of the unit ordered.
Check all parts carefully before assembly. Depending on
the unit ordered, some of these parts may already be pre-
installed on the panels. Check that the sizes of the frame
components and panels match with what was ordered.
The elevation drawing shows the sequence and number
of panels, which depends on the model ordered.
The drawing is always viewed from the outside,
but the locking shown is what is on the inside.
The panels are usually pre-assembled with one upper
carrier for each folding panel and with one specified
locking. The sequence of labeling of panels starts from
the left looking from outside with the left most panel
labeled Panel #1.

Other components include:
• Push/pull handles, other handles,or other hardware,
as ordered may not be pre-attached to the panels
and will be in the hardware box or shipped
separately.
• The layout drawing of your unit shows the upper
track components consisting of the head track in the
opening, how they are labeled and how they have to
be connected. The joints for the transitions are
indicated and necessary connectors for connecting
different upper track pieces are provided.
• The location of the removable head track (RHT)
portion to insert the rollers on panels is indicated on
the layout drawing.
• The overhead door closer will be in the hardware box
and is not pre-attached to the top rail and has to be
installed in the field after final adjustments were
made.
• Specified floor sockets, pivot points,and floor closers.
HANDLING OF COMPONENTS
1. Upon receipt, inspect the shipment to ensure it is in
good condition.
2. Make sure that all components and hardware, which
might be shipped separately do not get lost.
3. Store in a clean and dry location and protect against
defacement or damage, especially to the edges of
panels.
PREPARATION OF THE OPENING AND SUPPORT
STRUCTURE ABOVE
Make rough opening width at least 1/2"wider than the
outside unit frame width and rough opening height about
3/4"taller than the total unit height depending on how
level the support structure above is. See Sheet 2 of the
Installation Manual. It is important that the opening be
the correct size.
Product performance that includes operation, depends
on having the gap between the bottom of the panel and
the top of the finish floor be maintained at 7 mm (1/4")
and also the gap between the top of the panel and the
bottom of the head track to be maintained at a nominal
gap of 23 mm (7/8"). The running carriages can be
adjusted, if needed. The finish floor needs to be
absolutely level across the length of the opening.
The track length and layout have been supplied based on
the configuration and sizes chosen and approved. Please
refer to the layout drawing of your particular CSW75
project, to determine the correct location of the support
structure (by others) and for the support of the head
track in the plane of the opening. It is important that the
system is properly supported at the top.
IMPORTANT: Any application should take into
consideration the following:
1. As the CSW75 system is a top-hung system, it is
essential that a proper substrate with the proper
size and thickness be used for the support structure
above in order to support the head track in the
opening.
2. The structural integrity of the support structure is
critical for proper operation. Vertical deflection of
the header under full live and dead loads should be
the lesser of L/720th of the span and 1/4". It should
be designed to accommodate the total weight of the

NANAWALL CSW75 OWNER’S MANUAL
5
panels (i.e. system weight with 12 mm (1/2") tempered
glass app. 8lb/ft²) in the opening and in the stacking
area (unit in open position).
3.Structural support for lateral loads (both windload, if
any, and other lateral force) must also be provided.
4. The rough opening should be reasonably level,
plumb and square at all points. There should be no
unevenness or bowing. Make sure that the header is
not tilted or twisted. There should be no bumps on
the floor. The sides should be in the same vertical
plane and not offset of each other. A transit/laser
and other similar precise measuring equipment
should be used. YOU NEED TO ADJUST THE
FLOOR AT THE OPENING TO MAKE IT
ABSOLUTELY LEVEL.
5. See Sheet 10 – 14 of the Installation Manual for
drawings of bottom door closer, pivot point and floor
sockets to determine sizes of holes or slots that need
to be made in the finish floor and substrate below. As
there are different size floor sockets available, please
verify the type of sockets for this order. If planning to
cut into a post tensioned concrete for bottom door
closers, pivot points and sockets, a structural
engineer and architect has to be consulted.
6. The finish floor will need to be perfectly level with no
unevenness in the opening area. For the installation
of bottom door closers, pivot points and floor sockets
in concrete slabs and wood, the substrate should be a
minimum of 4"thick, these components should be
fully embedded into the concrete or wood and the
clear edge distance in concrete or wood should be a
minimum of 2".
7. Floor sockets, pivot points,and bottom door closers
will need to be installed at precise locations after all
panels are installed and final adjustments are made.
8. For installations into heavy gage, all metal studs must
have wood backing.
9. For better performance it is strongly recommended
that all dead loads such as upper levels, roof, etc.
be constructed and reasonable time for it has been
allowed to settle before a unit is installed.
To avoid future problems, do not install your unit until
the rough opening and the support structure have been
correctly prepared.

A. FRAME ASSEMBLY AND INSTALLATION
Since there can be an infinite number of variations and
configurations, it is not possible to have step by step
specific instructions that will apply to all units installed.
Below are general instructions that focus on the
installation of a 5 panel unit as shown in Diagram 1. This
may not exactly apply to your particular unit. Please refer
to the Custom Product Drawings for your specific project.
The key to having a properly installed and
operating CSW75 system is to install a perfectly
level upper track at the correct height from the
finish floor level.
Step A1
Look for the labels on the dierent upper track segments
and set them on the floor as per the layout of the head
track on the custom product drawings.
Step A2
Attach as many of the upper track pieces together that
could be supported and installed easily as one piece. Use
the connectors and set screws provided. See Sheet 4 of
the Installation Manual. Make sure that the transitions
between the track segments are perfectly aligned and
smooth.
Step A3
The roller access head track section is a removable
section in the head track (RHT). This section will need to
be later removed when the panels are installed.
Step A4
The head track is pre-drilled in the factory with anchorage
holes at spacing’s of about 10"(250 mm) for 5/16"(8 mm)
diameter screws or bolts. See Sheet 3 of the Installation
Manual.
The correct fastener spacing in the support structure
within the opening depends on substrate material, design
windload pressures (if exterior) of project, panel height
and other requirements of the project. All anchoring
details and requirements should be determined and
verified by the project structural engineer. Please pre-
drill any additional anchorage holes as needed.
Use appropriate anchorage devices depending on the
project lateral load requirements and adjacent substrate
material and construction. If the factory pre-drilled holes
are sufficient, then 8 mm (5/16") diameter screws can be
used. Make sure they are corrosion resistant and that the
screw head is small enough to fit inside the slot in the
middle of the head track, otherwise it will interfere with
the running carriages. Anchorage devices should
penetrate (embedment) or hold sufficiently to the
opening to withstand necessary lateral loading. Attention
should also be made to the minimum edge distance that
must be maintained for different substrates. Generally,
for wood frame, minimum embedment is 2 1/2"and
minimum edge distance is 3/4", for concrete minimum
embedment is 1 1/4"min. and minimum edge distance is
2".
Step A5
For all anchorage options, set the assembled part of the
upper track into the rough opening at the proper
position relative to the support structure and the finish
floor.
Step A6
Support the upper track temporarily in a safe manner.
Step A7
Place hard plastic horseshoe shims tightly at every fixing
point between the upper track and the header. Anchor
the head track with appropriate screws through the pre-
drilled holes or as needed. See Sheet 5 of the Installation
Manual.

NANAWALL CSW75 OWNER’S MANUAL
7
IMPORTANT: ADJUST EACH ANCHORAGE
POINT AS NEEDED TO MAKE THE UPPER TRACK
ABSOLUTELY LEVEL AND PLUMB. USE A
TRANSITLASER AND OTHER SIMILAR PRECISE
MEASURING EQUIPMENT TO MAKE THESE
DETERMINATIONS. MAKE SURE NO SHIMS
ARE FORCED TO ENSURE THAT THE UPPER
TRACK IS NOT BOWED OR TILTED.
Upper track segments must be joined such that they
are even, tight,and aligned perfectly. Otherwise, the
running carriages may wear out prematurely, which
will then not be covered by warranty. Placing shims at
the meeting points of track segments may help in
keeping the transition points even, even though there
may not be anchorage holes at this point. See Sheet 5
of the Installation Manual.
Make sure that all surfaces of the upper track are clean
and free of any debris, especially cuttings from drilled
holes.
Do not attach anything from the side against the head
track.
Do not drill any holes for sockets, pivot points,
and floor closers, yet!
B. PANEL INSTALLATION FOR
ALL FOLDING PANELS
As there can be many possible configurations, panel
installation will vary with each unit. Below are guidelines
for a 5 panel unit shown in Diagram 1. Determine the
interior/exterior side of the panels and install them such
that they are facing the correct direction. Please also refer
to E. PANEL INSTALLATION OF A SINGLE/DOUBLE
ACTION END PANEL after following the instructions in C
and D.
Step B1
Check all the carriers on all the folding panels. Make sure
all the locking nuts are securely tight. Do not make any
adjustments on the carriers, yet.
Step B2
Before inserting the panels, remove the roller access
head track section (RHT). See Step 0 on Sheet 6 of the
Installation Manual. Hang 1st folding panel (Panel #4) by
inserting the center carrier of this panel into the opening
in the head track. Secure panel before you proceed with
2nd panel (Panel #3). Then hang 2nd panel the same way
and line up the hinges with the 1st panel. Add the hinge
pins to the hinges at the bottom and top. Secure hinge
pin with the set screws from the side. Tighten set screws
and then back it o a 1/4 turn. Afterwards add cover on
top of the hinge pin.
Step B3
Install additional folding panels in the same manner.
Step B4
After you inserted all folding panels, secure them in the
opening. Before you reinstall the removable head track,
take the top pivot point for the half size panel (Panel #1)
from the hardware box and slide it inside the top track.
Now put the RHT back on and make sure that the joints
are aligned perfectly. See also Sheet 7 of the Installation
Manual.
Step B5
To install the half panel at the side (Panel #1), slide the
top pivot point over to the side of the RHT. Check that
the dimension from the edge of the top track to the
center point of the axle is 44 mm (1 3/4"). Fix the pivot
point in position. Line up the pivot point at the bottom
with the pivot point at the top by using a transit/laser or
other similar precise measuring equipment and mark the
bottom point on the chalk line.

NANAWALL CSW75 OWNER’S MANUAL
8
Now drill the appropriate size hole for the pivot point.
If concrete, use a diamond core drill bit with the proper
diameter size.
Step B6
Install the “half” panel by setting it on top of the bottom
pivot point first and then attach it to the top pivot point
by pushing up the bolt of the top pivot point and screwing
it onto the shoe inside the top clamping profile. Before
you tighten the bolt and nut, measure the horizontal
reveal at the bottom and top and keep it consistent with
the rest of the panels.
Step B7
Now you can attach the half panel (Panel #1) to the
adjacent folding panel (Panel #2) by adding the hinge pin
as described under Step B2.
IMPORTANT: DO NOT INSTALL ANY SINGLE
DOUBLE ACTION END PANELS, YET.
Do not drill any additional holes for sockets,
pivot points and floor closers, yet!
C. GAPS AND ADJUSTMENT
After inserting all the folding panels, operate the unit
and check the vertical and horizontal reveals. Check if
all panels are vertically straight and if you left enough
space for the single/double action end panel. See Sheet
8 of the Installation Manual. Between the folding panels
there should be an even gap of 2 mm (about 1/16"). Any
problems may be due to the head track not being
absolutely level.
The horizontal spacing between the bottom of a panel
and finish floor should be 7 mm (about 1/4") consistently
across the width of the opening and 23 mm (7/8") at the
top.
If the gaps are not correct, then adjust the upper track
by removing or adding shims above the head track as
needed. The upper track has to be perfectly level.
If there are still issues on the gap between panels and
the gap at the bottom not being correct, then the
running carriages can be adjusted. The carriages on the
panels are normally set from the factory to have a gap
of 23 mm (7/8") from the bottom of the head track to the
top of the top rail.
To adjust the height of the panels, use a 19 mm open jaw
wrench from the side. Clamp on the flat part of the bolt
that is located near the bottom of the roller with the
11 mm open jaw wrench and adjust the height.
Counter-clockwise rotation = less floor clearance;
clockwise rotation = more floor clearance. See Sheet 8 of
the Installation Manual.
After final adjustments make sure to really tighten
down the nut.
After you adjusted all folding panels, measure the width
for the single action end panel (non-sliding) again
and make sure it fits into the opening.
Now you can start drilling holes for sockets!
Do not install the single/double action end
panel, yet!
D. SOCKETS
Holes in the floor for the sockets have to be made at
exact precise spots. There is no second chance if the hole
location is o. See Sheet 9 of the Installation Manual.
With a laser, find the center line of the head track
on the floor along the length of the opening, and mark
it with a chalk line. Close the unit such that the panels
are in the correct closed positions. Start with the panel

NANAWALL CSW75 OWNER’S MANUAL
9
on the opposite side of the single/double action end
panel (Panel #2) and add blue masking tape underneath
the approximate location of the locking bolt. Slowly and
carefully engage the locking point until it touches
the tape. The tip of the locking bolts should make
a mark on the blue tape that would be the center point
of the socket hole.
From the custom product drawings and the locking type
on the panels, drill the appropriate size socket hole.
If concrete, use i.e. a diamond core drill bit with the proper
diameter size.
Slide the proper sockets into the holes. If necessary, use
suitable material to fix them in place. Open the unit and
close it again and make sure the locking mechanism
lines up with the floor socket. Please proceed with the
next hole (one hole at a time) and repeat the process
described above for all folding panels.
E. PANEL INSTALLATION FOR SINGLE/
DOUBLE ACTION END PANELS (NON- SLIDING
CENTERED AND OFFSET INCLUDING PIVOT
POINT AND FLOOR CLOSER INSTALLATION
Holes and slots in the floor for the pivot points and floor
closers have to be made at exact precise spots. There is
no second chance if the hole/slot location is o. See Sheet
10-14 of the Installation Manual.
Step E1
Start at the bottom and use the chalk line as a reference
line. Measure the overall width of the panel and compare it
with the dimension on the custom product drawing. To
this dimension add 3/16"(4 mm) at each end to make sure
the correct 3/16"(4 mm) gap between the panels and
between the panel to the wall is maintained.
Then the panel has to fit in the remaining opening.
Step E2
For the center pivot end panel (non-sliding) with pivot
point, the dimension for the center of the pivot axle to the
adjacent edge of the panel (end cap) should be 1
11/16"(43 mm) plus the additional 3/16"(4 mm) for the
gap to the wall. Please check custom product drawing for
wing direction (inside/outside). See Sheet 10 of the
Installation Manual. This means a total of 1 7/8" (47 mm)
to the edge of wall. Mark this dimension on the chalk line.
If concrete, use a diamond core drill bit with 1 1/4"
diameter. Install the pivot point and if necessary, use
suitable material to fix it in place. Then install the top
pivot axle into the top track. Start inserting the upper
flush part into the top track, turn it a 1/4 counter clock
wise, push it up higher and turn it another 1/4 clock wise.
Before you fix the axle with the 2 set screws in place,
please use a transit/laser or other similar precise
measuring equipment to line up the center of the bottom
pivot point with the center of the top axle. See Sheet 11 of
the Installation Manual.
In preparation for the installation of this panel, take o
the end cap and top cover on the inside. Screw the
adjustable bracket onto the threaded bolt of the top axle
and make sure that the set screw at the side is lose. Now
you can install the panel by lifting the pivot axle, that is
installed underneath the bottom of the panel, on top of
the bottom pivot point. Line the top axle with bracket up
with the shoe that is inserted into the top profile and
connect both parts with one another. See Sheet 12 of the
Installation Manual.
Before you finally tighten down all screws, make sure that
all dimensions are set correct, the panel can be opened
and closed with the right clearance and check if the
panel is plumb and level. Then fix all screws in place and
secure the top axle by fixing the set screw from the side.
Afterwards put the top cover with end cap back on.

NANAWALL CSW75 OWNER’S MANUAL
10
Step E3
For the offset pivot end panel (non-sliding) with pivot
point, the dimension for the center of the pivot axle to the
adjacent edge of the wall should be 1/16"(2 mm) and it
should be offset to the chalk line by 2 1/16"(52 mm).
Please check custom product drawing for swing direction
(inside/outside). See Sheet 13 and 14 of the Installation
Manual. Mark this point and if concrete, use a diamond
core drill bit with 1 1/4"diameter. Install the bottom pivot
point and if necessary, use suitable material to fix it in
place. Then install the receiver box for the top axle by
hanging it off on the side of the top track and fix it slightly
with the 2 set screws. Use a transit/laser or other similar
precise measuring equipment to line up the center of the
bottom pivot point with the center of the top receiver box.
The 2 offset pivot brackets are installed on panel #5
already. When you start installing this panel, set the
bottom pivot axle on top of the pivot point and line up the
top bracket with the receiver box at the top. Take the top
axle out of the accessory box and connect the bracket
and the receiver box by sliding it in from underneath. Fix
the top axle with the set screw from the side and add the
cover on top of the hinge pin. Before you finally tighten
down all screws, make sure that all dimensions are set
correct, the panel can be opened and closed with the
right clearance and check if the panel is plumb and level.
Step E4
For the center pivot end panel (non-sliding) with floor
closer, the dimension for the center of the pivot axle of
the floor closer to the adjacent wall should be 2 1/2" (64
mm). Please check custom product drawing for swing
direction (inside/outside). See Sheet 10 of the
Installation Manual. Mark this dimension on the chalk
line. Then mark the dimensions of the box on the floor
and if concrete, cut and chisel out the concrete to recess
the floor closer into the floor.
Make sure that the full underside of the box rests on a
flush and level surface and fix it temporarily into place.
Then install the top pivot axle into the top track. Start
inserting the upper flush part into the top track, turn it
a 1/4 counter clock wise, push it up higher and turn it
another 1/4 clock wise. Before you fix the axle with the
2 set screws in place, please use a transit/laser or other
similar precise measuring equipment to line up the center
of the axle of the floor closer with the center of the top
axle. See Sheet 11 of the Installation Manual.
In preparation for the installation of this panel, take o
the end cap and top cover on the inside. Screw the
adjustable bracket onto the threaded bolt of the top axle
and make sure that the set screw at the side is lose. Now
you can install the panel by lifting the receiver shoe that
is installed underneath the bottom of the panel, on top of
the axle of the floor closer. Line the top axle with bracket
up with the shoe that is inserted into the top profile and
connect both parts with one another. See Sheet 12 of the
Installation Manual.
Before you finally tighten down all screws, make sure that
all dimensions are set correct, the panel can be opened
and closed with the right clearance and check if the
panel is plumb and level. Then fix all screws in place and
secure the top axle by fixing the set screw from the side.
Afterwards put the top cover with end cap back on.
After everything is installed and adjusted including the
floor socket for the locking point of the pivot panel, use
suitable material to fix the floor closer in place.
Step E5
For the offset pivot end panel (non-sliding) with floor
closer, the dimension for the center of the pivot axle of
the floor closer to the chalk line (CL of track) should be 2
1/16"(52 mm). The center point is then offset to the wall
by 1/16"(2 mm). Please check custom product drawing
for swing direction (inside/outside). See Sheet 13 and 14
of the Installation Manual. Mark this dimension on the

NANAWALL CSW75 OWNER’S MANUAL
11
floor. Then mark the dimensions of the box on the floor
too; if concrete, cut and chisel out the concrete to recess
the floor closer into the floor. Position the box at the right
location in relationship to the edge of the wall. Make sure
that the full underside of the box rests on a flush and level
surface and fix it temporarily into place. Then install the
receiver box for the top axle by hanging it o on the side
of the top track and fix it slightly with the 2 set screws.
Use a transit/laser or other similar precise measuring
equipment to line up the center of the bottom axle of the
floor closer with the center of the top receiver box.
The 2 oset pivot brackets are installed on panel #5
already. When you start installing this panel, set the
bottom pivot axle on top of the pivot axle of the floor
closer and line up the top bracket with the receiver box
at the top. Take the top axle out of the accessory box and
connect the bracket and the receiver box by sliding it in
from underneath. Fix the top axle with the set screw from
the side and add the cover with screw. Before you finally
tighten down all screws, make sure that all dimensions are
set correct, the panel can be opened and closed with the
right clearance and check if the panel is plumb and level.
After everything is installed and adjusted including the
floor socket for the locking point of the pivot panel, use
suitable material to finally fix the floor closer in place.
Before you put on the cover for the floor closer, make sure
to measure how much to cut o to make it fit with the
edge of the wall.
F. FINAL STEPS
Step F1
Close and lock all panels into position. For proper
operation, follow the instructions in the Operation section
of this manual. Check that the system operates and
functions properly.
Step F2
Attach handles and other hardware that have not been
pre-attached. Attach the profile cylinder (if any) to
the locking gear by inserting it into the lock hole and
attaching the set screw through the screw hole on the
gear located at the edge of the panel. Cut the set screw,
if needed. See Sheet 14 of the Installation Manual.
Step F3
Correct any problems before you finish the trimming.
Do not attach any trimming directly to the top track.
Be sure that the removable head track piece can be
accessed and removed if needed. The head track should
not be subject to any loads from suspended ceilings, etc.
PROTECTION OF THE UNIT DURING
THE CONSTRUCTION PHASE
It is important that during the construction phase
the unit be kept closed, covered and protected from
damage. During this phase, a unit is often subject to the
most extreme conditions from all types of construction
operations that can permanently damage and destroy
it. A unit can be damaged by cement splatter, tar, paint,
weld splatter, falling objects, construction dust, sand
blasting, etc. All temptations to use the large opening
of an installed system for easy ingress and egress by
tradesmen should be resisted.

Operation And Maintenance
Of Nanawall Products
OPERATION OF A NANAWALL CSW75 – FOLDING
CENTER PIVOT FRAMELESS SYSTEM
For opening and closing the folding center pivot frameless
system, please observe the special notes on the following
pages in as far as they relate to your unit.
When operating the system similar to any other
door, please do not place your fingers between
the panels/pivot points. Be very careful when
you operate the panels and avoid glass to glass
contact between the panels!!
Only properly trained personnel should operate the unit.
No children should operate the unit.
Do not force the system if not operating properly. If you
encounter any difficulties in operating the unit, please
have it inspected by a NanaWall Certified Installer as
soon as possible.
The correct sequence of opening and closing of panels is
dependent on the configuration ordered. Panels must be
opened and closed in the right order in a gentle manner.
Opening and Closing a Unit.
1. If available, please open the single/double action end
panels, first.
2. Disengage all of the locking points on each folding
panel. Operation of each type of lock as follows:
a. Profile Cylinder – turn with key or thumb turn.
b. Quick Release Lock – pull knob and lift up/down.
3. Now you can open the folding panels by slightly
pushing against 2 adjacent panels from the front,
where the hinge part with hinge pin is located in your
direction. The panels fold together and you can push
them gently from the side using both hands.
4. Note that there is a carrier at each upper center of a
folding panel and no guide at the bottom that could
prevent the panels from swaying. Do not move more
than 4 panels at a time.
5. When you have a swing panel attached to a folding
panel with carrier, make sure that you open the swing
panel 180°, first and keep it in this position when you
fold the panels to the side.
6. Do not force. Avoid any pendulum movements,
otherwise the bottom rail could damage the floor.
7. If there are more panels stacking to one side or both
sides (left/right with up to 4 panels), please be sure to
handle the chain of panels with care and fold them to
the correct side.
8. For closing, please proceed in reversed order as
described above. To pull the panels from the stacked
position, you will need to grasp the first panel
by the edges with both hands as high as possible.
Move evenly and keep panels as vertical as possible.
Avoid any pendulum movements.
9. Make sure each folding panel is placed in its proper
position in the opening and engage the locking point
before moving the next panel. Do not place your
fingers between the panels/ pivot points. Do not force
any locking point.
10. For units with multiple panels folding to one side
or both sides (left/right with up to 4 panels), make
sure that each chain of panels is placed in its proper
position in the opening and engage all locking points
before moving the next chain of panels.

RECOMMENDED MAINTENANCE
OF NANAWALL PRODUCTS
Some General Considerations on all Projects:
1. It is important that the product is properly installed.
A poorly installed unit will not function properly. This
will cause more abnormal force or stress on the
components and will lead to premature failure. When
operating the unit, the panels should generally be
able to be moved easily by one person. When moving
across joint locations of head track transitions, there
should be no bumps, otherwise the carriers may
prematurely wear out. All locking points should
engage smoothly. There should be no rubbing on the
floor and no binding. When the unit is closed, the
horizontal reveal between panels and the head track
and between panels and the floor should be
consistent. Please have all problems corrected as
soon as possible by a qualified technician or a
NanaWall Certified Installer.
2. From time to time, due to building movement or
settlement, a unit may need to be adjusted by a
qualified technician or a NanaWall Certified Installer
to compensate for any building change.
3. It is important that a unit is operated properly.
Locking points should be gently opened and closed
and not forced. Panels should be opened and closed
in the proper manner and sequence. See the
Operation section for proper operation.
4. Periodically check for worn or damaged components
and replace as soon as possible. A unit with
nonworking components will subject the other
components to increased stress and lead to
premature failure. A unit with worn or damaged
components will compromise the performance level
expected.
5. Remove debris and other foreign bodies which
have accumulated in the head track and sockets
immediately to prevent damaging the carriers
and maintain proper locking. Clean and lubricate all
movable parts and components as needed.
Check brushes for proper seating and condition.
Remove dust and any deposits from these brushes.
6. The finished aluminum or stainless steel surface
needs periodic cleaning and maintenance. Its
appearance may be marred by harsh chemicals,
abuse or neglect. Frequency of cleaning depends
on exposure and needs. For aluminum surfaces,
generally warm soapy water should be suicient.
Stubborn stains and deposits may be removed
with mineral spirits. Heavier accumulations can be
removed with a mild solution of household detergent.
For all surfaces, aggressive alkaline or acid cleaners
should not be used. Excessive abrasive rubbing
should be avoided. Sealants and weather stripping
may be aected by strong organic solvents.
7. All hardware, hinges and handles should
be periodically cleaned with a soft cloth
and mild cleanser. Excessive abrasive rubbing
should be avoided.
8. It is highly recommended that a maintenance/
service contract be entered with a NanaWall certified
installer, who can clean, lubricate and inspect
on a periodic basis.

MAINTENANCE CHECK LIST
Following recommended check list of Maintenance Notes
to be carried out on a regular basis by a maintenance
person:
a. Clean upper track
b. Check height adjustment and setting
of each panel
c. Check if all panel end caps are in place
and fixed
d. Check if all carriages can be moved easily
e. Check if counter nuts on carriages are
adequately fastened
f. Check if hinges can be moved easily; lubricate
if necessary
g. Check if pin carriers in pivot panels are
in the right position
h. Ensure that the lower locks can be moved
easily; lubricate if necessary
i. Check if floor sockets, pivot points and door
closers are adequately fastened to the floor
j. Remove any dirt from the floor sockets, pivot
points and bottom door closers
k. Ensure that any lock and profile cylinder can be
moved easily
GLASS INSTALLATION AND GLAZING
This section applies only if you need to install glass for
any reason. Proper glass installation is critical, as, with the
NanaWall Folding Center Pivot Frameless System, glass is
a structural part of the panel.
Glass, with appropriate dimensions, thickness and
specifications will be needed. Depending on the model,
widths of frameless all glass panels may not be equal. Ask
NanaWall for the glass dimensions. Please note that glass
is required to be safety glass – either fully tempered or
laminated as specified for a particular order. Check with
all applicable codes and regulations.
Glass shall meet the current requirements of ASTM C
1306 “Standard Specifications for Flat Glass” for quality,
thickness and dimensional tolerances. Tempered float
glass shall meet the current requirements of ASTM C
1048 “Standard Specifications for Heat-Treated Flat
Glass - Kind HS, Kind FT Coated and Uncoated Glass.”
All tempered glass shall have a permanent logo, which
signifies Safety Commission 16 CFR-1201 and the safety
glass test requirements of ANSI Z 97.1 (current editions)
or other equivalent safety standards.
Follow all proper applicable glass installation and glazing
techniques as recommended in the Flat Glass Marketing
Association (FGMA) “Glazing Manual” and “Sealant
Manual”. Always use suction cups to shift glass within an
opening. The panels would need to be removed from the
opening to install the glass. Panels can be laid flat on
sawhorses.
Please contact NanaWall before you replace a glass
pane in order to get the right material and instructions
to glaze the panel!
