Installation Instructions
The installation of the HSW75 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 structural support for
stacking bays and proper anchorage and assumes an
understanding of the fundamentals of building
construction that affect the installation of large horizontal
single track sliding 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 HSW75 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 pre-assembled with glass, ready to be attached
to the installed frame. In most cases, all rollers, pivots,
brushes 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 HSW75 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 pre-assembled with two upper carriers for each
sliding panel and with 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, the stacking route(s) and the stacking
bay(s), how they are labeled and how they have to be
connected. The joints for the segments are indicated
and necessary connectors for connecting dierent
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 and the conversion box of
single/double action sliding panels are pre-attached
to the top rail, but the locking receiver to be installed
on the side of the head track will be in the hardware
box.
• To prevent the panels from coming o the top track,
stoppers have to be installed at the ends.
• Specified floor sockets, pivot points, pivot boxes and
floor closers
• Crank handle for single/double action sliding panels,
if any.
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 does 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 25 mm (1"). The running carriages can be
adjusted, if needed. The finish floor needs to be
absolutely level across the length of the opening and in
the stacking bay.
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
HSW75 project for the correct location of the support
structure (by others) for the support of the head track
at the opening, stacking route and stacking bay. It is
important that the system is properly supported at the
top and at the proper locations.
IMPORTANT: Any application should take into
consideration the following:
1. As the HSW 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

NANAWALL HSW75 OWNER’S MANUAL
5
above not only as support for the head track in the
opening but support of the head track at all locations
including the stacking bay and stacking route.
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
panels in the opening and in the stacking area.
3. Structural support for lateral loads (both windload, if
any, and other lateral force) must also be provided.
4. A qualified engineer or architect should be used to
determine the proper construction details and
support structure to be used in your particular
application.
5. 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.
6. See Sheet 10 – 15 of the Installation Manual for
drawings of bottom door closer, pivot box, 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 boxes and
sockets, a structural engineer and architect has to be
consulted.
7. The finish floor will need to be perfectly level with no
unevenness - both in the opening area and stacking
area. For the installation of bottom door closers,
pivot boxes 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".
8. Floor sockets, pivot boxes and bottom door closers
will need to be installed at precise locations after all
panels are installed and final adjustments are made.
9. Installations into heavy gage all metal studs must
have wood backing.
10. 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 of
stacking options 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 HSW75 system is to install a perfectly
level upper track at the correct height from
the level finish floor, then after the panels are
installed, placing sockets in the floor such that
they are precisely aligned to the panel locking.
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.
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 correct angles between segments are maintained
and 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.
The spacing of anchorage devices in the stacking bay
should be every 4"and in the stacking route every about
10"(250 mm). 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.

NANAWALL HSW75 OWNER’S MANUAL
7
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.
Step A8
Assemble and install other segments of the upper track
in a similar manner. Make certain that the angles between
different upper track components are exact. If the
stacking bay has parallel legs, make sure that the legs are
exactly parallel.
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.
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 segments 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
SLIDING 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 (NON-SLIDING) after following
the instructions in Cand 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, add stoppers at the very ends
of the top track to prevent panels from coming o the
track. See Sheet 8 of the Installation Manual.

NANAWALL HSW75 OWNER’S MANUAL
8
Then remove the roller access head track section (RHT).
See Step 0 on Sheet 6 of the Installation Manual. Hang
sliding panels by inserting the carriers on each panel into
the opening in the head track in the proper sequence.
Make sure that the orientation of the guiding rollers of
the carriers on each panel is on the proper side. See the
custom product drawings for the correct orientation
(straight line with rollers on top of the elevation). See also
Sheet 6 of the Installation Manual.
IMPORTANT: IF THE GUIDING ROLLERS ARE NOT
ORIENTED CORRECTLY, THE PANELS WILL NOT
STACK PROPERLY.
Step B3
Install additional sliding panels, including any single/
double action sliding panels (Panel #3), in the same
manner.
Step B4
After you inserted all sliding panels, reinstall the
removable head track (RHT) and make sure that the
joints are aligned perfectly.
IMPORTANT: DO NOT INSTALL ANY SINGLE
DOUBLE ACTION END PANELS NONSLIDING,
YET.
Do not drill any additional holes for sockets,
pivot points and floor closers, yet!
CAUTION! DO NOT USE THE CRANK HANDLE
TO DISENGAGE THE UPPER ARM OF THE
TOP RAIL OF ANY SINGLE/DOUBLE ACTION
SLIDING PANELS UNTIL ALL THE PANELS
AND LOCKING RECEIVERS OR SOCKETS ARE
INSTALLED AND IN PLACE. THE UPPER ARM
OF THE TOP RAIL HAS TO BE SECURED TO
THE HEAD TRACK VIA THE CONVERSION
BOX AND THE QUICK RELEASE LOCK ON THE
PIVOT SIDE HAS TO BE SECURED TO THE
SOCKET IN THE PIVOT BOX IN THE FLOOR
BEFORE THE SINGLE/DOUBLE ACTION
SLIDING PANEL CAN FUNCTION PROPERLY.
OTHERWISE, IT WILL NOT BE STABLE AND
CAN FALL AND HURT SOMEBODY.
C. GAPS AND ADJUSTMENT
After inserting all the sliding panels, slide them to the
correct closed position and oset them to one another so
that any side protruding locking mechanism is not in the
way. See Sheet 7 of the Installation Manual. Check if all
panels are vertically straight and if you left enough space
for the single action end panel (non-sliding). See Sheet 8
of the Installation Manual. Between panels there should
be an even gap of 4 mm (about 5/32") from top to bottom.
Any problems may be due to the head track not being
absolutely level. A difference of 1/16"or less in the level of
the head track between the two corners of a panel can
cause a 1/4"shift of the panel from the vertical position
enough for a panel not to close properly.
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 panel.
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 25 mm (1")
from the bottom of the head track to the top of the top
rail. See Sheet 7 of the Installation Manual.

NANAWALL HSW75 OWNER’S MANUAL
9
To adjust the height of the panels, remove the end cap
on the side of the carrier of the top rail and loosen the set
screw holding the carriage bolt and the nut using a 22 mm
open jaw wrench. 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. After final adjustments make sure to
really tighten down the nut first and then the set screw
to secure the bolt/axle from turning.
After you adjusted all sliding panels, measure the width
for the single action end panel (non-sliding) again and
make sure it fits into the opening. If necessary use the
stopper in the top track to adjust the dimension. The
stopper on the inside of the top track at the end of the
plain of the opening should be touching the running
carriage and is used as a reference point on that side for
the overall width of the unit.
Now you can start drilling holes for sockets and
pivot boxes! Do not install the single/double
action end panel (non-sliding), yet!
D. SOCKETS AND PIVOT BOX
Holes and slots in the floor for the sockets and pivot
boxes have to be made at exact precise spots. There is no
second chance if the hole/slot location is off. See Sheet 9
and 10 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 by osetting them to one another
so that any side protruding locking mechanism is not in
the way. Make sure the panels are straight and the correct
4 mm gap between panels is maintained. Start with the
panel furthest away from the parking bay and add blue
masking tape underneath the approximate location of
the locking bolts. Slowly and carefully engage the locking
points 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 holes. If
concrete, use a diamond core drill bit with the proper
diameter size. Also for the pivot box chisel out the
appropriate space needed.
Slide the proper sockets and pivot boxes into the holes. If
necessary, use suitable material to fix them in place.
Now you can start drilling holes for sockets,
pivot points and floor closers for the single/
double action end panel (non-sliding)!
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
11-15 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"

NANAWALL HSW75 OWNER’S MANUAL
10
(43 mm) plus the additional 3/16"(4 mm) for the gap to
the wall. See Sheet 11 of the Installation Manual. This
means we have 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 12 of the Installation Manual.
In preparation for the installation of panel #5, take off 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 panel #5 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 13 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.
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 14 and 15 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. 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 7/16"
(62 mm). See Sheet 11 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. 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 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

NANAWALL HSW75 OWNER’S MANUAL
11
of the axle of the floor closer with the center of the top
axle. See Sheet 12 of the Installation Manual.
In preparation for the installation of panel #5, 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 panel #5 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 13 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 14 and 15 of
the Installation Manual. Mark this dimension on the floor.
Then mark the dimensions of the box on the floor, too
and 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 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 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
For single/double action sliding panels, install the
locking receiver on the side of the head track where the
Conversion Box with bolt is located. See Sheet 10 of
Installation Manual and CAUTION in section B above.
Make sure the locking receiver is aligned to the locking
bolt of the Conversion Box and tighten it with 2 sets
crews to the top track. The first step to convert a single/

NANAWALL HSW75 OWNER’S MANUAL
12
double action sliding panel into a single/double action
door is by engaging the Quick Release Lock into the Pivot
Box. Then use the crank handle on the Conversion Box to
disengage the top rail from the upper arm and engage the
Conversion Box with the locking receiver at the top track.
Step F3
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.
Step F4
Open and close all single/double end panels (non-
sliding). Move sliding panels into the stacking bay. The
panels should move easily in the opening and should
stack smoothly in the stacking bay. Check to see if all
upper track components are properly installed. Check if
all angles are correct. Each leg of the stacking bay track
should be equidistant at all points.
Step F5
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. If the head track is recessed into the
ceiling, make sure any receivers installed on the side of
the head track are accessible. 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 HSW75  SINGLE
TRACK SLIDING SYSTEM
For opening and closing the single track folding 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.
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 diiculties 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 and only move one
panel at a time in a gentle manner.
Opening and Closing a Unit.
1. For opening, if there are any single/double action
panels, convert them to sliding panels as per
instructions below.
2. If there are non-sliding end panels, open these
panels first.
3. Disengage the locking points on each panel and
move only one panel at a time. 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.
c. Concealed Locking – lift up/down edge bolt with
hand or foot.
d. Automatic Locking – when adjacent panels
are pulled together and properly aligned, the bolt
automatically engages.
4. Note that there is a carrier at each upper corner of
a sliding panel. Look at the head track within the
opening and note the switches that lead the head
track from the main opening to the stacking bay.
Move the panel from the side in the direction of the
stacking bay and the roller with top guide will follow
the line in the switch to the right stacking location.
If necessary, grasp the panel by the edges with both
hands as high on the panel as possible to locate him
in the right location.
5. Similarly, slide all the remaining panels through the
appropriate switch into the stacking bay.
6. In most cases, panels can be pushed in place with
one hand pushing on the edge of a panel. Move
evenly one panel at a time and keep panels as
vertical as possible and push into the stacking bay.
Do not force. Avoid any pendulum movements,
otherwise rollers may get damaged.
7. If there is more than one stacking bay, please be sure
the panels are stacked in the correct stacking bay.
8. For closing, proceed with the sliding of the panels in
reverse order. To pull the panels from the stacking
bay, you will need to grasp panels by the edges with
one hand as high as possible. Move evenly and keep
panels as vertical as possible. Avoid any pendulum
movements.
9. Make sure each panel is placed in its proper position
in the opening and engage the locking point before
moving the next panel. Do not force any locking
point.

10. Convert the single/double action sliding panels from
sliding panels to swing panels as per instructions
below.
CONVERSION OF A SINGLE/DOUBLE ACTION
SLIDING PANEL FROM A SLIDING PANEL TO A
SWING PANEL
1. When the unit is closed, it would be best to make
sure all the locking points on every sliding panel are
properly engaged. Pay special attention to the Quick
Release Lock on the single/double action sliding
panels to the Pivot Boxes on the these panels. They
have to be fixed in place first before you proceed.
2. Using the crank handle supplied, turn the slot in the
Conversion Box located on the upper arm of the top
rail so the upper arm engages to the receiver on the
side of the head track and disengages from the top
rail. Turn about 8 revolutions in a counter clockwise
direction until the bolt sticking out has disappeared.
3. The single/double action sliding panel can now
be used as a regular swing door with appropriate
hardware.
CONVERSION OF A SINGLE/DOUBLE ACTION
SLIDING PANEL FROM A SWING PANEL TO A
SLIDING PANEL
1. Close the swing panel.
2. Using the crank handle turn the slot in the
Conversion Box located on the upper arm of the
top rail so the upper arm disengages from the head
track and engages to the top rail. Turn about 8 - 10
revolutions in a clockwise direction until there is a
slight resistance.
3. Release the Quick Release Lock on the pivot side
to disengage the locking from the Pivot Box and if
necessary unlock the profile cylinder.
4. The single/double action sliding panel can now slide
away just like all the other 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
IMPORTANT: THE QUICK RELEASE LOCK ON
THE PIVOT SIDE OF A SINGLEDOUBLE ACTION
SLIDING PANEL HAS TO BE SECURED TO THE
SOCKET IN THE PIVOT BOX, FIRST, BEFORE
YOU PROCEED AND THE SWING PANEL CAN
FUNCTION PROPERLY. OTHERWISE, IT WILL
NOT BE STABLE AND CAN FALL AND HURT
SOMEBODY.

NANAWALL HSW75 OWNER’S MANUAL

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. Adjust brush sealing
c. Check height adjustment and setting
of each panel
d. Check if all panel end caps are in place
e. Check if all carriages can be moved easily
f. Check if counter nuts and safety screws
on carriages are adequately fastened
g. Check if pin carriers in pivot panels are
in the right position
h. Ensure that the lower locks can be
moved easily
i. Check if floor sockets and pivot boxes
are adequately fastened to the floor

NANAWALL HSW75 OWNER’S MANUAL

j. Remove any dirt from the floor sockets,
pivot boxes and bottom door closers
k. Ensure that any lock and profile cylinder
can be moved easily
l. For single/double action sliding panels,
check position of the reversing gear
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 single track sliding 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 all glass panels may not be equal. Contact
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 get in touch with NanaWall before you replace
a glass pane in order to get the right material and
instructions to glaze the panel!

SOME SPECIFIC SUGGESTED MAINTENANCE
FOR COASTAL SALT WATER AND OTHER
EXTREME ENVIRONMENTS:
Please note that the environment within one mile of a
sea coast can be extremely corrosive. Products installed
in this environment will typically deteriorate sooner than
products installed in a less severe environment.
1. Open and close unit completely at least once a week
and inspect all surfaces. Salt and other corrosive or
abrasive materials such as sand must not be allowed
to build up on any surfaces, including all hardware
and sill. The sill and head jamb tracks should be free
from all dirt and debris. There should be no standing
water in the track in the sill. All hardware should be
intact and operating properly.
2. All surfaces must be cleaned with a mild detergent
soap and fresh water at least every month and more
frequently if necessary. After washing, the surface
should be rinsed thoroughly with clean water and
allowed to dry. For cleaning, do not use abrasive
household cleaners or materials like steel wool or
hard brushes that can wear and harm finishes. Any
glass cleaner used should not be allowed to run down
on any other surface.
3. Any breaches in the paint coating, such as scratches,
chips or areas of abrasion, must be repaired
immediately.
4. Every 3 months, thoroughly clean and dry all upper
and lower rollers and all hinges. Liberally apply
lubricant such as Teflon spray (no grease) on the
wheels and bearings of the rollers. Oil all hinges
including the hinge pin with light weight lubricating
oil or Teflon spray.
5. As with any painted surface exposed to corrosive
environments, every 6 months apply a wax to the
outside of the painted panel and painted track. If the
system includes corner connections make sure the
wax penetrates the connection joints.
