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

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.
