NANAWALL WD66 OWNER’S MANUAL

Standard Wood Framed Folding System
This Owner’s Manual contains instructions on the installation, operation, maintenance and warranty of the NanaWall WD66 Standard Wood Framed Folding System. This manual is to be used by the installer for installation and is to be kept by the Owner for reference. Replacement parts can be ordered directly through NanaWall Systems.

Installation Instructions

The installation of the WD66 System requires a working knowledge and experience in the use of tools, equipment and methods necessary for the installation of aluminum doors, windows, storefronts, and/or partitions. This practice assumes a familiarity with preparing a proper and structurally sound opening, proper anchorage, waterproofing, caulking, and sealing and assumes an understanding of the fundamentals of building construction that affect the installation of large door systems.
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. NanaWall 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.
The WD66 system is shipped with all necessary components. However, not included are screws, bolts, shims, etc. to anchor the unit to the rough opening.
The frame is shipped knocked down and needs to be assembled. Panels are pre- assembled with or without glass, ready to be attached to the installed frame. In most cases, all hinges, weather stripping, multiple locking, and flat handles are pre-attached to the panels and frame components.
DESCRIPTION OF SUPPLIED PARTS
Check all parts carefully before assembly. Depending on the model, some of these parts may already be preinstalled on the panels. Check that the sizes of the frame components and panels match with what was ordered. In the cardboard box attached to the frame components that contains hinge pins and various hardware, inspect the elevation drawing, indicating size, configuration, and labeling of the unit ordered. Confirm whether the unit ordered is WD66/o, top- hung or WD66/u, floor supported. For orders with multiple units, do not mix and match panels and frames, even if two units are exactly the same. Below is a list of supplied parts.
Always looking from inside.

  • Left side jamb, labeled L, and right side jamb, labeled R.

  • Head jamb, labeled O, and sill, labeled U. (In some instances the head jamb and sill may be in segments.)

  • Pre-assembled panels, that means locking mechanism with flat handles are installed on the panels. The number of panels depends on the model ordered.
    The sequence of labeling of panels starts from the left with the left most panel labeled Panel 1. If supplied unglazed, panels have to be glazed before being installed in the opening. See Appendix A: Glass Installation and Glazing.

  • For certain configurations with even number of panels on a side, separate running posts.

  • Upper and lower running carriage sets – one set for each pair of folding panels. (An extra set for each pair or multiple pairs of folding panels unhinged to a side jamb or other panels).

  • A certain amount of hinge pins and set screw to  secure the hinge pins.

  • Lever handles, other handles or other entry hardware as ordered. These may be pre-attached to the panels.

  • Panel holder – one for each swing door not attached to a side jamb.

HANDLING OF COMPONENTS

  1. Upon receipt, inspect the shipment to ensure it is in good condition.
  2.  Make sure that the small cardboard box with the hinge pins and other hardware does not get lost.
  3.  Store in a clean and dry location and protect against defacement or damage, especially to the edges of panels.
  4.  Wood components should not be subject to extreme or rapid changes in heat or humidity, such as forced heating to dry out a building.
  5.  All wood surfaces including all edges (top, bottom and sides) should be completely sealed and finished promptly.

PREPARATION OF THE ROUGH OPENING

For necessary clearance and adjustment space, make rough opening about 3/4″ wider and 3/8″- 1″ higher than the outside frame size of the unit ordered (check to comply with applicable codes for maximum shim space allowed, especially in high windload areas). It is important that the opening be the correct size. Note that the outside frame height of the unit ordered is measured from the bottom of the sill and not from the finished floor.
Allowance must be made in height for the portion of the sill that is below the measured opening.
IMPORTANT: Because of the large opening sizes and the weight and movement of the panels, any application should take into consideration the following:

  1. The structural integrity of the header 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″. Structural support for lateral loads (both windload and when the panels are stacked open) must also be provided.

  2.  A qualified engineer or architect should be used to determine the proper construction details and header to be used in your particular application.

  3.  THE ROUGH OPENING SHOULD BE 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 AND OTHER SIMILAR PRECISE MEASURING  EQUIPMENT SHOULD BE USED.

  4.  With a recessed sill, if concrete is to be poured after the installation of the unit, the sill has to be securely attached to the construction. If the sill is to be cast in concrete, then an expansion gap with appropriate material has to be created next to the sill.

  5.  With a low profile saddle, some resistance to water infiltration may be achieved by installing drain connections to the outside. See Diagram 2.
    If any anchorage or drain connection holes are made through these drain channels, make sure that they are properly sealed to prevent any water leakage. The open ends of these drain channels at each end of the sill should also be properly sealed. Alternative anchoring systems for the sill (without using screws through the drain channels) are using L brackets attached to both sides of the sill.

  6.  For better performance and protection, any exterior folding system should be installed under an overhang or with other similar protection.

  7.  For better performance it is recommended that all dead loads such as upper levels, roof, etc. be constructed before a unit is installed.
    Properly flash and waterproof around the perimeter of the opening, especially at the sill. Make sure you seek proper professional advice for the appropriate construction needed for your particular application. DO not install unit in structures that do not allow for proper management/drainage of moisture. To avoid future problems, do not install your unit until the rough opening has been correctly prepared.

WOOD FINISHING AND MAINTENANCE

RECOMMENDATIONS
NanaWall wood framed systems are shipped with a factory applied layer of a waterborn translucent coat of sand sealer or primer, which is an acrylic- copolymer-dispersion from Sikkens (www.nam.sikkens.com). NanaWall aluminum clad wood framed systems are shipped with a similar additional coat. These factory applied coatings are not a sufficient and adequate protection from the elements and at least two coats of a final finish need to be applied in the field.
IMPORTANT: Immediately upon receipt of the unit and prior to installation and exterior exposure to weather elements, all wood surfaces including all edges (top, bottom and sides) should becompletely sealed and must be protected with a good quality finish. Before installation, keep the units in a dry and clean location, store, and stack them properly to avoid twisting or warping of the panels and frame components.
To complete the wood surface treatment use compatible finish material. If you think the product that you are intending to use is not compatible, then completely remove all pre-applied coats by chemical stripping (please follow the direction of the product) or by sanding off. Do not use power wash or excessive water. Then apply  a good quality sealer or primer and continue applying thenecessary coats as recommended by the product you have chosen.
CAUTION: Not all available paints and stains, nor the customer’s specific application requirements can be evaluated. Your local paint professional should know of suitable finish systems that give satisfactory results in your region. It is highly recommended that top quality finishes be selected, and the directions of the products be followed explicitly.
In general, the surface must be prepared by cleaning off dust and any debris. With 180-220 grit sandpaper, sand lightly and thoroughly all surfaces to be painted. Do not use steel wool or silicon carbide type sandpapers. Then clean the surfaces before applying paint, etc. For best performance, a minimum of two topcoats should be applied.
Always make sure that you apply the coatings on a hidden area before finishing the whole unit to make sure you are satisfied with the results.
Ensure not to apply the coating material on to hardware, gaskets, glass, sealant, or aluminum surfaces to maintain proper product performance.
All damages or scratches during installation on the surface coating should be immediately touched up.
WOOD SIMULATED DIVIDED LITES (SDL)
It is recommend that after completing the surface treatment of the SDL and after allowing for adequate drying time, to seal the gaps between the SDL and glass with a durable weather resistant caulking material, which is compatible with the surface treatment material.
MAINTENANCE OF WOOD UNITS
As a general guideline it is recommended that every 1/2 year or earlier, to inspect visually the surface and if necessary re-finish in the same manner as per instructions above. The timeframe may vary on weathering, exposure conditions and altitude. Whenever
damage is visual, it should be repaired immediately.

UNIT INSTALLATION

The Installation of the folding unit is described in the following categories:
A. FRAME ASSEMBLY AND INSTALLATION
B. PANELS AND FOLDING HARDWARE INSTALLATION
C. FINAL STEPS
A. FRAME ASSEMBLY AND INSTALLATION
It might be easier to drill the holes as described in Step A8 before assembling the frame.
Step A1
Lay the four frame components flat on the floor and align the ends to be joined. If the head jamb and sill are provided in segments, then connect them first. Make sure that the frame components are in the correct positions.
The frame should be labeled U for sill, O for head jamb, and looking from inside, R for right side jamb and L for left side jamb. Note: If there are no weep holes in the sill, please check whether such holes are required and drill them if necessary. Please be careful to avoid scratching or damaging the components.NanaWall WD66 Standard Wood Framed Folding System -
scratching

Step A2
Make sure that the stainless steel insert for the sill of floor supported WD66/u are in the correct place (Illustration A1).
Step A3
For top-hung WD66/o L/R with unhinged pairs of panels not connected to a side jamb, see Step B7. The upper running carriage has to be inserted in the head track before assembling the frame.
Step A4
Assemble all frame parts as shown. Do not apply sealant to the corner joints yet.

Standard Wood Framed Folding System - EXAMPLE

Step A5
Do not screw the vertical side jambs to the head track nor the sill. It has to be possible to slide the side jamb inwards or outwards for adjustment.
Step A6
Be sure that appropriate flashing around the perimeter of the opening is installed. Set the assembled frame into the rough opening at the proper position relative to the header. Make sure the direction is correct with respect to inward or outward opening.
See Diagram 2 for Suggested Installation Details. Please note that these are suggestions only and that these may not be suitable in all applications.
Step A7
Temporarily secure the frame to the rough opening with clamps.

TOP-HUNG LOW PROFILE SADDLE SILL
For resistance against wind driven rain, recommend the following by others:

  1. Remove the gasket covering the inner water channel.
  2.  Provide necessary weep holes at bottom of channel and through to the outside face of the sill.
  3. Make necessary drain connections.

Step A8
Looking on a standard installation, which is limited to areas with a basic wind speed of not more than 90 mph, in a low rise building (max. 60 feet roof height),
Exposures B or C and a non critical status. Fasteners locations should start about 4″ from the interior edge, drillholes for the anchorage devices to connect the frame to the opening at a spacing of not more than every 16″ along the head jamb and the sill. On the head jamb and sill an additional fastener should be placed at the meeting point of panels in the closed position and anchorage points every 4″ in the stacking area on either side. The spacing of the side jamb should be about 14″ starting at the bottom, using an extra screw at the top. For installation that are beyond the above limitations, a structural engineer should be consulted for specific fastening requirements. For Florida installations, please see Appendix B for specific installation requirements.
Use appropriate screws or other equivalent anchorage devices depending on the adjacent substrate material and construction. Make sure they are corrosion resistant. Anchorage devices should penetrate or hold sufficiently  to the opening to withstand necessary structural loading.
Generally, for wood frame use #14 (1/4″ diameter) wood screws with 2-1/2″ minimum embedment, for concrete with a minimum compressive strength of 3,200 psi use 3/16″ diameter ITW Tapcons (concrete screws) with 1-1/4″ min. embedment. For masonry use 1/4″ diameter ITW Tapcons (masonry screws) with 1-1/4″ embedment. Standard installation into light gage steel substrates with a minimum of 18 gage (0.0451″ thick) should have 1/4″ diameter type 410 stainless steel self drilling screws. Into structural steel substrates thicker than 1/4″ should be pre drilled and 1/4″ diameter SAE Grade 2 bolts can be used.  Another option is to use type 410 stainless steel selfdrilling screws. For this option first drill small pilot holes. Make sure that the screw head with washer (if any) is small enough to fit inside the slot in the middle of the head jamb and sill; otherwise, it will interfere with the rolling of the running carriages.
Anchor through the center of the groove but make sure the screw or bolt head with washer bears on the aluminum. To maintain the thermal break, use PVC or nylon washers so that the screw heads do not bridge the aluminum.
DIAGRAM 3: SUGGESTED FRAME FASTENING POINTS
A = About 4″ from the interior edge.
B = Distance about 16″, except at the stacking area on one or both sides where spacing should be about 4 Plus extra screws at meeting point of panels.
C = Distance about 14″ from the bottom using extra screw at top.
See Appendix B for Florida installations.
Make sure that the frame is level, plumb and square at all points. There should be no unevenness or bowing.
If, for any reason, the floor is not level, shim with plastic horseshoe shims to the highest point of the floor,
provided there is still enough clearance at the top. Place plastic, horseshoe type shims tightly at every fixing point between the frame profile and rough opening. Use hard plastic horseshoe shims only.
Step A9
For the top-hung WD66/o and for the floor supported WD66/u anchor the sill to the subfloor.
The sill has to be installed in correct relation to the finish floor. Make sure that the sill is not tilted or twisted. Make sure that all holes drilled through the sill are properly sealed with silicone underneath and around the screws.
All weep holes in the sill are not to be obstructed. Make any necessary adjustments to level, plumb, and square before proceeding on.NanaWall WD66
Standard Wood Framed Folding System - FASTENING

Step A10
Anchor the side jambs to studs or walls. Make sure that the jambs are plumb and straight.
Be aware that the anchorage points in the side jamb with the lesser number of panels attached to it may in Step C6 need to be loosened to be able to move the side jamb to adjust the total width of the unit.
Step A11
As the sill is attached first, then the side jambs, now anchor the head jamb through the pre-drilled holes and shims. Make sure that the head jamb is level.
IMPORTANT: Make sure no shims are forced to ensure that frame sections are not bowed. Check frame constantly to be certain that it is level, plumb, and square. A transit and other similar precise measuring equipment should be used to make these determinations.
Step A12
IMPORTANT: Make sure that all the surfaces of the upper and lower tracks are clean and free of any debris, especially, cuttings from drilled holes. See Illustration A3.

B. PANELS AND FOLDING HARDWARE INSTALLATION
IMPORTANT: Look for glass stops to determine the interior side of a panel.
Step B1
On top-hung WD66/o insert all the upper running carriages into the upper track, through the slot on  one end of the head jamb. The lower running carriagefunctions as a guide in the sill. See also Diagram 2.
On floor supported WD66/u insert all lower running carriages into the sill. See Illustration B1. The upper running carriage is just a guide in the upper track. See also Diagram 2.
Step B2
Looking at the elevation drawing, first install panel(s) hinged to the side jamb(s). Align the hinge components  on the panel to the hinge components on the side jamb and insert the proper hinge pin. Insert the hinge pin in away such that the security set screw fit into the groove in the hinge pin. Loosen the set screw as needed to insert the hinge pin, tighten till it touch the pin and then back off a full turn. Use an Allen key. See Illustration B2.NanaWall WD66 Standard Wood Framed Folding System -
panel

Step B3
Again, looking at the elevation drawing, attach the next panel needed to create a folding pair by aligning the hinges and inserting the proper hinge pins. If necessary, place temporary blocks under the panels to assist in keeping the panels in a steady position. These two panels are connected with hinges according to Illustration B2.
Step B4
Close the folding pair by turning the handle 180°.
Step B5
Locking at the elevation drawing, now the upper and lower running carriage should be attached. Therefore they have to be inserted in the upper and lower track as described above under step B1.
In general the upper and lower running carriage enfold the hinge and the provided long screws with the selflocking nut secures the  assembly. See also IllustrationB3.
Step B6
Attach the next panel to this folding pair by demounting the long screw of the running carriage that way that the  hinge part of the next panel can be safety inserted intothis assembly.
Step B7
For a running post at the end of a sequence of even number of panels or for unhinged paired panels, the upper and the lower carriage are pre-attached to the running post.
Step B8
Complete the assembling of the upper and lower running carriage as shown in Illustration B3. Secure the long screw with the self-locking nut in such a way that between 1 and 2 full treads are showing through. Do not over tight, because this affects the operation. Here the security set screw is not needed. Insert the proper hinge pins on the remaining hinges.
Step B9
Attach additional panels in the same manner.
After installation of each panel, check to make sure that the panel is vertically straight.
C. FINAL STEPS
Step C1
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, so it is not longer than 1-1/2″ to 2″ depending on locking type.
Step C2
IMPORTANT: For swing panels not attached to a side jamb, attach the panel catch to the stile with the handle and the catch counter-part to the opposite stile of the adjacent panel. Follow the specific instructions that are on the sheet in the panel catch kit. The
purpose of this is that the swing panel should always be opened and engaged into the panel catch before the folding panels are to be opened.
Step C3
Close and lock all panels into position.
Step C4
Check all horizontal joints:
Make sure the head jamb and sill are still level. Then along the entire width of the opening, check the spacing between the head jamb and each panel should be about 5/16″ along the entire length of the unit. Check especially to see if the upper corner of a panel where the running carriage is located is not higher than the other corner of the panel. If it is slightly lower (not more than 1/16″), it is okay. Then along the entire width of the opening, check the spacing between the sill and each panel, which should be about 3/8″ along the entire length of the unit. Proper spacing is critical for proper operation of the unit.
Step C5
Check all vertical joints:
Make sure that the side jambs are still vertically straight.
All vertical spacing between side jamb & panel rebate and the join where swing panel meet swing panel should be 5/16″, spacing between panel & panel and panel & running post should be about 1/2″.
Step C6
If the spacing on the vertical joints are not correct, adjustments can be made by moving the side jamb(s) as needed.
Step C7
Various adjustments can be made by adjusting the hinges and running carriages to correct some minor spacing and operational problems. Adjustments are complex and if not performed properly, may make matters worse. Only a trained installer or with proper guidance from NanaWall should any adjustments be attempted. Please contact NanaWall.
Step C8
Check that the system operates and functions properly.
The panels should be able to be moved easily by one person without much effort (for not more than 6 panels to one side) when opening or closing and all shoot bolts should engage smoothly. If the panels do not move easily or a lot of effort is needed, the indication is that the unit is not properly installed. Correct any problems before finish trimming.
Step C9
Seal the joints [A] on the exterior between the vertical jamb and the sill with exterior grade sealant. Therefore lift the gasket, re-install and glue it afterwards. Also fill the space [B] underneath the vertical frame and the sill with exterior grade sealant generous to avoid water leakage into the wall and to protect the wood. See Illustration C1.NanaWall WD66 Standard Wood Framed
Folding System - SEALING

Step C10
Apply a thick bead of exterior grade sealant with a backer rod if needed on the joint between the sill and sub floor on both sides along the length of the sill. Do similar for the gaps between the head jamb and side jambs with the opening.
Step C11
Finish any waterproofing, flashing, trim and sealant needed around the perimeter of the opening.
Important: Make sure any weep holes in the sill are not blocked.
Step C12
To prevent uncontrolled movement of the panels when in open position, place appropriate door holder by others as needed.
PROTECTION OF UNIT DURING 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 FOLDING UNIT
For opening and closing the folding system, please observe the special notes on the following pages in as far as they relate to your folding system.
When operating the folding system similar to any other door, please do not place your fingers between the panels/pivot points. You may hurt them!
Do not have anyone not properly trained on operation and children operate the unit.
Do not force the system if not operating properly.
Please have it repaired as soon as possible by a qualified technician.
Anchor panels when in the open position to prevent uncontrolled movement, especially in windy conditions, that might cause damage and injury.
It is highly recommended that if not used, the NanaWall folding unit be kept closed as much as possible, in order to provide best security and weather resistance. When closed, please engage all locking mechanisms fully.
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.
With a Swing Panel Attached to a Folding Pair

  1. Open the swing panel a full 180° and connect to the panel catch on the adjacent panel.
  2. Disengage the locking points on all the other panels.
  3.  Slide folding panels, starting with the pair adjacent to the swing panel.
    For closing, proceed in reverse order.NanaWall WD66 Standard Wood Framed
Folding System - Folding Pair

Without a Swing Panel

  1. Disengage locking points on primary opening panel pair and fold it slightly.
  2.  Do the same with any adjacent panel pair.
  3. Slide folding panels completely to the side.
    For closing, proceed in reverse order.

With Unhinged Paired Panels and No Swing Panel

  1. Disengage locking points on primary opening panel  pair and fold it slightly.
  2.  Do the same with any adjacent panel pair (s).
  3.  Slide folding panels into desired stacking position.
    For closing, proceed in reverse order.

OPERATING THE SL-MULTIPOINT LOCKING ON THE PRIMARY SWING PANEL

NanaWall WD66 Standard Wood Framed Folding System -
LOCKING

Disengaging locking points (Note that this is not one motion operation. Key or thumbturn must be unlocked first.)
Be sure to check that the door is locked. The door is locked, when the handle cannot be depressed.
Engaging the locking points and locking

  • Turn handle up about 45° to engage the locking points. Then let it move back into its normal position.

  • Only now can it be locked with a key on the outside or a thumb turn on the inside.
    Unlock and disengaging the locking points

  • Unlock the lock with key or thumb turn.

  •  By operating the door handle downwards, the locking points at the top and the bottom are disengaged.

RECOMMENDED MAINTENANCE OF NANAWALL PRODUCTS
Some General Considerations on all Projects:

  1. It is important that the product is installed correctly.
    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 (except when there are very large panels or when there are
    more than 6 panels folding to one side). All locking points should engage smoothly. There should be no rubbing on the floor and no binding. When the unit is closed, the reveal between panels and head jamb and between panels and sill should be consistent. There should be no daylight seen from the inside. Please have all problems corrected as soon as possible by a qualified technician.

  2.  From time to time, due to building movement or settlement, a unit may need to be adjusted by a qualified technician 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 for air and water infiltration, structural loading and forced entry.

  5. Periodically, inspect the sealant/caulking on the exterior perimeter of the unit. It is extremely important that the sealant/caulking remains intact and in good condition. Trim off any old, loose caulking and seal any gaps with a good quality caulk.

  6.  Check that all weep holes are clean and clear of any obstructions. Remove debris and other foreign bodies which have dropped into the tracks in the head jamb and sill immediately to prevent damaging the running carriages and guide trolleys. Clean all components as needed.
    Check gaskets for proper seating and condition. Remove dust and any deposits from these gaskets.

  7.  The finished aluminum or wood 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 sufficient. Stubborn stains and deposits may be removed with mineral spirits. For wood surfaces, superficial surface dirt can be removed by washing with water and a soft-bristled, long-handled brush. 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 affected by strong organic solvents. Superficial damage to the aluminum surface must be touched up immediately with proper touch up paint.

  8.  If it is a wood product, the surface should be visually inspected every six months or earlier, depending on the exposure of the NanaWall unit. Periodically repaint or restain the wood as needed. Exposure to the environment will break down the finish and compromise its protective features if not refinished. See Finishing Recommendations in the Owner’s Manual of the wood systems.

  9.  All hardware, hinges and handles should be periodically cleaned with a soft cloth and mild cleanser. Excessive abrasive rubbing should be avoided. Please note that oil rubbed brass is a finish that will develop its own unique patina over time.

  10.  About every six months, apply lubricant to all the hinges and Teflon spray to the running carriages and guiding trolleys.

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 completely a unit at least once a week and inspect all surfaces.
    a. 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.
    b. The sill and head jamb tracks should be free from all dirt and debris.
    c. There should be no standing water in the track in the sill.
    d. 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.
    a. After washing, the surface should be rinsed thoroughly with clean water and allowed to dry.
    b. For cleaning, do not use abrasive household cleaners or materials like steel wool or hard brushes that can wear and harm finishes.
    c. 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.

GLASS INSTALLATION AND GLAZING

This section applies only if you need to install glass for any reason or if glass setting blocks need to be adjusted. Proper glass installation is critical, as, with the NanaWall folding system, glass is a structural part of the panel. Glass stops and glazing gasket are to be used for “dry” glazing of each panel. Also needed are setting blocks. Use glass setting blocks with varying thickness made from hard plastic. Rubber setting blocks are not acceptable. Width of setting blocks should be at least 1/8″ wider than the glass thickness and 1/16″ to 1/8″ less than the width of the glazing pocket.
Glass, with appropriate dimensions, thickness and specifications will be needed. Depending on the model, widths of all glass panels may not be equal. Please note that glass is required to be fully tempered unless the unit is a window placed above a certain height from the floor. Check with all applicable codes and regulations. Float glass, including the glass components of insulated 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). Insulating Glass shall meet the requirements of ASTM E 774, Class A, B or C. Although glass installation with the “dry” glazing system is relatively straight forward, it is recommended that an experienced glazing contractor be used.
It is very important that the bracing direction and placement of glass setting blocks on opposite diagonal corners be correct. Setting blocks are to be placed only at opposite diagonal corners with corners alternating with each succeeding panel. This is necessary for the stability and balance of the panels when in operation. If not correctly braced, the unit will not operate properly.
The general rules for bracing are as follows:

  • For a panel attached to a side jamb, the lower brace should be at the lower corner closest to the side.
  • For a panel with a running carriage, the lower brace should be on the lower corner that is on the same side as the running carriage.
  • For a swing panel, the lower brace should be at the lower corner away from the stile with the locking hardware. See Diagram 1 for an example of setting block locations.

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. It would be best to install the glass on the panels before they are installed in the opening. Panels can be laid flat on sawhorses. If the panels are already installed, they can still be glazed.

  1. Close all panels and secure them with the multiple point lock bolts. Start with a panel that is attached to a side jamb or, in the case of unhinged pairs, closest to a side jamb.

  2.  Remove all glass stops on the panel. Be sure to protect the finish.

  3. Measure both the vertical and horizontal dimensions  of the glass and the panel opening. Subtract the vertical glass size from the vertical panel opening size.
    Divide the difference by two. This will give the nominal thickness of the setting block to use at the top and bottom rails. Several setting blocks of different thickness may need to be combined to obtain the desired thickness. Do the same for the horizontal
    dimension to obtain the thickness of the setting block to use at the stiles.

  4.  Place a setting block (or combination of setting blocks with desired thickness) on the bottom rail of the panel opening such that it is about 2″ from the bottom corner as determined by the bracing rules above.

  5.  Carefully place the glass in the opening, making sure it rests on the setting block. With insulated glass,  make sure that both inner and outer panes aresupported evenly.

  6. Place a second setting block in the same corner as the first setting block, but in the vertical direction  along the stile such that it is about 2″ above thecorner.

  7.  Place another setting block in the upper diagonal corner vertically on the opposite stile in the same manner. If necessary, apply a little adhesive that is non-damaging to the glass edge seals such as Dow Corning 791 silicone, to keep the vertical setting blocks from slipping.

  8. Place the last setting block on the upper rail on the same corner as the other upper setting block. To get a proper fit, shift the glass weight by lifting the panel up with a plastic pry bar at the lower corner below the upper setting block. These setting blocks should all fit snugly but should not be forced. Adjust the thickness of the glass setting blocks such that the panel is slightly out of square. The upper corner with the setting blocks should be about 1/16″ higher than the other corner.
    If the panels are large, additional setting blocks may be needed midpoint on the stiles, especially on a swing panel.

  9.  For aluminum systems insert the glass stops so that  they snap into the panel profile. For wood systems insert the glass stop firmly into position, so they are flush with the panel. Nail to the inner side of the panelwith small finish nails. Start with the top  and bottom stops and then the sides.

  10.  Insert the glazing gasket in the space between the glass and the glass stop. First, cut the gasket to a length a little longer than the actual length of the glass stop because gasket material may shrink at low temperatures. Do not stretch or pull the gasket in any
    manner. If necessary, use soapy water to lubricate the gasket to make insertion easier.

  11.  Make sure that the stops are locked firmly and securely into position and are flush with the rest of the panel profile.

  12.  Repeat Steps 2 to 12 for each of the other panels. Setting blocks for each succeeding panel must be placed at diagonally opposite corners in the proper sequence as set forth in Step 1. See Diagram 1 for an example of a three panel unit.

  13.  After installing the panels, assuming that the head jamb and sill are level, check to see if the gap between the panel and head jamb and panel and sill is even across the width of the panel. With the glass weight, the out of square panels should become almost even. If they remain slightly higher in the upper corner with the setting blocks it is okay. If not, then the lower and upper setting blocks thickness need to be adjusted. Panels have to be braced correctly for proper operation.
