This Manual contains instructions on the installation, operation, maintenance, and warranty of Generation 4 Folding Glass Walls by Nana Wall. 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 Nana Wall Systems.

Generation 4 Product Family

The principle of installation within the product family is the same for all Generation 4 systems (profile depth varies by system).
For comparison, below are typical head track vertical cross section details of the different systems.

INSTALLATION INSTRUCTIONS

The installation of the Nana Wall 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, sealing, and assumes an understanding of the fundamentals of building construction that affect the installation of large aluminum door systems.
Using an independent Nana Wall Certified Installer is highly recommended. If an independent Nana Wall Certified Installer cannot be used, the installer should have at least some experience in installing Nana Wall systems.
IMPORTANT: Read these installation instructions before carrying out any installation work. Install as recommended; otherwise, the unit may not function properly and any warranty, written or implied, will be void.
As regulations governing the use of glazed windows, doors, storefronts, and/or partitions vary widely, it is the responsibility of the customer, building owner, architect, contractor, or installer to ensure 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 customer, building owner, architect, contractor, or installer to comply with all applicable laws and ordinances, and
safety and building codes.
The Generation 4 systems are shipped with all necessary components. However, the anchoring materials, such as the correct screws, bolts, shims, and sealants required to anchor the unit in the rough opening are not part of the scope of supply and are not provided by Nana Wall. Selection of the proper anchoring materials are critical to proper installation as outlined in these instructions.

DESCRIPTION OF SUPPLIED PARTS
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, multipoint locking, and flat handles are pre-attached to the panels and frame components. Check all parts carefully before assembly. Depending on the model, some of these parts may already be pre-installed on the panels. Check that the sizes of the frame components, panel sizes, and configurations match what was ordered according to the signed product drawings that show all dimensions of the system.
An accessory box is added to the crates that contains hinge pins, rollers, various hardware parts, and printed documents. Inspect the product drawings indicating size, configuration, and labeling of the units ordered. Carefully note the information on the rough opening allowances to make sure the rough opening is prepared properly for the system to fit correctly when installed. 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 the main components supplied. Always looking from inside:

• Left side jamb (labeled L) and right side jamb (labeled R).
• Head (top) track (labeled O) and sill track (labeled U). (In some instances, the head track and sill may be in segments and require joining in the field.)
• Pre-assembled panels mean the locking mechanism with flat handles are installed on the panels.
• The number of panels depends on the unit ordered. The sequence of labeling of panels starts from the left with the left most panel labeled Panel 1 as viewed from the interior.
• If supplied unglazed, panels have to be glazed before being installed in the opening. See Glass Installation and Glazing instructions section of this document.
• For certain configurations with even number of panels to one side, there will be separate running posts.
• Upper guiding rollers and bottom rollers – one set for each pair of folding panels.

HANDLING OF COMPONENTS

1. Upon receipt, inspect the shipment to ensure it is in good condition. Any potential damage must be noted on the Bill of Lading at the time of delivery by the customer. Any shipping damage to crates and components inside must be photographed and reported to Nana Wall immediately. Please email pictures with your order number to service@nanawall.com and contact the Service Department at (800) 873-5673 ext. 256.
2. Make sure that the accessory box with the hinge pins, rollers, various hardware parts, and printed documents does not get lost. Please also verify the product drawings for this order and the Installation and Owner’s Manual are in the box. If these are missing, please contact Nana Wall at info@nanawall.com to get these documents.
3. Store in a clean and dry location and protect against defacement or damage, especially to the edges of panels.
4. Always practice safety. Wear the appropriate eye, ear, and hand protection items, especially when working with power tools. These panels can be heavy and awkward to handle. Use appropriate assistance and safety procedures, including safe lifting techniques, to avoid personal injury and damage to product.

PREPARATION OF THE ROUGH OPENING
All rough opening spaces and allowances shown in the product drawings are meant for shimming the system to be installed perfectly plumb, level, and square. For necessary clearance and shim adjustment space, rough opening is suggested to be 3/4″ wider than the unit width and 1″ taller than the unit height for vertical measurements of the unit ordered (check to comply with applicable codes for maximum shim space allowed, especially in high wind load areas). It is important that the rough 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 finished opening. An important reference for the preparation of the rough opening is the finish floor height.
It is highly recommended to install this system in a rough opening only and return all finishes to the system frame after proper installation. The shim space around the system is required—if the system is installed into a finished opening there will be space  exposed around the system that will still need to be trimmed. Under no circumstances should the system be installed on compressible substrates such as sheetrock.

IMPORTANT: Because of the large opening sizes and the weight and movement of the panels, any application should take into consideration the following Rough Opening Steps:

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/720 of the span or 1/4″. Structural support to prevent movement due to lateral loads (when the panels are closed such as wind load, or other loads, and when the panels are stacked open) must also be provided. In addition, point loads for the posts supporting the header must be reinforced to prevent compression.
2. The surrounding substrates must be designed and anchored to properly transfer all loads to the main building structure.
3. A qualified engineer or architect should be used to determine the proper construction details and the header to be used in your particular application.
4. THE ROUGH OPENING SHOULD BE LEVEL, PLUMB, AND SQUARE AT ALL POINTS. There should be no unevenness or bowing. Make sure that the header, side posts, and sill are not twisted. There should be no bumps on the floor. Make sure that the finished floor around the opening is low enough to allow proper clearance for opening/closing the panels. The side posts should be in the same vertical plane and not offset to each other. The RO header and sill need to be level and parallel and the jambs should be plumb and parallel. A TRANSIT OR ROTARY LASER LEVEL AND OTHER SIMILAR PRECISE MEASURING EQUIPMENT SHOULD BE USED TO VERIFY THE ROUGH OPENING IS PREPARED PROPERLY.
5. With a recessed sill, if concrete is to be poured after the installation of the unit, the sill MUST 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.
6. With the Hybrid and Raised sills, the weep slots in the sill must be unobstructed and properly drained.
7. With a Low Profile Saddle sill, some resistance to water infiltration may be achieved by installing weep holes and drain connections to the outside. The option to install weep holes and drain connections is to be decided and provided by the project architect or customer, NOT by Nana Wall.
8. For the Hybrid, Raised, and Low Profile Saddle sills, location of drain connections and flow of water is determined by others according to the surrounding conditions. See sections Weep Hole Pattern – Low Profile Saddle Sill and Suggested Typical Installation Details of this document.
9. For better performance and protection, any exterior folding system should be installed under an overhang or with other similar protection.
10. For better performance, it is recommended that all dead loads such as upper levels, roof, etc. be constructed before a unit is installed to limit the deflection of the header after installation of the door system.
11. Waterproofing and envelope details are not part of the base Nana Wall installation and will be unique to each project—proper flashing, waterproofing, and envelope details around the perimeter of the opening, especially at the sill, are to be designed and completed by others. This may not be part of the scope of work from the independent Nana Wall Certified Installer.
12. Nana Wall systems DO NOT come with any nailing flange. Therefore, it must be confirmed that the entire opening and finished installation is prepared against any water or air infiltration beyond the system frame.
13. Make sure you seek proper professional advice for the appropriate construction, waterproofing, and building envelope details needed for your application and jurisdiction. Do not install unit in structures that do not allow for proper management / drainage of moisture.

IMPORTANT: (For Wood and Clad Systems) Immediately upon receipt of a NW Wood 540, NW Acoustical 545, or NW Clad 740 unit, and prior to installation and exterior exposure to weather elements, all wood surfaces including all edges (top, bottom, and sides) should be completely 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. See Maintenance section of this manual for additional information.

IMPORTANT: To avoid future problems, check the condition on site before starting the installation. Do not install your unit until the rough opening has been correctly prepared.

INSTALLATION OF FRAME AND UNIT
For frame and unit installation, please see section Generic Installation Illustrations in this document.
FINAL STEPS
Finish any waterproofing, flashing, trim, and sealant needed around the perimeter of the opening to be designed and finished by others.

IMPORTANT: Make sure any weep holes in the sill are not blocked.
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.

Rough Opening Preparation

HORIZONTAL DIMENSIONS

The structual 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/720 of the span or 1/4″ (6 mm). Depending on the size of the panels, the weight can vary from 6 lbs/ft² (30 kg/m²) for double glazed to 8 lbs/ft² (40 kg/m²) for triple glazed. Please check your specifications for your glass type and weight.

VERTICAL DIMENSIONS

The structual 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/720 of the span or 1/4″ (6 mm). Depending on the size of the panels, the weight can vary from 6 lbs/ft² (30 kg/m²) for double glazed to 8 lbs/ft² (40 kg/m²) for triple glazed. Please check your specifications for your glass type and weight.

Recommended Fasteners and Shims

SELECTION OF APPROPRIATE FASTENERS
Use appropriate screws or other equivalent anchorage devices depending on the adjacent substrate material and construction. Make sure they are corrosion resistant, preferably a suitable grade of stainless steel. Anchorage devices should penetrate or hold  sufficiently to the opening to withstand necessary structural loading.

General recommendations for different substrates:
Wood Frame (minimum specific gravity of G=0.42):
Use #14 (1/4″ diameter) wood screws with 2″ minimum embedment.
Concrete (minimum compressive strength of 2,000 psi):
Use 1/4″ diameter ITW Tapcons (concrete screws) with 1-3/4″ minimum embedment with 1-1/2″ minimum edge distance.
Alternatively, 1/4″ stainless steel screws with expanding anchors may be used.
Masonry (grout filled block per ASTM C90 with FM=2,000 psi minimum):
Use 1/4″ diameter ITW Tapcons (masonry screws) with 1-3/4″ minimum embedment with 1-1/2″ minimum edge distance.
Structural Steel (minimum 1/4″ thick):
Use 1/4″ diameter self-tapping steel screws. Another option is to use type 410 stainless steel self-tapping screws with pre-drilled pilot holes.
Another option is to use 1/4″ diameter SAE 2 bolts in pre-drilled holes.

SELECTION AND USE OF INSTALLATION SHIMS
Use only hard plastic ‘horseshoe’ style glazier’s shims that are capable of sustaining the applicable loads. Wood or rubber shims are NOT appropriate. Shims are to be installed between the system frame and the building structure at every fastener location to keep the frame components straight, level, and plumb, without any twisting.

Generic Installation Illustrations

(For illustrative purposes, NW Aluminum 640 is used for the technical details and installation process.)

1. Pre-drill anchor points of frame components
   We recommend to lay the frame components down on saw horses. Take care to avoid scratching or damaging the profiles.
   Review the Anchoring Pattern Layout section in this manual for units Over 40psf and Lower than 40psf DP rating and determine which one is appropriate for your project.
   If your system includes the Low Profile Saddle sill, consult recommended Weep Hole Pattern section of this manual. This sill does not come pre-drilled. This way you can adjust the drainage approach to your project specific needs.

2. Side jamb (R) with cover profile
   Systems like 1L, 3R, or 5L configurations come with a side jamb cover. Unscrew and remove cover profile before you pre-drill the anchor points. Store with care until you reinstall it after unit is fully installed and adjusted. Verify that additional screws are in the accessory box.
   

3. Frame assembly
   Before assembly, make sure all shavings from drilling are removed from profile chambers. For wider systems, the head track and sill are provided in segments. Connect them first. Follow the instructions on the next pages. Lay components flat on saw horses or the floor. Apply exterior grade sealant to all connection points between the frame components. If possible, we recommend installing the complete frame as one piece into the opening.

27. Frame installation
    Before installing the frame, refer to the product drawings for specific details related to the finished floor height. Anchor sill to the sub floor in correct relation to the finish floor. Make sure the sill is not tilted or twisted and that all weep holes are not obstructed. Make necessary adjustments to level, plumb, and square before proceeding. Shim as necessary. Anchor the side jambs to studs or walls in the same manner. Check that jambs are plumb and straight.
    Anchor the head track through the pre-drilled holes and shims. Make sure the head track is level and not tilted or twisted.

28. Plumb, level, and square
    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 level or similar precise measuring tool should be used to make these determinations.

29. Handle with care
    Make sure that all the surfaces of the upper and lower tracks are clean and free of any debris, especially, cuttings from drilled holes.

30. Installation plates
    Use the supplied installation plates.
    Please note, a stainless steel washer that bears on the aluminum may be used if an installation plate is not available. All holes drilled through the frame must be sealed properly with an exterior grade sealant underneath the plate and around the screws. It is also recommended to seal underneath the sill along the thermal break to limit air infiltration.

Generation 4 System Components

Glass Installation And Glazing

This section applies only if you need to install glass for any reason or if glass shims need to be adjusted. Proper glass installation is critical, as with the Nana Wall folding system. glass is a structural part of the panel.
Glass stops and glazing gaskets are to be used for “dry” glazing of each panel. Also needed are shims. Use glass shims with varying thickness made from hard plastic. Rubber shims are not acceptable. Width of shims should not be more than 1/4′ (6 mm) wider than the glass thickness.
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 971 (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 or an independent Nana Wall Certified Installer be used.
It is very important that the bracing direction and placement of glass shims on opposite diagonal corners be correct. Shims 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 (please look at the diagram that shows the bracing direction of a 3-panel unit):

• For a swing panel attached to a side jamb, the lower brace should be at the lower corner closest to the side.
• For a panel with a bottom roller, the lower brace should be on the lower corner that is on the same side as the bottom roller.
•  For a swing panel attached to a folding pair, the lower brace should be on the lower corner that is on the same side as the bottom roller.

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 shim to use at the top and bottom rails.

4. Several shims 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 shim to use at the stiles. Place a shim (or combination of shims with desired thickness) on the bottom rail of the panel opening such that it is about 4′ from the bottom corner as determined by the bracing rules above. Make sure shim does not block the weep hole of the panel.

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

6. Place a second shim in the same corner as the first shim, but in the vertical direction along the stile such that it is about 4′ above the corner. 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 shims from slipping.

7. Place another shim 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 shims from slipping.

8. Place the last shim on the upper rail on the same corner as the other upper shim. 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 shim. These shims should all fit snugly but should not be forced. Adjust the thickness of the glass shims such that the panel is slightly out of square. The upper corner with the shims should be about 1/16′ -1/8′ higher than the other corner.
   If the panels are large, additional shims 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. Make sure that they do not interfere with any glass shim. For wood systems, insert the glass stop firmly into position. so they are flush with the panel. Make sure that they do not interfere with any glass shim. Nail to the inner
   side of the panel with 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. Shims for each succeeding panel must be placed at diagonally opposite corners in the proper sequence as set forth in Step 1.

13. After installing the panels, assuming that the head track and sill are level, check to see if the gap between the panel and head track, and panel and sill is even across the width of the panel. With the glass weight. the out of square panels should be slightly higher in the upper corner, which is okay. If not, then the lower and upper shims thickness needs to be adjusted. Panels must be braced correctly for proper operation.

**Recommended Maintenance of Nana Wall 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 or an independent Nana Wall 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 an independent Nana Wall 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 non-working 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 sill and other parts of the frame immediately to prevent damaging the top guides and bottom rollers. Clean all components as needed. Rinse the bottom track and check if water is exiting the system. 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, longhand led 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 Nana Wall unit. Periodically repaint or restrain the wood as needed. Exposure to the environment will break down the finish and compromise its protective features if not refinished. See Wood Finishing Recommendations section in this document.
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 three to six months, apply a Teflon based lubricant to all the hinges.  If operation of panels gets difficult, or at least every 12 months, clean the stainless steel surface of the track insert and the rollers and apply a Teflon based lubricant to the surface only and wipe off additional residues. The ball bearings of the rollers are encapsulated and maintenance free.  Any silicone, other oils, and “dry lube” sprays should not be used.

SOME SPECIFIC SUGGESTED MAINTENANCE FOR COASTAL SALT WATER AND OTHER EXTREME ENVIRONMENTS:
Please note that the environment within close proximity of any coastal area or body of salt water 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 track 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. Do not use a power washer or similar to rinse the unit.
   c. For cleaning, do not use abrasive household cleaners, or materials like steel wool, or hard brushes that can wear and harm finishes.
   d. 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. 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.

CLEANING AND CARE OF STAINLESS STEEL HARDWARE ON NANAWALL PRODUCTS
Stainless steel is an inherently corrosion resistant material, but some routine maintenance and cleaning is needed to keep surfaces in good condition so that the aesthetic appearance and corrosion resistance are not compromised.
Initial Cleaning
It would be best to protect all stainless steel hardware in the construction phase so that there is no damage. However, if there has been exposure, the following is recommended: Mortar and cement splashes can be treated with a solution containing a small amount of phosphoric acid or a proprietary stainless steel cleaner with phosphoric acid. Rinse with water (preferably deionized water) and dry.
Never allow mortar removers or diluted hydrochloric acid to be used on stainless steel.
Iron particles picked up from tools or from contact with structural steel, etc. must be removed immediately. Steel dust particles created during operations such as welding, cutting, drilling, and grinding of carbon steel will rust quickly and must be removed. At an early stage, light deposits can be removed mechanically using nylon scouring pads, such as those used in the kitchen. Alternatively, the contamination can be removed with a proprietary stainless steel cleaner containing phosphoric acid.
Maintenance Cleaning
Stainless steel may be exposed to a wide range of aggressive environments such as coastal salt water, industrial pollutants, salt spray from road de-icing salt, and atmospheric dirt. All cause brown staining to appear. During routine cleaning of at least every month and more frequently, if necessary, all accumulations of airborne contaminants, such as airborne chlorides, salt, or sulfur oxides, should be removed. In less aggressive environments, cleaning can be less frequent, such as every 3-6 months. Also, finger marks should be routinely removed. To remove fingerprints and other marks, soapy water or a mild detergent are usually safe and successful.
For more stubborn stains, mild household cream cleansers should be effective. This should also be suitable for cleaning off watermarks and light discoloration. After cleaning, remove the residues with deionized water and dry to avoid streaking and water marks.
Nylon pads can be used (such as those from 3M). When using nylon pads make sure you follow the original grain of the stainless steel surface. Maintain rubbing in a straight line or the surface will appear scratched rather than grained. DO NOT use cleaning steel wool, wire brushes, metal scouring pads, hard scrapers, or knives as the underlying stainless steel surface may become scratched or unwanted contaminates may be deposited on the surface of the stainless steel. To avoid “cross
contamination” from iron particles, ensure that cleaning utensils have not been used to clean other types of steel.
Alternatively, use a proprietary stainless steel cleaner containing phosphoric acid to remove contamination, rinse with deionized water, and dry. It is advisable that the entire surface is treated so that a patchy appearance is avoided. Cleaners that should not be used on stainless steel include: chloride containing cleansers, especially those containing hydrochloric acid, hypochlorite bleaches, and silver cleaners.
WOOD FINISHING AND MAINTENANCE RECOMMENDATIONS
Nana Wall wood framed systems are shipped with a factory applied layer of a water born clear coat of a sand sealer or primer. Nana Wall aluminum clad wood framed systems are shipped with a similar additional coat. These factory- applied coatings are not a sufficient or adequate protection from the elements and at least two coats of a final finish need to be applied in the field by others.
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 be completely 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, suitable compatible solvent or water- based products can be used.
CAUTION:
Not all available paints and stains, nor the customer’s specific application requirements can be evaluated. A local paint professional should know of suitable finish systems that give satisfactory results in the region where the unit is located. 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.
Please make sure none of the gaskets are removed or disposed of during the finishing process. It is possible to finish behind the loose parts of the gaskets without removing them. Some parts of the gaskets are glued in place and removing them may also remove some of the wood. 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 recommended 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, refinish in the same manner as per instructions given. The timeframe may vary on weathering, exposure conditions, and altitude. Whenever damage is visual, it should be repaired immediately.
