NanaWall SL60 Owner's Manual

Installation Instructions

The installation of the SL60 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 aluminum door systems.

Using an independent NanaWall Certified Installer is highly recommended. At the least, the installer should have 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. IF YOU HAVE ANY QUESTIONS REGARDING INSTALLATION, PLEASE CONTACT THE NANAWALL INSTALLATION DEPARTMENT.

CAUTION: As regulations governing the use of glazed windows, doors, storefronts and/or partitions vary widely, it is the responsibility of the customer, architect, contractor and/or building owner 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 customer, architect, or contractor to comply with all applicable laws and ordinances and safety and building codes.

The SL60 system is shipped with all necessary components, except correct fasteners and shims. These are not provided by NanaWall and are critical to proper installation as outlined in these instructions. The correct fasteners will vary depending on the specifics for each installation.

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 installed on the panels. The product drawings are in the small cardboard box attached to the frame components that also 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 SL60/o, top-hung or SL60/u, floor supported. 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. 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 supplied parts.

Component Identification

• Left-side jamb, labeled L, and right side jamb, labeled R.
• Head (top) track, labeled O for over, and sill track, labeled U for under. (In some instances, the head track and sill track may be in segments and will require joining in the field.)
• Pre-assembled panels with locking mechanism and flat handles. The number of panels depends on the model ordered. Panel sequence starts from the left, labeled Panel 1, as viewed from the inside. If supplied unglazed, panels must be glazed before installation. See Appendix B: Glass Installation and Glazing.
• For configurations with an even number of panels on a side, separate running posts. Rolling posts may be attached to panels and may need to be detached for installation if it is a top-hung system.
• 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.)

Handling of Components

1. Upon receipt, inspect the shipment for good condition. Photograph and report any shipping damage to crates and components immediately to Nana Wall. Email pictures with your order number 'xxxxx' to service@nanawall.com or call the Service Dept. at 800-873-5673 ext. 256.
2. Ensure the small cardboard box with hinge pins and other hardware is not lost. Verify Product Drawings and owner's manual are present. If missing, contact NanaWall at info@nanawall.com.
3. Store in a clean, dry location, protected from defacement or damage, especially to panel edges and glass. Store panels on their sides and frame components covered until installation.

Preparation of the Rough Opening

All rough opening spaces and allowances shown in the drawings are for shimming the system to be installed perfectly plumb, level, and square. For necessary clearance and shim/adjustment space, the rough opening is suggested to be 3/4" wider than unit width and 1" taller than the unit height. Check applicable codes for maximum shim space, especially in high wind load areas. The opening must be the correct size.

NOTE: The outside frame height is measured from the bottom of the sill, not the finished floor. Allowance must be made for the portion of the sill below the measured opening. The finish floor height is an important reference for rough opening preparation.

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. Installing into a finished opening will leave exposed space around the system that will need trimming. Do not install the system on compressible substrates like Gyproc.

IMPORTANT: Due to the large opening sizes and the weight and movement of the panels, consider 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 to prevent movement due to lateral loads (windload and stacked panels) must also be provided. Point loads for posts supporting the head must be reinforced to prevent compression.
2. A qualified engineer or architect should determine proper construction details and header.
3. THE ROUGH OPENING SHOULD BE LEVEL, PLUMB AND SQUARE AT ALL POINTS. THERE SHOULD BE NO UNEVENNESS OR BOWING. ENSURE THE HEADER, SIDE POSTS AND SILL ARE NOT TWISTED. THERE SHOULD BE NO BUMPS ON THE FLOOR. THE SIDE POSTS SHOULD BE IN THE SAME VERTICAL PLANE AND NOT OFFSET. THE ROUGH OPENING HEADER AND SILL NEED TO BE LEVEL AND PARALLEL, AND THE SIDE POSTS SHOULD BE PLUMB AND PARALLEL. USE A TRANSIT OR SIMILAR MEASURING EQUIPMENT TO VERIFY PROPER PREPARATION.
4. With a recessed sill, if concrete is poured after unit installation, the sill must be securely attached. If the sill is cast in concrete, create an expansion gap with appropriate material next to the sill.
5. With a low profile saddle sill, resistance to water infiltration may be achieved by installing weep holes and drain connections to the outside. Drain connections are an option provided by the installer or customer, not NanaWall. Location and flow of water are determined by others according to surrounding conditions.
6. Heavy gage metal studs require continuous wood backing for minimum 2 ½" fastener embedment.
7. For better performance and protection, exterior folding systems should be installed under an overhang or similar protection.
8. For better performance, construct all dead loads (upper levels, roof, etc.) before unit installation to limit header deflection after panel system installation.

Waterproofing and envelope details are unique to each project and are not part of the base NanaWall installation. Proper flashing, waterproofing, and envelope details around the perimeter of the opening, especially at the sill, are to be designed and completed by others. Seek proper professional advice for construction, waterproofing, and building envelope details. Do not install in structures that do not allow for proper management/drainage of moisture. Use peel and stick or ice shield under all bottom sills.

IMPORTANT: To avoid future problems, do not install your unit until the rough opening has been correctly prepared.

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

Step A1 – Preparation of the frame components

The recommended fastener location is determined from testing procedures for full specified performance. For standard installations (wind speed < 90 mph, low-rise building < 60 ft roof height, exposures B or C, non-critical status), consult the manual. For installations beyond these limitations, consult a structural engineer. For Florida installations, see Appendix A.

Verify the rough opening for proper fastener hole location as shown in Diagram 1. Fastener/attachment holes are drilled through the polyamide thermal break. Ensure screws span the thermal break to bear on aluminum. All joints require sealant to prevent water and air infiltration; commercial grade polyurethane sealant is recommended.

Side jambs are marked ‘L’ and ‘R’. Top head tracks are marked ‘O’ for ‘over’, and bottom sill tracks are marked ‘U’ for ‘under’.

Head and Sill tracks may be supplied in segments requiring joining. Lay out segments, mark fastener locations, drill holes, and join segments on the floor using supplied joining pieces (See Illustration A1). Use padding to protect frame pieces.

Fastening of Head and Sill Tracks

1. Single Parting Systems: Begin 16" on center fastening points from the 4" screw furthest from the stack end opening. Spacing on the stack end should be smaller, with extra screws at the meeting point of panels (approx. 4" apart), as shown in Diagram 1. This pattern mirrors on head and sill tracks. Protect tracks from marring by the drill chuck when drilling through the polyamide thermal break.
2. Bi-parting Systems: Begin 16" on center fastener points from the horizontal center of the opening. Smaller spacing on the stack end with extra screws under the stacking location (approx. 4" apart), as shown in Diagram 1. This pattern mirrors on head and sill tracks. Protect tracks from marring by the drill chuck.
3. Wide Systems with Multiple Track Segments: Joints in head and sill tracks require special fastener spacing. On both sides of the splice joint, place fasteners at 2" and 4" from the splice (total 4 fasteners per head/sill track). All fasteners must be supported by hard plastic shim stacks. See Diagram 1 and Step A7.

Fastening of Vertical Side Jambs

Drill fastener points 4" from interior corners at top and bottom. From the bottom fastener location, drill additional fastener holes not exceeding 14" on center. The distance between the two topmost fastener points on side jambs will be shorter than 14".

Step A2 – Selection of Appropriate Fasteners

Use appropriate screws or anchorage devices depending on substrate material and construction. Ensure they are corrosion-resistant, preferably stainless steel. Anchorage devices must penetrate or hold sufficiently to withstand structural loading.

• Wood frames: Use #14 (1/4" diameter) wood screws with 2 ½" minimum embedment.
• Concrete (min. 3200 psi): Use 3/16" diameter ITW Tapcons with 1 ¼" minimum embedment.
• Light gage steel substrates (min. 18 gage): Use 1/4" diameter type 410 stainless steel self-drilling screws (with minimum 2 ½" wood backing).
• Structural steel substrates (> ¼"): Pre-drill and use 1¼" diameter SAE Grade 2 bolts, or type 410 stainless steel self-drilling screws (drill small pilot holes first).

Diagram 1: Suggested Frame Fastening Points

Diagram 1 illustrates suggested frame fastening points for a standard installation. Key points are:

• A: Approximately 4" from the interior edge.
• B: Approximately 16" spacing, except at the stacking area where spacing is about 4", with extra screws at panel meeting points.
• C: Approximately 14" from the bottom, with an extra screw at the top.

Refer to Appendix A for Florida Installations. For nonstandard installations, consult a structural engineer.

Step A3

For a floor-supported SL60/u, ensure stainless-steel inserts for the sill are correctly placed (Illustration A2). Lay out frame components on the floor, correctly orienting ‘L’, ‘R’, ‘O’, and ‘U’ components. Note orientation for inward or outward opening. If using a low profile saddle sill track, orient it with the secondary weep channel to the inside.

Step A4

Apply exterior grade polyurethane sealant to all connection points between frame components (Illustration A3). Seal the ends of the sill to prevent water leakage.

Step A5

Insert corner connectors: longer side into the head track (and Higher Weather Performance sill track), shorter side into the side jamb. See Ill. A4 and A5. See Ill. A6 for side jamb to flush or low profile saddle sill connection.

Diagram 2: Suggested Typical Installation

Diagram 2 shows suggested typical installation details for outward opening and inward/outward opening configurations, including head tracks, side jambs, and various sill types (Higher Weather Performance Sill, Low Profile Saddle Sill, Flush Sill, Surface Mounted Interior Sill). Details are subject to change without notice and are not to scale. Waterproofing and building envelope details are not shown.

Key details from diagrams:

• Weep Holes: 5/16" DIAM. WEEP HOLES are drilled in the field by others at the center of each panel for Higher Weather Performance Sill. 3/8" DIAM. WEEP HOLES are drilled by others about 10" from each end and at every meeting point of panels for Higher Weather Performance Sill. 5/16" DIAM. WEEP HOLES are drilled by others in the inner channel at the center of each panel for Low Profile Saddle Sill.
• Sill Flange: For floor level adjustments, the sill flange is bendable or removable. Bend slowly with multiple passes using a rubber mallet. Avoid repeated bends to prevent separation. Bending the flange may affect ADA compliance.
• Sealing: Ensure fastener holes and sill ends are sealed properly with polyurethane sealant. Drill holes in the sill at a slight upward angle to avoid puncturing the bottom extrusion.
• Water Management: Proper management of water exiting weep holes must be designed and installed by others.

Suggested Typical Installation drawings are general and may not suit all installations. Product placement, fasteners, flashing, waterproofing, sealant, trim, and other details for specific conditions must be properly designed and provided by others.

Frame Assembly Steps

Step A6

Ensure proper flashing and waterproofing around the opening. Set the assembled frame into the rough opening, ensuring correct orientation for inward or outward opening. Refer to Diagram 2 for details.

Step A7 – Selection and Use of Installation Shims

Use only hard plastic ‘horseshoe’ style glazier’s shims; wood shims are NOT appropriate (Illustration A8). Install shims between the system frame and building structure at every fastener location to keep frame components straight, level, and plumb, without twisting.

Step A8

Stand up the assembled system frame and temporarily secure it to the rough opening with clamps. Position the frame in the rough opening. Use loose shim stacks at either end of the sill track to center the frame horizontally. Check for sufficient shim space behind side jambs to fasten them plumb and straight in Step A10 (Illustration A9).

Step A9

Place shims under the sill track at every fastener location to level the sill to within +/- 1 mm. Check sill track elevation relative to the finish floor level and anchor the sill with correct fasteners. Ensure screw heads fit within the head track and sill slots to avoid interfering with running carriages.

Check the fastened sill for levelness and ensure it is not tilted or twisted. Loosen fasteners and adjust shim stacks until the sill is at the correct elevation and perfectly level. Seal all drilled holes through the sill with exterior grade polyurethane sealant. Do not obstruct weep holes.

It is critical to make any necessary adjustments to level, plumb, and square before proceeding.

Step A10

Anchor the side jambs to studs or walls similarly. Ensure jambs are plumb and straight with no twist.

Step A11

Anchor the head track through pre-drilled holes, with shims above at every fastener. Ensure the head track is level (+/- 1 mm) and without tilt or twist.

IMPORTANT: Ensure shims are held firmly by frame screws, without bowing or twisting. Add or remove shims as necessary to keep frames straight, checking constantly for level, plumb, and square. Use a transit, rotary laser level, or similar equipment for these determinations.

Step A12

IMPORTANT: Ensure upper and lower tracks are clean and free of debris, especially drill cuttings. Use the angled brush if provided (Illustration A11).

B. PANELS AND FOLDING HARDWARE INSTALLATION

At least 2 people are needed to install panels. Use vacuum suction cups on cleaned glass surfaces to lift panels. Do not carry or lift panels by the frame, as this can move the frame out of its original position.

IMPORTANT: Look for glass stops to determine the interior side of a panel.

Step B1

Install hinge components on side jambs for panels hinged to side jambs. These are provided loose in the cardboard box. Review Diagram 3 for correct hinge component placement. Install with provided screws.

For top-hung SL60/o, insert upper running carriages into the top track through the slot on one end of the head track (Illustration B1).

For floor-supported SL60/u, proceed to Step B2.

Diagram 3: Side Jamb Hinge Placement

Diagram 3 illustrates hinge placement for inward and outward opening units, showing placement on upper and lower right/left jambs.

Step B2

Lubricate hinges with the provided lubricant spray. Ensure all hinge pins are completely inserted. Drive hinge pins only to the dome; the knurling should be inside the hinge barrel, with the smooth dome protruding.

Attach panel(s) to be hinged off side jambs by aligning hinges and inserting proper hinge pins. Ensure washers between hinge components remain securely in place (Illustration B2).

Step B3

Attach the next panel to create a folding pair by aligning hinges and inserting proper hinge pins. Use temporary blocks under panels if necessary for stability (Illustration B3).

Step B4

If additional panels are to be attached, close the pair by turning the handle between them to engage the shoot bolts.

Step B5

For top-hung SL60/o, attach the next panel by positioning and aligning the upper running carriage to the upper hinge components of the two panels, and inserting the provided bolt (Illustration B4). This bolt secures the assembly with a self-locking nut; ensure 1 full thread shows through, but do not overtighten.

Position the lower running carriage in the sill track. Align lower hinge components of the two panels with the lower running carriage and insert the proper hinge pin (Illustration B5).

For floor-supported SL60/u, follow the same procedure as shown in Illustration B6. The lower running carriage wheels ride on sill track inserts (Ill. A2), and two horizontal wheels guide inside the lower track. The upper running carriage guides in the upper track.

Step B6

For a running post at the end of an even number of panels or for paired panels, treat the running post like an additional panel for installation.

Step B7

Attach additional panels in the same manner.

C. FINAL STEPS

Step C1

Attach handles and other hardware not pre-attached. For lever handle sets on swing panels with multi-point locking hardware, install the profile cylinder into the locking gear and attach the set screw (Illustration C1). Cut set screw if needed (1-1/2" to 2" depending on lock type). For outswing units, attach pull handles between each pair of folding panels (Illustration C2). Close and lock all panels.

Step C2

IMPORTANT: For swing panels not attached to a side jamb, attach the panel catch to the top rail connected to the stile with the handle, and the catch counterpart to the opposite stile of the adjacent panel. Follow kit instructions. The swing panel must be opened and engaged into the panel catch before folding panels are opened (Illustration C3). Failure to install the panel catch can damage the system and void the warranty.

Step C3

Check operations and open the panels. Close and lock all panels into position (Illustration C4).

Step C4

Check all horizontal joints:

• Ensure head track and sill are level.
• For higher weather performance sill: check spacing between sill and each panel, and head track and each panel. Both spaces should be approx. 7/8" along the entire width of each panel.
• For flush and low profile saddle sill: spacing between sill and panel should be approx. 3/8" along the entire width of the unit. Refer to Diagram 2 for dimensions.
• Check if the upper corner of a panel with the running carriage is not higher than the other corner (slight lower, not more than 1/16", is acceptable). Proper spacing is critical.

If incorrect:

• For top-hung SL60/o, adjust upper running carriages +/- 1/8" by holding the bottom screw and turning the nut above it with a wrench.

Vertical Joints and Operation Checks

Step C5

Check all vertical joints (Illustration C6):

• Ensure side jambs are vertically straight.
• Vertical spacing between folding panels should be 3/8".
• Spacing at the meeting point of two swing panels with the side jamb should be 5/16".
• Spacing between the side jamb and a hinged panel should be about 1/2".
• Adjust hinges on the side jamb if necessary (+1/4", -3/16"). Loosen Allen screws (a) first, then Phillips screws (b) for top/bottom hinges. Retighten Allen screws.
• Further width adjustment can be achieved by adding/removing 1/16" shims along the entire height of side jambs and retightening fixing screws.

Step C6

If horizontal spacing is incorrect, adjust glass setting blocks bracing the glass. Remove gasket and glass vertical stops. Refer to Appendix B for setting block locations. Raise panel by increasing upper vertical setting block thickness; lower by decreasing it. Adjust lower vertical setting block accordingly. Use suction cups to raise glass for easier setting block placement.

Step C7

Check that the system operates and functions properly. Panels should move easily by one person (for up to 6 panels per side). Shoot bolts should engage smoothly. If panels do not move easily or require significant effort, the unit is likely not installed properly. Correct any problems before finishing.

Step C8

Finish waterproofing, flashing, trim, and sealant around the opening perimeter. IMPORTANT: Ensure weep holes in the sill are not blocked.

Step C9

Confirm panel catches are installed. Install appropriate door holders as needed to prevent uncontrolled movement of panels in the open position.

Protection of Unit During Construction Phase

Keep the unit closed, covered, and protected from damage during construction. Units are susceptible to damage from cement splatter, tar, paint, weld splatter, falling objects, dust, sand blasting, etc. Resist the temptation to use the large opening for ingress/egress by tradesmen.

Appendix A: FL Product Approval # 37263 Anchorage Requirements for the SL60 System

This product must be anchored as specified below:

NOTES:

• Fastener installations shown are capable of withstanding design wind pressures per Florida Evaluation Report for SL60 with safety factors.
• If rough opening is greater than 3/8", solid wood blocking must be provided.
• Inward opening details are shown. Outward opening panels require the same fasteners at the same spacings.
• Fasteners shown in the raised sill detail apply to all recessed type sills.
• All installation fasteners must have a washer under the head that bears on aluminum.

INSTALLATION FASTENERS:

• WOOD: #12 (0.216" diameter) x 4" wood screws, minimum 2 ¼" penetration.
• STEEL: #12 (0.216" diameter) x 2-1/2" self-drilling screws, minimum 0.593" (16 gage) substrate with minimum 2 ½" thick wood backing.
• MASONRY & CONCRETE: 1/4" diameter x 2-3/4" tapcons, minimum 1-1/4" embedment.

Drawings are not to scale.

Appendix B: Glass Installation and Glazing

This section applies if installing or adjusting glass setting blocks. Proper glass installation is critical as glass is a structural part of the NanaWall folding system.

Use glass stops and glazing gasket for “dry” glazing. Use hard plastic setting blocks with varying thickness; rubber setting blocks are not acceptable. Setting block width should be at least 1/8" wider than glass thickness and 1/16" to 1/8" less than glazing pocket width.

Glass must have appropriate dimensions, thickness, and specifications. Tempered glass is required unless the unit is a window placed above a certain height from the floor. Check applicable codes and regulations.

Float glass and insulated glass components must meet ASTM C 1306 and ASTM C 1048 standards, respectively. Tempered glass must have a permanent logo signifying safety compliance (16 CFR-1201, ANSI Z 97.1). Insulating Glass must meet ASTM E 774, Class A, B, or C.

While glass installation is straightforward, an experienced glazing contractor is recommended.

Bracing Direction and Setting Block Placement:

• Place setting blocks on opposite diagonal corners, alternating with each succeeding panel, for stability and balance. Incorrect bracing will affect proper operation.

General Bracing Rules:

• Panel attached to side jamb: Lower brace at the lower corner closest to the side.
• Panel with running carriage: Lower brace on the lower corner on the same side as the running carriage.
• Swing panel: Lower brace at the lower corner away from the stile with locking hardware. See Diagram 1 for examples.

Follow FGMA “Glazing Manual” and “Sealant Manual” recommendations. Use suction cups to move glass. Install glass on panels before installing panels in the opening, or lay panels flat on sawhorses. Glazing can be done after panel installation.

Glass Installation Steps:

1. Close all panels and secure with multiple point lock bolts. Start with a panel attached to a side jamb or closest to a side jamb in unhinged pairs.
2. Remove all glass stops, protecting the finish.
3. Measure vertical and horizontal dimensions of glass and panel opening. Calculate nominal thickness for setting blocks at top/bottom rails and stiles. Combine blocks if needed for desired thickness.
4. Place a setting block (or combination) on the bottom rail, approx. 2" from the bottom corner, per bracing rules.
5. Carefully place glass, resting on the setting block. Ensure even support for inner and outer panes of insulated glass.
6. Place a second setting block in the same corner, vertically along the stile, approx. 2" above the corner.
7. Place another setting block in the upper diagonal corner vertically on the opposite stile. Use non-damaging adhesive if needed to keep vertical blocks from slipping.
8. Place the last setting block on the upper rail, on the same corner as the other upper setting block. Shift glass weight to get a proper fit. Setting blocks should fit snugly but not be forced. Adjust block thickness so the panel is slightly out of square; the upper corner with blocks should be approx. 1/16" higher than the other corner. Additional blocks may be needed midpoint on stiles for large panels.
9. For aluminum systems, insert glass stops to snap into the panel profile. For wood systems, insert stops flush with the panel and nail to the inner side with small finish nails. Start with top/bottom stops, then sides.
10. Insert glazing gasket between glass and glass stop. Cut gasket slightly longer than the stop length, as it may shrink. Do not stretch. Use soapy water to lubricate if necessary.
11. Ensure stops are locked firmly and flush with the panel profile.
12. Repeat steps 2-12 for each panel. Ensure setting blocks are placed at diagonally opposite corners in the proper sequence.
13. After panel installation, check if the gap between the panel and head jamb/sill is even across the width. Glass weight may even out out-of-square panels. If the upper corner remains high, adjust setting block thickness. Panels must be braced correctly for proper operation.

Operation and Maintenance

Operation of a NanaWall Folding Unit

Observe special notes for opening and closing the folding system.

• Safety: Do not place fingers between panels/pivot points during operation. Do not allow untrained persons or children to operate the unit.
• Operation: Do not force the system if not operating properly; have it repaired by a qualified technician. Anchor panels when open to prevent uncontrolled movement, especially in windy conditions.
• Security & Weather Resistance: Keep the unit closed when not in use for best security and weather resistance. Engage all locking mechanisms fully when closed.
• Sequence: The correct sequence of opening and closing depends on the configuration. 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 locking points on all other panels.
3. Slide folding panels, starting with the pair adjacent to the swing panel.
4. For closing, proceed in reverse order.

Without a Swing Panel:

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

With Unhinged Paired Panels and No Swing Panel:

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

Operating the SL-Multipoint Locking on the Primary Swing Panel

• Engaging Locking Points: Turn handle up about 45° to engage locking rods, then let it return to normal position. The swing panel must be fully closed with locking rods engaged to seal properly. Lock with a key (outside) or thumb turn (inside).
• Disengaging Locking Points: Unlock with key or thumb turn. Operate door handle downwards to disengage top and bottom locking points.
• Check Lock: The door is locked when the handle cannot be depressed.

Recommended Maintenance of NanaWall Products

General Considerations:

1. Installation: Correct installation is crucial for proper function and to prevent premature failure. Panels should move easily by one person (except for very large panels or >6 panels per side). Locking points should engage smoothly. No rubbing on the floor or binding. Consistent reveal between panels and tracks when closed; no daylight visible. Correct problems promptly.
2. Adjustments: Due to building movement or temperature changes, adjustments by a qualified technician may be needed.
3. Operation: Operate locking points gently; do not force. Open and close panels in the proper sequence.
4. Component Check: Periodically check for worn/damaged components and replace them. Nonworking components increase stress and risk premature failure. Worn components compromise air/water infiltration, structural loading, and forced entry resistance.
5. Sealant/Caulking: Periodically inspect exterior perimeter sealant/caulking. Trim old caulk and seal gaps with quality caulk.
6. Weep Holes & Gaskets: Check weep holes are clean and clear of obstructions. Remove debris from tracks to prevent damage to running carriages and guide trolleys. Clean components and check gaskets for proper seating and condition.
7. Surface Maintenance: Clean aluminum or wood surfaces periodically. For aluminum, use warm soapy water; mineral spirits for stubborn stains. For wood, use water and a soft brush; mild detergent for heavier accumulations. Avoid aggressive cleaners and abrasive rubbing. Superficial damage to aluminum should be touched up immediately.
8. Wood Inspection: Visually inspect wood products every six months or as needed, depending on exposure. Repaint or restain as needed.
9. Hardware: Periodically clean hardware, hinges, and handles with a soft cloth and mild cleanser. Avoid abrasive rubbing. Oil-rubbed brass develops a unique patina.
10. Lubrication: Every six months, apply lubricant to hinges and Teflon spray to running carriages and guiding trolleys.

Specific Maintenance for Coastal Salt Water and Extreme Environments:

Environments within one mile of a seacoast are corrosive and can cause products to deteriorate faster.

• Weekly: Open/close unit completely, inspect surfaces. Ensure salt/abrasive materials are not built up. Keep sill and head jamb tracks free of dirt/debris. Ensure no standing water in the sill track. Verify all hardware is intact and operating properly.
• Monthly (or more frequently): Clean all surfaces with mild detergent soap and fresh water. Rinse thoroughly and allow to dry. Do not use abrasive cleaners or materials. Ensure glass cleaner does not run onto other surfaces.
• Repairs: Immediately repair any breaches in paint coating (scratches, chips, abrasion).
• 3-Month Maintenance: Clean and dry upper/lower rollers and hinges. Apply Teflon spray (no grease) to rollers/bearings. Oil hinges and hinge pins with light weight oil or Teflon spray. Do not use WD40. Use silicone spray for gaskets only.
• 6-Month Maintenance: Apply wax to the outside of painted panels and tracks, ensuring wax penetrates corner connections.
