Installation InstructionsStep 1: Layout and Drilling

Once verification of the proper quantity and type of product has been made, the next step is to layout and drill the floor and/or risers following the seating layout drawing supplied by Irwin Seating Company’s Seating Layout Department. The profile drawings (Figure 1) may be used as a general guideline for riser restrictions and clearances; however, the profile drawings in Figure 1 are always superseded by the layout drawing for project specific applications

The drilling pattern(Figure 2) may be used as a general guideline for installing low, high-rise, and super high-rise standards, however may be superseded by the seating layout drawing for project specific applications.

Left and Right fixing points are for normal use (capacity of anchors is spread more evenly and access for tightening is easier). Top and Bottom hardware only need to be used if re-bar is encountered or edge distance is a concern.

Note: Do not torque down primary hardware until rail clamp hardware is tight, this makes it easier to fit rail and allows clamp hardware to be tightened square to rail.

Marking out Drilling/Stanchion Positions

1. Check that all drawings match physical site measurements (overall row widths) – Any differences need to be checked with client ASAP to resolve possible revised seat count/seating plan.

2. Use formula A if you need to calculate the number of stanchions per row (This is normally specified on the seating layout prior to job commencing).

Length of row - 18”

Formula A: 41 3/8” (Max) = Qty of stanchions

3. If the amount of stanchions is a broken number round it up. E.g. 11.277 will be 12 stanchions. Chair to stanchion ratio never to exceed 2 chairs:1 stanchion.

4. Mark end stanchions (center of the stanchion) 9” from edge, step or wall (Figure 4, p.6). This can be increased to 11 3/4“ Max in exceptional situations.

5. Use formula B if you need to calculate the exact spacing between stanchions (This is normally specified on the seating layout prior to job commencing). Maximum allowable span between stanchions = 41 3/8”.

Length of row - 18”

Formula B: Qty of stanchions (step 3) = Spacing between stanchions

6. Where ascending rows are equal in length (straight rows), only mark out the stanchion positions of the very top and bottom rows and line up all other rows in-between. First and last stanchion positions at 9” from end of row, the rest of the stanchions according to the spacing calculated in (step five, Formula B). String a line between the stanchion center positions on these two rows and mark out the rest clearly (Figure 5, p.6).

7. In curved/segmented areas greater than 10 degrees, brackets should be placed at a minimum of 19 11/16” away from the apex. Stanchions then need to be spaced out evenly until the end of row or next apex.

Figure 3: Stanchion spacing for bent rail.

8. Standard rail will flex enough to be installed in apexes of <15°. “Flex-rail” is to be used for apexes of 15°-25°.

9. Optional; a cover-meter can be used to check for reinforcement-bar under the drill location markings, where an-chors will be installed. Although not 100% accurate, this can be useful in some cases. If re-bar is detected, the fixing locations can be shifted sideways by up to 3/4”, without having to adjust the overall row spacing.


11-2012


Figure 4: The first and last stanchion of a row should be placed 9” away from the step, with a 41 3/8” maximum distance between stanchions after that. Make sure to have an equal spacing between all stanchions.

Figure 5: To ensure a visually consistent run of chairs, set an anchor at the beginning and at the end of the row. Use the anchors to snap a chalk line to follow for drilling anchor locations in accordance with the seating layout draw-ing. The drill pattern is used to mark drill holes along the chalk line at the appropriate chair spacing.

Drilling1. Check the correct drilling height according to section drawing for riser (wall) mounted stanchions. Check offset

from riser for tread mounted stanchions.

2. When using the standard 3/8X3 (Hilti Kwik Bolt 3 Wedge Anchor), 2” minimum of embedment depth is required.

3. Set depth on drill jig to allow minimum required embedment depth. Edge distance requirement - drilling close to another hole/crack/cavity/end of slab will potentially lead to anchor failure. Minimum edge distance is 2 1/2” should be maintened during the installation.For riser-mounted brackets, where an exceptional load is to be supported such as at a building movement joint where there is an unavoidable rail overhang, brackets should be mounted with 3 anchors to give greater support. Concrete weaker than 18.4 ft-lb should be tested for edge distance strength. Do not exceed anchor manufacturers minimum edge distance of 2 1/2”.

Figure 6: Anchor placement for 3 anchor setup

Note: If the drill bit sinks in too easily, a pocket in the concrete might be responsible. The hardware won’t work and the location needs to be shifted over sideways by the minimum edge distance and re-drilled.

4. Make sure that the center line on the riser face is exactly in the middle of the drill bits before turning the handle.

5. Blow dust out of drilled holes with a hand pump.

6. Trial three sets of holes and check hole depth / stud height – by installing a bracket and tightening properly.

7. Trial a few stanchions with rail and chairs on to check the final fit (seat height, walk way clearance etc.) before drilling a complete area. Confirm with Site Manager.

8. Sweep up treads before next stage of installation commences.

Note: Change out drill bits after every 100 holes. This might need to be done more frequently with harder concrete.

Anchor Installation:1. Hammer drill a hole the same nominal diameter as the anchor bolt2. Clean hole of all debris.3. Push anchors in holes (do not hammer down), then place the stanchions on top of the anchors. 4. Drive the anchor far enough into the hole so that at least six threads are showing above the standard.

Installation InstructionsStep 2: Installation of Stanchions/Rails

Stanchion Brackets, Rail and Connectors:

1. Cut the rail to required lengths (specified on the seating layout) with a chop saw, always making sure both ends are supported for a square cut.

2. Rail joining:Using 2 joiner pieces per joint, secure them in place halfway through the front side with 4 rivets (AD44ABS) either side of a joint per piece (8 rivets total per joint). Do not use past the last stanchion on a row so that chair is half hanging over a connection (Figure 7).

Note: Use No.10 size drill bit when drilling rail and connectors for joining.

Note: Rail connectors are not used on Flex Rail.

Figure 7: Rail connectors are only to be used on lengths where 3 or more stanchions are in use.Note: Off-cut lengths to attach to rail should be longer than 19 9/16” long and must not overhang the last

stanchion in row.

Figure 8: Rail connector locationing rules3. Place total beam length loosely in stanchion clamps with ascending row ends lined up, using a string-line.


11-2012


Figure 9: Engagement of clamps to rail lip is critical to the function and safety of the system, failure to ensure clamps are correctly fitted could result in injury.

4. Tighten rail to stanchions by using an impact driver or hand socket (Use of a Hilti SI-100 is recommended), ensuring both clamp sets are correctly engaged with the rail (Figure 9). The torque setting for M10 rail clamp fixing is 33.2 ft - lb.

5. Tighten up all anchors in a row after the rail has been clamped in. The torque setting for 3/8X3 anchors is 20 ft-lb.

Note: The rail height must be 13” from the floor to the top of the rail in order for the seat height to be cor-rect, failure to do so will result in chairs that are too short.

6. Stack left-over aluminium for use on next row or recycling.

7. Taking care to not damage the rail end cap, knock a cap onto the ends of each rail (Figure 10, p.11). Once the cap is in place, secure by drilling a hole (#41 drill size) in the front side of the cap and rail and riveting (AD-34ABS) it in place (Figure 11, p.11).

8. Repair unused holes in structure by patching up with pre-mixed concrete.

Note: Sweep up aluminium filings/ dust before bringing any chairs to the area.

Note: Ensure all rail/ stanchion hardware is tight before fitting any chairs.

Installing Flex Rail

1. Remove joggle clamps from inner two stanchions; loosen the joggle clamps on the outer two stanchions.

2. Set Flex rail in outer stanchions, making sure to center the rail between the two outer stanchions.

3. Tighten the outer two stanchions to a “snug” fit.

4. Attach the rail vice to one of the inner stanchions by attaching the end of the rail vice to the stanchion using the pn that comes with the rail vice. (Figure 12)

Disassemble the Stanchion Clamp Attach Rail Vice to Stanchion

Figure 12: Attaching the Rail VIce to the disassemgled Stanchion 5. Drive the lead screw halfway, then re “snug” the outer clamps.

6. Drive the lead screw the rest of the way and attach the fourth clamp to the stanchion.

7. Torque all three of the fully assembled stanchions to 33.2 ft-lb.

8. Remove the rail vice from the stanchion it’s attached to, and assemble the last clamp, torqueing it appropriately.

9. Once rail is fully assembled and torqued in place, secure the bend by attaching a #1/4X112TEK screw every two feet of the flex rail. (Figure 13)

Top Side

Front Side

Figure 13: TEK Screw LocationNote: #1/4X112TEK screws should be attached so that they do not interfere with attaching chairs, for this reason, place them on the lower half of the flex rail.

Note: Do not attempt to uninstall flex rail. If uninstallation is needed, contact ISC’s CTS department.

Installation InstructionsStep 3: Installation of Chairs

Chair Modules and Rail Mounted Arms:

1. Check layout drawings for how many chairs and of which type & color are required on every row and/or area to be installed.

2. Start at the row ends – place first & last chairs 3/8” from the rail ends. If the installation includes armrests this is to be increased to 5/8” (Mark 3/8 or 5/8” on all rail beam ends before fitting chairs).

Note: When placing the end chairs; line up the mark on the rail with the badge of the chair.

Mark on Rail

Figure 14: End Spacing 3. Mark out the center of each row on all the rail beams clearly, but on a hidden surface (back of rail).

4. (a) Place a chair either side of center marking if the row has an even number of chairs.

(b) Place a chair centered over center marking if the row has uneven number of chairs.

5. (a) On straight rows with equal rail lengths: Set required number of chairs (and armrests) loosely on the rail, in between the end and middle chairs (or armrests), space the top and bottom rows out evenly and string line in between for all other rows.

(b) On straight rows with different rail lengths: line up the middle, then end chairs (or armrests) and space out evenly on every individual rail beam to fit the required number of chairs (and armrests). Use string line to line up all rows in between top and bottom rows.

(c) On curved areas – Set required number of chairs (and armrests) loosely on the rail, in between the end and middle chairs (or armrests), and space out evenly for every row individually.

Note: Once the spacing has been confirmed by setting up two chairs to the correct spacing (called out on the seating layout), you can measure between the two chairs to build a shim for spacing the rest of the row.

Care & Maintenance

Performance CheckFixed seating should be inspected periodically to ensure the chairs are in safe, working condition. Inspection should be performed every six months, heavy use facilities may require weekly inspection. Any chair that is found to be damaged should be taken out of service.

It is required that a regular schedule be developed based on the frequency of use and the degree to which patrons use the seating in ways other than which it is intended for.

Performance Checks should include all aspects of the chair including those not listed specifically here.

Back Inspection:• Check to make sure the back is secured to the arm stanchions.• Inspect the back for damage from vandalism.• Inspect the upholstery for wear.

Seat Inspection:• Oscillate each seat to make sure it returns to the upright position under its own power.• Check to make sure the seat is secured to the chair arm stanchions.• Inspect the seat for damage from vandalism.• Inspect the upholstery for wear.

Stanchions and Armrests:• Check to make sure stanchions are secure to the anchors / screws. • Inspect the rail, chair clamp, armrest support for damage from vandalism.• Inspect armrests to ensure they are secured and that they have not been damaged from vandalism that will

harm a patron.

Accessories:• Inspect all accessories (letter & seat plates, aisle lights, cup holders, etc.) to ensure they are secure and in

proper working order.

Should any component be found to not be working as originally installed remove the chair from service if the problem creates a safety issue. Refer to the components maintenance instructions for instructions on how to repair the chair. If you are unsure how to repair a problem please contact the Irwin Seating Company Customer Technical Services Department by calling 1.866.464.7946, Mon. - Fri., 8:00 am - 4:30 pm EST.

Parts may be ordered by contacting your local Irwin Seating Company Parts Department, by calling 1.866.464.7946 or visiting www.irwinseating.com.

Step 4: Final Check and Installation Review1. Make sure all the hardware is tight by rocking the chairs back and forth.2. Make sure all rows have end caps and relevant furnishings.3. Check that all chairs tip-up automatically by pulling seat down and making sure it rises fully. 4. Check that all the hardware on chairs is in place and does not have sharp edges.5. Make sure that the seats do not have any scratches, marks or stains.6. Aluminium and cardboard can be recycled.
