2 This manual is provided as part of our long-term commitment to a supportive, interactive relationship with our valued customers. It contains all the information needed to select, plan, install and maintain a modern raised floor system. In addition, the CHIC technical staff is always ready to answer any queries.

3 The Area Data Center design has jumped leaps in the last 10 years. Todays new designs require raised flooring to have higher specifications. Field areas, where equipment, batteries and cabinets are located, require heavy duty rated panels to address the static load of operational equipment. As new computer and communication technologies have revolutionized the workplace, means and methods for distributing services have likewise undergone significant advancements. CHIC modular raised floor system allows project planners to incorporate unlimited flexibility into the workplace, providing for virtually any type of future modification as well as unforeseen changes. The new technology reduce time and costs during the original construction phases, and becomes even more cost-effective over time due to it s ease of maintenance and durability. Given the increasing weight of equipment being placed on the raised access floor, CHIC floor system has been technically upgraded and aesthetically improved to meet today s requirement. The CHIC system offers the STR under structure pedestal for this specific type of installation i.e. switches and data centres, as well as tiles available in the widest selection of top finishes with different cores to cater for specific uses.

5 STR ACCESS FLOORING SYSTEM Electro-galvanized understructure up to 1000mm FFH. STC is engineered to bear heavy loads with adjustable pedestals made of pressed galvanized steel with height adjustment range from 85 mm to 1000 mm. The pedestals are set in links with a distance of 600 x 600 mm and are composed of: Base: The round base which has a diameter of 95 mm (thickness of 1,5 mm) and/or 100 mm (thickness of 2,5 mm) according to the spec height of the M16 welded, threaded shaft. The height level is blocked with a 6-toggle nut. Head: Supporting element composed of a metal plate 75 x 75 mm, 2.5 mm thick, shaped by shear die to achieve besides the necessary stiffening effect and supports include a deep drawing so that a complete object suitable for adjustment can be produced in a single piece,. This state-of-the-art solution makes welds and forced couplings unnecessary. This also guarantees natural rigidity and perfect coupling with the other element of the pedestal. A gasket of antistatic polythene, completes the head and snaps on to become solid with it. Stringer:The STR stringer is a load-bearing stringer with a ribbed Omega section profile, 21 x 33 x 1 mm and 554 mm long, with anti-cut fold (an accident prevention device to comply with 626/494). Like the other types it is made by press-folding 1 mm thick sheet metal to produce an object with maximum rigidity and precision. The stringer snaps onto the head and thus fits exactly even without the anchorage screw which is nonetheless available. All the stringers are supplied with antistatic polythene gaskets, to seal and soundproof them. Stringers allow rapid installation.

6 PT40 Description: Modular panel composed of wood-core particles bound together by heat hardener resins and obtained with a continuous process of thermo-pressing so as to guarantee high homogeneity of mechanical characteristics and dimensional stability. Top Finishes: HPL Laminate, PVC, Porcelain and or re-constructed stones with antistatic coating. Bottom Finishes: Aluminium Sheet - 0,05mm aluminium sheet that guarantees an excellent barrier against humidity, fire and electrical continuity to the floor. Laminate - Phenolic laminate sheet that improves the rigidity of the panel, its mechanical characteristics and it constitutes a barrier against humidity. Steel tray/steel sheet - 0,5 mm galvanized steel plate that protects the panel from humidity, fire and ensures the electrical continuity of the floor as well as improving the rigidity of the panel and its mechanical characteristics. Edge: ABS Protective material in similar color as top finish for minimal joint effect.

8 Storage And Installation. Storage 1. The rooms where Raised Floors will be stored and/or installed, must be dry, waterproof with effective weather seals at windows and doors. 2. The temperature level of the rooms must be between 5 and 35 C (40-95 F) and the humidity rate between 40% and 75% 3. In case storage by the job site is not possible directly in the rooms where the Raised Floors are to be installed, it is recommended to store them in the nearest rooms offering temperature and humidity conditions as specified above. Installation Once preparations have been made as outlined in the previous section, it is possible to begin laying out the structure of the panels. Before taking any action, it is strictly necessary to check the difference in level of the slab, since the standard pedestals have an average height adjustment range of 30mm, but often slabs present greater differences in level. Moreover, after the cleaning up of the dust from the slab, it is recommended to use an anti-dust treatment product such as a poliurethan or epoxy paint. This treatment is indispensable if the space between the slab and the panels is used as air-conditioning channel (plenum). 1. The first step in laying out the job, is the tracing of two perpendicular axes inside the room, using a non-stretch measuring tape (check the perpendicularity of the two axes by the Pyithagorean theorem: the sum of the squares of two sides of a right-angle triangle is equal to the square of the hypothenuse. See Fig.1: 2. After that, the pedestals are to be placed according to the modular nest 600x600 mm, starting from point 0 (Fig. 1). If, by following this module, two cuts of different sizes are obtained at the wall (perimetral cuts) - i.e. 50 cm and 20 cm -, it is recommended to avoid having excessively small panel cut pieces at the sides of the room. Fig. 2: 3. Once finished with the laying of the structure (pedestals and stringers, if required), the pedestals are best adjusted by using a laser-self-levelling device (an optical transit is a suitable alternative).

9 4. Then, the first panels can be laid, as to form a T-shape starting from the first internal line on the two perpendicular axes, fig. 3: 5. After that, the squarenes of the layout must be checked (fig. 3): A = ml 3,60, B = ml 4,80 C = ml 6, Then the laying of the panels can go on progressively in the two directions opposite to the T-shape (fig. 3). 7. The last panels to be laid form the perimeter, after being cut to size. If stringers are not required, the pedestals are to be fixed to the slab by gluing. In this case pedestals and panels are laid at the same time, adjusted and levelled one at a time. At the end, before being able to walk on this Raised Floor, one must wait 48 hours to allow the glue which fixes the pedestals, to fully cure. Finally, it is recommended to protect the top finish with cardboard or polyethylene sheets until the furnishing and set-up of the room is finished.

11 Use And Maintenance The raised floor is composed of many removable elements. The panels, which form the walking surface are laid one beside the other; consequently, the stability of the system must be guaranteed by following some simple maintenance guidelines: 1. When using lifting trucks to move heavy loads, lay some stiff material such as plywood on top of the panels to help distribute the loads. 2. If you have to remove some panels, it is better to avoid the formation of "isles" or "long channels", by removing only the minimum number necessary to reach the objective. Re-install the panels one-by-one in the reverse order in which they were removed. 3. Be careful not to damage or to move the seals of the pedestals and of the stringers. Replace any damaged seals. 4. The removal and replacement of the panels must only be done by utilizing the appropriate lifting tools. 5. Take particular care, in moving panels containing accessories (grids, electric systems, etc.) in order not to damage the connections. 6. When replacing partial panels, such as those at perimeter locations, it is necessary to be careful to place them again in their original position.
