User guideline NORTEC sonicNRSB-09

Issued by: PM Floor Division 10.6.09 Page 1 of 6 Rev.00NRBS-09

Dear Sir or Madam,

You have decided on purchasing a raised floor of the Lindner AG. We ask you to observe thefollowing instructions in order to guarantee an acceptable functioning of this system floor for thelong term after its installation in a professional fashion. This user guideline refers to raised floorpanels type NORTEC sonic.1 Climatic conditions

The room temperature should range between 15 oC and 25 oC at most. The relativeair humidity should range between 40 und 65 %.

Any change in the climate beyond the specified tolerances will cause a swelling orshrinking of the floor system according to the material used.

2 Opening and closing of the floor system

If panels are taken out of the floor area or channels for later installation works or similar, ithas to be paid attention to that this is done like it is shown in the following illustration.Free-standing pedestals which are not supporting at least one panel have to be avoided.

Exemplary proposal for opening the raised floor:The forming of islands has to be avoided. Do not take out more than 3 panelsout of one row.

Taken out panels shall be stacked in a way that visible side is applied to visible side andreverse side to reverse side so as to avoid any eventual smearing of the batch identificationon the covering side.



Horizontal forces are only permissible as partial forces of the loading allowed. The loadingspecifications refer to the closed raised floor. So do not carry out any transports towards anopen row of panels.

The raised floor panels may only be lifted with a suited lifting device.

The system may only be opened or closed by qualified personnel.

2.1 Taking out of a panel

NORTEC sonic with covered perforation (textile covering)

Place the spike lifter in the centre of the paneledge with a short distance to the edge of

approximately 5 cm and lift the panel slightly toloosen it and then remove the lifting device

again.

Then place the spike lifter in the middle of thepanel and lift it vertically.



NORTEC sonic with visible perforation

Place the lifting device in a ventilation hole inthe centre of the panel edge and lift the panelslightly to loosen it and then remove the lifting

device again.

Then place the lifting device in a ventilationhole at the middle of the outer edge on the leftand right side of the panel and lift it vertically.

2.2 Inserting of panel

NORTEC sonic with covered perforation (textile covering)

Place the lifting device on one side, hold thepanel with your hands, lay it with one side on twopedestals and push it to the neighbouring panel.

Lower the panel with the lifting device. If with theuse of a velour covering, the first row of the pilesof the adjacent panel is pinched in, the proper,

original state can be restored by “lifting” theinserted panel a bit.



NORTEC sonic with visible perforation

Place the lifting device on one side in one of theventilation holes in the middle of the outer edge

of the panel, hold the panel with your hands, lay itwith one side on two pedestals and push it to the

neighbouring panel.

Lower the panel with the lifting device.

Attention

Never put your fingers in the gap between the panels with the opening and closing of thesystem – danger of injury! (Illustration B)

Do never try to take up panels with unsuited tools like a screwdriver or a chisel (IllustrationC), as the panel edges can be damaged irreparably by this.

Detach the lifting device immediately after the use. Do not put taken out panels down on the panel edge.

Illustration B Illustration C

Basically: - Remove dirt of pedestal head.- Test if the gasket and eventually the stringers rest on the pedestal

head properly. - Check the installation direction of the covering.

Taken out panels shall be put back in their original positions and shall not be turned aroundinto a different position. Special attention has to be paid to the covering direction with



textile coverings. The panels are therefore labelled with an arrow. In addition, it has to bechecked whether they fit well and only then the next panel can be inserted.

3 Substructure

No pedestals, stringers, bridgings or other substructures may be altered. If in exceptionalcircumstances, such as for subsequent installations, it becomes necessary to dismantleany components, then the raised floor system may not be loaded. Non-compliance mightresult in the danger of a collapse of the system! System components which have beendismantled have to be remounted when the work is completed so that the vertical loadremoval and the horizontal rigidity are again assured.

4 Cable installation

Do not draw in cables over the edge of the floor system or a panel. Do not pull off ordamage pedestals through overstraining with the installation of cables in the cavity. Goodidea: Lay cables in from the roll.

5 Protective measures

5.1 Extraordinary loading

The floor has to be covered with planks, chipboards or steel plates with the transport ofheavy loads. The floor covering and the gluing is protected this way and the loads aredistributed to a larger area on the floor system.

Dynamic loads from lifting carts, forklifts etc. may not be included in calculations by simplytransferring the wheel loads to static loads. In such cases the DIN 1055 as well as themaximum permissible loads of our raised flooring systems have to be observed.

The tests and the classification are made according to current standards. The permissibleload indention points are defined in the application guideline to the DIN EN 12 825.



5.2 Continuous contact with waterContinuous contact with water has to be avoided absolutely as this leads inevitably to adamaging of the floor system.Water-tight saucers have to be used with plant tops and trays.

6 Cleaning and maintenance instructions

Basic principles conditional to the system have to be considered for the cleaning andmaintenance of the floor coverings on system floors. A soaking of the floor is generally tobe avoided as with moisture-intense cleaning, there is the danger of swelling, corrosion,delamination of coverings and the damaging of sensitive installations (e.g. smokedetector). Spilled water has to be taken up immediately with a cloth. Also with spilled liquidsare the contaminated resp. concerned panels to be taken out and cleaned.

Cleaning of textile coverings:

Dusting by vacuuming or vacuum brushes.

Cleaning of hard / elastic coverings – visible perforation

The floor system should only be cleaned and maintained slightly damp. Thecleaning devices like a mop or similar may not release mopping water resp. careemulsion into the perforation holes.

The cleaning water can penetrate into the perforation with the use of wet cleaningmachines. This has to be avoided absolutely.

Generally, an overwatering, too much spraying with cleaning agents as well asthe brushing with the cleaning and care agent is to be avoided. The superfluouswater will be taken up by the panel with the penetration of humidity into theperforation and therefore we can not guarantee the assured static valuesanymore. The humidity can as well saponify the covering glue which leads to adetachment of the covering.

Residues of the dirty water can also form up on the underside of the panel withoverwatering which can lead to the formation of mould fungus.

You find further information in the cleaning and maintenance instructions of themanufacturer of the covering.

Should you have any further questions, however, we are gladly available to provide you with any information.Telephone +49 (0) 87 23 / 20-26 51 Product Management Flooring Systems
