6. INSTALLATION OF THE PRODUCTS
   6.1. The Product is not intended to be installed independently by the Customer. The installation of the Product must be carried out by a professional and experienced construction carpenter who, in addition to the necessary skills and tools, has full knowledge of the requirements and standards applicable to stair installation at the location of the project, and who complies with the installation instructions provided. [2].
   6.2. The staircase and railings are fixed to the building’s structural elements. In order to ensure the safe installation of the railings, the fixing points in lightweight walls must have underlying load-bearing structures of sufficient capacity or appropriately reinforced wall structures. A single layer of gypsum board will not be considered a suitable fixing surface.
   6.3. In the event that the Customer orders installation services for the Product from the Manufacturer, the Customer undertakes to ensure:
   ● access to the site must be ensured, as well as parking for the installer’s vehicle without additional costs;
   ● a safe working area must be ensured at the site;
   ● prior to the installation of the staircase, the entire stair opening must be cleared;
   ● floors on the site that remain within the work area must be covered to prevent damage (unless floor protection has been ordered together with the installation service). The Manufacturer is not liable for any damage resulting from uncovered flooring;
   ● sufficient space for the storage of tools and staircase components must be ensured on the site (the size of the area is agreed during the site measurement).
   6.4. If the Customer has not ordered the installation service, the Customer is responsible for the subsequent disposal of the packaging materials.
   6.5. The Customer acknowledges and accepts that the installation of the staircase may cause minor damage to finished walls. Repair of such damage is not included in the staircase installation service, and the Manufacturer is not responsible for repairing or compensating for such damage.
   6.6. Any work not specified in the Order Confirmation is not included in the standard staircase installation package. This includes, but is not limited to, the following works:
   ● covering of staircase treads;
   ● clearing of the work area and covering of floors;
   ● covering the edge of the intermediate floor slab with trim;
   ● covering the joint between the top step and the floor;
   ● removal or installation of various railing trims.

6.7. During installation of the staircase, a minimum gap of 3 mm will be left between the wall and the staircase structure. If the stair opening is not square or the walls are uneven, the actual gap may differ from the planned gap. If the Customer does not ensure the required construction and technical conditions, the Customer bears full responsibility for any resulting defects or deficiencies.
6.8. If the Customer has not provided accurate information in advance regarding the location of utilities concealed within walls and floors (including, but not limited to, electrical wiring, plumbing, and heating systems), the Manufacturer is not liable for any damage to such utilities that may occur during the installation works.
6.9. If, at the Customer’s request, the staircase is installed in unheated and/or excessively humid premises (relative humidity exceeding 65%, temperature outside the range of +10°C to +30°C, or relative humidity outside the range of 25–65%), or in premises where construction works causing excessive moisture will subsequently be carried out, a corresponding note will be made in the work acceptance report. By signing the report, the Customer confirms that they have reviewed the Order Terms and Conditions and are aware of the limitations set out in the Manufacturer’s warranty conditions.
6.10. The staircase installation price is calculated on the basis that the work will be completed in a single installation visit (or, in the case of larger projects, in the number of installation visits agreed separately). If, due to circumstances at the site, the work cannot be completed during a single visit and an additional installation visit is required, the Customer will be invoiced for the additional work on a time-and-materials basis.
6.11. If the staircase is installed by the Customer and defects and/or deficiencies are discovered in the packaged Products during installation, where the packaging showed no visible signs of damage (i.e. the defects could not reasonably have been identified at the time of delivery of the packaged Products), the Customer is required to document the issue and provide photographic evidence immediately upon unpacking and, in any event, before the Products are installed.
6.12. The completed works are accepted by the Customer or the Customer’s representative, and a Work Acceptance Report is signed for this purpose. If the Customer or the Customer’s representative does not attend the site upon completion of the works, the works are deemed accepted by the Customer. No subsequent claims regarding mechanical damage to the Product or the site will be accepted.
6.13. If any defects are identified, a corresponding note will be made in the Work Acceptance Report, and the defects will be remedied by the Manufacturer within a reasonable period of time.

7. PRODUCT QUALITY ASSESSMENT AND PERMISSIBLE TOLERANCES
7.1. The functionality of the staircase is assessed by walking up and down the staircase along the line of travel.
7.2. The visible quality of the staircase components is assessed by visual inspection from a distance of 2 metres.
7.3. Quality is assessed under the light of a 60 W incandescent bulb without a reflector.
7.4. The screw holes required for securing the staircase are not standardized, and their locations depend on the conditions and constraints of the installation site.
7.5. If heat sources or sources of moisture are located beneath the staircase, the Manufacturer is not liable for any damage resulting from movement of the wooden materials used in the staircase components.
7.6. Permissible tolerances:
● the colour tone of natural wood may change over time;
● slight colour variations in stained or lacquered components resulting from differences in the wood grain and texture;
● minor touch-up finishing work carried out during installation; slight differences in gloss level compared to the factory finish may occur. The result is assessed by visual inspection from a distance of 2 metres;
● structural variations inherent to natural wood, as well as minor cracks caused by changes in ambient humidity and slight noise when stepping on the treads;
● minor cracks in staircase components wider than 400 mm (e.g. staircase landings), resulting from the natural characteristics of wood;
● for oak and ash wood components, cracks up to 30 mm in length and up to 3 mm in depth.
7.7. Wood is a natural material and may exhibit variations in grain pattern, texture, and colour. The Manufacturer does not guarantee that one Product will be identical in all respects to another Product.
7.8. Permissible tolerances:

Staircase component / type of deviation	Permissible tolerance
Tread width	±3 mm
Overall riser height	±2 mm
First riser height	± 15 mm
Last riser height	+5 mm -10 mm
Longitudinal slope of tread	5 %
