WARNING: Carry out the installation in a "workmanlike" manner, strictly following the installation
instructions and using suitable tools. Always consult your local building department for code requirements
that must be respected depending on its destination of use (private, secondary, public...).
Before starting the assembly, unpack all the pieces of the staircase. Spread them out on a spacious
surface and check the number of pieces (TAB. 1: A = Code, B = Quantity).
Assembly
1. Carefully measure the height from floor to floor.
2. Calculate the value of the rise:
1) subtract 22 cm (8 5/8") from the value you obtained for the height from floor to floor,
2) divide this value by the number of risers, less one.
Example: for a height measured from floor to floor of 268 cm and a staircase with 12 risers;
(268 – 22) / (12 – 1) = 22,36 (8'3 1/2" – 8 5/8") / (12 – 1) = 8 3/4".
3. Determine the position in which to fix the N19 support (fig. 1) considering two points:
1) the riser, as previously calculated, also includes the thickness of the step L40 (fig.2).
2) position the N19 support considering the type of hole (fig. 3).
4. Drill the holes with a Ø 14 mm bit.
5. Assemble on the floor the N19, N18, N17 and N16 supports in a rectilinear configuration,
considering the riser previously calculated. Use components C15, B71 and B75 (fig. 1). Tighten
sufficiently, bearing in mind that the N19, N18, N17 and N16 supports must still be turned for the
B configuration.
6. Raise and position the structure with the N19 support in contact with the ceiling aperture (fig. 4).
Should the stair-well be tight, you are advised to turn some of the supports.
7. Permanently fix the N19 support, using component C39 (fig. 1).
8. Determine at this point which is the first step from the top. Drill L40 treads using the cardboard
cutout jig L41 you find in the package, alternating a right tread and a left tread (fig. 5).
9. Decide where to assemble the banister (inside or outside) and drill holes in the steps L40 with a
Ø 6,5 mm bit, in accordance with the measurements in the drawings for each configuration (fig. 3).
10. Assemble and fix the F29 components using components C14, B83, C49, C13 and B02 (fig. 1).
11. Permanently fix the steps L40, starting from the top and working downwards to support N16,
using components C57/C40 (fig. 1).
12. 1. Configuration A (rectilinear) does not require any further modifications (fig. 3).
2. Configuration B needs a 5 ° rotation (fig. 3).
13. To rotate the supports by 5° proceed as follows:
a. Trace with a pencil, at the point where the two supports meet, two vertical lines at a distance of
3,5 mm (fig. 6).
b. Loosen the C15 components, one support at a time, starting from the top and rotating them
until one line meets the other.
c. Permanently tighten the C15 components (fig. 1).
Assembly of the banister
14. Cut the balusters as described in the diagrams. The balusters at the ends, where the cut
measurement on the drawings cannot be seen, must be cut based on the slope of the railing for
the staircase, in other words after handrail A13 has been mounted.
15. Assemble parts C63, C65, C66, BG1, C77 and B82on the balusters CB6 (Fig. 7, Fig. 1); assemble
parts D43, C83, C54, BG1 and C77 on the CL9 baluster (Fig. 7, Fig.1).
