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…).
Unpack each element before starting to assemble the staircase. Position the elements on an ample
surface and check their quality (TAB. 1: A = Code, B = Quality).
Assembly
1. Carefully measure the height from oor to oor.
2. Calculate the rise:
1) subtract 22 cm from the height measured from oor to oor,
2) divide by the number of rises minus one.
Example: for a height from oor to oor of 268 cm and a staircase with 12 rises;
(268 – 22) / (12 – 1) = 22.36.
3. Determine the position to x support N19 (g. 1) considering two points:
1) that the rise, previously calculated, also includes the thickness of the L73 tread (g. 2).
2) position support N19 taking into account the type of opening (g. 3).
4. Drill with a Ø 14 mm point.
5. Assemble supports N19, N18, N17 and N16 in a straight conguration on the oor, taking the rise
calculated before into account. Use elements C15, B71 and B75 (g. 1). Secure in an adequate
manner, considering that supports N19, N18, N17 and N16 must still rotate for conguration B.
6. Raise and position the structure keeping support N19 in contact with the oor (g. 4). If the bay
of the stairs is narrow, we recommend rotating a few supports.
7. Secure support N19 in a permanent manner, using element C39 (g. 1).
8. Determine at this point which is the rst step from the top. Drill L73 treads using the L74
cardboard cutout jig you nd in the package, alternating a right tread and a left tread (g. 3).
9. Decide where the railing will be assembled (internal or external) and drill the L73 treads using a Ø
6.5 mm bit, according to the measurements found on the drawings for each conguration (g. 3).
10. Assemble and secure elements F23 and F29 using elements C14, B83, C49, C13, B02 (g. 1).
11. Secure the L73 treads in a permanent manner starting from the top until you reach support N16,
using elements C57 (g. 1).
12. 1. Conguration A (straight) does not require further modications (g. 3).
2. Conguration B requires a 5 ° rotation (g. 3).
13. To rotate the supports by 5°, proceed as follows:
a. Using a pencil in the point of connection between the supports, trace two vertical lines at a
distance of 3.5 mm (g. 5).
b. Loosen elements C15, one support at the time, starting from the top and rotate until one line
coincides with the other.
c. Secure elements C15 in a permanent manner (g. 1).
Railing assembly
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. 6, Fig. 1, Fig. 1a);
assemble parts D43, C83, C54, BG1 and C77 on the CL9 baluster (Fig. 6, Fig.1). Caution: align the
holes in parts C63 and D43 with the holes in the CB6, CB7 and CL9 balusters (Fig. 6)
16. Insert the CB6 balusters into F23 elements, positioning C63 element with the open part towards
the top, locking them with element B02. Secure element F34 to the oor, next to the rst baluster
CL9 and drill using a Ø 8 mm bit. Use elements B12, B02, C58. Insert the CL9 baluster and
tighten element B02. Check the verticality of each baluster. Starting from the baluster at the top,
secure the A22 handrail (leave the amount of handrail required to secure baluster CB6, which
goes at the end and has not been inserted yet) using articles C64 and an electric screwdriver.
