ASSEMBLY INSTRUCTIONS
In order to assemble the staircase with the greatest possible ease, we advise you to begin the installation with all the necessary equipment on
hand. Remove all the parts of the staircase from the packaging and lay them on a large surface so that they are all visible.
Key: L = width A = rise HT = total height
All dimensions are given in centimetres.
STAIRCASE ASSEMBLY:
1) Calculation of the rise (A)
Measure the height from the starting floor to the stair end landing floor HT (Fig.1). Subtract the value of the first fixed rise 21 from the total
height then divide the result obtained by the total number of steps, bearing in mind that the stair always finishes below the floor level.
The value obtained must always be between 20 and 24 cm.
Example: (280-21) = 259 (259:11) = 23.5
2) Calculation of staircase dimensions
For the overall dimensions of the stair, consult the tables with the dimension drawings (page 20).
3) Fixing of the staircase to the slab
Define the position of the landing support on the slab, respecting the rise A, previously calculated ensuring a good leveling of the step (Fig.2).
Drill correspondently to the holes in the plate with a Ø 14 mm drill and block the support to the slab using the proper expansion. In the case of
wooden floor/slab use only screws for wood, of the hanger bolt/leg bolt type, to replace those provided.
4) Assembly of the structure components
Once having fixed of the landing support, assemble the next intermediate module to it, in correspondence with the holes using the appropriate
screws and washers. Before securing the supports completely, adjust the rise by sliding the part vertically. Carry out a spacer equal to the
measure of the rise to place the modules of the structure quickly without errors. Proceed in the same way with all the remaining intermediate
modules, then insert the plastic closure cap into each one (Fig.3). Place a provisional prop half way up the flight with a support post.
(N.B.: Pay close attention when fitting the modules to ensure that they are perfectly aligned).
5) Fixing of the staircase to the floor
Complete the assembly of the supports till the starting module, ensuring that the staircase has been precisely positioned with respect to the
stair well, then mark out the points for fixing the plate to the floor. Drill holes using a Ø 14 mm bit and fix the starting module to the previous
intermediate module, then securing the plate to the ground using the appropriate expanding tie-rods. (Fig.3). In the case of wooden floor / slab
use only screws for wood, of the hanger bolt / leg bolt type, to replace those provided.
6) Fixing of the steps
Define the exact sequence of the steps, taking into consideration that the steps alternate. (For the staircase's exact configuration, refer to the
diagrams shown on page 19). Use the paper template supplied to make holes in the steps for the fixing of the modules in correspondence with
the bushes as shown in (Fig.4). Fix the steps to the supports using the self-threading screws in correspondence with the holes made (Fig.5).
N.B.: Fix to the wall the step bracket in the middle of the flight, in order to make the stair stiff (Fig. 5a).
7) Mounting the platform (optional accessory)
For making the holes for a platform (if present), use the same template as the straight step, referring to the previous shaped part. (Fig.6). First
assemble the landing module with an intermediate module in order to make the complete landing structure (Fig.7). Tighten the bushes
platform, then fix to the staircase structure. The platform cannot be placed at the starting or landing point of the staircase.
N.B.: Orientate the components of the landing structure according to the sense of climbing of the stair.
Position the platform above the structure in correspondence with the previously made holes, then trace out and drill holes using the other 4
bushes as a reference point. Fix both step and structure using the appropriate self-threading screws (Fig.8). The landing bracket is used to
support the staircase when the landing changes direction (Fig.9).
RAILING ASSEMBLY:
N.B.: The stair has to be always assembled with the railing or with the little supports; the steps can't never be "free".
8) Punching of steps and fixing the pawls
For a correct positioning of the handrail, refer to the diagrams shown in (Fig.10), where the positions of the columns are shown.
The punching on the steps for fixing the railing must be carried out using the previously cut paper template, following the indications shown in
(Fig.11). N.B.: On the landing step, position the punching closest to the floor, 2mm further towards the step so that there are 22mm from the
edge of the step to the punched hole (not 20 as normal punching carried out using the template would produce) (Fig.12).
IMPORTANT! Once the position for the pawl screw has been defined on the step, make a hole using a Ø 4 mm bit with a depth of 3-4 cm
(Fig.13). The pawl of the landing is fixed on an axis to the pawls components of the previous and next steps.
9) Fixing of the balusters
Attach the "cima" connectors with its various components to all balusters as shown in (Fig.14).
Starting from the bottom, provisionally position the first, the second and the third balusters inserting them into the pawls components, ensuring
that the second and the third balusters are flush with the underside of the step. Height X measured between the second and the third baluster
determines the measurement to which the first baluster must be cut (Fig.15), which will then be fixed to the floor using the bells (Fig.16).
Secure the balusters using the appropriate screw (Fig.17). Proceed with the assembly of all the intermediate balusters and close underneath
using the plastic caps. In order to provide the railing with greater rigidity, a further pawl, is applied to the last baluster, which should be fixed to
the slab (Fig.18 - B and 19). In the case of wooden floor / slab use only screws for wood, of the hanger bolt / leg bolt type, to replace those
provided. In case there is an external railing (optional accessory) for the landing, see the diagrams shown in (Fig.21). The internal baluster of
the landing should be joined with a further baluster previously cut to the right size (Fig.25 - F).
10) Assembly of the handrail
Assemble the handrails using the threaded rod and washer (Fig. 20 - A). Fix the balusters to the handrail by means of the appropriate
self-threading screws as shown in (Fig. 14). Apply the caps to the ends of the handrail (Fig. 22 - C). To connect the handrail of the first flight to
the handrail of the second flight, use the baluster ring and fix it with the appropriate connector and handrail cap (Fig. 23 - D). Where a landing
is present, the external railing (optional accessory) should be connected as shown in (Fig. 24 - E).
11) Balustrade (optional accessory)
The assembly diagrams shown on page 15 (optional accessory) show the most common types of assembly for any balusters present (Fig.26,
27, 28 - G, 30 - H). In order to give greater rigidity to the section of balustrade that are more than one metre long, use the "colonna stop"
(optional accessory) as indicated in (Fig.29). In the case of wooden floor/slab use only screws for wood, of the hanger bolt/leg bolt type, to
replace those provided.
12) Eventual absence of railing
The supports for the stiffening of the stair are composed by pieces of balusters of Y and W lenghts according to the calculated riser (Fig. YY)
and they have to be closed on the top and on the bottom with the proper plastic caps. The little supports are got cutting to measure the
balusters of the railing.
