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 proceeding with installation, carefully read the TAB. 2 (NUMBER OF PLASTIC SPACERS) in order to arrange the
rises so that the landing is 1 cm higher than the arrival floor (see Landing assembly).
Staircase assembly
1. Identify the point where to fasten the central column base (G03) taking into account that the landing (E03) must
rest on the arrival floor (minimum 2cm permitted).
2. Screw the bushing (B46) onto the base (G03) using the screw (B17) and mark the three points for the dowels
(B13) on the floor, then drill and fasten. Screw the central column (G02) onto the base.
3. Prepare all the base supports fitting the plastic spacers and end spacer (find the required number of spacers in
the table).
Fit the staircase components on the central column in the following order:
1 - 1st base support (D14) with the number of plastic spacers (D03) previously found in the table and the end
spacer (D02).
2 - Tread (L01).
3 - Base support (D04) with the number of plastic spacers (D03) previously found in the table and the end
spacer (D02).
4. Screw the threaded tie-rod (G01) onto the end of the central column (G02) bearing in mind that the end baluster
(C02) will be screwed onto its top end.
5. Continue fitting the components as above with the difference that the centring washers (D01) must also be fitted
immediately before and after each tread in correspondence to the threaded bar (G01).
6. After the landing (E03) fit the end washer (B05) and the Belleville washer (B04) and tighten with the nut (B03)
without overtightening.
7. Finally fasten the landing (see Landing assembly).
8. Position the treads angularly.
9. Finally tighten the nut (B03) with force.
Railing assembly
10. Heat the handrail to a temperature of approximately 75-80ºC so that it can easily be shaped by hand.
Then position it on the balusters (C01) previously fitted starting from the top.
Complete the operation before the handrail cools down too much.
11. Drill the holes in the handrail in correspondence to the existing holes in the balusters and secure it with the
relative screws (BF5 – B09 – B10).
The handrail can easily be heated as follows (fig. 2):
1. Place it on a flat surface (e.g. the crate cover).
2. For about 5 minutes sweep a flame over it with circular movements without staying in one spot.
3. Turn it over and repeat the operation.
Other methods can be used, for example, in hot climates it is sufficient to expose the handrail to the sun.
Landing assembly
12. Arrange the rises in such a way that the ends A and B of the landing graze the floor (FIG. 1).
13. Fit the threaded tie-rod (B74) with the screw (B73), the washers (B72) and the nut (B78) to the landing without
overtightening (fig. 3).
14. Fully screw down the nut (B71) on the tie-rod (B74).
Fit the bracket and then the nut (B71) screwing it on flush with the lower end of the tie-rod (B74).
15. Slide the bracket holding it resting on the nut (B71) up to the side of the floor.
Drill the hole (14 mm diameter, 120 mm deep) in correspondence to the cement curb using one of the two holes
in the bracket as reference.
Fit the expansion screw (B58) and finally lock the bracket on the floor.
16. Act on the lower nut (B71) until the points A-B-C (drawing 4) are in contact with the floor.
17. Lock the bracket on the tie-rod acting on the nut (B71) and tighten the screw (B73) with force.
