Trapezoidal sheet metal roofing
In the case of a trapezoidal sheet metal roof, the hydraulic connections can be positioned in a corrugation recess to
limit the height of the modules.
The flexible hoses can either run perpendicular to the corrugations if the installation system raises the modules higher
than the hose diameters, see Table 1, or run in the corrugation recess in the opposite case.
A detailed layout plan is then mandatory to ensure that the hydraulic connections do not interfere with the roof
covering.

DN15 fitting
See the characteristics of the DN15 hydraulic hose in table 1.
The minimum elevation of the module with regard to the corrugation crest is 22 mm.
In this case, the edge of the hydraulic fitting can be placed 34 mm to the edge of the corrugation crest.

DN26 fitting
See the characteristics of the DN26 hydraulic hose in table 1.
The minimum elevation of the module with regard to the corrugation crest is 36 mm.
In this case, the edge of the hydraulic fitting can be placed 60 mm to the edge of the corrugation crest.
