INSTALLATION INSTRUCTIONS Load classes to EN 1433 Typ I / Typ M nach EN 1433 Fitting direction Options for underground pipe connections Class A 15 Traffic areas which can be used only by pedestrians and cyclists. Class B 125 Footpaths, pedestrian precincts and similar areas, car park areas, multistory parking. Class C 250 Kerb areas, road shoulders without vehicle traffic and similar. Class D 400 Road surfaces (also pedestrian streets), road shoulders and parking space for all kinds of road-going vehicles. Class E 600 Surfaces required to bear heavy wheel loads, e.g. harbors and dock facilities. Class F 900 Surfaces subjected to extremely high wheel loads, e.g. airport operation areas. Typ I A drainage channel type I does not require a concrete encase- ment for bearing the loads. Foundations are only required to discharge the exerted vertical and horizontal forces. The laying direction of the channel is always opposite to the direction of flow (green arrows!) and starts at the ground pipe joint. If elements are laid in two directions it is necessary to join Element with vertical outlet Feed box incl. Dirt catcher Typ M A drainage channel type M requires a foundation and encasement of concrete that can discharge occurring vertical and horizontal loads into the foundation after installation.

INSTALLATION INSTRUCTIONS Note the following basic principles when laying drainage channels • The type of drainage channel to be laid depends on the installation location, corresponding traffic loads, and the planned top course. Installation locations are organized in classes A 15 to F900 by EN 1433. From class C 250 onwards all gratings must be anchored to ensure traffic safety. The foundation of the drainage channel must be suitable to bear the traffic load. • Horizontal loads arising from traffic or thermal behavior of the surface layer must be transferred by means of sufficiently dimensioned concrete encasement of the channel sections and by expansion joints running longitudinally to the channel, especially in the case of adjoining concrete surfaces. The laying direction of the channel is always opposite to the direction of flow and starts at the ground pipe joint. • Subsequent surfaces must be executed to be approx. 3 to 5 mm higher than the top edge of the grating or edge protection taking setting and compression into account. Undermining and washing out of decking and channels must be prevented by suitable measures. • Where extreme horizontal forces are expected at right angles to the channel, e.g. on railway crossings, ramps or highways, the drainage channels should be secured laterally with reinforced decking concrete.
