Art. 45.1 IN P.V.C. - 45.10 IN P.P. POLYOLEFIN
1 - Spreading of the P.V.C. membrane; cut the membrane by the hole.
2 - Try the drain in the hole and, at the same time, mark the point to cut in relation to the thickness of the wall. The cutting of the pipe shall be made in such a way that the lower part is 5 mm. longer than the higher one, in case this is used with curves art. 46 and 47. But if the drain is placed in the box art. 118, it shall be cut at 45° (see drawing A) and laid with a grade of 3°.
3 - Weld the drain flange on the membrane (see drawing B), with hot air or with adhesives suitable for plasticized P.V.C.
4 - Before inserting the curve, pass an adhesive cord suitable for plasticized P.V.C.After having inserted the curves, make sure that the drain pipe is inserted in the four tangs that are inside the curves.
5 - Insert the Leafgrate/Gravelgrate - art. 44.1.
