General instructins When installing flat rf drainage elements, the fllwing regulatins, amngst thers, must be bserved: DIN EN 12056-3, DIN 1986-100, DIN 1986-3, DIN 18531, DIN 18195, DIN 18234, flat rf guidelines Sme imprtant pints f these systems f rules are listed belw: Rf utlets are t be fitted at the lwest pint f a rf. In the case f steel trapeze prfile substructures, penetratins are t be reinfrced by a strengthening sheet. The basic bdy is t be jined with the substructure. A skewing f the extensin unit thrugh relative mvements f the rf cnstructin must be prevented (e.g. thrugh mechanical fixing f the unit). The flanges f the rf utlets and extensin units are t be installed Rf utlets must be freely accessible fr maintenance purpses. Rf utlets and the cnnected pipelines have t be prtected against "sweating", where apprpriate, with e.g. aluminium-cated rck wl. In the case f waterprfing seals f nly ne layer and/r lsely laid, then screw-n flange jints must be installed with permanently cmpatible material f the same type as the waterprfing (r a suitable elastmer) fitted n bth sides. The blts f screwed-n-flange jints must be checked and tightened at least three times during the curse f the fitting wrk, using a trque wrench. Rf utlets have t be serviced at least twice per year. 3
Especially with screw-n-flange utlets in general, the fllwing pints shuld be bserved and adhered: In case f a bituminus seal, the sealing sleeves are nt t be used. The fixed flange f the utlet bdy is t be pretreated with bitumen primer. The bitumen pave-track r tracks have t be welded directly n the fixed flange f the utlet bdy. Seam verlap in the flange area is nt allwed. Fleece-clad rf sheets shuld nt be cnnected by a flange (capillary effect). Befre sealing the flange the sealing tracks have t be preheated. Lse-laid waterprfing layers and screw-n-flange cnnectins must be prtected n bth sides with tlerable supplements r with material cmpatible elastmers The cmpatibility f the delivery f rf utlets r extensin units with their belnging sealing sleeves t the rfing material shuld be examined independently. If necessary the sealing sleeves have t be replaced by the rfing material. Screw-n-flange cnnectins must be attract with a trque wrench during the assembly time at least three times, timing > 24 hurs. 4
1.. SitaStandard SitaTrendy - SitaDSS Prfi rf utlet with extensin element 1.1 Lcate the psitin fr the rf utlet hle (ø 250 mm) at the lwest pint f the rf cnstructin. In the case f steel trapeze prfiles, care must be taken that wrked area des nt later suffer frm crrsin. 1.2 In the case f steel trapeze prfiles, care must be taken that wrked area des nt later suffer frm crrsin. 1.3 The rf utlet is t be put int the hle in the rf and mechanically fixed. 1.4 The vapur barrier is t be fitted t the flange r cnnecting sleeve, by means f adhesive r welding. 1.5 The angled sealing ring fr stemmed water safety is t be placed int the utlet s that the upper lip flatly verlaps the cllar edge. 1.6 Fit the thermal insulatin and cut ut the utline f the extensin unit. 5
1.7 Shrten the extensin element where apprpriate in such a way that the utlet crsssectin in the case f angled rf utlets is preserved. Apply attached lubricant medium t the lwer parts f the angled sealing ring and the extensin unit. 1.8 Push the extensin element thrugh the angled sealing ring in the rf utlet. The extensin element must at least be flush with the lwer edge f the angled sealing ring. Fix the extensin element mechanically in the substructure. 1.9 The rf waterprfing is t be fitted t the flange r cnnecting sleeve, by means f adhesive r welding. Attentin: The fllwing pint 1.10 is valid fr the series SitaStandard and SitaTrendy.

2. SitaTrendy screw-n n-flange - SitaDSS Prfi screw-n n-flange 2.1 Place the screw-n-flange rf utlet r the extensin unit in the existing rf cnstructin, and screw it tgether with surface in the prepared vertical hle. Attentin: The cmpatibility f the rfing material with the rf utlet s and/r extensin unit s sealing sleeve which may have been delivered with the prduct, must be checked and if necessary crrected. 2.2 Lay the large sealing sleeve centrally n the rf utlet bdy. In the case f a bituminus waterprfing layer, this is t be welded directly t the utlet bdy. 2.3 Rll ut the waterprfing curse ver the rf utlet, and cut ut the middle f this (ø apprx. 150 mm). If a number f curses have t be flanged in, then these are always t be led up t the drain entrance. A cvering ver f the waterprfing curses in the area f the flange is nt allwed. 2.4 Lay the small sealing sleeve centrally n the rf utlet bdy. 7
The sealing sleeve and the rf waterprfing curses are t be warmed befre the flanging in. Place the aluminium lse flange in its preferred psitin. The hles in the drain bdy are necessary fr prductin purpses. One in the insertin ring which is built int the drain bdy achieves the impermeability in every psitin f the lse flange. 2.5 Tighten the cuntersunk head screws which were cntained in the set with a pwer screwdriver in a unifrm ppsing pattern with a maximum trque f 9 Nm. Accrding t the German standard DIN 18195, the screws f a lse/fixed flange are t be checked and tightened at least three times, after perids f mre than 24 hurs each. Allw the dme grate t engage frm abve in the screw flange. Attentin: The assembly f the dme grate is valid fr the series SitaTrendy screw-n-flange.
