30 Assemy informtion FOR DUCTING REQUIRING TIGHTNESS CLASS C ACCORDING TO DIN EN 1507 Sever fctors determine whether the tightness css cn e ensured. The fundment requirement is tht the components re crefuy mnufctured. The order must stte which tightness css is needed. Assemy on site is equy importnt in this respect. As the mnufcturer, we woud ike to provide you with the necessry informtion. Unoding nd trnsporting components Visuy check components for extern dmge. Check tht tightness css C is correcty shown on the es. Unod the components with cre to void ny dmge. Use suite equipment to trnsport the components (do not pu on the frme joint). Store them in proper mnner on the site. Assemy Visuy check the components gin for extern dmge. Mke sure tht the frme joint is cen. Attch the duct tpe fush with the inside edge of the duct profie. Aout 2 dys ter, check tht the ot connections on the frme re tight (duct tpe hs setted). Ony use mting prts with the speciy suppied frmes (with intern sent). Fsten the frme using tighty cosing ind rivets, so tht it is positivey seted on the component (do not use sef-tpping screws). Afterwrds, se the corner re of the profie frme on the inside. Do not fsten ny ddition ttchments with sef-tpping screws (ony ind rivets). Se ttchments fterwrds using suite sent (compint with VDI 6022). Fexie connectors, ouvres, siencers etc. must e shown to meet the requirements of tightness css C. Lekge tests On-site ekge tests in ccordnce with DIN EN re offered y extern, independent contrctors. The tests shoud redy e defined t the pnning stge nd crried out during the ssemy stge. See the informtion sheet Mesuring ektightness on ducting systems ( Attch the duct tpe crosswise in the corner re of the profie. Mke sure the ot connections on the corners re tight. Use duct rckets for edge engths ove 400 mm, with mximum spcing of 200 mm. Ducting 35
