The fundment requirement is tht the components re crefuy mnufctured. The order must stte which irtightness css is needed. Assemy on site is equy importnt s regrds irtightness. 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 irtightness 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 site. Assemy Visuy check the components gin for extern dmge. Mke sure the frme joint is cen. Attch the duct tpe fush with the inside edge of the duct section. Attch the duct tpe crosswise in the corner re of the section. 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. The oose frme is temporriy fixed on the side tht is to e shortened in order to stiise the component nd reduce the risk of injury. Detch the oose frme from the provision fstening of the component, shorten the component s is required or necessry, push the oose frme s fr s it wi go, mking sure it is fush with the component. Fsten the oose frme y mens of seed ind rivets (mximum 150 mm distnce etween them) (Attention, do not use sef-tpping screws!) Susequent, on-site seing ong the section frme, on the entire interior of the frme nd inside the corners (use ony sents suite for ter use tht is, for exmpe, compint with VDI 6022, sovent-free, etc.) Do not fsten ny ddition ttchments with sef-tpping screws (ony with seed ind rivets).
