It is important to ensure that the damper and addition-al equipment are installed in compliance with zoning requirements.ShipmentIn principle, avoid all damage caused by external influ-ences. Never lift dampers by the slats or the outer linkages.Dampers with a maximum weight of 50 kg can be liftedby the C-profile frame. With heavier dampers, use at leastfour points at the corner angles as suspension points. Donot use individual slats under any circumstances as foot-holds during installation. Report any damage, e.g. defor-mation of slats, dents, impacts or warping of the C-profileframe etc. immediately to the supplier or manufacturer.This may impair the proper functioning of the damper andat best cause dangerous circumstances to occur.ATEX: Under no circumstances may ATEX dampers be fittedafter a fall or impact with visible or concealed damage.InstallationMount the dampers warp-free, tension-free, on a flat sur-face and without any angular errors in the damper frame.When mounting, use the 4 corner holes provided as stand-ard. With larger dampers, fit additional flange couplingsat spacings of 200–500 mm. This is the responsibility ofthe planning engineer or fitter. When installation is com-plete, check the angle of the damper frame. It must beexactly 90°. Correct any deviations immediately. In addi-tion check the free movement of the slats, linkage andgear wheels. Avoid as far as possible any reduction in free-dom of movement on customer premises when installinginsulation materials, installation ducts, auxiliary structuresetc. If this is not observed, it can lead to considerable dis-ruptions in operation, e.g. slats rub against the damperframe, increased damper torque, damper fails to open orclose, reduced leak tightness, fatigue fractures on theaxles etc.Only dampers which are equipped with collar bushingscan be fitted with vertical slats (also called standing slats).In addition, make sure with this damper application thatadditional bolts or reinforcements are affixed with damp-ers larger than 1000×1000mm. The lower frame profileon which the entire slat weight rests must also be supportedby the customer. Sagging can lead to damper damageand plant outages.On models with side seals (Di, DIN, CEN, S etc.) protect theunits from impurities of all kinds during the installationphase. Drilling swarf and concrete chips can damage theside seals. Before starting up the dampers, wipe the sideseals thoroughly until they are dry.ATEX: All relevant national and international standardsand regulations for Ex zones must be observed. On damp-ers with ATEX functionality in particular, the damper hous-ing must be earthed using the earthing braids attachedby the manufacturer. No mechanical changes may bemade to the product. In addition do not attach any com-ponents (motors, limit switches, etc.) to the damper if theyhave not been analyzed for ignition risk by the appropriatemanufacturers or approved for ATEX zones.It is prohibited to drill holes or fit bolts or screws in the in-terior of the dampers. This could lead to damage or dis-turb damper operation.
