INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS WSG GRILAIR WEATHER-PROOF LOUVRES PRODUCT DESIGNATION WSG-50…, WSG-75…, WSG-h…, WSG-SDf…, WSG-SDs… TECHNICAL SPECIFICATIONS Max. size W x H: 1-part max. 4000 x 8000 mm (subject to shipping) ATEX WSG dampers are only approved in specific designs and with appropriate identification for Zones 1, 21 21 and 22 according 2, or 2, 22 according to to ATEX Directive 94/9/EC. ATEX Directive 2014/34/EU. If the fitter or operator changes the louvres in any way, the ATEX approval becomes null and void. It is important to ensure that the louvres and additional equipment are installed in compliance with zoning requirements. In principle, avoid all damage caused by external influences. Do not lift the louvres by the slats. Louvres with a maximum weight of 50 kg can be lifted by the C-profile frame. With heavy louvres use the ring bolt suspensions provided. Do not use individual slats under any circumstances as footholds during installation. Any damage, e.g. deformation of the slats, dents, impacts, frame warpage etc. can lead to insufficient water drainage and undesired flow generated noise. Report all damage immediately to the supplier or manufacturer. Damage may impair the proper functioning of the louvre and at best cause dangerous circumstances to occur. WSG-50 & WSG-75: These louvres are only suitable for vertical applications. The louvres must be adequately sealed to fixtures and in the area of flanges. This is the responsibility of the planning engineer or fitter. The louvre is then ready to operate after an air duct and water drains are connected without warpage. WSG-h & WSG-SDf & WSG-SDs: These WSG models require a base frame construction which must be produced by the customer. With louvres which are larger than 4 m² or with multipart louvres, the customer must produce additional support structures in the area of the surrounding water duct. The planning engineer or fitter is responsible for sufficient support. The louvre is placed and fixed to the structure mentioned above. Make absolutely sure that all the surrounding flanges are seated properly after the louvre is positioned. To ensure drainage of water from the lower slats, the louvre must be installed with a slight inclination in the direction of the slats. ATEX: Under no circumstances may ATEX louvres be fitted after a fall or impact with visible or concealed damage. ATEX: All relevant national and international standards and regulations for Ex zones must be observed. On louvres with ATEX functionality in particular, the louvre housing must be earthed using the earthing braids attached by the manufacturer. No mechanical changes may be made to the product. In addition do not attach any components (frost monitors, temperature sensors, etc.) to the louvres if they have not been analyzed for ignition risk by the appropriate manufacturers or approved for ATEX zones.

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS WSG GRILAIR WEATHER-PROOF LOUVRES Depending on the degree of soiling, clean the louvre at regular intervals to remove leaves and other residue. Leaves can be removed from WSG models using compressed air, leaf blowers or brushes. Make sure that as few foreign bodies as possible (leaves, sticks etc.) enter the louvre through the top wire mesh. Never step on the slats during cleaning work. With very large and poorly accessible WSG-h devices, we advise you to place a wooden board or similar over the louvre. Make sure that the wooden board is of...
