2. Tank Offloading, Installation and Maintenance Tank Offloading, Installation and Maintenance This information applies to all clean water GRP tanks, ElevaTANK and QuadraTANK units. Specification GRP tank products are manufactured from non-corrosive materials to the requirements of EN 13280:2001 (formerly BS7491 Part 1 and 2) and incorporating the quality control requirements of BS EN ISO 9002:2000. Internal surfaces in contact with the fluid are smooth isophthalic gel-coated with a high gloss finish to improve resistance to bacteriological growth. - Page 10 2. Tank Offloading, Installation and Maintenance All tanks and tank systems are factory water tested at manufacture stage. However, connections may be disturbed during transportation and should be checked for tightness before the tank is filled with water and carefully monitored once filled to ensure there is no leakage. It is recommended that tanks should be sterilised before putting into use.
