Y <br /> B. SUMP REDUCERS <br /> To prevent leakage and to <br /> Insure unit integrity, all FRP <br /> sump reducers must be slip <br /> fitted over the sump body or <br /> tube,bonded and sealed. See <br /> Bonding Instructions. T.C. oruLrrx <br /> friction lids simply slip over ..T <br /> reducer top. "B"type,water <br /> resistant,lid systems utilize pull <br /> down"dog„ or tie downs to TYPE Wf <br /> hold the lid securely against the <br /> sealing gasket on the reducer <br /> rim. "A"type lid systems are MTE's" <br /> gasketed and bolted watertight <br /> with wing nuts, lock and flat <br /> washers. <br /> C. SUMP PENETRATIONS <br /> Piping and electrical conduit penetrations are made using only a Listed/Approved penetration, <br /> sealing device. Use care when drilling through filament wound sump riser tubes. Do not force hole <br /> saw,for FRP sumps, cut hole slowly, half way through from both sides(inside and out)to prevent <br /> fraying of filament strands. Always use correct size hole saw or drill. Do not fiberglass bond piping <br /> or conduit directly to FRP sumps as this will not allow any movement, due to ground settling,back- <br /> fill, etc. <br /> INSTALLATION PRODCEDCI'RE <br /> D. PRE-BONDING SURFACE PREPARATION <br /> 1. After positioning sumps onto tank collar or after placing reducer on sump riser tube,use disc <br /> sander,with medium to heavy grit sand paper,to scuff up all seam areas a minimum of 4" each <br /> side of the point where the components join. It is very important that this be done fully, as the <br /> bonding materials will not adhere to any surface which has not been sanded. <br /> BE SURE TO WEAR A <br /> DUST MASK Brush <br /> sanding dust from <br /> seam areas. <br /> "TC'LIO <br /> E.
