tYtE W P1P� 12. Fill manhole with clean water to outlet invert.The 3/8" (9,5 <br /> mm)guide rod should be approximately 8" (200 mm)above <br /> the cage top plate. <br /> go 13. Push down gently on guide rod, release pressure from <br /> = rod and allow float to rise. Upon rising, unit is ready for <br /> 1* operation. <br /> A 14. Step#12 is used periodically to insure float operation. If <br /> float remains closed,gently pull on lift cable to break seat <br /> suction. <br /> ® NOTE; DO NOT ATTEMPT TO OPEN VALVE WHEN SUMP IS <br /> EMPTY OF WATER. WATER LEVEL MUST BE AT INVERT OF <br /> OUTLET TO LIFT. <br /> NOTE: IF FLOAT DID NOT OPEN, FILL VENT PIPE WITH WATER <br /> TO EQUALIZE PRESSURE ON THE VALVE FLOAT. <br /> AN spa an 60 am sm <br /> FLOW RATE 19M <br /> Figure 2.OSV-6 and OSV-8 inch <br /> `.-✓ F07 <br /> `'I 3 J✓'PLOAT tw <br /> t163f t�8E I V 42-17ya pipe <br /> 7 [ �)fIEYIfl131iq R66$ <br /> noAr solar: <br /> 0 0 ekwr g w$IIaE <br /> tfo`a MYNVN qLI .GgIC <br /> y W - a47 IN`ArPoM Nam IRM - <br /> Yi ,r^� c SU40 ormw PM Iwr BY&L MP tKILE <br /> Lq 6LWAM fiNM <br /> 11 IIQ11>711151'H yIIIRR <br /> FLOW pip, (O " OSV discharge pipe(not shown here and plain end connections) <br /> to be supplied by Others.The contractor,at his discretion, may <br /> Figure 3.05V-10 and 05V-12 inch solvent glue to the valve discharge elbow,or select other suitable <br /> means for connecting OSV discharge elbow to outlet pipe. <br /> A. Plain End Connections <br /> Installation Valves with plain end connections can be connected with PVC <br /> 1. Unit must be installed utilizing a crane, backhoe,fork coupling and two stainless steel worm drive hose clamps.Slide <br /> truck,or similar equipment due to the size and weight the coupling on valve discharge elbow and install the clamps by <br /> (approximately 300-425 pounds[136-193 Kg,[), sliding them on the coupling. Line up the valve discharge elbow <br /> with outlet pipe, leave 1/4"gap(6 mm)between pipe ends,and <br /> 2. Pick up unit slowly using the supplied lifting cable harness, slide this coupling and clamp on the outlet pipe. Do not tighten <br /> 3. Unit will tip to the outlet pipe side.This is the desired angle the hose clamps at this time. <br /> to prevent excess pressure on the float cage. <br /> 4. Lower unit into manhole. B. Flanged End Connections <br /> 5. Remove lifting harness for use on next valve. Line up the flange bolt holes, insert a gasket and bolt flanges. Do <br /> 6. Remove rubber boot. (To be installed outside of sump) <br /> not tighten bolts at this time. <br /> 7. Reposition valve to allow outlet pipe of valve to extend ATTENTION: FLANGES SUPPLIED WITH THE VALVES ARE FLAT <br /> through manhole plus 4"(101 mm). Make sure valve top FACE; MAKE SURE THE MATING FLANGE IS OF THE SAME <br /> plate is level in both directions. DESIGN. USE OF RAISED FLANGES WILL BREAK THE PVC <br /> FLANGES. <br /> 8.
