STEP 20: PREPARE FILL AKER FOR VALVE INSERTION IMPORTANT: inspect The riser pipe for any foreign material, Over sprayfrern tank relining or Jew internal burrs inside of pipe must be removed prior to Installa- tion. Failure to have an unobstructed riser pipe may prevent proper installation or operation of the valve_ Thoroughly dean top of riser pipe. STEP 21: REMOVE ELASTIC RAND Remove the elastic band securing the float to the valve body. The float wilt move Into) an outward position. STEP 22: INSERT DROP TUBE Make sure the upper 04ing gasket is under the flange of the inlet tube. Hold the float down against the valve body and slowy Insert the drop lube overAil varve into the riser pipe. Do not force valve Into the riser pipe. If any obstruction or foreign matter interferes with smooth Iiisertion of the valve, the Ilse( pipe must be cleared.

DAtulty pri rertiov6ny the existing fill tube (if them Is one) means there may be an obstruction in the riser pipe. Look for burrs, defor- mations, excess tank lining mated- di Or Other Waled-fans that may interfere v4th easy insertion of the / OPW 7150. The 715015 deugned for insertion into schedule 40 pipe. If figure 22 schedule 130 pipe has been used for the riser, the 71S0 Cannot be Installed. if warned pipe ha's been Used, the internal wetd bead may interfere with the OPW71.Oafl1 prevent installation. If The ciPw 7150 won't sHp in easily DONT FORCE FT! Damage to the valve may result if excecc force is used. Examine the riser pipe carefully, determine the nature of the obstnic- lion; take appropriate steps to remove IL STEP 23: CHECK INSTALLATION Insert the drop tube all the way Into the tank until the flange and gasket seat onto the top of the Face Seal Adaptor. The float will swing out into the operating pas:FL-ion as 't1 panes into the Figure 23 Make sure that the float is aligned along the length ef the tank. The length of the tank can easily be deter- mined by locating other manholes or pomp boxes that are installed around other tank fittings, Look Into the drop tube and align the deflector with the length of the Ilk- For testab e_madets only Unthread the socket adap- tor assembly from the inlet tube (a 3(r square dr ive ectemion will attach to the socket adaptor, secure al/ tools to ensure they don't fall into the tank er valve) and ensure noel and poppet move 1 reely when socket &tip tor assernla.ly IS pulled on. When looking down into the Upper tube ensure poppet is visible when socket adap- tor is pulled and resets properly when socket adaptor is released, See paqc 17 for full testing details_ if poppet does oot actuate freer take appropriate steps to C01712t1 before proceeding. CAUTION: No obstruction in the tank can ha within 14" from the center of the riser pipe or the valve may not operate property (See Flours 241. STEP 244 ALIGN VALVE Install the OPW JackScrew IQ and a 4 NPT nipple to lock the valve in place. Refer to the Installation Instruc- tions supplied wfth the Jack Strew Kit. For testable models tniSUre that the socket adaptor Is abetted so it does not interfere with the Jack screw kit. (see Fig ure 24A). Install the Rotatable Product Adaptor (Refer to Installation Instructions supplied with the Product Adaptor.) Make sure that the valve does not rotate while tightening the adaptor by observing the position of the deflector.
