OPW Installation, Operation, and Maintenance Manual, Page 77 PORTANT: Before installing the valve, allow seal- nt to cure for 24 hours. STEP 13: REMOVE ELASTIC BAND Remove the elastic band securing the float to the valve body. The float will move into an outward position. STEP 14: INSERT DROP TUBE Make sure the 0 Ring gasket is under the flange of the inlet tube. Hold the float down against the valve body and slowly insert the drop tube overfill valve into the riser pipe. Do not force valve into the riser pipe. If any obstruction or foreign matter interfereswith smooth insertion of the valve, the riser pipe must becleared. WARNING Failure to follow the assem" bly and installation instructions or use of excessive force to insert the OPW 61 SO will VOID THE WARRANTYI Diff iculty in removing the existing fill tube (if there is one) means there may be an obstruction in the riser pipe. Look for burrs, deformations, excess tank lin- ing material or other projections that may interfere with easy insertion of the OPW 61 SO. The 61 SO is designed for insertion into schedule 40 pipe, If schedule SO pipe has been used for the riser, the 61 SO cannot be in- stalled. If seamed pipe has been used, the internal weld bead may interfere with the OPW 6130 and prevent installation. If the OPW 61 SO won't slip in easily DON'T FORCE ITI Damage to the valve may result if excess force is used. Examine the riser pipe carefully; deter- mine the nature of the obstruction; take appropriate steps to remove it. STEP 15: 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 position as it passes into the tank. Make sure that the float is aligned along the length of the tank. The length of the tank can easily be determined by locating other manholes or pump boxes that are installed around other tank fittings. Look into the drop tube and align the deflector with the length of the tank. Executive Order VR- 102-Q CAUTION: No obstruction in the tank can be within 13" from the center of the riser pipe or the valve may not operate properly. STEP 16: ALIGN VALVE Install the OPW Jack Screw Kit and a 4" nipple to lock the valve in place. Refer to the Installation Instructions supplied with the Jack Screw Kit. Install the Rotatable Product Adaptor (Refer to Installation Instructions sup- plied with the Rotatable Product Adaptor.) Make sure that the valve does not rotate while tightening the adaptor by observing the position of the deflector. The valve must remain aligned along the length of the tank as in Step 15. Repeat this step as necessary to assure proper valve alignment. Val* Retr0'.ery I �T Max 6a F. it I TI.Oe Cvt . �. rE3Fm'7tE � l ar r'oat A,:�� l.4ndt` o' Tar.: Figure 16 —+r Figure 96A
