OPW Installation, Operation, and Maintenance Manual, Page 78 Executive Order VR -102-Q <br />STEP 17: INSTALL WARNING PLATE <br />Slide the tie wrap over the warning <br />plate ears and position warning <br />plate against riser pipe approxk <br />mately 1" below the adaptor, <br />Tighten the tie wrap securely. The <br />valve is now fully installed and in <br />operating position. <br />STEP 18: VALVE REMOVAL <br />The valve can be removed for tank -'``�` <br />leak testing, inspection, etc., by <br />removing the Rotatable Product <br />Adaptor, the 4" nipple, and the Jack Screw Kit, Figure 17 <br />Reinstall per the above instructions. <br />STEP 19: ELECTRONIC LIQUID LEVEL MONITORING <br />If an electronic level monitor is installed, it must be cali- <br />brated to match the top of the 61 SO valve body, which <br />must correlate with 95% of the actual tank capacity. <br />PREVENTATIVE MAINTENANCE <br />Annually, inspect the flapper in the 61 SO to see that it is <br />open by looking down the drop tube opening. Test the <br />61 SO droptubeseals with CARB procedure TP -201.1 D. <br />If the drop tube seal passes testing, no further mainte- <br />nance is required. If the drop tube fails testing, replace <br />the drop tube seal with OPW P/N: H 11931 M for 4" <br />Tubes. Re -test the 61 SO drop tube with CARB proce- <br />dure TP -201.1 D. If this does not correct the leak the <br />61 SO needs to be replaced. <br />CAUTION: Do not insert any foreign object into drop <br />tube if flapper is in the closed position. For example <br />a tank level measuring stick. This will damage the <br />valve and void the Warranty. ALWAYS check flapper <br />location before "sticking" the tank. If flapper is in <br />the closed position the tank is either over filled and <br />you need to wait until the liquid level goes down or <br />the 61 SO is damaged and needs to be replaced. <br />61S0 Performance <br />Specifications: <br />This Overfill Prevention Valve has been manufactured <br />and tested td oanmetthe foll <br />, ,owing California specifi- <br />cations.
