OPW Installation, Operation, and Maintenance Manual, Page 74 Executive Order VR -102-Q ®Registered T.M. Owens Corning Fiberglass Corporation ASSEMBLY INSTRUCTIONS Tape measure s: Riser Pipe ( ) with To Tank ( ) Face Top To peal Adaptor Tank Bot om EXAMPLE 1) For an Owens-Corning Madel G-3 FiberglassCR7 Tank Calibration Chart: Tank Capacity - 10,000 gal., nominal 9,403 gal. NOTE: Use actual capacity only 21 95% of actual tank capacity = 0.95 x 9403 gal. _ 8933 gal. 3) The closest numberwhich is less than 8933 gal. Is 8910 gal. Choosing the closest number less than 95% of actual capacity ensures that the initial shutoff will occur when the tank is no more than 95% full. 4) The calibration chart reading of 8910 galcorre- sponds to a dipstick measurement of 82". 5) Dipstick number (X) = 82" Tank diameter (Y) = 92" (Y) - (X) _ (Z) (92" 2" =10") (Z) = 10" 6) (Z)-2 =C (10" - 2" = 8") C=8" 7) Is 8" less than 6-11211? NO Measure the distance from the top of the FSA- 400Face Seal Adaptor installed on the riser pipe to the inside, top lip of the storage tank and obtain measurement (A). Upper tube length = C + (A) IMPORTANT: Each of the numbered steps in the instal- lation instructions are designed as a CHECK LIST to en- sure proper installation and trouble free operation of the W61 SO Overfill Prevention Valve. Road and follow these steps carefully, checking them off as you proceed. Figure numbers correspond to step numbers for easy reference. STEP 1: MEASURE Install the OPW Face Seal Adaptorandthe OPWThread- on Spill Container on the Fill Riser (Refer to the Installa- tion Instructions Supplied with the Spill Container). In- sert a tape measure through the riser pipe and hook it under the inside of the tank in the lengthwise direction. Measure the distance from the top of the Face Seal Adaptor threads inside the base of the spill container bucket just below the drain valve outlet window to the inside, top lip of the storage tank (Dim. "A") (See Figure 1 &1A). The top flange on the 61 SO will rest on the Face Seal Adaptor just below the drain valve outlet, and be locked in place between the Face Seal Adaptor and the 4" nipple that is installed in the spill container with the Jack Screw Kit (See Figure 1 A). (For riser pipe configu- rations other than that shown, consult installation drawings or use other necessary means to measure Di- mension "A"). Using a tape measure, measure the distance from the top of the Face Seal Adaptor in the spill container to the bottom of the tank (Dim. "B"). IMPORTANT: Inspect the riser pipe for any foreign ma- terial. Over spray from tank relining or any internal burrs inside of pipe must be removed prior to installation. Failure to have an unobstructed riser pipe may prevent proper installation and operation of the valve. The 61 SO is designed for installation into schedule 40 riser pipes. The 61 SO cannot be installed into schedule 80 riser pipes, STEP 2: MARKTHETUBE Use the result from Step 1 and HOW TO LOCA TE THE POSITION OF THE 61 SO AT 95 % TANK CAPACITYto mark the upper tube. Measure the distance from the point where the upper tube and valve body meet. For "Cmeasurements greater than 6- 1/2" " use tape measure to mark the calculated upper tube length onto the upper tube.
