Use set —1 to secure tool to upper tube 71SO-TOOLC Modifications for Tastable Inlet STEP 98: INSERT 71 SO-TOOLC OVER INLET TUBE To Install the 71 SO-TOOLC (sold separately) over the Inlet tube, first loosen the thumb screw, so the tool can pass freely over the Inlet tube flange. Align the slot on the tool with the key on the Inlet tube and Insert the tool down. See Figure 98.

The stop is factory installed at a distance be- tween 1-3/16N to 1-1/4' from the tip with the 71 So- TOOLC. If the stop Is not at the corma position it must be fixed before drilling. CAUTION: If the drill stop is not in the proper los a - tion failure of a pressure decay leak test may result. 71 S0-T00LC 0 Tip to stop dimension must bel-3/16'to 1-1/4' Figure 11 B STEP 128: DRILLHOLES With the Inlet tube and 7150-TOOLC In place, carefully drill a 3/16" diameter hole In the upper tube using the hole In the 71 SO-TOOLC as guide. The drill stop is po- sitioned so It will bottom out against the tool after the bit has drilled through the upper drop tube. If the stop Is positioned wrong either no hole will be drilled, or a through hole could potentially be drilled through the Inlet tube. If no hole Is drilled return to step 118 and check the stop dimension. If a hole Is drilled through the inlet tube or Into the screw hole the assembly Is not salvageable. Drill (2) more holes In the two remaining guide holes. r_j STEP IOB: TIGHTEN THE 7150-TOOLC Ensure that the tool seats flat against the top of the inlet tube. To prevent vertical movement of the tool during drilling, hand tighten the thumb screw against the up- per drop tube. See Figure 106. STEP 13: DIMPLE FIRST HOLE Remove tool. Remove any chips or burrs from the drill - Ing operation. Place the assembly on a solid surface. Using the punch supplied with the 7150 -TOOL, 71 SO- TOOLC, and 71 SO-TOOLCT, align the tip of the punch with the drilled hole and dimple the upper drop tube by striking the punch with a hammer until the drop tube Is formed Into countersunk hole In the inlet tube. After punching, remove any chips that may have fallen Into the Inlet tube screw hole. Figure 13 STEP 14: ASSEMBLE FIRST SCREW Ensure that the drop tube was formed Into the counter- sunk screw hole as shown In Figure 141f not return to Step 13. Apply black moly grease to screw and tighten first screw Into inlet tube with a screwdriver. Use only the taptlte screws that are supplied with the unit Smv Ing torque Is 20 in -lbs min. to 35 in -lbs max. Sam head should be flush with the drop tube. Do not over tight - Figure 14 Figure 128 STEP 15: DIMPLE REMAINING HOLES Remove any chips or burrs from the drilling operation. Dimple the next (2) holes as done In Step 13. Make sure the assembly is on a solid surface when punching. After punching, remove any chips that may have fallen Into the Inlet tube screw hole.

To prevent vertical movement of the tool during drilling, hand tighten the thumb screws against the up. per drop tube. See Figure 1 OC. STEP 11C PREPARE DRILL AND BIT Confirm that the stop on the 3/16' drill bit supplied with the 7150-TOOLCT is in the correct position before drilling. The stop is factory Installed at a distance be- tween 1-3/16'to 1-1/4' from the tip with the 71 SO- TOOLCf. If the stop is not at the correct position it must be fixed before drilling. CAUTION: If the drill stop is not in the proper loca- don failure of a pressure decay leak test may result STEP 18: LOWER TUBE ASSEMBLY If a vise Is used, clamp on the valve body casting only to avoid damage to the float and tubes. Thread the lower tube onto the valve body until the lower tube bottoms out on valve body. Tube can be tightened by hand or with a strap wrench. If a strap wrench Is used try ro po- sitlon It on the threaded Insert portion of the lower tube to prevent damaging the tube. Threaded Insert Figure 18 NOTE: Before installing the valve in the tank a pres- sure can be performed on the valve to check for vapor tightness. Seal off both ends of the tube with inflatable plumber's plugs. Apply a maximu m 10" W.C. (1 /3 PSI) air pressure. If pressure does not hold and a leak can be located with soap solution, do not install the valve. Send the valve back to OPW for warranty evaluation. CAUTION: Do not over -pressurize. Excess pressure can damage the valve. STEP 19: CUT LOWER TUBE Measuring from the underside of the inlet tube flange, mark the overall length of the drop tube a distance of (B) minus 6". Determine dimension (B) from the meas- urements taken in Step 1, Figure 1 (Top of the Face Seal Adapter below the drain valve outlet in the spill con- talnertothe bottom of'he tari Saw off the excess tube ata 45 -degree angle or per local codes or requlre- menu and file off any sharp burrs (Refer to Figure 24). Optional: Install the OPW Tank Bottom Protector on the lower tube (Refer to Installation Instructions sup- plied with the Tank Bottom Protector). IMPORTANT: Remove all chips and shavings out of the cut end of the tube. DO NOT remove chips and shave Ings by dumping thru valve body. 7150-TOOLCT Tip to stop dimension must bei-3/16'to 1-1/4' Figure 11C STEP 12C: DRILL HOLES With the Inlet tube and 71 SO-TOOLCT in place, carefully drill a 3/16' diameter hole in the upper tube using the hole In the 71 SO-TOOLCT as a guide. The drill stop Is positioned so It will bottom out against the tool after the bit has drilled through the upper drop tube. If the stop Is positioned wrong either no hole will be drilled, ora through hole could potentially be drilled through the inlet tube. If no hole Is drilled return to step 11 C and check the stop dimension. If a hole is drilled through the inlet tube or Into the screw hole the assem- bly Is not salvageable. Drill (2) more holes In the two remaining guide holes. omu,o,y,.eca' ��a,y Figure 12C FOR STANDARD VAPOR TIGHT MODELS, PROCEED TO STEP 20 ON PAGE 14. FOR TESTABLE MODELS, PROCEED TO PAGE 13.
