❑ Make up the following assembly, see photo L. Note: The ball valve handle closes toward <br /> you. Install a 1/2" NPT x 5/8" flare straight fitting to the left side of the ball valve, install the <br /> 1/2" close nipple to the right side then the 1/2" reducing tee and the 1/2" NPT x 5/8" flare <br /> elbow — completely tighten the tee with the 1/4" branch facing up and the elbow also facing <br /> up, install the 1/4" pipe plug into the branch. <br /> ❑ Make up a piece of 5/8" OD copper tube that will go from the flare elbow on the inlet of <br /> the VAC pump, through the upper 1-1/8" hole in the column to the straight flare fitting on <br /> the ball valve assembly so that when installed and secured, positions the flare elbow on <br /> the ball valve assembly in a straight line with the straight flare fitting that's attached to the <br /> 3/4" elbow of the upper vapor manifold. Install and tighten with the ball valve assembly in <br /> position as shown in photo L. <br /> ❑ Make up a piece of 5/8" tube to connect the flare elbow on the ball valve assembly to the <br /> straight flare fitting that's attached to the 3/4" elbow of the upper vapor manifold. This <br /> piece should be made so that when installed the ball valve assembly and tubing should be <br /> horizontal or slightly pitched toward the pump to avoid liquid traps. Install and tighten. <br /> ❑ Mark the location of the mounting bolt holes from the VAC pump base on the shelf, unscrew <br /> the flare nut on the inlet and move the VAC pump out of the way. Drill two 5/16" holes (one <br /> on each side of the bracket) required for mounting the pump. <br /> ❑ Reposition the VAC pump and reconnect the flare nut to the inlet port, then install the two <br /> 1/4-20 bolts, washers, lock washers and nuts to secure the pump. <br /> 4= <br /> L <br /> i <br /> Photo M Photo N <br /> ❑ Measure and cut appropriate length of 5/8" tubing to reach from the 5/8" flare elbow on the <br /> outlet of the VAC pump, through the lower 1-1/8" hole in the column to the 5/8" flare straight <br /> fitting installed in the 3/4" elbow at the base of the dispenser, using a 90 degree bend, see <br /> photos M & N. <br /> ❑ Install and tighten making sure the horizontal portion of the tube attached to the outlet is <br /> either horizontal or slightly pitched downward away from the pump to avoid liquid traps. <br /> 8-10 <br /> CARE Approved IBM 8-Wayne Harmony Series(Assist)-Executive Orders VR-281 and VR-282 <br />
