2 Polyethylene Dispenser Sump Preparation If required, the sump riser can be cut down in height, leaving 25 mm (1") rain-lip above the frame, and the mounting frame repositioned by drilling and re-bolting in the new frame positions. Mount the Stabilizer Bars Mount the Dispenser Sump 1. Make sure the top of the sump mounting frame is flush with the finished island surface. 1. Undo mounting bolts. Hold stabiliser bar in position and check the number of spacer plates required on each side. 2. Secure the sump with wood or angle iron or directly to the island form. Most commonly the sump is set into concrete to position it correctly. 3. Mark the pipe entries for product and vapour lines for the appropriate dispenser model. 4. Mark the correct entry height to allow correct fall (normally 1 m per 100 m or ¼ - ⅛ inch per foot) to the Underground Storage Tank (UST). 2. Place channel nuts in unistrut at approximately the correct location on each side of the sump and rotate the nuts 90º. Assemble one side of the stabiliser bar: Pass bolts through holes in stabiliser bar, and through spacer plate(s) if required. 5. Install any UPP entry seals according to their specific Instructions. Note: UPP electrofusion entry seals can be installed before mounting dispenser sumps. Sump assembly sequence is flexible. 2

Insert bolts through stabiliser bar and plate(s) and into the channel nut. Hand tighten bolts. d L T or Calculate appropriate length for riser from the PE Riser Table. 4. Attach and complete all internal sump pipe-work (including shear valve assembly). Tighten bolts fully once shear valves are correctly located. Assembling a Polyethylene Riser 1. Assemble transition fitting into shear valve (emergency shut-off valve). L S 2. Assemble welding coupler, riser and mounting plate to shear valve assembly. 2. Measure length of shear valve assembly from shear plane to end of transition spigot, L S. PE Riser Table 50 mm (2") 63 mm (2.5") L T + 126mm [5"]) L T + 150mm [6"]) + 32mm [1.5"]) + 40mm [1.6"]) d = Depth of Entry Seal from grade. L S = Length of Shear Valve Assembly. L T = Length of PE Riser required for Tee arrangement. = Length of PE Riser required for Elbow arrangement. 3. Hang shear valve assembly. Connect and weld to mating pipe-work. 3

4 Polyethylene Dispenser Sump Installation Completion 1. Tighten all bolts. Ensure shear valves are in correct position. Tighten all stabiliser assembly bolts in their final positions. Refer to the shear valve manufacturers instructions for product specific information. 2. Electrical conduit Certain sump frames are pre-drilled with three holes, giving the option to route the conduit external to the sump but within the frame. Ensure holes are correct way around. For other sump models conduit seals will have to be installed as they do not have pre-drilled frame holes. 3. Inspection / Maintenance UPP dispenser sumps are designed to provide secondary containment of dispensers and piping or connections. Sumps must be regularly inspected and checked for the presence of petroleum products. Any liquid detected must be removed promptly and disposed of correctly and the cause of the problem rectified. Long term presence of petroleum products in sumps would invalidate FFS s UPP System warranty. Flexi Risers if using flexible risers they should be constructed to the required height to maintain the correct pipe entry level. Final Backfilling for Sumps Backfill evenly around the sump with approved backfill material. Approved materials for dispenser sumps are the following Class I and II materials, per ASTM d-2321: Class IA materials include angular, open-graded, clean, manufactured aggregate that contain little or no fines such as crushed stone or crushed cinders or shells. Class IB materials include angular, dense-graded, clean, processed aggregate such as Class IA materials mixed with sand and gravel to minimize migration. Class II materials include clean, coarse-grained soils that contain little or no fines such as gravel, gravelsand mixtures, and well and poorly graded sands. Important: Do not over-compact backfill, or you may distort the sump. Shovel slicing (cutting the backfill with a shovel) is the recommended way to compact Class I and II materials. To improve compaction, slightly wet the backfill, but do not saturate the material or flood the trench. Important: If the underside of the chamber overhangs the tank containment collar, make sure you add enough backfill to support the underside of the chamber. Important: Backfill material should fully support UPP pipe-work and be free from ice or organic silt or peat, which could disappear over time causing voids or possible ground movement. No mechanical compactors should be used such as vibrating plates or road rollers. Tightness Testing Tightness testing must conform to local regulations. Hydrostatic Testing Procedure Fill the sump with water until the level is just above the connection to the shear valve. After 1 hour, if there is no bubbling or drop in water level, the sump passes the test. Vacuum Testing Procedure 1. Remove the top frame and fit the test lid. Make sure the pipe-work is plugged and not in communication with the sump volume. UPP System Integrity Testing Unit Test Lid 4 Vacuum Test Sump (Wide Mouth model shown) 2. Use the UPP System Integrity test Kit (VTU-115V or VTU-230V). Vacuum test to verify tightness of complete sump assembly. Follow tester instructions. 3. Recommended depth setting: 1 ft. Max. 4. Replace frame and fit shear valves.
