Dispenser Containment Manual 5.2 One Piece Dispenser Sump Assemblies Both deep and shallow dispenser sumps may be used for FlexWorks piping systems using coax and swivel couplings & fittings. Follow these installation instructions for this application: 5.2.1 Sump Height Adjustment The easiest means of adjusting the pipe entry height is to install the flexible entry boot at a higher entry level in the sidewall of the sump. Step 1: Install anchor bolts at required hole locations. Step 2: Locate and install Flexible Entry Boots in sump side panel. Step 3: Install Stabilizer Bars to the side struts. Step 5 Step 3 — "/ Step 8 —� I Step 6 Step 2 L Step 4 ro I /Step 1 Step 7 Step 4: Install Shear Valve Mounting Plate to the Shear Valve (if required). a? 0 N Step 5: Attach the riser pipe to Shear Valve. Step 6: Install Shear Valve to Stabilizer bar. Step 7: Install Conduit Entry Boots into side of sump. Q 5.3 One and Two Piece Poly and Fiberglass Sumps Fiberglass dispenser sumps are available in one piece, or 2 piece widemouth design for easy connections of pipe couplings and fittings. 5.3.1 Assembly of the Fiberglass Dispenser Sump Step 1: Locate flexible entry boot centers and install boots in the side wall of the base. Refer to the flexible entry boot installation manual for proper installation of the boot. I i Step 2: Insert sections of piping through flexible entry boots and attach to fittings inside the dispenser sump base. Step 3: Install stabilizer bars to dispenser sump riser frame. Attach shear valves to stabilizer bars. Install anchor bolts to the dispenser sump frame.

The stabilizer bars and valve plate assembly are designed to provide multi -directional side-to-side positioning of the shear valve as well as providing up to 1" of up and down movement. This will greatly assist in the connection of the shear valve to the product dispenser. 6.1 Tighten Down Fasteners Once all the shear valves have been connected to the inlet fittings of the product dispenser, all stabilizer bars and valve plate fasteners must be securely tightened. Make sure all spring nuts are in absolute horizontal alignment prior to final tightening of the bolt fastener. WARNING: Failure to properly secure stabilizer bar and valve plate fasteners could prevent the shear valve from activating in the event of a dispenser knock -over. 7.0 FLEXWORKS SYSTEM MAINTENANCE The FlexWorks System is designed to provide reliable underground fuel transfer and short-term secondary containment of leaked petroleum product. FlexWorks sumps and secondary containment pipes are not intended for long term storage of petroleum products. Liquid that accumulates in the secondary containment system must be promptly removed and properly disposed of. Operational third party approved liquid sensors should be installed and maintained in each sump to reliably indicate to the operator that liquid is present in the secondary containment system. Once a leak is detected, the system must be shut down immediately and the source of the leak must be repaired. All liquid must be thoroughly flushed and cleaned out of the secondary containment system at once. Inspect all system components at least monthly for leaks or damage, and repair or replace any suspect component as necessary. 7.1 ROUTINE SUMP INSPECTIONS Visual inspections of all containment sumps and components should be made on a routine basis to check for damage, water infiltration or for any signs of leaking product. An electronic or mechanical shut-off leak detection system is recommended for all containment sumps. When changing fuel filters at the dispenser, make sure any spilled product is cleaned out of the bottom of the dispenser sump. Sumps are to be kept free of debris and spilled fuel. NOTE: Failure to remove fuel and liquids from containment sumps may compromise the performance and integrity of the sump and its associated fittings and seals over prolonged periods of time. 8.0 GUIDE SPECIFICATIONS The following specifications are provided as general guidelines to specify under dispenser containment: 8.1 Short Form The contractor shall provide liquid -tight dispenser containers located under each fuel dispenser as manufactured by OPW- FCS. Containers shall house and permit access to the plumbing components located under each product dispenser. Containers shall be installed in accordance with manufacturer's
