fitting/pipe coupling connection. Please follow the steps noted below: ® Install the stabilizer bars in their proper position, per OPW FCS Stabilizer Bar Installation Instructions, which can be determined by the dispenser manufacturer's footprint for the particular dispenser model. This will allow for proper vertical alignment. Install the shear valve to the shear valve mounting plate and secure this to the stabilizer bar in accordance with the dispenser manufacturer's footprint. Install the entry boots in accordance with the OPW-FCS Flexible Entry Boot installation instructions. • Line up the center of the entry boot with the center of the opening of the tee, elbow or adapter. • Determine the length of the steel riser by measuring between the bottom of the shear valve and the top of the tee, then add 1-1/2" to that length prior to cutting the NPT threads for each end of the riser. • Install the riser to the top of the shear valve with the use of soft set pipe dope that is approved for use with petroleum products. • Install the tee, elbow or adapter to the bottom of the riser, positioning it properly to align with the entry boot horizontally, with the use of soft set pipe dope that is approved for use with petroleum products. • Reinstall the riser set up to the stabilizer bar and then make sure that the tee, elbow or adapter opening is on center with the entry boot opening on both the horizontal and vertical plane. • Assure that the opening of the tees, elbows or adapters are all on center with the entry boot, on both the horizontal and vertical plane. 12.2 Non -Contained Riser Pipe Non -contained riser pipe assemblies are only permitted if they are to be installed inside dispenser sumps. These riser pipes assemblies may have a coax or swivel fitting installed at the base of the steel riser pipe. 13.0 FLEXIBLE PIPE FABRICATION After all plumbing trees have been installed inside the tank sumps and riser assemblies installed into either the deep or shallow dispenser sumps, fabrication and installation of the - ---.--- flexible piping may proceed. IMPORTANT. Only currently certified contractors with a valid factory training card are authorized to install Flex piping. 13.1 Pipe Handling At Jobsite Care must always be taken when handling OPW-FCS's flexible piping to prevent damage. It is recommended that the carton be placed in the sunlight several hours before measuring and cutting the pipe, so the pipe may relax for easier extension when measuring. 11 11 FheAWOORKS BY GPIN FUELING CONTAINMENT SYSTEMS WARNING:drag,or ;« pipe during 13.2 Cold Weather Pipe Handling OPW-FCS's flexible piping can be installed in ambient temperatures as low as zero degrees, provided that the flexible piping has been sufficiently warmed prior to unrolling. If the pipe is unrolled and straightened while it is warm, it will cool in a straighter position making it easier to install. For cold weather installations where the ambient temperature is below 400 F (50 C), it is recommended that the piping cartons be placed in a warm room for 8 hours directly prior to installation. If this is not possible, then a small hole should be cut in the top center of the lid of the carton for insertion of the nozzle of a conventional hair dryer. For piping reels, place a tarp over the reel and then insert the hair dryer nozzle directly into the end of the piping. If this pipe warming procedure is used, do not use the first 12" of the pipe due to possible damage by the hair dryer. Depending on the ambient temperature, it may take up to an hour to warm the roll of piping sufficiently. 13.3 Flexible Pipe Measuring When measuring the distance between containment sumps or pans to determine the proper length of a flexible pipe section to be installed, it is important to consider that the pipe is flexible and will not be installed perfectly straight. A slight weaving of the pipe in the piping trench is recommended to compensate for expansion and contraction. The recommended measuring and cutting procedures for the flexible piping are described below: 13.3.1 Direct Pipe Burial Applications When measuring for direct burial of flexible piping, the measuring points will be from the face of one adapter/ fitting to the next. If swivel couplings and fittings are used, subtract 1" to allow for the length of the two pipe couplings and cut the piping to that length. For coax application, no modification to the measurement is necessary. 13.3.2 Access Pipe Burial Applications For Applications using Access Pipe, measurements must be taken through the Access Pipe to insure proper length. Feed the measuring tape through the Access Pipe and measure the distance from the face of the one adapter/ fitting to the next. If swivel couplings and fittings are used, subtract 1" to allow for the length of the two pipe couplings and cut the piping to that length. For coax application, no modification to the measurement is necessary. See Access Pipe installation instructions for complete information and installation steps. 13.4 Flex Pipe Cutting When cutting the piping into pipe sections, cut the pipe at the measured cut mark using the pipe cutter tool. This cutting tool is designed to make clean and even cuts in the
