Pipe installation instructions. 13.8.2 Insert Pipe into Sump Align the Access Pipe conduit/ flexible piping with the Access Pipe entry boot. Push piping through entry boot and attach coupling to the fitting using the methods described in section 14. 13.8.3 Insert Access Pipe into Boot Align the Access Pipe with entry boot and push into place until duct bottoms out. Tighten band clamps to 30 in. Lbs. 13.8.4 Installation of Duct with Coax Fittings Step 1. Drill entry boot holes using the appropriate size hole saw. Step 2. Measure and cut the length of Duct to be installed. Sump wall to sump wall plus four inches (4"). It is recommended to snake the pipe from side to side within the trench to compensate for expansion and contraction characteristics of the pipe. Step 3. Insert the outside portion of the Duct boot into the sump wall. Loosely install the Duct into the boot and measure from the face to face of the pre-installed Coax tee or elbow fittings within each sump. Cut the Flex flexible piping to this measurement with an OPW-FCS pipe cutter. DO NOT COUPLE THE PIPE. Step 4. Using a Barbed Bull Nose fitting (FBN-3150 or FBN-3200), insert the Flex piping through the section of Duct. It is recommended to start with the longest runs so if a mistake is made, the section can be used on a shorter section of the site. Step 5. In the following order, prepare the pipe to be coupled. 1. Place the outside portion of the Access Pipe boot over the Duct, studs pointing towards the end of the pipe. 2. Slip the black boot stiffener over the Flex and into the end of th e Access pipe. 3. Slide the inside "nose" portion of the Access Pipe boot onto the end of the Flex pipe. Be sure the smaller opening of the boot is towards the pipe end. Step 6. Coupling the Pipe. With the pipe still inside the Access Pipe, raise the entire assembly over the OPW-FCS coupling machine with a Coax coupling in position on the machine. Be sure the Flex pipe is vertical at the end and enters the Coax Coupling squarely then couple the pipe. Repeat steps 5 and 6 on the other end of the pipe section. Step 7. Insert the pipe assembly and boot nose through the pre -drilled hole in sump. The nose of the boot is flexible and can be folded. Use soapy water if needed. 14 F/exW(DR KS BY OOW FUELING CONTAINMENT SYSTEM® Step 8. Prior to installing the Coax coupling to the fitting, place the compression ring of the boot over the coupling end of the pipe and complete the installation of the Access Pipe entry boot. Tighten all compression rings in a clockwise pattern not exceeding 60 in/lbs. If sealant is used on the outside portion of the entry boot, it should be applied during this step. Step 9. Fully insert the Access Pipe and black stiffener into the Access Pipe Entry Boot and install all band clamps. Do not exceed 30 in/lbs on band clamp assemblies. Step 10. Repeat steps 7 through 9 on the other end of the pipe. You may need to compress the Access Pipe in an accordion fashion when installing the Access Pipe at the end of the procedure. Air test Access Pipe if desired. 14.0 PIPING CONNECTIONS After all containment sumps have been interconnected with all of the flexible pipe sections, all riser pipe assemblies and test boots (if required) have been installed, then all piping connections may proceed. There is a different installation procedure for each type of piping connection. Comply with the following connection procedures for each type. 14.1 Coaxial Coupling Connections Coax couplings do not require the use of any tools for tightening. The following connection procedure needs to be followed for proper installation: 14.1.1 Coupling Inspection Prior to connection, inspect coupling to make sure all rubber O -rings are properly in place and seated inside the O-ring grooves. Look for any dirt or damage to the O -rings which may have occurred during the coupling procedure. Coax nut must be fully seated for proper connection. 14.1.2 Fitting Inspection Remove the plastic protective cap from the fitting or adapter. Inspect the fitting or adapter to be sure that it is free of sand or debris in the core area and on the threads. 14.1.3 Tightening Coax Nut Push the pipe coupling onto the core of the fitting or adapter and hand tighten the coax swivel nut onto the threads of the fitting. Be sure that the piping does not twist while hand tightening, and verify that upon tightening, no threads are visible. NOTE: Tighten by hand only until coupling bottoms out into fitting. Do not continue to tighten the nut once the coupling has stopped.
