15 <br />Unpaved surfaces require a minimum of 20" (300mm) cover of recommended backfill <br />material. <br />After pressure testing is complete, care must be taken to insure even distribution and <br />packing of the backfill material around the piping during the back fill process. Hand <br />shovel material around and over piping to insure correct spacing is maintained. Backfill <br />slowly. It is recommended to maintain test pressure during back fill process. See test <br />section. <br />Additional care should be taken when initially filling the piping system to insure that all <br />air is removed from the product piping prior to starting any pumps to prevent damage. <br />Be certain that the operating pressure of the pumping system does not exceed the <br />maximum operating pressure of the Co -Flex piping of 75 psi. <br />Periodic testing of both the primary and secondary sections of the Co -Flex system may be <br />performed at any time after installation. Periodic testing and/or re -tightening of the <br />Direct Connection fittings may be performed at any time. <br />MEASURING PIPE RUNS: <br />Co -Flex piping is available in 250 ft or 1000 ft sections. It may be ordered by the foot if <br />required. The greatest care is taken after manufacture to package and ship your piping to <br />insure against damage. Do not drag Co -Flex along the ground, step or place heavy <br />objects on top of the pipe. <br />Cold weather will affect the flexibility and fitting attachment. Leaving the pipe coils in <br />the sun prior to installation will make them more pliable and easier to handle. In extreme <br />cold weather, store the piping indoors, at room temperature before measuring, cutting and <br />terminating. When installing the Direct Connection fittings, pipe ends may be heated <br />prior to attachment. Do not kink pipe when handling !. Kinked pipe sections should <br />not be installed !. <br />
