 Installation of Jay R. Smith Mfg. Co. Enviro-FloŽ Drainage Systems is achieved by following these basic steps. (An Enviro-Flo® Installation Guide is available upon request). Excavate a wide and deep trench to accommodate the channel and bedding concrete. Erect a temporary string line at each end of the drain run as a guide for laying the channels to the required level. Using appropriate installation device, begin channel installation at the evacuation or discharge end of the run where the catch basin or outlet is located. (Fig. A) Successive channels should be installed in order to ensure the top edge of the channel follows the string line. It is important that the arrow molded on the channels always point to outlet or catch basin. (Fig. B) The final channel in the run may require cutting to length. End plates are then placed in position and backfilled with concrete. (Fig. C) The depth of the bedding concrete should be a minimum of 4" or slab thickness, whichever is greater. Jay R. Smith Mfg. Co. Enviro-FloŽ Drainage System channels are shipped from the factory with 3/4" insert board in the grate seat. The insert board should be left in place when pouring concrete to prevent splashes and debris from entering the drain interior, and to maintain the correct grate seat width. (Fig. D) For drain channels laid in concrete floors, expansion joints must be provided parallel to each side of the drain run. Jay R. Smith Mfg. Co. also recommends placing crack control joints at right angles to the channels. Line up these joints with the joint lines of the channels. (Fig. E) For a monolithic pour use the Rante-Arrow installation device shown in (Fig. F). Please refer to the Enviro-FloŽ Installation Guide for detailed instructions.
