Site Preparation
Excavate the area for channel placement wide and deep enough to accommodate the standard channel size and a minimum of 4" concrete encasement on both sides as well as underneath the channel. Channels require a minimum of 4" of concrete support and top of channel must be evenly aligned with the surface of the surrounding slab.

Installation
Channel sections are installed from the outlet end of the system, working from either catch basins or deeper channel sections to shallow channel sections. Insert channels from above to allow ends to interlock. Channel sections shall be suspended to obtain correct finish height. Cutting will be performed with all purpose metal cutting saw or appropriate tool. Temporarily place expanded polystyrene block sidewall supports inside channels to avoid compression by concrete pour.

Concrete Pour
Protect channel interior during pouring of concrete. Place concrete in a manner that will not dislodge the channels. Concrete shall be at finished level or 1/8" above the top of the channel to ensure efficient drainage and adequate channel edge protection.

Finishing and Clean up
Following final set of concrete, remove channel protection, place grates in final position and engage locking bolts in correct location.
