length in the field. Runs can be configured and supplied in any even 12" increment.
Standard channel sections for extended runs are 48" long.
Dead Level systems are generally installed on grade, poured in a concrete slab.

The flanged joints connecting channel sections are not watertight, and are typically
left unsealed by the installing contractor. Please contact your Watts representative
for above grade installation options, or if sealed joints are required by specification

Pre-Sloped Dead Level
Installation
1.) Dead Level
the channel sections attached to the frame sections. The system is designed
to be installed with the frames attached to the channels, do not separate the
channels from the frames. If the channels and frames accidentally become
separated, please contact your Watts representative for assistance.
2.) An installation diagram is supplied matching each configured run to the
corresponding assembled sections, which are sequentially labeled. The
installation diagram is normally packaged with the system hardware. If you
cannot locate the diagram, please contact your Watts representative for a
copy.
3.) Excavate a trench to allow a minimum 4" concrete pour below and on both
sides of the trench drain, and below a catch basin (if used).
4.) Work from the deepest outlet connection or catch basin back upstream.
Referring to the installation diagram, lay the trench drain sections alongside
the open trench. Each channel and frame is marked with arrows indicating
the direction of flow; confirm all arrows are pointing downstream.
5.) Establish an accurate line and grade reference using a string line or laser
level.
6.) Dead Level
equivalent all-thread rod. Starting from the outlet or catch basin (see Catch
Basin Cutouts), set the first section in place. Drive a minimum of 4 anchor
rods through the frame ears for each section. The required depth of anchor
rods varies with soil conditions; rods must be solidly anchored to provide
stability for the system, and prevent shifting or floating during the concrete
pour.
7.) Level each section by sliding the frame ears along the anchor rods, and
secure the frame in place with 3/8" hex bolts.
