INSTALLATION
ACT 100S
The Head Works box is designed to minimize installation time. All hydraulic
connections occur on the underside of the Head Works platform. The figure below
shows the platform on its side. All the piping is secured to the platform, so there is no
need to provide additional support for the filtration and distribution system.
The pipe ends range in size from 1” to 1 ¼”. An elbow should be attached to each pipe
end. Prior to gluing the installer must decide which direction the outgoing and incoming
lines must go. Align each elbow and complete the gluing operation pointing the elbow
in the appropriate direction. Next install short pieces of pipe to each elbow so the end
of the pipe extends about 2” from the edge of the platform.
Prepare the site for the head works platform. The unit can be installed so that it sits on
the ground surface, is partially buried or fully buried. DO NOT cover the top of the head
works box. The unit requires occasional maintenance and must be left at or above the
finished grade. Be careful to set the final grade of the top of box so that grass and
surrounding soil do not cause water to run into the box, which will make future
maintenance difficult.
It is important to determine the installation depth of the piping prior to placing the head
works box. Once the depth has been determined the installer should excavate the area
to hold the headworks box plus an additional 4” to 6” below the intended platform level
and an additional 3” around the edge. The footprint would be approximately 34” x 45”
x +4” to +6 “deep. This area should then be filled with sand or pea-gravel.
