1. Clear debris from lip of manhole with crowbar or wire brush.
2. Install insert on lip.
3. Place 14” bottom screen over vent holes.
4. Spread 1” Media and place Diffuser Plate on top.
5. Fill with Media to the top.
6. Place 22” Screen on top and tuck sides under lip for best fit, then lay lifting straps over top.
7. Make indentations in Media for struts on bottom lid of manhole if necessary.
