Backfilling. Use only fine, 1/8" to 3/4" pea gravel or 1/8" to 1/2" washed, crushed stone as backfill around the
access riser. Do not use sand or native soil as backfill. Tamp backfill lightly. Avoid running heavy equipment next to
the riser. A light layer of topsoil can be used at cover level.

Installation of cover. The cover features a twist-lock design and 4 stainless steel screws to secure it. When
installing the cover, line up the four tabs with the four receptacles and locking tongue which fits into a cut recess in
the under side of the cover. Push down and rotate the cover in a clockwise direction until the tongue bottoms in the
slot. Install the four stainless steel bolts to secure the cover. A padlock can be placed through a hole in the tongue
to deter unwanted entry. The cover is designed to handle light traffic loads such as walking or light lawn and garden
equipment. DO NOT RUN HEAVY TRACTORS OR OTHER EQUIPMENT OVER THE COVER. MAXIMUM LOAD
