Support Piping, Equipment and Accessories
RISK OF SERIOUS INJURY OR DEATH

Using the basin to support any loading carried or created by
piping, equipment, cribbing, bracing, or blocking is never
permitted.
Provide support for piping, equipment, and other accessories
during backfilling. During backfilling, temporary support must be
carefully installed and removed to prevent damage to the basin,
piping, and/or equipment.
Anchorage
When basin installations are located in areas subject to high water
tables or flooding, make provisions to prevent the basin, either
empty or filled, from floating. The buoyancy force to be offset is
determined primarily by the volume of the basin. The principle
offsetting factors include:
• Backfill materials
• Concrete hold-down pad
• Friction between the basin, backfill materials, and
surrounding soil

Optional lifting lugs
Slope and size of excavation as per
OSHA and engineer’s specification.
In the absence of these,
consider condition of soil, depth of
excavation, and safety considerations.

Compacted sub-base and/or concrete
slab as per engineer’s specification

per engineer’s specification
CAUTION
:
HANDLE WITH CARE
Do NOT drop
Do NOT impact
Do NOT roll
Do NOT wrap cable or
chain around basin
Compacted sub-base minimum 12” or 6”
when used with concrete hold-down pad
Adjacent structure, foundation,
footing, or property line
In the absence of building codes or
regulations, maintain a minimum distance
of 5 feet plus a slope of 45° from the
bottom of the compacted sub-base to the
bottom of the adjacent structure’s
foundation, footing, or property line.
NOTE:
The intent of these installation instructions and illustration is to ensure that damage or
premature failure to the basin does not occur. These installation instructions and illustration are
not
intended to preclude normal safety procedures that should be followed to prevent injury to personnel.
SAFE INSTALLATION PROCEDURES ARE ENTIRELY THE RESPONSIBILITY OF THE INSTALLER
