SPECIAL PRECAUTIONS
AGS2
The wet weight of the interceptor combined
with high temperature kitchen water
creates the potential for tank deformation
when installed above grade. Model GB-500
installed above grade must be installed
with Above Grade Support Kit model AGS2
to maintain structural integrity
Above Grade Installation Support
(for Model GB-500 Only)
Install unit on solid, level surface in
contact with the entire footprint of
unit base; for suspended
installations design trapeze to
support the wet weight of the unit.
Do not partially support unit or
suspend unit using metal
U-channel to create a trapeze.
Fully Support Base of Unit
For above grade installations ensure
heavy inlet and outlet piping (such as
cast iron or long runs) is properly
supported or suspended during the
entire installation process to prevent
connection failure or damage to
bulkhead fittings.

High Water Table Installations
Interceptors
and risers are not designed to
withstand water table height in
excess of the top of the unit when
buried (see figure). If it is possible
for this to occur, install the
interceptor and risers in a
water-tight concrete vault or
backfill with concrete or flowable
fill (wet concrete and flowable
backfill should be poured in stages
to avoid crushing the interceptor).
At risk areas include but are not limited to tidal surge areas, floodplains
and areas that receive storm water. Great Basin™ models that are direct
buried in high water table scenarios must be installed with an anchor kit.
Model GB-500 uses model AK1 anchor kit.
