Engineer Specification Guide:
Field-cut adjustable riser system to consist of injection molded polypropylene
body, 100% Silicone Sealant for assembly of riser components, butyl mastic sealant
for tank-riser or riser-riser joints, stainless steel fastening hardware and heavy duty
nylon cable ties and mounts. Riser shall allow field adjustability of cover to grade.
Installation Note
Minimum install height: 4". Maximum install height: 34". Riser system may be
stacked no more than three units high to a maximum of 94" extension. Access to
internal components will not be compromised.

Interceptor
If water is entering the interceptor at excessive temperature (over
150º F), a drain water tempering valve (DTV) and approved backflow
prevention assembly must be installed. Most state and local
plumbing codes prohibit water above 150º F being discharged into
the sanitary sewer. Water above 150º F will weaken or deform PVC
Schedule 40 pipe, poly drainage fixtures like interceptors and erode
the coating of cast iron (leading to eventual failure).
Installation instructions and additional
components are included with the
interceptor. Read all instructions prior
to installation. This interceptor is
intended to be installed by a licensed
plumber in conformance with all
local codes.
If your dishwashing sink(s)
discharges into a floor
drain/sink (drain), you
must regulate the flow into
the drain to avoid an
overflow of water onto the
kitchen floor. This can be
done by installing a valve
or flow restriction cap on
the sink piping that
discharges into the drain.
See drawing for guidance. For detailed guidance on indirect
connections, go to:
webtools.schierproducts.com/Technical_Data/Indirect_Connections.pdf
When installed under a
hydrostatic slab (slab
designed to withstand
upward lift, usually
caused by hydrostatic
pressure) interceptor
must be enclosed in a
watertight concrete vault.

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.

For Schier Grease Interceptor Installations - Failure to follow this guidance

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. Models GB-50, GB-75,
and GB-250 use model AK1 anchor kit. Model GB-500 uses model AK2
anchor kit for use with deadmen anchors. Models GB-1000, GGI-750 and
GGI-1500 use model AK3 anchor kit for use with deadmen anchors.

Determine Trim Length (round up all fractions to next inch).
Only one FCR2 riser per cover will need to be cut.
NOTE: If trim length is 0 or less, no cutting is required. Trimming risers using
these guidelines will result in risers that are 0-2" shorter than the exact riser
height needed. Cover Adapter adjustability will allow for final adjustments
to grade.
