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.

DESCRIPTION: 34" Field Cut Riser System
PART #: 8010-006-01 DWG BY: B. Karrer DATE: 6/24/2020 REV: ECO:

Do not install this unit in any manner
except as described in these instructions.
Do not add any form of lubricant to cover adapter/
gasket assembly or risers during installation.
Make Sure Parts Are Clean When Applying Silicone or
Mastic Sealant
Doing so may result in property damage, personal injury or death.
DO NOT AIR TEST UNIT OR RISER SYSTEM!
SPECIAL PRECAUTIONS
For Schier riser Installations - Failure to follow this guidance voids your warranty
Installation Instructions
Installation instructions and additional components are included with
the base unit. Read all instructions prior to installation. This riser is
intended to be installed by a licensed plumber in conformance with all
local codes.

Pressure Slabs
When installed under a

by hydrostatic pressure)

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. Models that are direct buried in high water table scenarios must
be installed with an anchor kit. See base unit installation instructions for
selecting appropriate anchor kit.
Below Grade Installation Slab Requirements
A concrete slab to finished grade with rebar is required when
installing interceptor below grade.

SPECIAL PRECAUTIONS
For Schier riser Installations - Failure to follow this guidance voids your warranty
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).

ODOR ALERT!
Interceptor is not a
sewer gas trap.
All upstream fixtures
must be trapped
ODOR ALERT!
Do not install air gap on
outlet side of interceptor.
Fully Support Base of Unit
Install unit on solid, level surface
in contact with the entire
footprint of unit base
Support Inlet and Outlet Piping
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.

INSTALLATION
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.
