Leak/Seal Testing
DO NOT AIR TEST UNIT OR TELEGLIDE RISER SYSTEM! Doing so may result in property damage, personal injury or death.
Base Unit: To perform a leak/seal test on the base unit, cap/plug all plumbing connections, remove the cover, and fill the unit with water just above the
highest connection. Inspect unit and connections for leaks. Check water level at specific time intervals per local code.
TeleGlide Riser System: If required by local code, the riser system may be leak/seal tested similar to the base unit. CAUTION: the riser(s) must be supported
before filling with water to keep from tipping over. Once riser system is in place and properly supported, cap/plug all plumbing connections on the main unit,
remove the cover from the top of the riser assembly and fill the unit and riser system with water to finished grade level. Carefully, as the riser(s) will be very
heavy from the weight of the water, inspect all gasket(s) and clamps (if applicable) for any leaks. Check water level at specific time intervals per local code.

Certified Performance
Great Basin hydro mechanical grease interceptors are 3rd party performance-tested by NSF and listed by IAPMO to the ASME #A112.14.3 grease
interceptor standard (Note: GB-125 is not listed, but is factory-rated), greatly exceeding requirements for grease separation and storage. They are compliant to
the Uniform Plumbing Code and International Plumbing Code. Models GB-75 and GB-250 have been approved by most municipal pretreatment authorities as
equivalent to larger, less efficient gravity grease interceptors.

NOTES:
Schier grease interceptors are rated and manufactured with an internal flow control system already in
place. They do not require an external flow control system or air intake vent.
Schier grease interceptors are not to be installed in any other manner except as shown. Consult local
codes for separate trapping requirements, cleanout locations and additional installation instructions.
MAINTENANCE
Remove cover(s). 1.
Remove all contents of the grease interceptor including grease, sediment and wastewater. For most 2.
thorough cleaning contact a professional pumper contractor.
To access the inlet and outlet lines for cleaning as needed: 3.
a.) 4" connections: Remove the inlet and outlet diffusers (inside unit(s)) by hand loosening
green locking collars.
b.) 6" connections: Remove threaded clean-out plug from the back of the inlet and outlet diffusers.
Clean the drain lines, diffusers and air relief thoroughly of all debris before replacing diffusers to 4.
original positions or reinstalling threaded clean-out plug.
Run sinks to fill unit(s) with water. 5.
Inspect gasket for wear and tear. Replace cover(s). 6.
Dispose of grease per local code. 7.
PUMPING FREQUENCY:
Frequency depends on the capacity of the interceptor and the amount of grease and sediment in the
wastewater.
Monitor each pumping to establish an adequate maintenance schedule based off actual kitchen variances.
Levels can be tested with core sampler. Schier Products recommends pumping frequency to exceed no more
than 90 days.
OPERATION
Schier Products offers a complete line of grease interceptor tanks to separate fats, oils, and grease waste
from the waste stream and stops it entering the public sewer system.
Influent passes through the built-in calbrated flow control, where it is diffused into the main chamber. Lighter
grease is forced upward, heavier solids are forced downward. Effluent flows through the outlet, free of
grease and food waste.
Flow
GENERAL INTERCEPTOR INSTALLATION INSTRUCTIONS
(GB-250 SHOWN)
To test unit and TeleGlide riser system for leaks, cap/plug connections and fill unit
with water to covers. Inspect gaskets, fittings, and unit for any leaks.
If no leaks are detected drain water to the static waterline. Unit is now ready to be
backfilled and put into operation.
TROUBLESHOOTING TIPS:
In the case of a clog, inlet and outlet diffusers may be removed for line cleaning. Slower than usual sink
drainage may indicate the need to pump/clean grease interceptor.
Always take proper care to ensure a safe and healthy environment while cleaning interceptor. For best
cleaning and maintenance service, call your local sewer and drain contractor.

Riser Assembly Instructions/Steps:
If unit is to be installed on grade (on-the-floor), there is no need for any adjustments. 1.
Unit is ready to be put into service.
If unit is to be buried: Once unit is set so that the pipe connections line up with 2.
jobsite piping, measure total riser height needed from top of cover to finished
grade. Make sure you include any future tile work, etc. that may be installed
in your finished grade measurements. See figure 1.
Select according riser(s) needed based off Table 1. 3.
If riser(s) is needed, remove cover(s) from adapter and remove adapter from main 4.
unit by loosening upper clamp with included nut driver bit (lower band is factory
set do not adjust or remove). On the floor near the unit, insert adaptor into first riser
until it stops. If needed, insert bottom of first riser into top of second riser until it stops.
You may need to tighten upper clamps during this step to keep risers from shifting.
Adapter and riser(s) should sit level with each other. Removal of cover during this process
will ease assembly.
From the top of the adapter, measure your needed total riser height downward to the 5.
sidewall of the riser. Then, add 5”
(for GB-35 or GB-50) or 6” ( for GB-75, GB-125 or GB-250).
For example, if you have a GB-250 and need a 15-1/2” extension, you would measure
down from the top of the adapter 21-1/2” (15-1/2” + 6” = 21-1/2”). See Figure 2.
Refer to Table 2, Table 3 or Table 3a to determine if, and where, any cuts need to be made. 6.
If a cut needs to be made, make a circular line around the sidewall of the riser with the
included silver marker at your riser height +dimension from step 5 . Using a jigsaw, circular
saw or reciprocating saw, cut along your line. Discard/recycle the cutoff scrap.
Whether the riser needs to be cut or not, make another mark with the silver marker on the 7.
sidewall of the riser a distance of 4 INCHES (3 INCHES for a GB-35 w/ 4” connections) above
the edge just cut. If you did not make a cut (meaning your riser height + dimension from
step 5 line was beyond the bottom edge of your riser), still mark the sidewall of the riser
4 INCHES above where your riser height + dimension from step 5 line would have been.
DO NOT cut this new line. Once the riser is installed into the main unit, this new line will end
up at the top of the gasket and will aid in re-assembly. See Figure 3.
IMPORTANT: Before the next step: 8.
Make sure both diffusers are installed inside the main unit at the appropriate locations 1.
and check if there needs to be any flow control adjustment on the inlet diffuser. Refer
to sheet 2 of the installation instructions for flow control adjustment.
Refer to sheet 1 of the installation instructions for leak/water testing procedures. 2.
Take riser(s) and adapters apart to reduce the weight during installation. Wipe all sidewalls and 9.
inside of gasket with a damp cloth to remove jobsite dust/debris. Install components into the main
unit starting from the lowest (cut) riser and working your way toward the finished floor level. Upper
clamps at each gasket need to be loosened or removed to aid in assembly. Once riser(s)/adapter
is inserted into gasket, upper clamp can be tightened.
Verify that the bottom of the lowest riser is protruding at least 2-1/2” but no more than 4” into 10.
the main unit from the top of the gasket. Your mark from step 7 should be at the top edge
of the gasket on the main unit. If measurements were made correctly, this should happen
automatically. See figure 4.
If tilting of the adapter is required to be flush with finished grade, it must be done AFTER all 11.
clamps have been tightened with riser(s)/adaptor in a vertical and level position. Tilting is
achieved by using the flexibility of the gasket. If tilting is done before clamps are tightened, a
perfect gasket seal may be compromised. Schier recommends tilting only the adapter versus the
entire riser assembly to make sure your riser height is maintained.
Tighten all clamps to a minimum of 5 and a maximum of 8 ft lbs. of torque. Use the same torque 12.
as you would tighten a rubber no-hub coupling.
The adapter must be adjusted upward to achieve certain extension heights. See Table 2, 13.
Table 3 or Table 3a.
If jobsite riser height conditions change after the above steps have been completed, there 14.
may still be room for vertical adjustment in both directions. As long as minimum and maximum
overlaps are maintained (see Figure 4), the adapter/riser(s) can be adjusted/cut as many times
as necessary. Please follow these steps from the beginning to ensure the proper overlaps are
maintained.
NOTES:
Schier grease interceptors are rated and manufactured with an internal flow control system already in
place. They do not require an external flow control system or air intake vent.
Schier grease interceptors are not to be installed in any other manner except as shown. Consult local
codes for separate trapping requirements, cleanout locations and additional installation instructions.

Riser Assembly Instructions/Steps:
If unit is to be buried, you will need an SR16 riser kit (sold separately). The 16 Series TeleGlide Riser System for these 1.
models allows riser heights from 2-1/8" above standard unit up to 16". Only ONE riser may be used per base unit to allow
sufficient access to internal serviecable components. See Figure 5.
If more than 16" of riser height is needed, you will need to adjust jobsite requirements OR purchase the next available 2.
model with a 24 Series TeleGlide Riser System which allows taller riser heights.
Once unit is set so that pipe connections line up with jobsite piping, remove cover from unit. Fasten yellow gasketed ring to 3.
unit with hardware provided in separate riser kit. Ring flange with 4 bolt notches faces down against the unit. See Figure 1.
Push riser into ring until it stops (about 1 inch). See Figure 2. 4.
Measure the distance from the top edge of the riser down to the finished floor. Make sure to account for any future tile work 5.
in your measurment. See Figure 2.
Remove riser from ring. Take measurement from step 5 from the BOTTOM of the riser upwards towards the top of the 6.
riser. Mark a line around the riser, and cut with handsaw, jig saw, or reciprocating saw. Remove debris from cut edge with
scraper, utility knife, or gloves. See Figure 3.
Place cut riser back into ring on unit until it stops. Fasten cover from unit into riser with the same 4 bolts from the unit. Unit 7.
is ready to be water tested and backfilled. Install finished floor. See Figure 4.
NOTES:
Schier grease interceptors are rated and manufactured with an internal flow control system already in
place. They do not require an external flow control system or air intake vent.
Schier grease interceptors are not to be installed in any other manner except as shown. Consult local
codes for separate trapping requirements, cleanout locations and additional installation instructions
