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.

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.
