DIFFUSION FLOW TECHNOLOGY
The inlet diffuser splits influent into three paths, creating
laminar flow and utilizing the entire liquid volume of the tank
for efficient grease separation. The calibrated openings
greatly reduce effluent turbulence. The effluent enters the
main chamber without disturbing the existing grease or
sediment layers.
The integral air relief / anti-siphon in the top of the outlet
diffuser allows pressure stabilization within the unit during
operation. The bottom of the outlet diffuser allows only
effluent which is free of grease to exit the tank. It can easily be
attached to any of the three outlets provided to ease jobsite
piping layouts.

INSTALLATION
Vent
WARNING! DO NOT AIR TEST UNIT!
Doing so may result in property damage, personal injury or death.
LEAK/SEAL TESTING
Cap/plug all base unit plumbing connections and remove cover. Fill with
water to just above the highest connection. Inspect unit and connections
for leaks. Check water level at specific time intervals per local code.
GENERAL INSTALLATION INSTRUCTIONS
Schier grease interceptors are rated and manufactured with an internal
flow control system. They do not require an external flow control system
or air intake vent. Flow control plate may be removed when interceptor is
is installed less than 13 feet below the fixtures being served. 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.
1. Set unit on level solid surface as close as possible to fixtures being served.
2. Connect outlet diffuser to the desired outlet (A,B,C). Unit is shipped with
the outlet diffuser in location B and sealing caps on locations A and C.
3. Connect inlet and outlet drainage lines to unit. Mechanically couple pipes
to unit. Do not solvent weld. Roll down inlet line using (2) 45º elbows
immediately preceding the unit to ensure inlet pipe is clear of water.
4. To conduct a pressure test on the pipes, remove diffusers and fasten
green caps to the inlet and outlet connections. Do not pressure test unit.
Hand tighten inlet/outlet diffusers and caps back to chosen positions.
5. Run sinks to fill unit with water and replace cover.
BELOW GRADE INSTALLATION INSTRUCTIONS
If unit is buried, backfill with sand or pea gravel. Pour concrete and install
finished floor. Note: maximum extension dimension is 36"

INSTALLATION FOLLOWING INDIRECT CONNECTION
Installing a rubber cap with a 1/2" diameter orifice at the point of
discharge to the floor sink may be necessary to prevent overflow when the
flow control plate is installed.
MAINTENANCE
1. Remove cover.
2. Remove all contents of grease interceptor including grease, sediment
and wastewater.
3. To access inlet and outlet lines for cleaning, remove the diffusers. Clean
diffusers thoroughly before replacing to original positions.
4. Hand tighten inlet and outlet diffusers back to original positions.
5. Run sinks to fill unit with water and replace cover. Dispose of grease per
local code.
PUMPING FREQUENCY
Frequency depends on the capacity of the interceptor and the amount of
grease and sediment in the wastewater. After initial installation, it is
recommended that the unit is pumped every 3 to 4 weeks. Monitor each
pumping to establish an adequate maintenance schedule based off actual
kitchen variances.
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.
