Do not install this unit in any manner 

except as described in these instructions.

Doing so may result in property damage, personal injury or death.

DO NOT AIR TEST UNIT OR RISER SYSTEM! 

For Schier Grease Interceptor 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).

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. 

ODOR ALERT!

Do not install air 
gap on outlet side 
of interceptor.
