Installation Instructions 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 ,ii I conformance with all local codes. Install interceptor as close as possible to fixtures being served Provide at least 12" clearance above unit for routine maintenance. High Temperature Kitchen Water — — 12" min. cold water supply line high temperature effluent (> 150° F) approved backflow prevention assembly DTV (drain water _ tempering valve) directly connected I indirectly connected If water is entering the interceptor at excessive temperature (over 150° F), a drain water tempering valve (DTV) and approved backflow prevention assembly must be installed. Most state and local plumbing codes prohibit water above 150° F being discharged into the sanitary sewer. Water above 150° F will weaken or deform PVC Schedule 40 pipe, poly drainage fixtures like interceptors and erode the coatirg 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 When Installing Interceptor Inside 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 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. pipe supports Bill— Fully Support Base of unit Install unit on solid, level surface in contact with the entire footprint of unit base When Installing Interceptor Inside 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.
