INSTALLATIONS - GREASE INTERCEPTORS
SINGLE FIXTURE INSTALLATIONS
Fixture Not Trapped	Fixture Trapped and Vented Separately
Fully Recessed	Recessed with Extension to Floor Level
MULTIPLE FIXTURE INSTALLATIONS
It is sometimes practical to discharge the waste from two or more sinks into a single Interceptor. This practice is only recommended when all fixtures are close together, avoiding installation of long piping runs to the Interceptor. For multiple installations, size as follows: Determine total capacity of all sinks. Establish the maximum simultaneous discharge of the sinks and fixtures. Using the maximum simultaneous load capacity, determine the Interceptor required using the sizing method shown by clicking here.	On Floor Installation
Terminate Air Intake outside above the rim of sink with return bend or connect to vent or vent stack as required by local code.

GREASE INTERCEPTORS WITH EXTENSION INSTALLATION NOTE
The Extension of 8200 Series Interceptors is designed to increase the roughing dimension from the Inlet-Outlet center line to the finished floor. The Extension should not be used to support the entire unit. When installed in ground floor locations, the Interceptor body must rest on solid ground or on a suitable concrete pad. If the 8200 Series unit is installed in an upper floor (suspended in the ceiling below), a suitable method of supporting the entire unit must be provided. The installation sketch shows a typical Interceptor with Extension and a recommended method of supporting the entire weight.

SUSPENDED INTERCEPTOR INSTALLATION CONSIDERATIONS
Whenever an interceptor is to be installed suspended with receiving cradle (8300 series) or independently (all other series interceptors), proper support is essential for safety and functional integrity of the installation. Trapeze type hangers such as those employed for support of multiple runs of horizontal piping are recommended for support of independent interceptors. Such supports should also be considered for 8300 series receiving cradles to supplement the integral concrete anchor flange. Supports must be of sufficient strength for the purpose intended and meet with the approval of the architect or engineer.

DISHWASHER MACHINES
A separate grease Interceptor is recommended with each dishwashing machine. The size of the Interceptor is determined by the dishwasher capacity. Terminate Air Intake outside above the rim of sink with return bend or connect to vent or vent stack as required by local code.
