3.3.3 Installing Multiple Trapzilla Units in Series
Alternatively, two Trapzilla Grease Interceptors, Solids Separators or a combination may be installed in
series. A single Trapzilla Solids Separator and Trapzilla Grease Interceptor should always be installed
in series. Place Two-Way Cleanouts before, between and after the units as shown below. Make sure
to connect an outlet vent after the Trapzilla Grease Interceptor. A Low Head Flow Control (LHFC) is
shipped with each grease interceptor and should only be installed after the rst Cleanout and before
the rst grease interceptor.

Using a model-specic Support Stand, a Trapzilla unit may be installed directly on top of the oor in a
location such as a basement or mechanical room.

units come with built-in 18” Risers which must be cut down and secured in eld.
The External Brace must be installed in above-ground installations or the warranty will be voided.
