1.0 System Overview The Thermaco, Inc. Trapzilla® Supercapacity Grease Interceptor collects free-floating grease & oils contained in kitchen drain water flows. As most food service facility managers already know, grease buildup inside a building’s grease containment system is a major cause of problems due to exterior drain line blockages. These problems jeopardize normal operations as well as create health and safety hazards within the facility itself.

Trapzilla® Grease Interceptor Installation and Operations Manual TZ-160, TZ-400, TZ-600 Models 3.0 Plumbing Installation 3.1 Plumbing Considerations Prior to Installation 3.1.1 Locating the Unit The system should be visible and easily accessible for maintenance and inspection. Options are available to install the Trapzilla in a basement, suspended from a ceiling or in-ground in an exterior location. Make sure adequate room is provided around the unit to allow easy access for a pump truck operator.
3.2 Vessel Vent Connection Venting of the Trapzilla tank is recommended by the manufacturer and required for indoor installations. • Vent the tank through the provided 2” NPT threaded connector on the side of the tank (This vent may be located above the outlet or on the side of the tank depending on model). • Remove and discard the 2” plug and connect 2” vent lines as indicated below.
Trapzilla® Grease Interceptor Installation and Operations Manual TZ-160, TZ-400, TZ-600 Models 3.3 Plumbing Configurations 3.3.1 Installing One Trapzilla Unit Each Trapzilla unit is shipped with a Low Head Flow Control module (see LHFC box for additional instructions). This needs to be installed to the inlet of the Trapzilla and connected to a code-approved air intake. Thermaco, Inc.
3.3.2 Installing Two Trapzilla Units in Parallel Two Trapzilla Grease Interceptors should be installed in parallel with a Flow Splitter diverting the flow. Place Two-Way Cleanouts before, between and after the units as shown below, including before and after the flow splitter. Make sure to connect an outlet vent after each Trapzilla Grease Interceptor. A Low Head Flow Control (LHFC) is shipped with each unit, and if needed should only be installed after the first Cleanout and before the Flow Splitter.
Trapzilla® Grease Interceptor Installation and Operations Manual TZ-160, TZ-400, TZ-600 Models 3.3.3 Installing Two Trapzilla GI’s in Series or One Solids Separator and One Trapzilla Alternatively, two Trapzilla Grease Interceptors 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.
3.3.4 One Solids Separator and Two Trapzilla Units A single Trapzilla Solids Separator and two Trapzilla Grease Interceptors should be installed by placing the Solids Separator in line and then using a Flow Splitter to divert the water flow to two separate Trapzilla units in parallel. Place Two-Way Cleanouts before, between and after the units as shown below, including before and after the flow splitter. Make sure to connect an outlet vent after the Trapzilla Grease Interceptor.

4.0 Above-Ground Installation 4.1 Components for Above-Ground Installations Using a model-specific Support Stand, a Trapzilla unit may be installed directly on top of the floor in a location such as a basement or mechanical room. TZ 400 or TZ-600: SSOP-400/600 TZ-160: SSA-160 *These items ship with all -SSA models. TZ-600 Trapzilla Basic Model NOTE: SUPPORT STAND MUST BE INSTALLED OVER A CONTINUOUS SURFACE.

Trapzilla® Grease Interceptor Installation and Operations Manual TZ-160, TZ-400, TZ-600 Models 4.2 Installing Multiple Trapzilla Units in Series When installing multiple Trapzilla units in series, the change in elevation from the inlet to the outlet of a unit requires that each preceding unit be installed 1” higher than the unit after it. For above-ground units, pressure treated plywood may be placed fully beneath the support stand to create the height difference.
5.0 In-Ground Installation 5.1 Plumbing Instructions for Single Trapzilla Installed In-Ground A Trapzilla unit may also be installed in the ground outside of the facility. For instances where the facility drainage piping requires an extension collar that is no more than 18”, use the instructions for the full TZ-600-ECA unit. If the unit is to be deeper in the ground, the ECA-TZ-29 Extension Collar Assembly may be installed to align the Trapzilla inlet with the drainage piping.

In-Ground Installations inside of a building must have a vessel vent installed and piped to atmosphere.
5.3 Trimming and Setting the ECA-TZ-18 Single-Piece Extension Collar In-Ground Trapzilla Models ship with a built-in, single-piece, 18” extension collar that must be trimmed and then set to the correct height to bring the Solid Top Cover to grade.

7.0 Measuring Grease/Solids Levels Due to its unique design, Trapzilla is capable of retaining high quantities of grease in a compact footprint. Therefore, unlike traditional interceptors, Trapzilla can hold an extraordinarily high percentage of its volume in grease without losing separation efficiency. To determine the current levels of grease/solids in your Trapzilla grease interceptor, follow the instructions below. 1. Remove four nuts/washers securing the Solid Top Cover.
Trapzilla® Grease Interceptor Installation and Operations Manual TZ-160, TZ-400, TZ-600 Models 8.0 Unit Maintenance Periodically, the Trapzilla® unit will need to be serviced which involves pumping out the accumulated grease & solids.
