1.0 System Overview
The Thermaco, Inc. Trapzilla® Supercapacity Grease Interceptor collects free-oating grease & oils
contained in kitchen drain water ows. 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.
The proper installation of a Trapzilla®
Supercapacity Grease Interceptor can
reduce or eliminate grease problems and
costly sewer surcharges and nes through
efcient separation and retention of free-
oating grease & oils.
The Trapzilla offers patented flat separation
curve technology. This means that the unit does
not lose grease separation efciency as it lls with retained grease. Thus, the Trapzilla stores large quantities
of grease without losing efciency. The unique compact design of the Trapzilla allows for installation into most
facilities. Options are available that enable a Trapzilla unit to be installed on the oor, suspended from the ceiling
or in-ground outside the facility.
Trapzilla units are designed to treat high ows of kitchen drainwater with large grease storage capacity
within a small footprint unit. These units are easy to maneuver into position and just as easy to plumb.
Grease interceptors, grease traps, automatic recovery units, grease removal devices and other similar
plumbing devices receiving kitchen ows from sinks, oor drains, woks and other food bearing sources
may generate odors. There are many factors inuencing odor evolution and dissemination. These include
room ventilation, kitchen menu, ambient temperatures, ware washing practices, grease/oil input, daily
input uid volume, sanitizers, installation plumbing design and product maintenance/upkeep. Odors are
usually prevented by good area ventilation, frequent uid inputs, good product maintenance practices
and proper product installation. Additional steps, including aeration, chlorination, pH control, improved
area ventilation and additional maintenance may be needed at some sites.

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 avail-
able 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.
Make sure the height above the Trapzilla access cover is enough to properly service the system.
3.1.2 Inlet/Outlet Piping
The inlet and outlet piping connections require exible sleeve pipe couplings. Keep outlet piping as
straight as possible. Thermaco, Inc. recommends installation of Two-Way Cleanouts on both the Inlet
and Outlet of Trapzilla Interceptors and Solids Separators in accordance with all applicable laws, regu-
lations and codes. These cleanouts should match the size of the Inlet and Outlet Piping (i.e. for
4” plumbing, a 4” cleanout should be used). Use only “sweep” connections. Do not reduce the pipe
sizing on the outlet piping. Do not install “P” trap on outlet connection of system. (Note: The system
already has a internal gas trap)
3.1.3 Flow Controls
Trapzilla systems are supplied with a Low-Head Flow Control module (LHFC). This should be connected
to the inlet of the Trapzilla unit in situations where ow rate needs to be restricted to the ASME rated
ow or when vented ow control is required by local code.
3.1.4 Venting the Outlet
An outlet vent or approved air admittance valve of at least 1/2 the diameter of the system’s outlet con-
nection must be present as close as possible to the Trapzilla outlet to prevent possible siphonage prob-
lems. The Vent on the Outlet piping is to be installed in accordance with all applicable laws, regulations
and codes. Failure to provide a vent for the system voids Thermaco’s Limited Warranty for the system.
3.1.5 For High Head Height Applications Over Six (6) Feet (1.95 m)
For installations where there is head height of greater than 6 feet (1.95 meters), Thermaco, Inc.
recommends installation of a code-approved Vented Flow Control Assembly (Thermaco VFCA not
included with Trapzilla).

Note: Drawing for reference only. Equipment must be installed in compliance with
all applicable laws, regulations and codes, including plumbing codes. Installation
should be performed by a qualied plumber.
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.

3.3 Plumbing Congurations
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. recommends installation of Two-Way Cleanouts on both the Inlet and Outlet
of Trapzilla® in accordance with all applicable laws, regulations and codes. These cleanouts should
match the size of the Inlet and Outlet Piping (i.e. for 4” plumbing, a 4” cleanout should be used).
A Vent on the Outlet piping is also to be installed in accordance with all applicable laws, regulations and
codes.

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. The ECA-TZ-29 may be trimmed
in the eld to t. Trim both the inner and outer portions of the extension collar to make shorter than
collapsed height. Thermaco, Inc. strongly recommends surrounding the in-ground Trapzilla with concrete
to provide additional structural strength and to offset buoyancy effects. For Buoyancy Calculations &
suggested concrete ll quantities please see page 22. Use the full TZ-600-ECA for 0-18” of collar needed
or purchase separately the TZ-600 and ECA-TZ-29 for 4-29” of collar needed.
In-Ground Installations inside of a building must have a vessel vent installed and piped to
atmosphere.
* Units using additional extension collars must use adapter lid and/or extension collars included
with unit.

5.2 Plumbing Instructions for Multiple Trapzilla Units Installed In-Ground
When installing multiple Trapzilla units in series, the change in elevation from the inlet to the outlet of a
unit requires each preceding unit to be installed 1” higher than the unit after it.
In-Ground Installations inside of a building must have a vessel vent installed and
piped to atmosphere.
* Units using additional extension collars must use adapter lid and/or extension collars included
with unit.
In-Ground Trapzilla Models ship with a
built-in, single-piece, 18” extension col-
lar that must be trimmed and then set to
the correct height to bring the Solid Top
Cover to grade.
Follow the steps below to set the exten-
sion collar prior to backlling the hole
with concrete.
Amount of extension collar needed to bring
Solid Top Cover to grade.
Step 2: Remove the extension collar adapter ring from
the unit with the extension collar still in place. On the
underside of the cover, mark the excess extension col-
lar length at the bottom of the four (4) “skirt” portions
of the adapter ring. Check the extension collar height
dimension frequently during this marking to ensure that
the collar has not moved. Extend this mark between the
gaps in the “skirt” so that the collar is marked all around.
Step 1: With the Trapzilla unit installed in its perma-
nent location, raise the telescoping extension collar to
nished grade or oor level. Measure the height from
the top of the unit to this nished extension collar height
and record this dimension.
Note: If the oor will have a tile covering alow for the tile
thickness when determining the extension collar height.

Step 5: Working from the bottom of the assembly, in-
stall eight (8) self-drilling, self-tapping screws (provided)
through the extension collar wall and into the adapter
ring. Two of these screws should be installed in each
of the four (4) skirt areas of the adapter ring. Check
the extension collar height dimension frequently during
this operation to ensure that the collar has not moved.
Note: Use caution when tightening these screws to en-
sure that they do not strip.
Step 6: Place the adapter ring/extension collar assem-
bly onto the Trapzilla unit. Position the small cover onto
the extension collar. Secure the adapter ring and the
small cover with the brass nuts and at washers provid-
ed. Seal the gap between the 18” extension collar and
extension collar adapter ring using a silicone sealant.
Step 3: Remove the extension collar from the adapter
ring and, with an appropriate saw, cut along the line cre-
ated in Step 2 to remove the excessive extension collar.
Step 4: Reinsert the extension collar into the adapter
ring ensuring that the cover alignment key on the ex-
tension collar is aligned with its recess in the adapter
ring. Reset the extension collar height to the dimension
determined in Step 1.

5.4 Concrete Calculations for TZ Models/Components
In order to offset the effects of buoyancy caused by groundwater (high water tables), strengthen the
sideload of the unit, and prevent movement of the unit in the event of shifting earth, Thermaco, Inc.
recommends concrete be poured around the entirety of Trapzilla® units installed in-ground in the amounts
of concrete specied in the table below. The concrete must to be poured continuously and completely
surrounding the Trapzilla® body (and Extension Collars if applicable) to ensure proper strength and
security at a compression strength of 4000 psi (C28/35).

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 efciency. 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. Note the size of the unit which is marked
on the cover by a metal plate.
2. Place a grease/sludge dipstick into the center of the Trapzilla, making sure that it goes through
the hole in the horizontal bafe.
3. Once the dipstick has found its natural resting place at the lowest point in the conical shaped
bottom, take the measurement.
4. Remove dipstick and compare grease/sludge levels to the corresponding unit in the charts below.

Periodically, the Trapzilla® unit will need to be serviced which
involves pumping out the accumulated grease & solids. Each
lid has four brass nuts securing the lid. Fully remove the lid to
access the grease. Begin by taking the grease from the top of the
main chamber. Upon reaching the horizontal bafe, you will see
a hole through which you may access the rest of the grease and
the solids. Be sure to lower the hose all the way to the bottom
of the Trapzilla unit so that solids may be entirely removed.
Note:
1. DO NOT use mechanical crust breaking devices to break down any mat that has formed inside
the Trapzilla unit.
2. Remove the four brass nuts from the bolts and fully remove the lid to pump out.
3. It is not necessary to remove adapter lid (ring) to pump out Trapzilla.
4. If necessary, use a water hose with spray nozzle to rinse off inside of unit.
5. DO NOT use grinding augers in maintenance of the Trapzilla unit.
Begin by pumping grease from upper
chamber, until you can see the entire
horizontal bafe.
May be necessary to use water hose to
rinse out parts of upper chamber.
Drop hose into lower chamber through hole
in horizontal bafe, pumping out all liquids
and solids remaining.
Again, it may be necessary to use water
hose to rinse out lower chamber.
