1. System Overview
The Thermaco, Inc. Trapzilla®Supercapacity
Grease Interceptor collects free-floating
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 at 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.
Hydromechanical grease interceptors, 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.
*Devices formerly referred to as grease traps are now called hydromechanical grease interceptors.

3. 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. 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, regulations
and codes. These cleanouts should match the size of the Inlet and Outlet Piping (i.e. for 4” Inlet/
Outlet piping, 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
connection must be present as close as possible to the Trapzilla outlet to prevent possible siphonage
problems. 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 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 in-door 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 plug and connect appropriate vent lines as indicated below (for 2” vent
connection, use 2” pipe).

3.3 Plumbing Congurations
3.3.1 One TZ-1826
Each Trapzilla unit is shipped with a Low Head Flow Control module (see LHFC box for additional
instructions). When applicable, 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.

4.3.2 Construction of Riser for TSS-95-SSA installation in series with TZ-1826-SSA
For the installation of a TSS-95-SSA prior to the TZ-1826-SSA, a riser must be constructed to raise the
smaller unit by 8” and provide full support for the weight of the interceptor and its contents.
4.3.3 Installing Multiple TZ-1826-SSA 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 1.5” 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.
All installations inside of a building must have a vessel vent installed and be piped to atmosphere.

4.3.4 Installation of Pipe Hangers with Above-Ground Units
Trapzilla units installed indoors, above-ground require the use of pipe hangers (purchased separately)
to properly support plumbing and reduce stress on connections with unit. Thermaco recommends the
use of four (4) Zinc-plated Steel Loop Style hangers with 1000 lbs. work load limit for a single Trapzilla
installation with two (2) hangers placed before inlet side cleanout and two (2) hangers placed after nal
cleanout.
Place each pair of hangers 35” apart (space-permitting) and no closer than 5” from any joint. When
multiple units are installed place one (1) additional pipe hanger in between each unit, leaving 5” distance
from unit and cleanout. Follow pipe hanger manufacturer’s instructions for physical installation.
5. In-Ground Installation Instructions
5.1 Plumbing Instructions for Single TZ-1826 Installed In-Ground
A Trapzilla unit may also be installed in the ground inside or outside of the facility. For instances
where the facility drainage piping requires an extension collar that is more than the 18” provided
by the built-in extension, the ECA-TZ-29 Extension Collar Assembly may be installed to align the
Trapzilla inlet with the drainage piping. 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 fill quantities please see page 17.
In-Ground Installations inside of a building must have a vessel vent installed and be piped to
atmosphere.
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.

5.3 Concrete Specications for In-Ground Installation
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).

5.2 Plumbing Instructions for TZ-1826 with Optional ECA-TZ-29 Extension Collars (purchased
separately)
In some cases, TZ-1826 may be installed in locations where built-in extension collar will not reach grade.
In these cases, the two-piece ECA-TZ-29 Extension Collar (purchased separately) may be used to make
lid accessible at ground level. Follow instructions included in ECA-TZ-29 packaging for installations.
Each TZ-1826 would require two (2) ECA-TZ-29 if pipe depth requires.
* In-ground installation instructions only applicable for units installed where center of outlet pipe is
no more than 60” below grade. For all installations deeper than this, Thermaco must be contacted
to verify site conditions and provide further instructions for proper installation. Failure to abide by
this instruction will result in voiding the warranty of the unit.
In-Ground Installations inside of a building must have a vessel vent installed and piped to at-
mosphere.
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.

5.5 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.
Follow the steps below to set the extension
collar prior to backfilling 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 collar 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 permanent
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, allow for the tile
thickness when determining the extension collar height.

Step 5: Working from the bottom of the assembly, install
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 ensure that they do not strip.
Step 6: Place the adapter ring/extension collar assembly
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 provided. 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 created 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 extension
collar is aligned with its recess in the adapter ring.
Reset the extension collar height to the dimension
determined in Step 1.

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.
IMPORTANT: Excess extension collar must be trimmed on all units. Do not allow
additional extension collar to extend beyond bottom of adapter ring. On units
where extension collar is completely recessed, the extension collar should still
be secured and the excess extension removed as in step 3.

6. Unit Maintenance
6.1 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 22” Solid Top Cover.
2. Place a grease/sludge dipstick into the center of the opening, 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.

TZ-1826 25” 20” 13.5” 10.75”
Take solids/sludge measurement from
bottom of unit upward and compare to
chart above.
Take grease measurement from top of
liquid level downward and compare to
chart above.
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.
6.2 Pumping/Servicing Unit
Periodically, the Trapzilla® unit will need to be serviced which involves pumping out all accumulated
grease and solids. Pumping frequency may be set at a regular interval by sewer district (every 30-90
days). If not, determine pumping frequency using instructions in 6.1 to periodically measure grease/
solids levels to determine appropriate timing for pumping. Follow instructions below to pump/clean out
TZ-1826.
1. Each lid has four brass nuts securing the lid. Remove the four brass nuts from the bolts and fully
remove the 22” lid to pump out. It is not necessary to remove adapter lid to pump out Trapzilla.
2. Begin by taking the grease from the top of the main chamber until all grease is removed.
3. 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
on the outlet side so that solids may be entirely removed. The conical shape and natural grade of
the unit will allow solids and grease to run to outlet side of unit.
4. Have kitchen run water into unit to ush any remaining solids to the outlet end of the unit.
5. If necessary, use a water hose with spray nozzle to rinse off inside of unit.
6. Secure lids in place and instruct kitchen to run water into unit until full.
DO NOT use mechanical crust breaking devices to break down any mat that has formed inside the
Trapzilla unit.
DO NOT use grinding augers in maintenance of the Trapzilla unit.
