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 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.
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.

5.4 Concrete Calculations for Solids Separators Models
In order to offset the effects of buoyancy caused by groundwater (high water tables), Ther-
maco, Inc. recommends concrete be poured around the anchor ring and the Trapzilla
®
units
installed in-ground. The amount of concrete to be used is specied in the table below. The
concrete is to be poured continuously and completely surrounding the Trapzilla
®
Solids
Separator (and Extension Collars if applicable) to ensure proper strength and security.
Buoyancy Calculations TSS Models/Components
Amount of Concrete
TSS Model Weight (lbs.) Volume (Cu. Yards)
TSS-95-ECA 1975 0.50
TSS-70-ECA 1525 0.40

fully extended and 29” Two-Piece
Extension Collar fully extended for a
total of 47” of additional depth for unit.
Concrete should fully encircle the unit
up to the surface. A small amount of
space (up to 4”) may be left unlled to
cover with dirt and grass if installed
outside.
