Joining Multi-Cell Units
Basin Sections - 17’ and 24’ Wide Models (12’ to 40’ Long)
4. Clean the mating flanges on the equalizer flume on the
end to be field connected. Apply a layer of sealer tape on
the flange, centered between the hole centers and the
outside edge. Remove paper backing strip from the sealer
tape.
5. Clean the mating surface of the side panel of any dirt,
grease or moisture. Rig the second basin section adjacent
to the equalizer flume on the steel support.
6. Align the bolt holes in the equalizer flume and equalizer
opening with drift pins while drawing the second basin
section against the first as shown in Figure 8.
7. Install 3/8” bolts, nuts and washers in every hole around
the equalizer opening and tighten. Cut off excess sealer
tape to prevent strainer blockage
8.
Bolt the second basin section to the steel support.
9. Place the drip channel over the adjoining pan section
flanges. Secure by installing 5/16” self-tapping screws
through the retaining clips into the side panel. For
stainless steel construction, secure by installing ¼”
stainless steel bolts through the retaining clips into brass
rivnuts secured in the side panel. (See figures 8 & 9.)
10. Fasten the drip channel sections together, end to end, by
driving a self-tapping 5/16” screw through the section end
with the larger hole into the mating end with the smaller
hole. Stainless steel units will use 5/16” stainless steel
nuts, bolts, and washers. (See Figure 9.)
11. Place the vertical splash guard in the bend of the vertical
supports. Attach the vertical splash guard using 5/16”
tappers. For stainless steel constuction, attach the vertical
splash guard using 5/16” stainless steel nuts and bolts.
(See Figure 10.)

Applying Sealer Tape
Once the bottom section has been set on the supporting steel
and bolted in place, the top flanges should be wiped down to
remove any dirt or moisture. Sealer tape should be placed over
the mounting hole centerline on the side flanges. Apply two
strips of sealer tape, one partially overlapping the other, on the
end flanges.
The sealer tape should overlap on the corners as shown in
Figure 11. Do not splice the sealer tape along the end flanges
and preferably not on the side flanges if it can be avoided.
Always remove the paper backing from the sealer tape.
Units that are 24’ to 40’ in length have two or more coil/fan
sections. In these cases, sealer must be applied to all internal
flanges. Cut off excess sealer tape once the top section has
been properly set into place and the rig is complete.
