Section Assembly
Note: IBC Rating is void if section assembly is not performed as described below.
Two-section PT2 Cooling Tower assembly:
Position the lower section in the working location. No sealer tape is required on the InterLok™
Casing joint. Using drift pins in the bolt holes provided, guide the upper section onto the lower
section. Match marks must line up. Bolt in place as illustrated in Figure 5, using a 1/2” bolt and flat
washer. The assembled PT2 Cooling Tower is now ready to be lifted onto the tower support as a
single piece and bolted into place. Use the lifting devices provided at the top of each unit as shown in
Figure 2.
Three-section PT2 Cooling Tower assembly:
To assemble a three-section unit, position the lower section on the tower support and bolt in place.
No sealer tape is required on the middle InterLok™ Casing joint. Using drift pins in the bolt holes
provided, guide the middle section onto the lower section. Match marks must line up. Bolt middle
section in place as illustrated in Figure 5, using a 1/2” bolt and flat washer. Remove disposable
middle section lifting ears and discard. Next, wipe down the mating surface of the top section to
remove any dirt or moisture that may have accumulated during shipment. On one end, apply a layer
of 1/8” x 1” foam tape around the face of the flange over the centerline of the holes. As illustrated in
Figure 4, insert 3/8” self-tapping screws in each hole from the upper section into the middle section
and tighten.
Note: On quad installations, it is suggested that cells subsequent to the first have the upper and lower sections assem-
bled on the support foundation adjacent to the final mounting locations. This will allow space for securing the upper and
lower sections of each cell. Slide the subsequent cell(s) to their final position using the lifting devices at the top of the
cell(s). Refer to the “Assembly of Multiple-Cell Units” section for details. All multi-cell units have the cell number and
“face” identified on each section as well as match marks to show how the cells are to be mated.
Assembly of Multi-Cell Towers
Refer to the unit certified print for the proper orientation of each cell. The cell number and “face” are
stenciled on the outer basin wall. Multi-cell cooling tower installations may employ flume boxes to
equalize the water level in the basin of each cell. Follow directions below for details on their
installation. First, attach the first cell’s lower section to the foundation and then fasten the first cell’s
upper section to the first cell’s secured bottom section. Each subsequent cell should be
assembled just adjacent to its final location, and then properly positioned next to the previous cell.
