Rigging Basin Section
Lifting devices are located in the upper corners of the basin
section for lifting and final positioning purposes as shown in
Figures 3 and 4. The hook of the crane must be a minimum
dimension of “H” above the top of the section being lifted to
prevent undue strain on the lifting devices. See Table 1 for the
minimum “H” dimension. These lifting devices should not be
used for extended lifts or where any hazard exists unless
safety slings are employed under the section. (See “Extended
Lifts” section for proper arrangement.) Bolt the basin section to
the steel support before rigging the coil/fan section.

The bottom sections are shipped separately and are furnished with a connecting equalizer flume between them. In addition to the
equalizer flumes, these units are provided with drip channels and splash guards to keep water from exiting between the cells.
The equalizer flume is factory installed on one section for field
connection to the other. It is important to connect the equalizer
flume to balance the water level in the pans for proper pump
suction operation. The following procedures are to be
performed in sequence.
1. Install the basin section with the factory installed flume on
it as described earlier.
2. Clean the 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. (See
Figure 5.)
3. Clean the mating surface of the equalizer opening of any
dirt, grease or moisture.
