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 1a and 1b. 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 2 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.

Joining Multi-Cell Units
On all 2-cell models, the two bottom sections are shipped
separately and are typically furnished with a connecting equalizer
flume box between them.
In addition to the equalizer flumes, these units are provided with
horizontal drip channels and vertical splash guards to keep water
from splashing out from between the cells. All units have one or
more horizontal drip channel and two vertical splash guards per
flume box. Flume boxes are a standard offering on multi-cell units.
The equalizer flume box 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 procedures that follow should be
performed in sequence.
