Fiberglass Cooling Towers Chapter 3: Installation Page 12 of 25
3-2 Assembling the Cooling Tower in the Field
Your cooling tower may have been shipped on two skids to reduce shipping charges.
One skid contains the lower section, identified by the black fill wrapped in plastic on the
inside of the lower section. The second skid contains the top tower section bolted over the
fan/motor assembly. Perform the following procedure to properly assemble the two sections
if the sections shipped separately.
1. Remove the clear plastic protective wrapping from the fill.
2. Inspect both sections for any damage, and locate the red orientation mark on one of
the vertical sides of each section.
3. The manufacturer supplies self-adhesive gasketing material to insure a water-tight
seal between the top and bottom sections. Install this material on the top of the
attachment flange on the lower section prior to mating the top and bottom sections.
Make sure that the flange is clean, dry, and free of rough spots before applying the
gasketing material.
4. Align the holes in the gasket with the bolt holes in the flange, then remove the paper
on the back side. Cut the gasketing material to fit properly, and apply the gasket to
the flange as you realign gasket holes with flange holes. Repeat on all four sides of
the tower.
5. Apply silicone caulk in cut lines and voids to complete sealing between sections.
6. Unbolt the top section from the skid and make sure that the flange on the top section
is clean, dry, and free of rough spots.
7. Place the upper section on the gasketed lower section, aligning the red orientation
marks. Take care not to disturb the gasketing and silicone caulk while aligning bolt
holes.
8. After aligning, bolt the two sections together with the fasteners provided. Use a flat
washer under the bolt head on top and a flat washer, a lock washer, and nut on the
bottom side of the flange.
