Fiberglass Cooling Towers 

Chapter 3: Installation 

Page 12 of 25 

 

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.
