Positive Closure Plate Option

The optional Positive Closure Plate and gasket can be furnished on
multi-cell units to allow individual cells to be isolated for cleaning
and routine maintenance.  For PT2 Cooling Towers, the plate ships
loose inside the basin.  To install the Positive Closure Plate and 
gasket, follow the steps that correspond to your unit from the 
“Assembly of Multi-Cell Towers” section; then complete the 
installation of your specific type of unit using the instructions listed. 

Positive Closure Plate Installation (Figures 9 and 10):

1.  Thread 3/8” self-tapping screws from the flume box into 

the  basin wall with the positive closure plate as shown 

2.  Position the neoprene gasket and positive closure plate 

over the bolts and fasten in place  with 3/8” wing nut 
and flat washers

Water Baffles

For multi-cell PT2 Cooling Towers, water baffles join the air louver sections to prevent leaks.  To 
install the water baffles, follow the steps below.

Water Baffle Installation (Figure 11):

1.  Slide lower water baffle into place  

2.  Install left and right side water baffles by first aligning top notches and then sliding bottom 

into place.  Install 3/8” self-tapping screws in each hole provided
