Positive Closure Plate Installation
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. The plate ships loose
inside the cold water basin.
1. Remove nuts and flat washer from the flume box.
2. Position the neoprene gasket and positive closure plate over the bolts and fasten in
place with 3/8” wing nut and flat washers.
3. When the cooling tower operation does not require use of the positive closure plate,
remove the closure plate and gasket. Retighten the flume box using the wing nuts and
flat washers.
