ATC-E, ATC-ES, ATWB, eco-ATWB and eco-ATWB-E Evaporative Condensers and Closed Circuit Coolers
Equalizer Blank-Off Plate:
Multi Cell Units
Equalizer blank-off plate(s) are available to isolate the
bottom sections for individual cell operation, periodic
cleaning, or maintenance.The optional equalizer blank-off
plate is factory installed on the equalizer flume and
secured by wing nuts. This plate is also known as a
"flume plate" or "positive closure plate."
For units not requiring the blank-off plate under normal
operating conditions, remove the wing nuts, washers,
plate and gasket. Reinstall washers and wing nuts for
proper leak free operation of the equalizer flume box.

Application of Sealer Tape

Once the bottom section has been set on the supporting steel and bolted in place, the top flanges should be wiped down to remove
any dirt or moisture. Sealer tape should be placed over the mounting hole centerline on the side flanges along the entire length of
all sides. Apply two strips of sealer tape, one partially overlapping the other, on the entire length of the en flanges (flanges with no
bolt holes).
The sealer tape should overlap on the corners as shown in Figure 5a. Do not splice the sealer tape along the end flanges and
preferably not on the side flanges if it can be avoided.
Always remove the paper backing from the sealer tape.
All models with two or more top sections must have sealer tape applied along the entire length of all internal flanges, as shown in
Figure 5b.
