Side Outlet Depressed Sump Box (Optional)
The optional side outlet depressed sump box allows a cooling tower water outlet
connection to be piped from underneath the unit in four possible directions, 90° apart.
The piping connection is a bolt circle designed to fit an ASME Class 150 flat flange with a
full-face gasket. To install the side outlet depressed sump box, follow the steps below.
1. Wipe the edges around the opening inside the cold water basin to remove any dirt or
moisture that may have accumulated during shipment.
2. Apply a layer of 1/8” x 1” butyl sealer tape around the opening in the basin over
the centerline of the holes. Do not stretch the sealer tape too thinly or overlap at the
corners. When it is necessary to splice the sealer tape, be sure to press the two ends
together to form a smooth continuous strip. Apply a second layer of sealer tape over
the first layer following the same procedure. Refer to
Figure 17
. The sealer tape needs
to be positioned between the sump box and the inside basin bottom.
3. Insert the sump box assembly into the opening in the cold water basin and attach it
to the basin with 3/8” x 1” bolt and nuts, flat washers, and lock washers as shown in
Figure 17, Detail A
.
4. Place the suction strainer over the opening as shown in
Figure 17
.
