IDC2 EVAPORATIVE CONDENSERS
INSTALLATION
140.940-IOM (DEC 13)
Page 6
Refer to the certified unit print for the proper orientation of
each cell. The cell number and “face” are stenciled on the outer
basin wall. Multi-cell unit installations may use flume boxes to
equalize the water level in the basin of each cell.
Follow directions below for details on their installation:
•
First, attach the first cell’s lower section to the support and
then fasten the first cell’s upper section to the first cell’s
secured bottom section.
•
Each subsequent cell should be assembled just adjacent to
its final location, and then properly positioned next to the
previous cell.
•
Use the flume box installation procedure to connect the
basins of multi-cell units.
IDC2 FLUME BOx INSTALLATION
NOTICE
Flume boxes furnished with units constructed with stainless
steel basins and the TripleGuard™ Corrosion Protection
System are assembled with stainless steel bolts, washers
and nuts in lieu of self-tapping screws.
NOTICE
For units equipped with the positive closure plate option,
skip last step on this page and go to the positive closure
plate section of this manual.
•
Position Cell #1 on the unit support and bolt in place.
•
Wipe down the mating surface by the flume opening to re-
move any dirt or moisture that may have accumulated during
shipment.
•
Wipe down the flanges on both ends of the flume box. On
one end, apply a layer of 1/8” x 1” butyl sealer tape around
the face of the flange over the centerline of the holes. Do
not overlap or stretch too thinly at the corners. When it is
necessary to splice the sealer, 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.
•
Using drift pins to align the bolt holes, place the flume box
over the opening in the basin of Cell #1 and fasten into place.
Insert the 3/8” self-tapping screws or bolts from the flume
box into the basin wall as illustrated in
Figure 6
.
•
Apply sealer to the other end of the flume box as described
in bullet 3 above.
•
Position Cell #2 on the unit supports. Wipe down the mating
surface by the flume opening to remove any dirt or moisture.
•
Using drift pins to ensure alignment, draw Cell #2 tight against
the flume box.
•
As illustrated in
Figure 6
, insert 3/8” self-tapping screws in
each hole from the flume box into the basin wall and tighten.
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 IDC2 Evaporative Con-
densers, the plate ships loose inside the basin. To install the
Positive Closure Plate and gasket, follow the “Positive Closure
Plate Installation” then complete the installation of your specific
type of unit using the instructions listed.
Positive Closure Plate Installation (Figures 7, 7a & 7b)
•
Thread 3/8” self-tapping screws from the flume box into the
basin wall with the positive closure plate as shown.
•
Position the neoprene gasket and positive closure plate over the
bolts and fasten in place with 3/8” wing nut and flat washers.
