YSI 9600 - Manual (Page 21)

Locate the two black straps in one of the carousel segments that will be used to retain the cadmium column
assembly. Note that there is a section of tubing within the straps with two ends with brown threaded
fittings that are connected by a translucent nut.
NOTE: For optimum performance, the cadmium column should be installed in the flow system of the
carousel so that the direction of flow through the column is the SAME as that used in its activation.
To make sure that the direction of flow through the cadmium column is correct, note that one of the
sections of tubing within the carousel straps tubing goes to a circular tan fitting with two other pieces of
tubing connected to it. This fitting on this section should be attached to the OUTLET of the cadmium
column as marked during the activation process. See the picture below left to identify the tubing nut that
goes to the cadmium tube outlet.
Outlet
Circular Fitting
Loosen the straps by pushing up on the tab and pulling on the strap as shown in the picture above right.
Remove the translucent coupling nut so that the two threaded brown fittings are free. As noted above,
identify the threaded nut that goes to the circular tan adapter. Remember that this nut should be attached to
the OUTLET of the cadmium column assembly.
Screw the threaded fittings on the tubing ends into the ends of the cadmium column assembly after
removing the plugs from the column. Use only finger tightening to make the connection – no tools should
be used.
CAUTION: Be certain to retain the two black plugs that were removed from the cadmium
column prior to its installation. These plugs will be required to seal the column assembly
for proper disposal after its reducing capacity has been expended.
Align the connected cadmium column assembly vertically within the strap clamps and pull the end of the
straps so that the column assembly is held in place firmly as shown in the picture below. Note that the
straps should fit within the indentations on the cadmium column assembly.
