Circulation pump
The circulation pump is a pre-assembled unit.
Installation consists of bolting it in the mounting flange
with gaskets and tightening the bolts on the discharge
manifold and pump flange. The pump contains a
mechanical seal which in some installations may
require the connection of a cooling water inlet and
drain.
Install the pump wiring and check:
1.The voltage rating on the motor against the supply
voltage.
2.The rotation of the pump motor. The proper direction
is marked on the motor mount. If the motor rotates
backwards, reverse any two wires.
Electrode Installation
Assemble high voltage cage. Electrode installation includes installing the electrode lead-through and
the electrode housing, positioning the electrode housing, and positioning the counter electrode. The
electrode housing must be installed squarely and at equal distances from the nozzles, and so that the
water streams discharged from the nozzles strike the center of the electrode target plate.
Install the electrode rod assembly through the electrode nozzle in the vessel with connected electrode
box and target plates. Adjust connection bolts until the electrode plates are positioned at an equal
distance from the nozzle stock. After ensuring the electrode boxes are properly positioned, tighten the
electrode rod nuts to 500 ft lb of torque. This will compress the spring washer to almost fully flat.
Hydraulic system
Install hydraulic lift tower assembly and hydraulic cylinder. Connect hydraulic cylinder to control rod
using the supplied adapter sleeve (see Figures 9 & 10).
