b. Using the working electrode block, spread the paste evenly over the
pad. Then, applying firm pressure in a figure eight motion, polish the
surface of the electrode block for about one minute. If the pad dries
out while polishing, add water sparingly. However, never allow the
polishing compound to dry on the electrode.
c. Use ASTM Type I (18 megohm-cm) filtered and deionized water that
meets the specifications listed in
polishing compound from the electrode block. An ultrasonic cleaner
is effective for thoroughly cleaning the electrode block. Carefully
rinse the surface of the block with ASTM Type I (18 megohm-cm)
filtered and deionized water.
4. If you used the coarse polishing compound in
the fine compound.
5. Using a moist piece of polishing cloth (with no polishing compound
added), rub the polished surface free of residual polishing compound
particles.
6. Inspect the surface of the working electrode to make sure that it is clean.

7. Replace the working electrode block and yoke knob. Fingertighten the
knob by turning it a full 360 degrees.
NOTE
8. Orient the cell assembly with the yoke knob on the left and push the cell
onto its mounting location in the DC compartment.
9. Reconnect the cell's inlet and outlet lines.
10. Reconnect the electrical cables.
11. Start the pump flow.

Step 5, if necessary.
The polishing pads are reusable. Do not rinse the pol-
ishing compound from the pads. After initial use, add
only enough polishing compound to maintain the coat-
ing on the pad.
It is not possible to overtighten the yoke knob. Once
the knob clicks into place, it does not tighten any fur-
ther. The yoke knob ensures constant pressure is
applied to the cell.
