Think and act in a safe manner. Always disconnect power and use a lockout before you work on the E-coat system, or any of the related subsystems. Observe any confined space conditions. Use the appropriate safety equipment and clothing for the task. Please carefully read all the instructions listed below to familiarize yourself with the project before attempting to perform any of the work.

Required Materials

  • Electrode Holder (call UFS) or old Membrane Shell
  • D.I. Water
  • 5 minute epoxy or PVC shrink wrap

    Required Tools

  • Crescent wrench, Pliers, Matt knife
  • Saw Horses


    Occasionally, a flushable Cell may need to be changed to a bare Electrode. Since the Electrodes in TECTRON™ Cells are usable without the Membrane Shells, TECTRON Cells can easily be converted from flushable to bare Electrodes. The Membrane Shells can be stored and re-used at a later time if desired.

    1. Turn off the power to the system and lock out the DC rectifier with your own lock. Disconnect the Cell Cable Lead quick connect.
    2. Turn off ¼” supply valve and remove the supply tubing from the top of the flow indicator. Remove the Return tubing from the Overflow Nozzle and the Return Manifold. Pull the Anode from the E-coat tank.
    3. After the Anode has been removed, rinse off using a D.I. hose. Place the Anode on the sawhorses. Working at the bottom of the Anode, pull out the PVC C-ring with pliers. Grasp the black boot with pliers and pull the boot and the supply tubing out of the Anode. If unable to reach the black boot, insert a small diameter pipe in the top of the Anode and push the supply tubing and boot out. Save these parts for future needs. Brush on a thin layer of two-part epoxy on the portion of the Anode pipe where the tab was welded to insulate, or use PVC shrink-wrap to cover the portion of the Anode that was heated up during the welding of the Anode Tab.
    4. Remove the Membrane Shell from the Tank. Refer to Bulletin 990134 for long-term storage instructions, if you have purchased a new Anode Holder, skip to the next step. If you want to convert an old Membrane Shell into an Anode Holder, remove the Membrane Guard, if necessary. Use a sharp matt knife to cut away the outer wrap and membrane with a series of two circumferential cuts at the cap and collar and a longitudinal cut down the length of the membrane. Do not cut through the inner support tube. Finally drill a 12.7 (1/2”) hole in the bottom center of the PVC cap to allow ED paint to drain.
    5. Place the Anode Holder (or modified Shell) in the same location as before and secure with two clamps.
    6. Place the Anode into the holder in the tank.
    7. Reconnect the Electrical Cable Lead.
