Make sure to remove the label before the sensor is deployed or pressurized or the conductivity cell can be
damaged.
1. Remove the yellow label.
• The user can make sure the anti-fouling devices are installed: refer to "Remove or replace anti-
fouling devices" for details.
2. Keep the label to attach again to protect the intake and exhaust ports when the sensor is not
deployed.
5.2 Remove or replace anti-fouling devices
Remove the anti-fouling devices as a first maintenance task to save the anti-fouling material for
deployments.
1. Use a 5/32 inch hex wrench to loosen the two captured cap screws that attach the copper anti-
fouling assembly to the plastic assembly on the pressure housing. Carefully remove the copper
anti-fouling assembly from the housing.
2. Remove the three Phillips-head screws from the copper anti-fouling assembly, and pull the
copper guard off of the plastic anti-fouling holder.
3. Remove the protective plug from the anti-fouling device cup.
4. Use a toothpick to lift each of the anti-fouling devices out of the holder. If necessary, use needle-
nose pliers to carefully break up the device.

Procedure
Insert new anti-fouling devices into the cup, then install the cap onto the cup. Do not
tighten too tight.
Attach the copper assembly to the sensor again.
Do not insert new anti-fouling devices. Install the protective plug. Make sure to remove
the plug before the next deployment or pressurization of the sensor. Damage to the
conductivity cells can be caused if the plugs are not removed.
