1. Hold the main body of the sensor and unscrew the protection cap locking washer by turning
counter-clockwise. Remove it from the sensor and put to one side.
2. Pull/twist off the protection cap and put to one side. Remove the Dacron
cap and discard it.
3. Hold the sensor with the membrane facing down to avoid spilling any electrolyte, then carefully
unscrew the old cartridge. Drain the old electrolyte into a sink and flush away. Discard the old
cartridge and membrane. If present, remove the cotton washer from the top of the anode and
discard.
4. Rinse the sensor head under a tap for 15 seconds to remove any remaining electrolyte and shake
dry. With a soft tissue gently clean around the guard area (indicated above) and then wipe off any
excess moisture from the sensor to ensure all parts are completely dry. Repeat this rinse and dry
process with the protection cap.

5. With the help of a pair of tweezers, remove the old O-ring from the sensor body. Replace the O-
ring with a new one from the recharge kit.
6. Clean the anode using the cleaning tool supplied. Place the tool over the sensor head. Clean by
rotating the cleaning tool over the sensor head for a few seconds, in a clockwise direction only.
7. Remove the tool and tap it face down on a flat work surface to remove any powdery deposit.
Check the sensor to ensure that all deposits have been removed from the anode. If not, repeat
step 6. until the anode regains its bright silver appearance.
8. Rinse the sensor head under a tap for 15 seconds, aiming the jet of water directly onto the sensor
head. Do not dry the center electrode area, as the gap between cathode and guard should be left
filled with water.
