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 shipment cartridge. Drain the old electrolyte into a sink and flush away. Discard the
shipment 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, 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.
