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.

5. Place the recharge cartridge container on a flat work surface and, keeping the container upright
to avoid spilling any of the electrolyte inside, carefully unscrew the top. Remove the packing
component from the center of the cartridge, making sure that the O-ring on top of the cartridge
remains in place. If it comes away then replace it before continuing. If there are any visible
bubbles in the electrolyte, remove them using a stirring motion with the packing component.
6. Hold the container steady between thumb and forefinger of one hand. Lower the sensor into the
container until the top of the anode is covered with electrolyte.
7. Gently screw the sensor clockwise into the replacement cartridge, applying minimum pressure to
avoid any damage to the screw threads.
8. Continue turning until the cartridge is attached to the sensor, and the sensor is automatically
released from the container. The empty container, the screw top and packing component can be
discarded.
Note: It is normal that some of the electrolyte will overflow from the replacement cartridge and into the plastic
container.

9. Rinse the sensor under a tap for about 5 seconds to remove any excess electrolyte, then gently
wipe with a soft tissue to ensure all parts are completely dry. Drain the overflow electrolyte from
the container into a sink and flush away. Discard the used container.
