Maintenance and Troubleshooting
21. 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, and make sure that the O-ring remains
in place on top of the cartridge. 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.
22. 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.
23. Gently screw the sensor clockwise into the replacement cartridge, applying minimum
pressure to avoid any damage to the screw threads.
24. 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
25. 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.
