21. Note: As in the previous step, it is very important to ensure your finger does not come into contact with the
cathode (golden surface) as it could leave greasy deposits on the surface.
Take a new cotton washer from the recharge kit. Hold it between thumb and forefinger and
position it on top of the silicone disc.
22. Note: The recharge cartridge container will be colored black for all applications except for the 6110 TPA where
it will be colored white.
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.
23. 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. Leave for a few seconds to ensure
the cotton washer has fully absorbed some of the electrolyte and that it is no longer dry.
24. Gently screw the sensor clockwise into the replacement cartridge, applying minimum pressure to
avoid any damage to the screw threads.

25. 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.
26. 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.
