shipment cartridge and membrane. Remove the cotton washer and silicone disc 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.

Note: During this 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 silicone disc from the recharge kit, hold it between thumb and forefinger and position it on
top of the anode. Take a new cotton washer from the recharge kit. Hold it between thumb and
forefinger and position it on top of the silicone disc.
6. 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, 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.
7. 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.
8. Gently screw the sensor clockwise into the replacement cartridge, applying minimum pressure to
avoid any damage to the screw threads.
