Resin replacement
Note: In order to take advantage of the full system specifications, we recommend the use of nuclear grade cationic
resin.
For this operation, you can either replace the existing cartridge of resin with a new one (part number
09523=A=7000) following the instructions in
on page 12, or keep
the cartridge and refill using the resin replacement kit (part number 09523=A=7010) and following the
instructions in
on page 13.
Cartridge replacement process
1. Stop the sample flow using the sample flow adjustment valve (A).
2. Unscrew the used cartridge from the measuring cell and remove carefully by pulling down on the
cartridge until it clears the steel tube (B). The steel tube must remain in place.
3. Discard the used resin following the safety and disposal information for both the used resin and
used cartridges.
4. Take the new resin cartridge and turn it upside down 2 or 3 times until the resin comes away from
the sides of the cartridge and settles at the bottom, at the opposite end to the marker line.
5. Unscrew the cap off the top of the new cartridge, by the marker line. Discard this cap and the flat
black sealing cap following the safety and disposal information for used cartridges.
6. Place the end of the steel tube into the center of the cartridge (C).
