Antifoam cartridge preparation
To optimize the performance and reliability of the instrument, it is strongly recommended to only use
the silicone antifoam supplied by Hach Lange (part number 33156). To fill the cartridge, refer to the
steps that follow and Figure
1. Lower the piercing assembly (refer to
the antifoam cartridge connector. Raise the transparent front door.
2. Push the refill bottle onto the antifoam cartridge connector until the bottle clicks into place.
3. Squeeze the refill bottle to force as much antifoam as possible out of the bottle and into the
antifoam cartridge.
4. Maintain pressure on the bottle to avoid any antifoam being sucked back into the bottle. Press on
the lock on the top of the bottle to release it from the antifoam cartridge, and pull the bottle down
to remove it.

Note: After installation of the antifoam, it is critical that any air bubbles be cleared from the antifoam circuit
before taking any measurements. To do this, select the Antifoam system option from the Actuator
verification option in the Maintenance menu and follow the instructions as described in
on page 22. Select 200 injections and stop the process when the system constantly spits a small stream of
antifoam at each stroke denoting the antifoam circuit is free of air bubbles.
Note: A cartridge completely filled with antifoam is sufficient for approximately 3,000 measurements.
