Changing the Cassette Seal
The cassette seal will last approximately 500 to 800 cycles. There should never be steam leaking
from the front of the Statim or water dripping from under the Statim. To change the seal follow
these directions:
1. Place the cassette lid and the new seal on a clean work surface.
2. Examine the position of the old seal in the cassette lid and arrange the new seal in the
same orientation.
3. Remove the old seal with a small screwdriver, sliding it behind the corner of the seal and
pulling the seal from the channel. Clean any residue from the seal channel.
4. Excessively lubricate the new seal using liquid hand soap (provided with new seal).
5. Align the holes in the new seal with the holes in the lid.
6. Install the holes first, then install the four corners allowing the sides to hang out. Be sure
that two indicator squares are visible in each corner.
7. Starting in the middle of along side insert the rounded edge of the seal into the channel.
Work from the middle to one corner, then from the middle to the opposite corner. Install all
four sides the same way.
8. Check to see that the seal is fully inserted into the channel on all four sides. Check the
corners to see that two indicator squares are visible in each corner. Check the two holes to
be sure that they are centered in the cutouts.
9. If there is a small steam leak or water under the unit after installing the new seal try
another cycle. It may take time to seat the new seal. If the leak persists, remove the seal and
reinstall. If unit continues to leak after installing seal for the second time try a new cassette
lid or tray.

Care and Maintenance of the Statim Cassette
Use a non-chloride cleanser (i.e. Cameo, Zud or Bar Keepers Friend) and a green scratch pad. At
least once a week clean the inside of the lid of the cassette and the inside of the tray and the
outside edge of the lower tray. Two or three times a week take some liquid hand soap (not anti-
bacterial) and lubricate all exposed surfaces of the seal, to keep it soft and supple. After cleaning,
rinse and dry, then apply a liberal amount of Stat Dri to the inside metal surfaces. This SciCan
product helps the water dry inside the cassette in less than one minute once the cassette is
removed from the machine. Clean the outside surface of the Statim with a mild soap and water.
The seal in the cassettes will last approximately 800 cycles and if maintained properly could last
longer.

Diagnosing Water Quality Sensor Problems
The water quality sensor detects whether or not there is sufficient water in the
reservoir, monitors conductivity of the water in the reservoir and prevents a
cycle from starting if the water measured is unsuitable. The allowed value of
dissolved solids is 5 ppm or less.
The water quality sensor can fail in one of four ways:
1. The sensor always indicates an empty reservoir.
2. The sensor always indicates a reservoir full of good quality water.
3. The sensor always indicates a reservoir full of poor quality water.
4. The sensor indicates random water quality readings.
A water quality sensor failure is caused by: poor quality water (drain reservoir
