1.1 Replacing the Cassette Seal and O-Rings
To ensure optimum performance of the Statim 7000, the seal is equipped with an
electronic tag to ensure only authentic seals are used and also to provide the
user a LCD message to replace the seal after 1000 cycles. The seal and O-rings
should be changed every 1000 cycles or every 12 months.

Replacement seals are available from SciCan (p/n 01-110295S Lid Seal).
When the cassette seal has undergone 1000 cycles, an early message on the
LCD will display SEAL LIFE WARNING - 100 CYCLES REMAINING, with a
warning beep. The seals should be changed immediately. After 1100 cycles, your
unit will stop operating and a message will be displayed SEAL LIFE EXPIRED,
REPLACE. Replacement seals are available from your SciCan dealer.
