"Changing pressure pod seals" on page 10-4.
Check the disposable tubing set for leaks. If the set does not leak, press CONTINUE. If the set leaks, replace it
with a new set and prime the set.
If the alarm recurs, replace the disposable tubing set.
Note the alarm message. Discontinue the procedure. Notify a qualified service technician of the alarm

This alarm occurs only during Prime mode, when the Spectra system
tests the AC pump. It occurs when the AC pump fails to develop
sufficient pressure as measured by the access pressure sensor.
