Bath fluid safety features
The miniAV-X Bath Unit is
equipped with a fluid level float
sensor suspended from the top
bath flange at the front of the
bath. If the bath fluid level drops
to an unacceptable level, a fluid
level float warning will abort
bath operations until an accept-
able bath fluid level is restored
and the miniAV-X is restarted.
Over-temperature thermistor The miniAV-X Bath Unit incorporates a thermal fuse suspended in the
bath fluid from the top bath flange. If the bath fluid temperature rises
above acceptable operating temperatures, the thermal fuse will abort bath
operations. if this occurs contact Cannon Service.
Checking solvent levels
Frequently inspect the user-supplied solvent vessel to ensure a steady
supply of cleaning solvent for the viscometer tubes. When the solvent
level drops to within 2.5-5.0 cm (1-2") of the bottom of the solvent
vessel, it should be refilled.
Solvent/drain lines
See the Installation section of the first chapter for information on solvent/
drain lines for the miniAV-X instrument.
