Operation
Ensure that the insta • llation has been performed correctly and that the
parameters are correctly programmed.
Ensure that no one is working inside the vessel. •
Ensure that a sufficient level of liquid covers the mixing head and the male •
bearing to ensure sufficient lubrication of the bearing.
The mixing head must be covered with liquid during operation with explosive media. •
Never work close to the drive unit while it is connected to its driving source. •
Keep away from moving parts.
Regulate speed, acceleration, and deacceleration carefully to avoid magnetic •
decoupling.
Stop the mixer immediately if any signs of malfunction, abnormal noise, or •
smell occurs.
Do not exceed operation temperature of 135 ºC (275 ºF) inside vessel. •
Use extra precaution because of pressure buildup when the mixer is running at •
high speed and:
with hot WFI •
at atmospheric pressure •
during or after steam sterilization •
Starting the Mixer
Fill the vessel to a minimum level that completely covers the mixing head and the 1.
male bearing to provide sufficient lubrication of the bearing.
Start the mixer and slowly increase to a minimum speed (50 rpm). (Note: the first 2.
time the mixer is started, run it for a few seconds at this speed and check that the
motor fan is turning in the correct direction.)
Increase the speed slowly to working speed. If the mixer makes a rumbling noise, 3.
stop the mixer immediately and consult the troubleshooting section in this user
guide.
Operating Notes:
Fill the vessel with liquid before adding solid material. •
Always ensure that the mixing head is always completely covered with liquid •
during all ATEX operation.
For ATEX operation during draining, stop the mixer before the liquid level •
reaches below the top of the mixer. This will ensure the mixer is not run dry. If
the mixer has been run dry, turn off the mixer and inspect the bearings. Consult
the troubleshooting section.
Avoid buildup of large quantities of solids on the bottom of the vessel. •
