NOTE
Consult the parameter settings and
circuit and terminal diagrams before
installing the control cabinet.
Validate the current media and
process conditions. If the production
conditions are in any way altered after
commissioning of the mixer, a new
validation must be performed.
Validate the possible minimum and
maximum operating speed for each
process.

!
Set VFD unit to 100% nominal
power (kW) and current (A) of the
motor rating.
Excess force may cause magnetic
decoupling.
Electric motors (and VFD system
parts, i.e. sensors) when working
with driven equipment are capable
of causing an explosion in an
explosive atmosphere. Consider
this when selecting parts for the
system in ATEX environment.
Operation
!
Ensure that the installation 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
1. Fill the vessel to a minimum level that
completely covers the mixing head and
the male bearing to provide sufficient
lubrication of the bearing.
2. Start the mixer and slowly increase to
a minimum speed (50 rpm). (Note: the
first 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.)
3. Increase the speed slowly to working
speed. If the mixer makes a rumbling
noise, stop the mixer immediately and
consult the troubleshooting section in this
user guide.
