Disconnecting the Biocontainer
After the motor has come to a complete stop, remove the clamp connecting the coupler with shaft adaptor. Push
the coupler down away from shaft adaptor by 25-50 mm or 1-2 in. Push the wand down and away from shaft
adaptor until the hex head of the wand is released from adaptor. Use the small bearing on wand for better grip.
Once the hex head of the wand is released, raise the motor up 25-50 mm, or 1-2 in. by rotating the handle on the
top of the motor positioner for a better clearance from the biocontainer. Pull the wand from the sleeve holding the
plastic bushing. Loosen thumb screws on the coupler and slide the coupler out of the sleeve fitting. Lastly, remove
the plastic bushing out of the coupler. The mixer is now ready to accommodate new mixing biocontainer.

Maintenance
Update/restore of software resets the runtime counters and recipe content to zero. 20 RPM.
The Wand Mixer is designed to operate with minimal maintenance. However, to minimize wear it is
recommended that the drive be unplugged if it is not in use for more than 24 hours.
Recipes can be transferred between Wand Mixer units, including the whole recipe library, using external media
(micro SD card).
If user defined library content needs to be transferred back in the unit after service is done it is recommended to
save the recipe library on a micro SD card prior to conducting software service.

Preventive Maintenance
Periodical maintenance is recommended to keep the drive unit in reliable working condition. Wearing of moving
parts can be monitored through the elapsed run time counter in the PLC. Run time information is accessible for
viewing on the touchscreen through the setup menu.
