3. "How often should I change the solution bath?"
How often the solution bath is changed depends on the solution used, frequency of use, and size
of cleaning loads. It is recommended to change your solution every 8 hours at a minimum, or
whenever the solution becomes visibly soiled or dirty.
4. "I've activated the heater option, but the temperature doesn't remain stable. Why
doesn't the temperature remain at a set point?"
Please refer to the section of the manual that describes the heater operation in detail. The
BioSonic UC150 heater option only provides additional energy to the solution to increase the
temperature more quickly than with cavitation alone. It is not designed to maintain a set
temperature or cool the solution to a lower temperature.
5. "I've activated the heater option, but the solution isn't heating."
Please refer to the section of the manual that describes the heater operation in detail. The
BioSonic UC150 heater is only activated when the heater is turned on through the temperature
menu and a cleaning cycle has been activated. The heater will not turn on during a degas cycle or
when the unit is idle.
6. "Why is there a high pitch sound coming from the Ultrasonic Cleaner?"
When a unit is initially filled up with a fresh solution mix there are lots of bubbles in the solution.
If the unit is turned on right after fresh solution is added to the tank, it may make a screeching
sound. Additionally, when placing a basket with instruments into the solutions, air is introduced
and dissolves in the solution, which may create a screeching sound. The noise is present in all
BioSonic cleaners, but is a normal occurrence and is not an indication of any issues with your
device, simply that degas may be required.
To degas, please refer to the section of this manual that describes degassing in detail.
7. "What is degassing and why do I need to do this?"
Before cavitation can become effective in an ultrasonic cleaner the gas trapped in the liquid must
be removed. If it is not removed, the cavitation bubbles will fill with this gas, cushioning the
implosion force. To degas, refer to the section of this manual that describes degassing in detail.
8. "What solution should I be using?"
The purpose of the solution is to break the bonds between the instruments and the soil. Water
alone has no cleaning properties and has high surface tension, which inhibits the cavitation
bubbles from developing. Adding cleaning solution reduces fluid surface tension and contains
ingredients designed to optimize the ultrasonic cleaning process.
Liquid solution allows for instantaneous solution preparation where tablets and powder
solutions must be fully dissolved prior to beginning the cleaning process. It is recommended that
