Preparing the RollerFORM Liquid Chamber

5. Turn the RollerFORM probe-cable side up, so that the acoustic wheel is at an
angle, and the OUT valve is at the highest possible position. This allows all the air,
and the air bubbles that may form, to be released from inside the acoustic wheel.
6. While the acoustic wheel is filling with liquid, lightly tap and shake the acoustic
wheel to remove all air bubbles. Take special care to remove the bubbles that are
adhering to the interior surface of the liquid chamber. If left in place, these
bubbles may interfere with the propagation of ultrasound waves.
When the bubbles are freed inside the liquid chamber, they should migrate
toward the OUT valve, and then exit the valve.
