When the chamber is filled with noncorrosive glycol, it does not need to be cleaned
periodically.
When changing the liquid inside the chamber from glycol to water, the inside of the
chamber must be cleaned to remove all traces of glycol before filling it with water.
Before the acoustic wheel can be cleaned, it must be removed from the RollerFORM
and emptied of liquid, and the probe must be removed. The necessary procedures are
contained in the following sections:
• “Emptying the Acoustic Wheel’s Liquid Chamber” on page 74
• “Removing the Acoustic Wheel from the RollerFORM Scanner” on page 71
• “Removing the Probe from the Acoustic Wheel” on page 77
To clean the acoustic wheel’s liquid chamber
1. Remove the four external retaining screws from the plain flange of the acoustic
wheel, which is opposite to the probe-cable side flange (see Figure 6-14 on
page 87).
When removing the screws from the plain flange, be careful not to lose the screw
gaskets.
