7. Keep filling the acoustic wheel until a little liquid flows out of the OUT valve, and
then close the OUT valve, and then immediately close the feeding tube valve on
the pump.
When the liquid chamber is filled with noncorrosive glycol, follow all pertaining
safety and environmental measures, and take special care to thoroughly clean any
glycol that may spill on the acoustic wheel, on other parts of the scanner, or on any
other surface.
8. Remove the remaining air bubbles. See “Removing Air Bubbles from the Liquid
Chamber” on page 47.
The acoustic wheel’s liquid chamber is properly filled when the RollerFORM is sitting
on a flat surface without any downward pressure applied on the handle and a gap
measuring 2 mm to 3 mm (0.08 in. to 0.12 in.) remains between the black acoustic
wheel flanges and the surface to inspect (see Figure 3-5 on page 47). If the gap is
larger, remove some glycol or water by opening the OUT valve and letting some
liquid out of the liquid chamber. Then, measure the gap again. Repeat this operation
until the gap between the black acoustic wheel flanges and the surface to inspect is
between 2 mm and 3 mm (0.08 in. to 0.12 in.).
