US cleaner bath filling: Fig.8.0.
For the first time read bath preparation on page 5 again. Plug in mains connector to US bath after you fill in
liquid.
As you know you should NOT switch on ultrasonics without water in the bath!
Preparation of liquid:
Pour distilled water into bath to about 50 mm below the top edge. It will be topped up later. Add 100 ml
isopropy alcohol and 10-15 drops of wetting liquid ( agent). Precise quantities are not important.
Switch on ultrasonic cleaning for 15 minutes and set temperature at 30 deg Celsious ( C). This will prepare
and mix liquid and more important minimise air bubbles in the liquid itself for maximum cleaning effect.
Add or remove some liquid to get desired level of liquid. Fig. 8.0.

Power adjustment:
Full power will create big ripples on the surface- this will mix water and minimise air bubbles.
At some point reduce power for a short time so that only small ripples are visible. Mark that position! This
is the working US cleaning power for record cleaning. With more records in the bath you might increase the
power a little . It is important that you keep the power level in this range but a bit more will be just fine.
Working conditions:
Temperature: 30-33 deg C ( you can experiment up to 40 deg C)
Time: 15 minutes ( but it is not critical if less)
Power: adjust it till ripples are very small on top surface ( about 50-70 % of full power)
Spindle positioning on frame over bath: Fig. 9.0.
We suggest that for first time you use only few old unimportant records to familiarise yourself with the
cleaning process.
Carefully lower the spindle with records onto the frame. Observe the records height and water level ( around
25 mm the top edge of the bath). Observe the edges of bath to fit records in it. Position spindle with tooth
wheel on top of motor tooth wheel. Spindle should neatly sit in the two bearing support. Fig. 9.2. With some
cleaners you might need to reposition spindle positioners by using allen keys-
see Fig. 1.1 &9.5.
Water level should be below record labels. But when more records are submerged the water level will rise a
little. Adjust water level accordingly by adding more water or removing it . Also try readjusting the frame
height. Adjust liquid to raise 5-10 mm below record label. With use check liquid level and add some water
if need it.
