INTRODUCTION
Ultrasonic cleaning is based on a cavitation effect caused by
high frequency ultrasonic wave vibrations in fluid. Microscopic
bubbles are formed and implode (cavitation) which provides
an intense scrubbing action on the surface of the item being
cleaned. Additionally, the bubbles are small enough to
penetrate even microscopic crevices, cleaning them thoroughly
and consistently.
Although this digital series of ultrasonic cleaners is very easy to
use, to get the best performance from your new purchase we
recommend you read this manual before beginning cleaning. It
contains important safety information as well as practical hints
for usage.
GENERAL GUIDELINES

Replace if it becomes damaged in any way.
