I TEMS NOT SUI TABLE FOR ULTRASONI C CLEANI NG
Soft jew ellery:
pearls, em erald, ivory, coral, agate, sea turtle
shells etc...
As these item s are soft, scratching m ay occur
during the cleaning process.
W elded, plated, glued item s
Ultrasonic cleaning m ay increase the gaps inside
welded joints, plated coating or glue which m ay
lead to breaking loose.
W atches:
unless diving watches with depth rating over 50m
(150 ft)
The strong penetration capabilities of the
ultrasonic waves m ay cause water to penetrate
weaker sealed watches.
Other:
glass, ceram ic, cam era filters with known cracks
Crack size may be increased by the ultrasonic
waves.
4 . Features
•for cleaning of: jewellery, dentures, eyeglasses, electric shaver heads, CDs/ VCDs/ DVDs etc.
•2 colour LED display: 1 to 30 minute tim er, 5 temperature settings, working status indicators
•cooling fan
•two ceramic heaters
•overheating protection
5 . W orking principle
The principle behind ultrasonic cleaning is cavitation.
When the ultrasonic cleaner is switched on, 3-dimensional sound waves of alternating positive
and negative pressure are generated and transm itted into the water in the tank. These sound
waves created m icron-sized bubbles that grow and build up energy during negative pressure and
im plode at a very high speed during positive pressure (43,000 times per second). These
im plosions of high energy bubbles create cavities that literally pull contam inants of the surface
(at speeds up to 400km/ h). Due to the size of the bubbles, they are effective in removing
contam inants from the smallest of crevices but harm less to the substrate itself.
Usually water is used as cleaning agent as it is inexpensive and environm entally safe.

Green: norm al working status, ready.
Red: fault condition, overheated. Let the VTUSC6 cool
down for at least 15 m inutes.
2 On/ off button
Press to switch the device on. Default tim e and
temperature settings are shown (5 minutes, 40°C). Press
again to start the cleaning process; it stops automatically
when the timer expires. Press the button at any tim e to
interrupt the cleaning process.
3 function button
Press to start degassing function (degas). The indicator
[ 4 ] will flash during the degas process (± 2minutes). To
interrupt the process, press the button again. See note
below the table.
4 degas indicator Flashing during the degassing process.
