2.6QTH-D Ultrasonic Operating Procedures & Manual
untreated condition. Typically, items such as gold, silver, platinum,
diamonds, rubies, sapphires etc., are safe for ultrasonic cleaning.
For more specific information on which stones are suitable for cleaning
in an ultrasonic, we suggest you contact a gemologist or GIA (The
Gemological Institute of America). Also, please reference the chart
on page 13 which indicates the gemstones that may be suitable
to be cleaned in an ultrasonic.
Do not submerge non-waterproof watches in any ultrasonic, as
damage to the watch may occur. If you choose to submerge a
waterproof watch in an ultrasonic, always make sure the watches
stem is fully inserted and tightened all of the way in. Also, be
aware that if the gasket in the watch case is faulty, you may
inadvertently damage the watch due to exposure to moisture.
However, to be safer, it may better to carefully submerge
only the metal watchband into the tank for a brief cleaning while
being certain not to submerge the head of the watch at any time. At
your own risk, before attempting this, again always be certain the
watches stem is fully inserted and/or tightened all of the way in.
TYPICAL DEGASSING PERIOD FOR SOLUTION
Water that has not been degassed will result in the cavitation (action)
of the ultrasonic appearing very slow or flat. Degassing is the natural
process of removing gasses from any tank solution being affected
by ultrasonic sound waves. Running the DEGAS function will
speed up the natural process of degassing. Depending on the
solution you are mixing with the water in your unit, the natural degassing
time may vary from less than five (5) to as much as fifteen (15) minutes
depending upon factors such as temperature and soap content.
The rule of thumb is that the thicker and slimier the solution is,
the less time the degassing process will take. Degassing occurs
whenever you first use your ultrasonic with fresh water/solution and
will recur each time you add to or change your water or
solution. By pressing the DEGAS button, you will speed
up the degassing time to only a few minutes.
