How Ultrasonic Cleaning Works  
Ultrasonic sound is sound transmitted at frequencies generally beyond  
the range of human hearing. In your ultrasonic cleaner, ultrasonic sound  
(sonics) is used for cleaning materials and parts. This is how it works:  
As the sound waves from the  
transducer radiate through the  
solution in the tank, they cause  
alternating high and low pressure  
areas in the solution.  
During the low pressure stage,  
millions of microscopic bubbles  
form and grow. This process is  
called CAVITATION.  
During the high pressure stage,  
the bubbles collapse or “implode”  
releasing enormous amounts of  
energy. These implosions act like  
scrub brushes, eroding soils,  
away. They work in all directions  
attacking every surface and  
invading all recesses and openings.

Operating Your Cleaner  
If this is the first time you are using the cleaner, please read this whole  
section before proceeding.  
Before You Start Cleaning  
CAUTION  
·
·
·
·
Do not place parts or containers directly on the bottom of the cleaning  
tanks; use a basket, wire hook or other device to suspend items.  
Do not allow the cleaning solution level to drop more than one inch  
below the top of the tank with the cleaner on.  
Do not ever use alcohol, gasoline or flammable solutions. Doing so  
could cause a fire or explosion. Use only water-based solutions.  
Do not ever use mineral acids. These could damage the tank.  
Failure to comply with these cautions will void your warranty.

Getting Ready  
Step Action  
1
Select your cleaning chemistry (check with your chemical  
supplier for solution effects on metals).  
2
Allowing for the volume of the parts you will be cleaning and  
cleaning chemistry, fill the tank with warm tap water to the  
operating level (one inch from the top).  
3
4
5
Add cleaning chemistry to the tank water.  
Plug the cleaner into a grounded outlet.  
For maximum efficiency, refer to page 9, “Optimizing Your  
Cleaner” before proceeding.  
NOTE:  
If this is the first time you are running the cleaner, or if you have changed  
cleaning solution, you must degas the solution. This is done by setting  
the cleaner up for operation and allowing the ultrasonics to drive the  
warm solution for 5-10 minutes This will force out excess gas and assure  
optimum cleaning. You will likely notice a change in the sound of the unit  
as is degasses.  
Cleaning Items  
Step Action  
1
2
Place the items to be cleaned into a basket or perforated tray.  
If using a solid container, add cleaning solution to the container  
to cover the items.  
3
Slowly lower the tray into the tank. Do not allow items to  
contact the tank bottom. Do not stir the solution.  
4
5
When items are clean, slowly remove them from the cleaner.  
Rinse the clean items with fresh water and dry them, if  
necessary.

Optimizing Your Cleaner  
Tanks  
Cleaning - check the tank for contamination whenever you change  
solution. If necessary, remove contaminants with a nonabrasive cloth  
and water.  
Emptying - always unplug the cleaner before emptying the tank.  
Dispose of the contents in an environmentally responsible way.  
Filling - always unplug the line cord before filling the tank. Fill the  
cleaner to the operating level (one inch from the top with beaker/tray in  
place), using warm tap water.  
Low solution level - will cause the cleaner to fail. When you remove  
heavy or bulky loads from the cleaner, the solution level may drop below  
the operating level. If so, be sure to replace lost solution and degas, if  
necessary, depending on the amount used.  
Overload - do not rest any items on the tank bottom. Weight on the tank  
bottom dampens sound energy and will cause damage to the transducer.  
Instead, use a basket or other method to support all items. Allow at least  
one inch between the tank bottom and the parts or receptacle for  
adequate cavitation.  
Covers - allow the cleaner to heat up faster, to a higher temperature,  
and avoid excessive liquid evaporation. However, leaving the cover on  
with heat and ultrasonics can cause the solution to boil, diminishing  
effectiveness.  
Temperature  
Heater - the heater may cause some discoloration of the tank wall. This  
is normal and will not affect the performance of the unit.  
Solution - the fastest method to get your cleaner to the best operating  
temperature is to fill it with warm solution, turn on both the heat and  
ultrasonics, and use a cover.

Application Hints  
First time cleaning - first experiment with one piece, then proceed with  
the remainder.  
Solution level - Be sure to maintain solution level within one inch of the  
tank top. Surface activity will vary with liquid level.  
Load size - It is faster and more efficient to run several small loads  
rather than a few big loads.  
Placing items- Never allow items to sit on the bottom of the tank.  
Always place them in a basket or suspend in the solution.  
Rinsing items- After cleaning, use clean water to rinse away chemicals  
adhering to items.  
Lubricating items- When necessary, re-lubricate items immediately  
after cleaning.  
Drying items - Air drying at room temperature works for some items.  
Place parts requiring faster drying time under hot air blowers or in ovens.  
Please call your local distributor if you have application questions.

Cleaning Solutions  
CAUTION  
Do not use alcohol, gasoline, bleach, mineral acids, solutions with a flash  
point, semi-aqueous or combustible liquids in ultrasonic tanks, or you will  
void the warranty. Only use non-flammable and water-based solutions.  
Solution Types  
Water-based solutions are either slightly acidic or alkaline. They include  
detergents, soaps and industrial cleaners designed to remove specific  
soils.  
Acidic water-based solutions: remove rust, tarnish or scale. They  
range from mild solutions that remove tarnish, to concentrated, inhibited  
acidic solutions that remove investment plaster, milk-stone, zinc oxide  
and rust from steel and cast iron as well as smut and heat-treat scale  
from hardened steel.  
Alkaline water-based solutions: include carbonates, silicates and  
caustics. These cause emulsifying action, which keeps soil from  
redepositing on the cleaned surface, and improves cleaning action in  
hard water.  
Alkaline strength  
Removes:  
Mild  
Light oils and greases, cutting oils and coolant  
compounds.  
Mild to strong  
Heavy-duty  
Heavy grease and oil, waxes, vegetable oils, inks,  
wax or fat-base buffing and polishing compounds,  
milk residues and carbohydrates.  
Mill scale, heat-treat scale, corrosion or oxides.  
11 Operating Your Cleaner  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Change the cleaning solution periodically. Cleaning solutions can  
become contaminated with soil particles which coat the tank bottom.  
This coating dampens the ultrasonic action and reduces cleaning  
efficiency. Certain solutions will cavitate better than others. Contact  
your local distributor for further information.  
Heat and cavitation: increase the chemical activity of cleaning  
solutions. Some materials may be damaged by this stronger chemical  
action. When in doubt, test run samples of items to be cleaned.  
Chemistry Concentrations  
Chemistry concentrations may vary. The amount you use depends on  
the detergent and the type of soil to be removed. Follow instructions on  
the chemistry container and refer to the table below for the effects of  
chemistry on metals.  
Chemicals Harmful to Your Tank  
The following chemicals will harm your ultrasonic tank and the action of  
ultrasonics and higher operating temperatures will increase their  
chemical activity. Do not use these or similar chemicals directly or in  
dilution in your ultrasonic tank or you will void your warranty.

Performance  
Check your cleaner periodically to test the level of activity of the  
ultrasonic cavitation. Frequency of testing will depend on your use of the  
cleaner, however, we suggest running this test monthly.  
Glass Slide Test  
You will need the following equipment:  
·
Frosted microscope glass slide (1” x 3”), such as ESCO #2951F, or  
equivalent;  
·
·
No. 2 lead pencil; and  
General purpose dish detergent.  
Test procedure:  
1. Prepare a fresh solution with general purpose dish detergent  
(concentration 1%) and warm tap water (120º - 140ºF).  
2. Fill the cleaner to within one(1) inch of the tank top.  
3. Turn the ultrasonics on for at least five minutes to allow for degassing.  
4. Prepare the glass slide by first wetting the frosted portion with tap  
water.  
5. With the No. 2 pencil, on the frosted portion make an “X” from corner  
to corner.  
6. Immerse the frosted end of the slide into the solution. Hold the slide  
vertically and center it in the solution.  
7. Turn ultrasonic switch to “On”.  
14 Troubleshooting

The ultrasonics will begin immediately to remove the lead from the slide.  
All lead should be removed within 10 seconds. If your cleaner passes  
this test, its ultrasonic cavitation is acceptable.  
NOTE:  
To ensure consistency from test to test, be sure to repeat  
test conditions - use the same solution concentration, liquid level,  
temperature, type of pencil, length of degassing, etc.  
Service  
With normal use, your Ultrasonic Cleaner should not require servicing.  
However, if it fails to operate satisfactorily, first try to diagnose the  
problem by following the suggestions in the Troubleshooting Guide.  
If you find that your cleaner needs repair, carefully pack and return it to  
your local Service Center. If under warranty, remember to include proof  
of purchase. Your cleaner will be returned by ground service unless you  
specify otherwise.
