Section 1: Introduction
1.1 Introduction
Instead of a few hundred brush–bristles scratching the surface here and there, ultrasound creates millions of
microscopic bubbles that dislodge contamination and foreign matter, even from blind holes, tight joints, pores and
places that cannot be reached by laborious soaking and/or scrubbing. Ultrasound produces these tiny cleaning
bubbles by a process called cavitation.
Now, using your new Cavitator ultrasonic cleaner, you can take full advantage of that remarkable ultrasonic action
called cavitation which gets items cleaner with less effort and time than the next best method: the scrub brush.
You now have the energy to reach and clean even the tightest hidden corners between close–fitting parts that are
otherwise impossible to clean. You can now loosen even strongly adherent foreign particles and rinse them away
in seconds.

Some states do not allow limitations on how long an implied warranty lasts, or the exclusion or limitation of
incidental or consequential damages, so the above limitations or exclusions may not apply to the buyer. This
warranty gives the buyer specific legal rights, and the buyer may also have other rights which vary from state to
state.
Section 2—Operation Instructions
2.1 Precautions
Before you operate you Cavitator ultrasonic cleaner, please review the following precautions.
1. Ground the Unit—Grounding the unit is very important. If not grounded, a strong alternating current tingling
sensation may be encountered by the operator. For added safety, all electrical equipment must be grounded.
2. Three–Prong Plug—Each cleaner is equipped with an line cord with a three–prong plug to provide grounding
for the cleaner. Do not use an adapter to defeat the safety features of this plug.
3. Submersion of Hands in Tank—Although no physiological harm from ultrasonic energy at these frequencies
has been reported, submersion of hands in the tank during operation is not recommended.
4. Do Not Use Acids—Do not use acids in the cleaning tank, or place the tank so that ventilation is inhibited. This
will prevent undesirable effects during the cleaning operation.
5. Do Not Use Flammable Liquids—Ultrasonics may enhance the outgassing of flammable liquids, increasing the
chance of ignition.
6. Electric Shock Hazard—Dangerous voltages are present behind the protective covering. Do not open this
cleaner under any circumstances. Refer servicing to qualified personnel.
7. Cleaning Versus Disinfection—Ultrasound does not sterilize or disinfect objects contaminated with biological
materials.
8. Chlorine Solutions—Chlorine solutions such as chlorine bleach cause corrosive damage to stainless steel tanks.
Do not use chlorine based cleaners.
9. Unplug the cleaner before filling. Do not exceed the MAX mark.
10. Do not touch the wall socket with a wet hand to reduce the risk of electrocution.
11. Follow the instruction manual when using this cleaner. Do not use attachments not recommended by the
manufacturer.
12. Do not immerse the cleaner in water to reduce the risk of electrocution.
13. Never operate this cleaner if cord or plug is damaged. If it is not working properly, damaged or has been
dropped into water, return the damaged cleaner to a service center for examination and repair.
14. Unplug this cleaner immediately after using.
15. Keep the cleaner away from heat, and place it on a dry and level surface.

16. Keep the cleaner in a safe place to avoid falling into water of other liquid.
17. The cleaner should never be left unattended when plugged in.
18. Do not use while bathing.
19. Do not immerse the cleaner into water or other liquid.
20. Do not reach for the cleaner that has fallen into water. Unplug immediately.
2.2 Operating Procedures
1. Open the cover and place the items into the cleaning container, then fill the tank with enough water or
suitable solvent to cover the parts. (The water should cover the item but not exceed the MAX mark! Running
without water can damage the cleaner!)
2. Close the cover. Plug the cleaner into a grounded AC outlet.
3. Right buttons “TIME+” and “TIME-” are the time set buttons. Pressing them will set the cleaning time. Press
the right “ON/OFF” button to start cleaning. The “ON” light will be on and the timer will count down.
4. The Left “TEMP+” and “TEMP-” buttons set the temperature. Pressing them will set the temperature. To begin
heating the water, please press the left “ON/OFF” button, and the “ON” light will then be on.
5. During cleaning the presence of this “hissing” sound is important. It is a sign that your unit is properly
cavitating to produce efficient cleaning bubbles.
6. When cleaning time is over the cleaner will automatically stop, or press the “ON/OFF” button to stop. For
another cleaning cycle, just repeat above process.
7. When cleaning is over, unplug the cleaner. Open the cover, take the cleaned article(s) out.
8. Rinse away excessive loose foreign material before placing parts in the tank. (The spray–rinse attachment, #
510, is designed specifically for this purpose.) This allows the liquid in the tank to stay cleaner for longer
usage.
9. Each time the water is changed, add detergent and run the cleaner for five minutes to drive out the air that is
dissolved in the water which could interfere with the ultrasonic action.
10. Since the cleaners are completely self–tuned and are pre–set and tested at the factory, no adjustments are
necessary.
2.3 Choosing a Cleaning Solution
1. Selection of a proper detergent is important because some detergents inhibit
ultrasonic action and attack the stainless steel tank. To enhance cleaning, use
Cavi–Clean for most cleaning needs. Cavi–Clean is an all–purpose concentrated
detergent formulated especially to increase the cleaning efficiency of your
ultrasonic cleaner. It is gentle to the hands and has a neutral pH. It will not
harm metals or their alloys. Blood cutting agents, a rust inhibitor, and an
excellent wetting and penetrating agent are among its features.
2. Use approximately 1 part Cavi–Clean in 100 parts of water, 1 or 2 ounces (30–
60 ml) per gallon (3.8 liters).
3. The choice of cleaning solutions depends upon the nature of the soil and the
material to be cleaned. Most solvents and all aqueous solutions will support
cavitation at the desirable, powerful low frequencies generated by Cavitator
ultrasonic cleaners.
4. Use Cavi–Clean additive to increase cleaning action to remove metal oxides, stains and to loosen plaster.
Important: use only as an additive to Cavi–Clean detergent because its use with certain other detergents
might cause damage to the cleaning tank or the parts being cleaned.
Add 1 to 3 teaspoons (0.4 to 1.1 cc per liter) Cavi–Clean additive per gallon (3.8 liters) of water with Cavi–
Clean detergent.
Caution: Repeated usage might remove plating from plated parts and damage stainless steel instruments.
Ultrasonic tank damage can be avoided by cleaning in a supplementary glass container (See “Cleaning in
Beakers” below). Extra precautions should be utilized with dissimilar metals. Use only when necessary
because Cavi–Clean detergent will meet most cleaning requirements.
Cavi–Clean

5. While certain solvents will not support direct cavitation at these preferred frequencies, more than ample
power for effective cleaning is transmitted through the metal parts, provided they rest on the bottom of the
cleaning tank.
6. Remember: Do not use acid or chlorine solutions such as chlorine bleach in the cleaning tank.
2.4 Cleaning In Beakers
Many acid solutions and strong solvents may be successfully used by cleaning in auxiliary beakers. The beakers
containing the special cleaning solutions can rest at the bottom of the main cleaning tank. Enough water
containing detergent should be maintained so that the beakers are in at least one inch of water. These glass
beakers may be purchased at any laboratory supply company. Do not use plastic containers for cleaning in your
ultrasonic cleaner.
