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.

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 pl

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—Ultrasound 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

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! Runn
witho
ut 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
hea
ting the water, please press the left “ON/OFF” button, and the “ON” light will then be on.
5.
Turn the control knob to adjust to the power.
6.
During cleaning the presence of this “hissing” sound is important. It is a sign that your unit is properly
c
avitating to produce efficient cleaning bubbles.
7.
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 proce
8.
When cleaning is over, unplug the cleaner. Open the cover, take the cleaned article(s) out.
9.
Rinse away excessive loose foreign material before placing parts in the tank. (The spray–rinse attachment, #
5
10, is designed specifically for this purpose.) This allows the liquid in the tank to stay cleaner for longer
usage.
10.
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

Since the cleaners are completely self–tuned and are pre–set and tested at the factory, no adjustments are

2.3 Maintenance
1.
Unplug and empty the unit after using. (Do not keep water in the tank for a long time.)
2.
Wipe the tank and housing with dry towel. (Do not wash the unit with water to avoid electric shock.)
3.
Keep in cool and dry place.
2.4 Choosing a Cleaning Solution
1.
Selection of a proper detergent is important because some detergents inhibit
ultr
asonic 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
arm metals or their alloys. Blood cutting agents, a rust inhibitor, and an
h
excellent wetting and penetrating agent are among its featur
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
m
aterial to be cleaned. Most solvents and all aqueous solutions will supp
c
avitation 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–

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.
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

2.5 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.
