precautions. Failure to follow them may result in serious personal injury or property damage.
To avoid electrical shock:
• Unplug from power source before filling or emptying the tank.
• Keep the control panel and the area around the cleaner clean and dry -- wipe up solution
which spills over the tank brim. Water and high voltage can cause electrical shock.
• Do not operate the cleaner without proper grounding.
• Do not remove the grounding prong on the line cord plug.
• Do not disassemble your cleaner -- high voltage inside the cleaner is dangerous.
• Do not immerse the cleaner in water.
To prevent personal and/or property damage:
• Operate the cleaner with a vented cover or no cover.
• Use water-based solutions.
• Do not ever use alcohol, gasoline, or flammable solutions. Doing so could cause a fire or
explosion and will void your warranty. Use only water-based solutions.
• Do not ever use mineral acids. These could damage the tank.
• Do not touch the stainless steel tank or cleaning solution -- they may be hot.
• Do not allow fluid temperature to exceed 70°C (160°F).
• Do not place your fingers or hands into the tank while the cleaner is operating. Doing so
may cause discomfort and possible skin irritation. Avoid contact with solutions and provide
adequate ventilation.
• Do not use solutions containing chlorine bleach.
To prevent damage to the cleaner:
• Change your solution regularly.
• Do not cover vents on the housing.
• Do not operate the cleaner dry.
• Do not place parts or containers directly on the bottom of the cleaning tank; use a tray or
wire to suspend items. Failure to comply may cause transducer damage and will void your

How Ultrasonics Work
Dirty items come clean in ultrasonic cleaning systems when millions of superheated
bubbles scrub grime and oxidation away with stunning results. How? Through the process
of de-cavitation.
Ultrasonic cleaning systems send high frequency sound waves ripping through an
ultrasonic cleaning solution leaving superheated bubbles in the waves’ wake. When these
bubbles, called cavitations, collapse, called decavitation, the heat and energy of their
implosions work with the specially formulated ultrasonic cleaning solution to remove dirt,
oils, residue, and oxidation from the surface of the contaminated item.
Imagine the ability to get into the tiniest of nooks and crannies where dirt and grime hide,
and then imagine scrubbing that surface ultra clean. With conventional cleaning – brushes,
rags and elbow grease – this task seems impossible. But the cavitating cleaning action of
an ultrasonic cleaning system does just that – It goes where brush bristles can’t.
What is Ultrasonic Cleaning Technology?
Ultrasonic cleaning technology is high frequency sound waves creating a phenomenon in a
fluid called cavitating action, or cavitations. Cavitations, the superheated bursting of
bubbles in a fluid, are what make ultrasonic cleaning work.
How Can Sound Waves and Ultrasonic Cavitations Clean?
When a sound wave travels through fluid, it stretches and compresses the fluid to transmit
sound. When the sound wave's amplitude increases to a threshold level, when the fluid
cannot hold the “stretch” of the sound wave, the sound wave energy literally tears the water
apart and vacuum bubbles are formed.
Each vacuum bubble grows in size until it can grow no more – equilibrium is reached
between the bubble and the fluid – at equilibrium, the bubble is compressed by the
surrounding fluid pressure until it collapses. At collapse, a tiny liquid jet is created in the
bubble’s place.
Each liquid jet creates estimated temperatures and pressures of over five thousand
degrees Celsius and ten thousand PSI when the collapse occurs. The extreme pressure
and temperature of the jet provides the phenomenon responsible for the effective ultrasonic
cleaning action. This action occurs millions of times, over and over, while the sound waves
are traveling through the fluid.
Ultrasonic Cleaning Cleans Every Nook and Cranny
When the item being cleaned is submerged in the ultrasonic tank’s fluid, the millions of jets
created by ultrasonic energy are capable of reaching into fine depressions and intricate
details. Every surface area is exposed to the ultrasonic cleaning action; cracks, crevices

and hard to reach corners of every nook and cranny get cleaned by the ultrasonic cavitating
action. Ultrasonic sweep cleaning technology enhances the system’s ability to clean.
Ultrasonic Cleaning Power and Frequency
Ultrasonic system power is rated in how much energy, in watts, is generated in the
ultrasonic tank. Higher power systems generally mean shorter part immersion times in the
fluid.
The ideal cleaning frequency is determined by the size of dirt being cleaned. Simply
speaking, higher frequencies are more capable it is of removing smaller particles, lower
frequencies are better suited for large dirt particles. Many SharperTek® ultrasonic systems
can be configured with multi-frequency technology, giving you the benefit of multiple
cleaning frequencies in a single design package.

Warning
Do not immerse the cleaner in water.
Unplug the cleaner from the power source.
0.7L, 2L, 3L, 4L, and 6L models do not have a drain. To empty, use the side of the rim to
pour the used solution into a waste disposal unit, rinse the tank thoroughly and refill with
new solution.
The 10 Liter, 15 Liter (4 gallon), 17 Liter, 28 Liter (7.5 gallon), and 46 Liter (18 gallon)
models include a drain. (Drain not attached. Thread sealant and do not over tighten.)
Step
Action
1
Place the cleaner to allow easy reach of the drain tube into a waste disposal
unit.
2
Remove the thread protecting cap from the end of the cleaner's drain pipe.
This will expose the white Teflon sealing tape on the drain pipe's threads.
3
Hand tighten the drain valve onto the drain pipe over the white Teflon sealing
tape. Finish tightening the valve in place using on adjustable or a 21mm
wrench. Tighten the valve no more than one full turn when using the wrench
until the handle is on top.
CAUTION: Over tightening of the valve can cause damage to the ultrasonic
tank. Always use Teflon sealing tape or a sealing paste designed for use
with stainless steel if retightening or refitting of the drain valve is required.
4
Hand tighten the hose adaptor into the end of the drain valve. Slide the drain
tube over the barbed hose adaptor end.
5
Close the drain valve by turning the handle perpendicular to the valve body
and the cleaner is ready to fill with solution. To open the valve and drain the
cleaner, turn the handle so that it is in line with the valve body.
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. Empty the solution into a
waste disposal unit.
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.
Page 13

Lenexa, KS 66214 USA
Phone: 913-685-0675
Fax: 913-685-1125
www.ndtsupply.com
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 tray and/or beaker
positioning cover to support all items. Allow at least one inch between the tank bottom and
the beaker or receptacle for adequate cavitation.
Covers - allow the cleaner to heat up faster, to a higher temperature, and avoid excessive
liquid evaporation.
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 heat your cleaner is to fill with warm solution, use heat,
ultrasonics (which also adds heat), and a cover.
Solution activity - the amount of visible activity is not necessarily related to optimum
cavitation for cleaning.
Degassing - fresh solutions contain many dissolved gases (usually air), which reduce
effective ultrasonic action. Although solutions will naturally degas over time. Solutions that
have been sitting unused for 24 hours or longer have reabsorbed some gases.
Heat - increases the chemical activity of cleaning solutions.
Surface tension - can be reduced by adding solution to the bath. Reduced surface tension
will increase cavitation intensity and enhance cleaning.
Solvents - never use solvents. Vapors of flammable solutions will collect under the cleaner,
where ignition is possible from electrical components.
Renewal- replace cleaning solutions often to increase ultrasonic cleaning activity.
Solutions, as with most chemicals, will become depleted over time. Solutions can become
contaminated with suspended soil particles which coat the tank bottom, inhibiting ultrasonic
activity.

Application Hints
CAUTION
Never clean novelty or inexpensive jewelry in the cleaner. The combination of heat and
vibration may loosen a cement-held setting.
Never clean gemstones such as emerald, amethyst, pearl, opal, coral, turquoise,
peridot or lapis lazuli in the cleaner.
First time cleaning - first experiment with one piece, then proceed with the remainder.
Solution level- Be sure to maintain solution level within 1 ½” of top of the tank. Surface
activity can 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
tray or beaker or suspend in the solution.
Rinsing items - After cleaning, use a clean water bath to rinse away chemicals adhering to
items.
Lubricating items - When necessary, re-Iubricate 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.
Cleaning Methods
There are two methods of cleaning - direct and indirect. Each has advantages and
disadvantages. When in doubt, run test samples using both methods to decide which one
produces the best results for you.
Direct method
• Items in perforated insert tray
• Item suspended
Page 15

Lenexa, KS 66214 USA
Phone: 913-685-0675
Fax: 913-685-1125
www.ndtsupply.com
How it works:
• Fill the tank with warm water and a cleaning solution.
• Place the items to be cleaned in a perforated tray and lower them into the tank. You
can also suspend items on a wire and then immerse them in the solution.
The advantages of this method are the simplicity of operation and cleaning effectiveness.
Indirect method
• Items laid randomly in solid insert tray
• Items placed in beakers
How it works:
• Fill the tank with warm water and a cleaning solution.
• Pour your solution medium into one or more beakers or into a solid insert tray.
• Place the beakers in a beaker positioning cover or a solid insert tray to fit your cleaner.
Beakers should not touch the tank's bottom.
The advantages of this method are:
• Removed soil stays in the beaker or tray so you can easily examine, filter or discard it.
• You can use one or more solutions at the same time.
o Two completely different cleaning solutions.
o One beaker or tray with a cleaning solution and one with a rinse solution.
• Cleaning solution in your tank needs to be changed less often.
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 solutions 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, and inhibited acidic solutions that remove investment
plaster, milk-stone, zinc oxide and rust from steel and cast iron as well as smut and heattreat scale from hardened steel.

Fax: 913-685-1125
www.ndtsupply.com
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 grease and oil, waxes, vegetable oils, inks, wax or fatbase
buffing and polishing compounds, milk residues and
carbohydrates.
Heavy-duty
Mill scale; heat-treat scale, corrosion or oxides.
Change the cleaning solution periodically. Cleaning solutions can become contaminated
with suspended 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. Caustic solutions: used to remove rust from steels, metal alloy
corrosion and a variety of tenacious soils.
Solution Amounts
Solution amounts may vary. The amount you use depends on the detergent and the type
of soil to be removed. Follow instructions on the solution container and refer to the table
below for the effects of solutions 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.
