Introduction
Ultrasonic Cleaners
The ultrasonic cleaner includes nine models with sizes ranging from 2.5 liters thru 25
liters. Each model is constructed using durable industrial style 40 kHz transducers.
These provide increased cleaning power along with built in sweep frequency to ensure
uniform cleaning activity throughout the bath. The five larger sizes have built in drains.
Each model has a digital timer and mechanical thermostat, with a power switch/fuse in
the rear of the machine.
When you first fill your unit, or refill it with fresh solution, use warm water for the
solution. Turn on the heater and turn on the ultrasonics (press the “on/off” touch screen
button, and use the arrow buttons for timing purposes), add the cover, and the solution
will heat quickly to temperature.
Accessories for Your Cleaner
Accessories include a cover and a mesh basket.
Unpacking Your Cleaner
Please check your cleaner and its carton carefully for any external or internal damage. If
you find damage, contact your shipping carrier immediately, before contacting your
distributor. Please retain your packaging for future use.

6
Installing Your Cleaner
Check the plate on the back of the cleaner for correct power requirements. Position your
cleaner within easy reach of a standard grounded electrical outlet. Do not place the
cleaner on a circuit which could become overloaded. Connect the Machine to GFI
outlet.
If your cleaner does not operate correctly, first refer to the troubleshooting section for
possible causes, or contact an authorized service center listed at the back of this
manual, for additional information.

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

7
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.

Operating Your Cleaner
Attention
Machine shuts down automatically if not in use for a prolonged
period of time
If this is the first time you are using the cleaner, please read this whole section
before operating your cleaner! Please be advised that the touch pad panel on the
front of the unit is energy-seeking, and touch-sensitive. It may not work properly
if you push it like a regular button. It is looking for your energy, so try to use the
flat part of your fingertip, and it should respond to the lightest touch.
Operating Your DS2L, DS3L, DS4L and DS6L Cleaners
DEGAS MODE / SWEEP TECHNOLOGY
The Degas mode will expel all of the gasses and/or air out of the water in the tank, for
better cavitation for the ultrasonic power. The Sweep mode will move the cavitation
around in the tank in a more uniform fashion making the ultrasonic cavitation more
efficient. Once you utilize these buttons on the machine, you will see the U turn to a D

Draining Your Cleaner
Warning
Do not immerse the cleaner in water.
Unplug the cleaner from the power source.
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.
Optimizing Your Cleaner
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.
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.
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.

12
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.

13
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
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.
oTwo completely different cleaning solutions.
oOne beaker or tray with a cleaning solution and one with a rinse solution.
•Cleaning solution in your tank needs to be changed less often.

14
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 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 grease and oil, waxes, vegetable oils, inks, wax or fat-
base 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.
