Introduction
Ultrasonic Cleaners
These XPD-Series line of ultrasonic cleaners includes four models with sizes ranging
from 11 to 30 liter. Each model is constructed using durable industrial style 32/40 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, set timer and turn on the ultrasonic (press the ON/OFF
touch screen button, and use the arrow buttons for timing purposes), place the cover,
and the solution will heat to temperature.
Accessories for Your Cleaner
Accessories include a cover and a mesh basket. 8 liter unit has drain.
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. Take pictures of any damage
while machine is still in the crate.
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.

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 (aka cavitation’s) collapse (de-cavitation), 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.

7
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 Sweep Cleaning Technology
Ultrasonic sweep cleaning “sweeps” multiple ultrasonic frequencies through a single
ultrasonic tank. This sweeping controls the creation of standing waves, allowing no
single frequency to resonate in the tank thus eliminating the root cause of standing
waves, and tank dead spots.
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.

CAUTION!
•Do not place parts or containers directly on the bottom of the cleaning tanks; use a
tray or wire to suspend items.
•Do not allow the solution to drop more 1 ½” from top of tank.
•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.
Attention

Before You Start Cleaning
Step
Action
1
Select your cleaning solution (refer to “Cleaning Solutions” section)
2
Consider the volume of the parts you will be cleaning. With parts, solution
should reach operation level line (one inch from the top)
3
Add cleaning solution to the tank of water
4
Plug the cleaner into a ground outlet

Operating Your Cleaner
If this is the first time you are using the cleaner, please read this whole section
before operating your cleaner!
1. Plug in your machine and flip on the On/Off control switch in the back of the unit.
2. Fill the machine with your water/chemicals. Pay close attention to the
directions for temperature and duration from the chemicals SDS information
paperwork (Included in your package or available on our website).
3. Remove the basket put the lid back on the unit..
4. First set the desired temperature by pressing the up arrow “temperature
button” Second set the ultrasonic cycle time by pressing on the time up
arrow “time button”. After setting the temperature and the time, press the
ON/OFF middle button to start the unit.
5. Keep the basket out and the lid on while it is heating up to quicken the
waiting period. You can also run the ultrasonic for an additional 10
degrees perhour.
6. Place the basket back into the unit with parts for cleaning.
7. When the cleaning cycle is complete, you can rinse the parts in the sink, and
dry. Strain the chemicals with a cheese cloth to keep them fresh for the next
cleaning.If you are removing oils, you can find an “oil diaper” online for
reasonable price and quantity. This can be placed on the water surface and
will absorb the oils. This way the parts will not be coated again once the
cleaning is complete. We do not offer the cheese cloths or the oil diapers.
AUTOMATIC DEGAS /
SWEEP TECHNOLOGY
This unit has automatic degas and sweep technology, the first 5 minutes of usage.
The Degas will expel all the gasses and/or air out of the water in the tank, for better
cavitation for the ultrasonic power. The Sweep will move the cavitation around in the
tank in a more uniform fashion making the ultrasonic cavitation more efficient.
ON/OFF

10
Warning
Do not immerse the cleaner in water.
Unplug the cleaner from the power source.
Draining Your Cleaner
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 to a higher temperature, faster and reduces
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.
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 somegases.

11
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.
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
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.

12
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 thewarranty.
Only use non-flammable solutions and water-based solutions.
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 asolid
insert tray.
•Place the beakers in a beaker positioning cover or a solid insert trayto
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 easilyexamine,
filter or discard it.
•You can use one or more solutions at the same time.
•Two completely different cleaning solutions.
•One beaker or tray with a cleaning solution and one with arinse
solution.
•Cleaning solution in your tank needs to be changed less often.
Cleaning Solutions

13
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.
Troubleshooting
If your cleaner does not operate satisfactorily, please check the tables below for
possible causes before calling your authorized service center.
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.
