Safety Precautions
Before using your Ultrasonic Bath, please read and thoroughly
understand these safety precautions. Failure to follow them may result in
serious personal injury or property damage.
To avoid electrical shock:
• Do unplug from power source before filling or emptying the tank.
• Do plug the unit into an appropriate grounded power socket.
• Do connect the unit to a power supply using a properly sized
overcurrent protection device. See label on the back of unit for
information on current rating.
• Do keep the control panel and the area around the unit clean and
dry—wipe up solution which spills over the tank brim. Water and high
voltage can cause electrical shock.
• Do not operate the unit without proper grounding.
• Do not remove the grounding prong on the line cord plug.
• Do not disassemble your unit—high voltage inside the unit is
dangerous.
• Do not immerse the unit in water.
To prevent personal and/or property damage:
• Do 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 (158 °F).
• Do not place your fingers or hands into the tank while the unit 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.
1
To prevent damage to the unit:
• Do change your solution regularly.
• Do not cover vents on the cover.
• Do not operate the unit dry.
• Do not place parts or containers directly on the bottom of the tank; use
a tray or wire to suspend items. Failure to comply may cause
transducer damage and will void your warranty.
• Do not allow the solution to drop more than 3/8 inch (1 cm) below the
operating level line with heat or ultrasonics on. Failure to comply may
cause transducer and/or heater damage and will void your warranty.
Sound level and energy savings
• Do not operate the unit without a cover when possible
• The sound pressure released by the unit depends on the size of the
bath and the application, but is less than 80 dBA when used with a
cover.
• To reduce the sound pressure it is recommended to use a cover while
ultrasonics are activated and to switch the ultrasonics on with the bath
loaded when possible.

Introduction
Ultrasonic Baths
This line of ultrasonic baths includes five sizes:
Tank Ca pa c i t y
1/2 gal. (1.91 l)
3/4 gal. (2.81 l)
1-1/2 gal. (5.71 l)
2-1/2 gal. (9.51 l)
5-1/2 gal. (20.81 l)
Each model is constructed using durable industrial style 40 kHz
transducers. These provide increased ultrasonic power along with built in
sweep frequency to ensure uniform ultrasonic activity throughout the bath.
Models with tank capacity ½ gal. and ¾ gal. have a molded dip in the left
side of their rims to facilitate emptying of solution from the tank. with tank
capacity 1-½, 2-½, 5-½ gal. have built in drains and are supplied with tank
drain kits. Each model can be purchased in four different configurations:
• with a Mechanical Timer (M);
• with a Mechanical Timer plus Heat (MH);
• with Digital Control and Timer (CPX);
• with Digital Control, plus Heat and Timer (CPXH).
When you first fill your unit, or refill it with fresh solution, use warm water
for the solution. Turn on the heater (if available), turn on the ultrasonics
(press the Sonics key or rotate the Timer), add the cover and the solution
will heat quickly to temperature.
3 Introduction
Accessories For Your Unit
As parts cannot be placed on the tank bottom, accessories include
beaker positioning covers, solid and perforated insert trays, mesh
baskets, beakers, and support racks.
NOTE: Tank covers are included with every unit.
Unpacking Your Unit
Please check your unit 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.
Installing Your Unit
Check the plate on the back of the unit for correct power requirements.
Position your unit within easy reach of a standard grounded electrical
outlet. Do not place the unit on a circuit which could become overloaded.
If your unit does not operate correctly, first refer to the troubleshooting
section on page 45 for possible causes, or call for service and additional
information.
4 Introduction
How Ultrasonics Works
Ultrasonic sound is sound transmitted at frequencies generally beyond
the range of human hearing. In your ultrasonic bath, ultrasonic sound
(sonics) can be used for cleaning materials and parts, and for dissolving,
homogenizing and degassing liquids. This is how it works:
• As the sound waves from the
transducer radiate through the
solution in the tank, they cause
alternating high and low pressures
in the solution.
• During the low pressure stage,
millions of microscopic bubbles
form and grow. This process is
called CAVITATION, meaning
“formation of cavities”.
• During the high pressure stage,
the bubbles collapse, or “implode”
releasing enormous amounts of
energy.
• For ultrasonic cleaning
applications, these implosions act
like an army of tiny scrub brushes.
They work in all directions,
attacking every surface and
invading all recesses and
openings.
• This same energy can be used for
other applications, such as liquid
dissolving, homogenizations, and
degassing.

35 Operating Your Ultrasonic Bath
Optimizing Your Ultrasonic Bath
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 unit before emptying the tank. Empty the
solution into a waste disposal unit.
Filling - always unplug the line cord before filling the tank. Fill the tank to
the operating level (with beaker/tray in place), using warm tap water.
Low solution level - will cause the unit to fail. When you remove heavy
or bulky loads from the tank, 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 unit to heat up faster, to a higher temperature, and
avoid excessive liquid evaporation. However, obstructing the cover vents
will cause the unit to overheat.
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 ultrasonic bath is to fill with
warm solution, use heat, ultrasonics (which also adds heat), and a cover.
Approximate stabilization temperatures with ultrasonics and heat running
continuously:
MH unit without a cover 50 °C (122 °F)
MH unit with a cover 62 °C (144 °F)
continued...
36 Operating Your Ultrasonic Bath
Over temperature protection (CPXH only) - the unit will shut down at
75 °C (167 °F) and display will go blank with only the Alarm icon
remaining on. Turn the unit off and allow it to cool down. For a faster
cooldown, replace some of the warm solution with cold solution.
Solution Temperature Measurement
The following instructions provide an accurate method to obtain
consistent thermal measurements using a calibrated temperature
measurement instrument. These readings can be used for cleaning
process control or to verify the accuracy of the CPXH temperature
readings.
Step Action
1 Ensure that sonics and heaters are off.
2 Stir the solution for 15 seconds to ensure thermal uniformity.
3 For CPXH models, wait 2 minutes after turning the unit on
before taking measurements. This allows for the display to be
properly updated.
4 Suspend a thermocouple in the bath without allowing the probe
to touch the tank walls.
Solution
Solution activity - the amount of visible activity is not necessarily related
to optimum cavitation for cleaning.
Degassing 1 - fresh solutions contain many dissolved gases (usually air),
which reduce effective ultrasonic action. Although solutions will naturally
degas over time, using Degas Mode speeds up the degassing process.
Solutions that have been sitting unused for 24 hours or longer have
reabsorbed some gases.
Degassing 2 -degassing mode is also used where gas has to be
removed from liquids or samples.
Heat - increases the chemical activity of cleaning solutions.
Solvents - never use solvents. Vapors of flammable solutions will collect
under the unit, where ignition is possible from electrical components.
37 Operating Your Ultrasonic Bath
Surface tension - can be reduced by adding solution to the bath.
Reduced surface tension will increase cavitation intensity and enhance
cleaning.
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.
38 Operating Your Ultrasonic Bath
Application Hints
• Never clean novelty or inexpensive jewelry in the ultrasonic bath.
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 ultrasonic bath.
First time cleaning - first experiment with one piece, then proceed with
the remainder.
Solution level - Be sure to maintain solution level within 1/2 inch (1.3 cm)
of the tank’s “operating level” line. 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-lubricate 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.
Please call your local distributor if you have application questions.

Cleaning Methods
ITEMS IN PERFORATED

ITEM
SUSPENDED
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
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.
40 Operating Your Ultrasonic Bath
Indirect Method
SOLID INSERT TRAY
BEAKER POSITIONING TRAY
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 unit. 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.
- two completely different cleaning solutions.
- 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.
41 Operating Your Ultrasonic Bath
Cleaning Solutions
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 waterbased solutions.
Solution Types
Water-based solutions can be 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, 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.
42 Operating Your Ultrasonic Bath
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.
Acetophenone Chloracetic Acid Hydrocyanic Acid
Aluminum Chloride Chloric Acid Hydrofluoric Acid
Aluminum Fluoride Chlorine, Anhydrous Hydrofluosilicic Acid
