1.1 Safety Requirements and Warnings

This chapter contains an explanation of the different Safety Notice symbols and icons
found both in this manual and on the product itself and provides additional safety
information for ultrasonic welding. This chapter also describes how to contact Branson for
assistance.

2 100-214-294 REV. 05

1.2 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.

1.2.1 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

1.2.2 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

1.2.3 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

• Turn off AC and heater switch before plugging/unplugging the line cord

1.2.4 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

1.2.5 Insulation resistance test

Branson has taken all applicable measures to assure that manufactured units comply with
insulation resistance requirements, as outlined by IEC 61010-1:2010 (Third edition). As

100-214-294 REV. 05 3

per the Portable Appliance Testing (PAT) requirements, testing should be carried out by
the user.

Before doing the insulation testing, however, please read the following pertinent
information:

All of Branson's 220 V "C" and 230 V "E" units are equipped with Metal Oxide Varistors
(MOVs) as the primary components to absorb overvoltages in the power line. MOVs
disperse the over-voltage to the ground line and thus away from the equipment. Per their
mode of operation, these MOVs will cause the insulation resistance test to fail when it is
carried out at 500 V DC. As such, Branson recommends performing the test at a reduced
voltage (250 V DC), as allowed by the Code of Practice for In-service Inspection and
Testing of Electrical Equipment published by the IET (The Institution of Engineering and
Technology), as this will prevent the MOVs from triggering and failing the test.

4 100-214-294 REV. 05

1.3 Limited Warranty

Subject to the limitations outlined below, Branson warrants that the Ultrasonic Baths will
be free from defects in material and workmanship under normal use and regular service
and maintenance for a period of twenty four (24) months from the date of
shipment. Branson does not warrant that the operation of the software shall be
uninterrupted or error free. THIS IS THE SOLE AND EXCLUSIVE WARRANTY GIVEN WITH
RESPECT TO THE ULTRASONIC BATHS AND IS IN LIEU OF AND EXCLUDES ALL OTHER
WARRANTIES, EXPRESS OR IMPLIED, ARISING BY OPERATION OF LAW OR OTHERWISE,
INCLUDING WITHOUT LIMITATION, MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE WHETHER OR NOT THE PURPOSE OR USE HAS BEEN DISCLOSED TO BRANSON.

This warranty does not extend to any losses or damages due to misuse, accident, abuse,
neglect, normal wear and tear, negligence (other than Branson's), unauthorized
modification or alteration, use beyond rated capacity, unsuitable power sources or
environmental conditions, improper installation, repair, handling, maintenance or
application or any other cause not the fault of Branson. If within thirty (30) days after
discovery of any warranty defects within the warranty period, the Customer notifies
Branson thereof in writing, Branson shall, at its option and as the Customer's exclusive
remedy, repair, correct or replace, or refund the purchase price for, that portion of the
product found by Branson to be defective. Failure by the Customer to give such written
notice within the applicable time period shall be deemed an absolute and unconditional
waiver of the Customer's claim for such defects. The Customer must return the product to
one of the Branson service centers, whose addresses are provided on 7.4 Service Centers
of this manual. The Customer will be responsible for freight sending the unit to the service
center. The service center will send the unit back to the Customer with freight prepaid.
Branson’s liability, whether based on warranty, negligence, tort or strict liability, or other
cause, arising out of and/or incidental to sale, use or operation of the transducer
elements, or any part thereof, shall not in any case exceed the cost of repair or
replacement of the defective equipment, and such repair or replacement shall be the
exclusive remedy of the purchaser, and in no case shall Branson be responsible for any
and/or all consequential punitive or incidental damages including without limitation, and/
or any consequential damages arising out of commercial losses.

WARNING General Warning

• Do not place parts or containers directly on the bottom of the tank; use a
tray or wire to suspend items. Direct placement can cause the units to fail

• Do not allow the solution to drop more than 3/8 inch (1 cm) below the
operating level line

• Do not ever use alcohol, gasoline or flammable solutions. Doing so could
cause a fire or explosion. Use only water-based solutions

• Do not use mineral acids. These could damage the tank

First time cleaning - First experiment with one piece, then proceed with the remainder.

100-214-294 REV. 05 5

CAUTION General Warning

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.

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.

2.1 How Ultrasonics Works

Ultrasonic sound is sound transmitted at frequencies generally beyond the r ange 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

8 100-214-294 REV. 05

2.2 Ultrasonic Baths

This line of ultrasonic baths include five sizes:

Table 2.1 Ultrasonic Baths Available

Model Number Tank Capacity

1800 1/2 gal. (1.91 l)
2800 3/4 gal. (2.81 l)
3800 1-1/2 gal. (5.71 l)
5800 2-1/2 gal. (9.51 l)
8800 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 1800 and 2800 have a molded dip in the
left side of their rims to facilitate emptying of solution from the tank. Models 3800, 5800
and 8800 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.

Temperature
Protection
(CPXH only)

The heater may cause some discoloration of the tank. This is normal
and will not affect the performance of the unit.

The fastest method to heat your ultrasonic bath is to fill with warm
solution, use heat, ultrasonics (which also adds heat), and a cover.

If Max Temperature of 75° C is reached, Ultrasonics will pause for a
period of time until the temperature in the bath falls back down to 69° C
(the max set point). Once the temperature falls back down to 69° C,
Ultrasonics will resume. This will apply for both continuous/infinity
mode, as well as timed mode. In timed mode, the timer will pause while
Ultrasonics is off, and will resume once Ultrasonics resumes.

4.4 Cleaning Solutions

CAUTION General Warning

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.

4.4.1 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.

Table 4.9 Alkaline Solution Strength and Uses

Alkaline Strength Removes

Mild Light oils and greases, cutting oils and coolant compounds.

Mild to Strong

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.

4.4.2 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.

Heavy grease and oils, waxes, vegetable oils, inks, wax or fat­base buffing and polishing compounds, milk residues and
carbohydrates.

22 100-214-294 REV. 05

4.4.3 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.

Harmful Chemicals

Acetophenone Chloracetic Acid Hydrocyanic Acid
Aluminum Chloride Chloric Acid Hydrofluoric Acid

can be used for cleaning process control or to verify the accuracy of the CPXH temperature
readings.

For CPXH models, wait 2 minutes after turning the unit on before taking
measurements. This allows for the display to be properly updated.

Suspend a thermocouple in the bath without allowing the probe to touch the
tank walls.

The amount of visible activity is not necessarily related to optimum
cavitation for cleaning.

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 mode is also used where gas has to be removed from
liquids or samples.

Heat Increases the chemical activity of cleaning solutions.

56 100-214-294 REV. 05

Never use solvents. Vapors of flammable solutions will collect under
the unit, where ignition is possible from electrical components.

It can be reduced by adding solution to the bath. Reduced surface
tension will increase cavitation intensity and enhance cleaning.

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.

6.6 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.

6.6.1 Direct Cleaning Method

Figure 6.6 Direct Cleaning 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

• Cleaning effectiveness

6.6.2 Indirect Cleaning Method

Figure 6.7 Indirect Cleaning Method

100-214-294 REV. 05 57

How it works:

• Fill the tank with warm water and a cleaning solution. The tank can be filled with any amount of
diluted solution as long as it reaches the water level line once the items to be cleaned and
accessories are placed into the tank

• 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
or 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

6.6.3 Non-Cleaning Application

This method can be used for sample preparation, which includes degassing liquids,
mixing, homogenization, dissolving solids, cell lysing and dispersion or particles.

Figure 6.8 Non Cleaning Application

How it works:

• Fill the tank with water and wetting agent. The tray or beakers can be filled with any amount of
solution as long as the water in the tank outside the tray or beakers reaches the water level line

• Place the beakers in a beaker positioning cover, an insert tray or an insert basket to fit your unit,
or place the beakers and flasks onto a Branson support rack. Beakers should not touch the tank’ s
bottom

Follow these recommendations to optimize your Ultrasonic Bath unit.

Table 7.1 Tanks

Covers

Check the tank for contamination whenever you change solution. If
necessary, remove contaminants with a nonabrasive cloth and water.

Always unplug the unit before emptying the tank. Empty the solution
into a waste disposal unit.

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.

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.

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 1 inch (2.5 cm) between the tank bottom and the
beaker or receptacle for adequate cavitation.

Allow the unit to heat up faster, to a higher temperature, and avoid
excessive liquid evaporation. Howev er, obstructing the cover vents will
cause the unit to overheat.

7.3 Glass Slide Test

Check your ultrasonic bath periodically to test the level of activity of the ultrasonic
cavitation. Frequency of testing will depend on your use of the unit, however, Branson
suggests running this test monthly.

You will need the following equipment:

• Frosted microscope glass slide (1” x 3”), such as Fisherbrand®1 #12-550-343 frosted
microscope slides, or equivalent;

• No. 2 lead pencil; and

• General purpose household cleaning solution, such as Dawn®

Test procedure:

1. Prepare a fresh solution with general purpose household cleaning solution (concentration 1%)
and warm tap water 49° C – 60° C (120° F – 140° F).

2. Fill the tank to within 3/8 inch (1 cm) of the “operating level” line.

3. Turn the ultrasonics on for at least five to ten minutes to allow for degassing.

4. Prepare the glass slide by first wetting the frosted portion with tap water.

2

liquid soap

Glass Slide

Penciled “X”

Frosted End

5. With the No. 2 pencil, on the frosted portion make an “X” from corner to corner.

6. Immerse the frosted end of the slide into the solution. Hold the slide vertically and center it in the
solution.

7. Make sure that model CPX/CPHX models are in Timed or Constant Sonics Mode, not Degas Mode,
then turn ultrasonics On.

The ultrasonics will begin immediately to remove the lead from the slide. All lead should
be removed within 10 seconds. If your unit passes this test, its ultrasonic cavitation is
acceptable.

NOTICE

To ensure consistency from test to test, be sure to repeat test
conditions—use the same solution concentration, liquid level,
temperature, type of pencil, length of degassing, etc.
