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.
