Safety Pre-Cautions
Before using your Ultrasonic Cleaner, please read and thoroughly understand
these warnings. Failure to follow them may result in serious personal injury of
property damage.
1. To avoid electrical shock
Only use the cleaner where there is a good grounding connection.
Unplug from power source before filling or emptying the tank.
Don’t disassemble your cleaner-high voltage inside the cleaner is
dangerous.
Don’t immerse the cleaner in water.
2.To avoid personal injury and property damage
Don’t use alcohol, gasoline or other flammable solvents to avoid explosion or
fire.
Cleaning trough or detergent may be hot, don’t touch with hand.
Don’t let the temperature of the cleaning liquid to go over 70°C.
3. Avoid damaging the facility
Don’t operate the cleaner dry.
Don’t use strong acid or alkali or other corrosive solution to avoid damaging
the cleaning trough.
Only water soluble detergent should be used.
The cleaner should not be started while there is no cleaning liquid in the
trough.
The water surface should not be lower than "MIN.LEVEL" to prevent damage to
heating device.
Don’t directly place the work piece on the bottom of the trough, it should be
suspended or placed on a support rack so as to avoid damaging energy
converter.
The cleaning liquid should be changed regularly; otherwise dirt deposits will
form at the bottom of the trough which may affect the cleaning results of
ultrasonic cleaning. Moreover, many types of detergent lose potency in time;
therefore detergent should be added periodically.

Method of Cleaning
Ultrasonic sound is sound transmitted at frequencies generally beyond the range of
human hearing. In your ultrasonic cleaner, ultrasonic sound (sonics) is used for
cleaning materials and parts.
Direct cleaning (refer to figure 1)
Place water and detergent in the cleaning trough, then place work piece on the
support rack, Lower them into the trough or suspend the work piece then lower them
into the liquid.
Indirect cleaning (refer to figure 2)
Place water and detergent into the cleaning trough, and put all the chemicals into a
beaker or other suitable container and then put the work piece into the liquid. Now put
the container of the chemical detergent and work piece into the trough.
Caution: do not let the container touch the bottom of the trough.
The direct and indirect cleaning methods both have advantages and disadvantages. If
you are not sure which one to choose please carry out tests first before making a
choice. The advantage of the direct cleaning method is that the cleaning is very
efficient and easy to operate. The indirect cleaning also has advantages, which are
that the dirt being cleaned off can be clearly seen in the beaker or the container, and
then it can be filtered out or disposed of. Also at the same time we can use two or
more than two types of cleaning solvents.

Application Hints
1. Choose the cleaning method:
Direct cleaning: place the support rack, water, detergent, and work piece into the
trough, or suspend the work piece in a bracket and submerge them into the
cleaning liquid. It is strictly prohibited to put alcohol, propylene, gasoline or other
flammable solvent, or strong acid or alkali, or other corrosive liquid into the trough.
If the above mentioned solvent is necessary then we recommend the use of indirect
cleaning method.
Indirect cleaning: put water and detergent into trough, put all necessary chemicals
into the beaker or other proper container, and submerge them into the cleaning
liquid. Then put all the chemical detergent and work piece into the trough.
2. The cleaner is powered by connecting the mains plug to a standard socket-outlet,
always place the cleaner in such a way that it is easy for the operator to unplug the
mains plug in emergency.
3. Position your cleaner within easy reach of a standard grounded electrical outlet. Do
not place the cleaner on a circuit which could become overloaded.
4. These cleaners are NOT floor standing equipment. Always use the cleaners on
tables, work benches, and other similar surfaces.
5. Always use the cleaners in an environment of good ventilation. Special care should
be taken not to block the bottom fan vent of the relevant models.
6. Please always keep the liquid level between the "MAX.LEVEL ”and “MIN.LEVEL”.
7. Adjust the timing to proper time. Work piece of different types require different
cleaning times. Most of them only need about a few minutes while others might
take a bit longer. The details can be decided via testing.
8. It is faster and more efficient to run several small loads rather than few big loads.
9.Turn power on,wait 10 minutes to let the cleaner liquid to purge the gas, the process
of which is only required at the beginning of every day cleaning or after the change
of solvent.
10. When you first fill your unit, or refill it with fresh solution, use warm water for the
solution. Turn on the heater (press the HEAT switch, if available), turn on the
ultrasonics (press the SONICS), add the cover and the solution will heat quickly to
temperature.
11. Rinse, drying and lubrication:
Rinse the parts to remove the chemicals which adhere to the parts after cleaning.
Dry the parts with clean compressed air, hot air blower or in an oven.
Relubricate parts that need lubrication.
Please call VWR if you have application questions.

Cleaning Solutions
WARNING
Do not use corrosive solutions, such as bleaches, strong acids or powerful caustics, 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 contaminates.
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 contaminate from redepositing on the cleaned surface, and improves cleaning
action in hard water.
Change the cleaning solution periodically. Cleaning solutions can become
contaminated with suspended contaminate particles which coat the tank bottom. This
coating dampens the ultrasonic action and reduces cleaning efficiency. Certain
solutions will cavitate better than others. Contact VWR 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 contaminates.
Solution amounts: solution amounts may vary. The amount you use depends on the
detergent and the type of contaminate to be removed. Follow instructions on the
solution container and refer to the table below for the effects of solutions on metals.
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.

Optimizing Your Cleaner
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 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 (1 inch from the top with beaker/support rack 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 support rack and/or beaker positioning cover to support all items. Allow at
least 1 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.
Shell:
Cleaning-the ultrasonic cleaner may be cleaned using a dry soft towel. Do not use
liquids to clean.
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 - a cleaner with heater and with a cover will stabilize at 70°C approx,
running continuously. Ultrasonics will add heat to the solution.
Solution:
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, using
Degas mode speeds up the degassing process. 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 a wetting agent of surfactant to the bath.
Reduced surface tension will increase cavitation.
8

Optimizing Your Cleaner
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, become spent over time. Solutions can become
contaminated with suspended contaminate particles which coat the tank bottom,
inhibiting ultrasonic activity.

Operating Your Cleaner with Ultrasonic & Heating Feature
4. If the unit is turned off when it is in operation and the power is not removed, it will
restore the status and setup of the last operation when it is turned on again.
5. Turn on the power and start heating at ultrasonic standby status (ultrasonic is not
turned on), the machine will activate ultrasonic device for 5 seconds every 2
minutes to balance solution temperature. The function is not available at degassing
standby status.
6. When ultrasonic or degassing finishes, heating stops simultaneously and the machine
turns to standby status. To maintain the temperature, simply turn on the machine
and then turn on HEAT key. The machine will restore the set temperature of the last
operation and go to heating status.
NOTE:
You may require an exact/constant temperature for your application. Please note that
ultrasonics may continue to heat the solution beyond your set temperature, even
though the heater has cycled off and the “Heat On”light is still light. If this happens,
turn the cleaner off and allow the solution to cool down. For a fast cool down, replace
some of the warm solution with cold solution.
The optimal temperature of the heating solution is 55 ~ 60°C. When the temperature
goes up to 65 ~ 80°C, ultrasonic internal resistance would increase by 10~20%and
the power would reduce by 24~34%
Before you start cleaning: WARNING
Don’t place parts or containers directly on the bottom of the cleaning tank; use a
support rack, wire or beaker cover to suspend items.
The water surface should not be lower than “MIN.LEVEL”to prevent damages to
heating device.
Don’t ever use alcohol, gasoline or flammable solution. Doing so could cause a fire
or explosion. Use only water-based solutions.
Don’t ever use mineral acids or bleaches. These could damage the tank.
Step
1. Select your cleaning solution.
2. Allowing for the volume of the parts you will be cleaning and cleaning solution, fill
the tank with warm tap water to the operating level line.
3. Add cleaning solution to the tank water.
5. Plug the cleaner into a grounded outlet.
