1. Safety Warnings
CAUTION! Read carefully before use:
This ultrasonic cleaning device is designed exclusively for the acoustic
irradiation of objects and liquids.
Check the housing, the operating elements and the transducer tank for possible
shipping damage before connecting the unit to the power supply. In case of any
shipping damage do not connect the unit to the mains. Contact your supplier and
forwarder.
Put the unit on a dry and solid surface.
Check for correct voltage; the voltage required is indicated on the nameplate on
the back of the unit.
The unit must be connected to an earthed socket only. Keep the work surface
and the operating elements clean and dry to prevent accidents caused by
electricity.
Fill the ultrasonic cleaning bath with liquid up to approx. 2/3 of its volume before
use. Do not operate the unit without liquid.
If the unit is operated over longer periods check the filling level regularly. Any
operation of the ultrasonic unit without liquid might cause damage to the
transducer system.
Please note that so-called "start-up splashes" can occur. When the filled unit is
started, some of the liquid can splash out.
The tank of a unit with heating, can heat up while operating
Do not touch the tank inside when the heating is on. Risk of burning!
Do not reach into the tank during the ultrasonic operation.
For your information: Cell membranes could get damaged by extended exposure
to ultrasound.
Pull the mains plug before emptying the unit (by pouring out the liquid).
Please do not immerse the device in water under any circumstances. This would
create a serious safety hazard for the user. Resulting injury to the person and/or
damage to the electronics of the device cannot be excluded.
Warning in respect of inflammable liquids:
Under no circumstances may inflammable liquids, e.g. solvents, be used
directly in the ultrasonic cleaning tank. There is a risk of fire and explosion!
For your information: The ultralsonics increase the evaporation of the liquids and
form a fine mist which could ignite at any time through contact to a source of
ignition.
Materials which present a risk of explosion and inflammable solvents
-in the risk groups according to VbF (fire regulations) AI, B, AII, AIII
or marked with symbols and danger warnings in accordance with the EC
regulations - E or R 1, R 2 or R 3 for combustible materials or
- F+, F or R 10, R 11 or R 12 for inflammable materials
may not be placed in the stainless steel tank of the ultrasonic device.
3

Only the ultrasonic devices which are specially marked with the symbols Al, All or
Alll have been approved in accordance with VbF for correspondingly inflammable
solvents of the same or a less dangerous risk groups.
Limited volumes of inflammable liquids, as defined in the general industrial safety
regulations, can be acoustically irradiated with the assistance of the ultrasonic
device under following conditions: If they are placed by sufficient external
ventilation in an appropriate separate container (example beaker glass). This can
get immersed into the stainless steel tank, which has been filled with non-
inflammable liquid (water with a few droplets of interlacing agent).
Warning in respect of aqueous cleaning agents:
Do not use aqueous cleaning mediums directly in the ultrasonic vat which are in
the acidity range (pH value lower than 7), to which fluoride (F-), chloride (Cl-) or
bromide
(Br-) ions will be introduced with the contamination of the parts or with the cleaning
agent. These will destroy the stainless steel tank during ultrasonic operation in a
very short time as a result of pitting corrosion.
Other agents which have a corrosive effect when used in high concentrations
and/or at high temperatures during ultrasonic operation are, e.g. nitric acid,
sulphuric acid, formic acid, hydrofluoric acid (even when diluted), potassium
hydroxide solution (leads to stress corrosion cracking in the ultrasonic tank). This
list is not necessarily conclusive.
The restrictions on the use of the ultrasonic tank listed above also apply when the
chemical compounds cited above are introduced to the tank which is filled with an
aqueous medium (in particular also for distilled water) as contamination or in the
form of carry-over.
In addition, this restriction also applies to customary cleaning agents and
disinfectants, should they contain the compounds mentioned above.
Be certain to also heed the safety precautions provided by the manufacturer of the
chemicals (e.g. glasses, gloves, caution and safety tips).
We, therefore, recommend that you use the cleaning agent specially adapted for
use in the ultrasonic bath developed and manufactured by ELMA. (Page 9,
Cleaning Agents. Areas of Use)
Maintenance and repairs
Any repair, maintenance or alignment works on the connected and opened
unit must be carried out by authorised personnel only.
Pull the mains plug before opening the unit for any repair and alignment works.
Any faulty parts must be replaced by original spares only in order to keep in
compliance with the strict safety regulations.
Please consult the manufacturer regarding any damage claims.

2. Operation
Fill the unit with liquid before connecting it to the power supply. If you use water
as contact medium we recommend the use of the suitable ELMA Clean cleaning
solution to be added to the water. The ELMA Clean chemicals contain tensides
that reduce the surface tension and are specially designed for the use in an
ultrasonic bath. Switch on the ultrasonic unit and let the liquid degas for a few
minutes. Degassed liquids allow better cavitation. Furthermore, special degas-
improving substances contained in the ELMA Clean chemicals accelerate the
cavitation process. The use of the cleaning chemicals guarantee a long service
life of the TRANSSONIC ultrasonic unit.
The optimum temperature for your specific cleaning task is indicated on the
label of the used ELMA Clean solution along with the mixing concentration and
the recommended cleaning time.
If you use pulverised or granulated cleaning media by other suppliers ensure
that the pulver or granulates dissolve completely. Any residue and particles on
the tank floor may cause contact corrosion and create pinholes in the material.
The items to be cleaned must be covered completely by the cleaning liquid. We
recommend to put the items in/on a holder basket to protect the stainless-steel
tank. Do not put the items directly on the tank floor. These measures
considerably prolong the service life of the stainless-steel tanks.
If you use aggressive chemicals (e.g. acids, alkalines) we recommend the use
of plastic tubs (acid-resistant tubs; see Elma catalogue Accessories).

a) Switch On/Off
You switch on the ultrasonic unit by setting the timer or turning the timer
knob to the infinity position.
The green lamp (not available on all units) indicates the operation of the
unit.

b) Setting of the timer
Timer
For cleaning periods of up to 15 minutes use the timer with automatic
switch-off. The required cleaning period is set by turning the knob. After the
set period the ultrasound is switched off automatically. If you need to switch
off the unit before the set period is over turn the timer knob back to the OFF
position.
Permanent Operation
If you require a cleaning period longer than 15 minutes turn the knob to the
infinity position. In this operation mode the unit has to be switched off by
hand.
c) Heating
The heating is switched on and off by the green button (fig. 1). Ensure that
the filling level in the tank is correct before switching on the heating. This
prevents overheating of the tank at the spot where the heating is fixed.
Please note that the liquid will heat up by ultrasonic activity alone without
heating. This effect is even stronger when a cover is used.
Heating and ultrasound can be operated separately. Higher temperatures
usually shorten the cleaning period considerably.
As ultrasonic activity additionally heats up the cleaning liquid do not set the
temperature too high when operating the unit over longer periods.

a) Switch On/Off
Switch on the unit by turning the knob (1) clockwise. Switch it off by turning
the knob anti-clockwise to the 0 position.
b) Setting of the Timer for Ultrasound
Set the required time by turning the knob (1). When the unit is switched on it
works in long-term mode. You can choose periods between 2 and 95
minutes or set the unit to infinity operation (position mode).
When the unit is switched to infinity operation mode, the indicator (2) shows
„00“ or „0.0“. After turning the knob (1) clockwise until it stops at the ãmodeÒ
position, the unit switches automatically to the short-term mode. By turning
back the knob you can now set a period between 0.2 and 9.5 minutes.
Turning the knob again to the ãModeÒ position puts the unit back into the
long-term mode.
c) Ultrasonic Power Regulation
The buttons „-„ (3) and „+“ (4) regulate the required cleaning power.
When the unit is switched on the power is set and indicated (5) at 100 %.
d) Temperature regulation
The knob (6) switches on heating regulation and temperature indicator (7).
The indicator (7) always shows the actual temperature in the cleaning bath.
Turn the knob clockwise and set the required temperature (scale).
If the required temperature (scale) is higher than the actual temperature
(indicator 7) the cleaning liquid will be heated up. During the heating up
period the right decimal point of the indicator (7) flashes. As soon as the
required temperature is reached the decimal point stops flashing and the
heating switches off.
ATTENTION: The temperature indication may deviate from the actual
temperature by up to +/- 2¡C. Note that the ultrasonic activity creates heat
which may cause the temperature to rise above the set value. Low
temperatures cannot be kept with permanent ultrasonic activity.
e) Degas
The Degas device is activated by the button (9).
When the Degas function is switched on the green indicator flashes and
the cleaning liquid is degassed very quickly. This process increases the
cleaning effect of the medium and shortens the overall cleaning period. The
Degas device is particularly useful when the bath has been newly filled. In
addition, the Degas function allows various applications in the sono-
chemical sector, e.g. degassing of high-polymer solvents.
7

f) Start/Stop
The ultrasound is switched on by the button Start/Stop (8); the indicator
flashes. When the ultrasound is switched on the set cleaning period starts
and the remaining cleaning period is constantly indicated. Pressing the
button again stops the ultrasound. The remaining cleaning period is still
indicated and continues to run down when the Start/Stop button (8) is
pressed again.
When the set cleaning period is over the ultrasound is automatically
switched off and the indicator (2) shows the originally set period.
If you want to set the cleaning period back to its original value during
operation you do not need to turn the knob (1) again. Just press the
Start/Stop button (8) and keep it pressed for 3 seconds.
g) Special Features
All settings can be changed during ultrasonic operation.
Period: Set the new required period by means of knob (1). Ultrasound
and temperature indicator stop for 2 seconds. Then the unit
starts operating again for the newly set period.
Power: Set the new power by pressing the buttons „-„ (3) or „+“(4).
Heating: The set temperature can be changed during ultrasonic
operation.
Degas: The Degas function can be switched on and off during
ultrasonic operation.

a.) Switch On/Off
You switch on the ultrasonic unit by setting the timer or turning the timer
knob to the infinity position.
The green lamp (not available on all units) indicates the operation of the
unit.
b) Setting of the timer
For cleaning periods of up to 15 minutes use the timer with automatic
switch-off. The required cleaning period is set by turning the knob. After the
set period the ultrasound is switched off automatically. If you need to switch
off the unit before the set period is over turn the timer knob back to the OFF
position.
Permanent Operation
If you require a cleaning period longer than 15 minutes turn the knob to the
infinity position. In this operation mode the unit has to be switched off by
hand.
c.) Power regulation
The ultrasonic power is variable from 10 to 100% and is regulated by knob (2).
Turning the knob clockwise increases the power. The power is automatically
kept at the set level.
d.) Operation modes
You can choose between the operation modes sweep, standard and degas by
means of knob (3).
Sweep: The frequency varies permanently within a defined range. This shifts
the minima and maxima of the sound field within the bath. It also allows a more
even load of the ultrasound transformer. The cleaning effect is more
homogeneously distributed in the bath than during standard operation.
Standard:The frequency is regulated against the mechanical resonance of the
ultrasound transformer. This optimises the performance in the distributed
maxima.
Degas: The set power is interrupted for a short period so that the bubbles are
not retained by the ultrasonic forces. The degassing effect is stronger with high
ultrasonic frequencies than with lower frequencies due to the directional
diffusion. We recommend this operation mode particularly for newly filled baths.
The operation modes can be changed during operation.
e.) Setting of frequency
On multi-frequency units you can choose between a low and a high ultrasonic
frequency by means of knob (4). When the knob is in neutral position 0, the
ultrasonic activity is switched off. The frequency can be changed during
operation.

f.) Heating
The heating is switched on and off by means of push button (8). Set the
required temperature by turning knob (7). The scale indicates the temperature
in centigrade. As soon as the set temperature is reached the control lamp (6)
switches off.

g.) Surface skimming (optional, TI-H-25 and larger)
Using the supply duct (9) and the discharge of the overflow device (13) a
current on the surface of the bath can be created. This allows the skimming of
floating particles (e.g. oil).
h.) Floor scouring (optional, TI-H-25 and larger)
Particles settling on the tank floor can be washed away by means of the
scouring function. For this connect both supply (10) and discharge (11) to the
external pumping/filtering unit.
i.) Remote control (optional, TI-H-25 and larger)
The ultrasound unit can be operated by remote control from a central control
unit. The remote control is connected to socket (14).
j.) Filling level control (optional, Tl-H-25 and larger)
The filling level control switches off heating and ultrasound as soon as the level
falls below a certain limit. Approx. 5 seconds after refilling the tank heating and
ultrasound are switched on again.

6. General
The ultrasonic cleaning process:
The ultrasonic transducers mounted under the tank floor turn electric energy into
mechanic vibrations. The cleaning liquid in the stainless-steel tank starts
vibrating, too. During this process, tiny vacuum bubbles are produced that
implode. This is called cavitation. The cavitation removes dirt from every spot that
the cleaning liquid reaches.
7. Cleaning chemicals / Application
The cleaning chemical to be used must be suitable for the use in an ultrasonic
bath to prevent damage to the transducer tank. Do not use flammable products
(see chapter Safety Warnings). Do not use chemicals containing halogenide
ions or salt as they may cause pitting corosion in the tank. Acids such as
hydrochloric acid, sulphuric acid or nitric acid destroy the unit in very short time.
In particular acid cleaners (e.g. for derusting or the removal of mineral dirt such
as lime) must be used only when specially designed for this purpose.
We offer our own range of ELMA cleaning chemicals specially developed and
made for the use in ultrasonic cleaners which guarantees a long service life of
our ultrasonic baths. The following table shows the most frequently used of our
ELMA chemicals. If you use cleaning chemicals by other suppliers observe the
instructions given on the label, in particular the instructions concerning the use
in ultrasonic baths. Contact your supplier for these cleaning chemicals.

Notes on the Cleaning of Items:
- Place the items to be cleaned in a basket.
- Put the dirtiest items lowest.
- Do not place the items one on another as this will absorb the ultrasound.
- Sensitive items such as chirurgical instruments should not come into
contact with each other. We recommend the use of silicon mats available
from your supplier. These prevent the direct contact among the single
items.
Attention! The cleaning liquid heats up during prolonged ultrasonic
operation.
Take this into consideration when cleaning temperature-sensitive items.
8. Maintenance
The following measures will considerably prolong the service life of your
ultrasonic bath. We recommend removal of the cleaning liquid and any residues
from the tank after use. Wipe the tank clean.
Clean the tank carefully and remove all residues such as small metal particles
or any other kind of dirt before changing the cleaning liquid. Small particles in the
ultrasonic tank will eventually destroy the stainless-steel tank.
Do not place the items to be cleaned on the tank floor. Use a rack or a cleaning
basket (see paragraph Notes on the Cleaning of Items).
Do not use any scraping tools. A plain and clean metallic surface prolongs the
service life of the ultrasonic tank. Should there be any lime deposits fill the tank
with ELMA Clean 60 or ELMA Clean 115 in the recommended concentration and
operate the unit for approx. 1 minute to improve the cleaning effect. Then empty
the bath and wipe it out.
If neither ELMA Clean 60 nor ELMA Clean 115 is at hand use any lime remover on
phosphoric acid base. The use of such a lime remover is possible as long as it
does not contain any chloride ions.
We recommend the use of chemicals specially designed for application in a
TRANSSONIC ultrasonic bath.
