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.

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).
