Product Description

Ultrasonic and rinsing bath, type SONOREX TECHNIK RM .The exact type speciﬁ cation and serial number are found on the type plate, on the rear side of the ultrasonic bath.

Product features:

Stainless steel oscillating tank (1) with transducers, ultrasound frequency 40 kHz
Easy-to-clean stainless steel housing (2)
Filling level mark for safe ﬁ lling (3)
Weir/overﬂ ow (4) with ball valve to produce a liquid circuit.
Legs (5) for a secure position
Outlet with 3-way ball valve (6) for easy draining/ﬁlling of the bath ﬂ uid
Depending on the model, with time switch (type “U”) for 1 – 15 min or continuous operation (7) and/or with heating (type “H”) (8).

Mode of operation

SONOREX ultrasonic baths use the eﬀ ect of cavitation. Under their oscillating tank bottoms they contain piezoelectric transducers, the energy of which is transferred to the bath liquid with ultrasound frequency as mechanical oscillations. As a result, microscopically small bubbles are continuously formed in the bath liquid, which release energy upon imploding and generate local microcurrents. This process is called cavitation. During the cleaning process, it causes contamination to be “blasted” from the hard surfaces of the objects being treated. At the same time, dirt particles are removed and fresh bath liquid ﬂ ows in. During sonochemical processes, cavitation may have a catalytic eﬀ ect, e.g. with the production of stable emulsions or the rapid degasiﬁ cation of ﬂ uids with a high gas content.

Purpose

SONOREX TECHNIK ultrasonic baths are intended for the sonication of aqueous liquids. They work on the basis of low-frequency ultrasound and can be used in versatile ways. Their main application is the gentle and intensive cleaning of objects of diverse shapes, types and sizes. Sonication is always carried out together with a suitable preparation that is added to the bath ﬂ uid. In order to use the device as intended, a basket or other inset beaker is required, into which objects are placed during sonication. An optimum diﬀ usion of the ultrasound can only be guaranteed in this manner. The unit is operated from the front. The SONOREX TECHNIK ultrasonic bath is usually operated with the unit placed on a table.

Warnings and safety precautions

General

Keep the ultrasonic/rinsing bath out of the reach of children and of persons who have not been instructed in its operation by reference to these instructions.
We do not guarantee against damage to the ultrasonic/rinsing bath or oscillating tank, or to the objects to be treated, as a result of use of inadequate disinfection agents or detergents.
Keep the surface of the ultrasonic/rinsing bath and operating elements clean and dry.
Do not expose the ultrasonic/rinsing bath to corroding inﬂ uences.
Only move the ultrasonic/rinsing bath when it is empty.
Empty the ultrasonic/rinsing bath only while turned oﬀ .
The tank is emptied with no peripheral devices connected, using the three-way ball valve. To do so, turn the handle in the direction of the outlet.
Ultrasonic baths adhere to prescribed EMC limit values, such that it can be assumed that the electromagnetic radiation emanating from the units is harmless to humans. A binding statement for wearers of implants can only be made at the place of work and together with the implant manufacturer. In case of doubt, information regarding the allowable electromagnetic exposure level is to be obtained from the implant manufacturer.
If the unit is passed on to others, the operating instructions with the safety instructions must also be handed over.

Operation and transport

Observe ambient and set-up conditions, see Chapter 1.4.
Only plug in the ultrasonic/rinsing bath to an outlet with a grounded socket.
Do not operate the ultrasonic/rinsing bath without ﬂuids.
Do not stand or lay any objects on the tank bottom, accessories must be used, see Chapter 7.
Do not immerse any parts of the body (e.g. hands, feet) or living beings (animals or plants) in the tank; in particular, do not immerse them in the ultrasonic ﬂ uid during ultrasound operation. Danger: Ultrasound has a cell-destroying eﬀect.
In the event of continuous activity within a 5 m radius, adequate hearing protection must be used. Danger: Hearing loss is possible if not wearing hearing protection during operation – the typical ultrasound cavitation noise can be perceived as very unpleasant.
When preheating the bath liquid, stir at least every 30 min. or switch on the ultrasound. Danger: Scalding due to retardation of boiling.
Do not leave the ultrasonic/rinsing bath unattended while in operation.

Damages and defects

If damage to the ultrasonic/rinsing bath is detected, do not connect the ultrasonic/rinsing bath to the mains.
In the event of defects, disconnect the power plug immediately.
Repairs must only be conducted by authorized skilled personnel or by the manufacturer.
Defective parts may only be replaced with original SONOREX parts.

Preparation

Carefully unpack the ultrasonic/rinsing bath and accessories and inspect them for completeness or possible transportation damages. If any damages or defects are found, these must be immediately notiﬁ ed in writing to the transportation company and to the supplier. Before startup, the ultrasonic bath is to be left to stand at its operating location for 2 hours so that it may adapt to the ambient conditions.

Scope of delivery

1 Ultrasonic/rising bath, see delivery note
1 Accessories kit
1 User instructions
Additional accessories according to order – see delivery note

Set-up / assembly

Place the ultrasonic/rinsing bath on a ﬁ rm, level and dry surface. In doing so
- observe the maximum weight of the tank, including liquids. For net weight, see technical data, chapters 1.4.1 to 1.4.3.
- do not block the air supply below the tank.
- guard against moisture and wetness – risk of electric shock.

Set-up

Fully remove transportation aids (pallets, transport safety devices).
Set up the ultrasonic/rinsing bath in a dry room.
Mount the separately packaged ball valves for each tank as follows:

Screw the counter nut onto the threaded sleeves 1 at the tank outlet (3-way ball valve) and tank overﬂ ow (ball valve), then seal with the white PTFE tape provided, applying several turns of tape to the right.
Tape the hose socket threads 2 with PTFE sealing tape.
Screw the hose sockets 2 into the ball valve outlets 3, use the appropriate spanner.
Screw the ball valve 3 onto the threaded sleeves and tighten with the counter nut 4.
Caution: Do not screw the ball valve up to the limit stop or back it oﬀ by rotating it slightly to the left, this will cause the PTFE tape to lose its sealing eﬀect.
Close the ball valve, turn lever 5 upwards.

Start-up

Thoroughly rinse the ultrasonic or rinsing bath’s oscillating tank with water before its ﬁrst use.
Verify that the control buttons are in the “oﬀ ” position, i.e. the switch indicator is at the top, then connect the bath to the mains.
Conduct a function test on the ultrasonic bath – brieﬂ y plug in the ultrasound (maximum of 1 to 2 seconds), a hissing noise should be heard. Set to “0” once again.
Hang accessories in the ultrasonic bath and place lid on top.
Connect peripheral devices if required – see additional documentation.

Operation

Operating elements

The ultrasound and the heating system are operated from the front:

Turning knob for Heating ON / OFF incl. adjustment control
Turning knob for Ultrasound ON / OFF with preset time
White control light (Heating is activated)
Yellow control light (Heating in operation)
Green control light (Ultrasound in operation)

The layout of the turning knobs depends on the bath.

Ultrasound

The ultrasound is operated through the turning knob (time switch).

Timed operation

Turn the knob to the right
- range of time 1 – 15 minutes
- Green control light is illuminated.
- Once the time has elapsed, the time switch automatically turns oﬀ.
By turning the knob back, the operating time is shortened or the ultrasonic bath is turned oﬀ.

Continuous operation

Turn knob to the left
- Setting ∞
- The green control light is illuminated.
- The ultrasonic bath does not turn oﬀ automatically; to switch it oﬀ turn the knob to the right, back to “0”.

Notes

Even while turned oﬀ, the ultrasonic bath may remain connected to the mains. It can be disconnected by pulling out the mains plug.
An “engaging” of the time switch is barely felt if the mains voltage is not present, e.g. if the mains plug is disconnected or the fuse is blown. The time switch only works if the mains voltage is present.

Heating

The heating is operated through the turning knob (heating).

Turn knob to the right
- Temperature range 30-80 °C:
- The yellow and white control lights are illuminated.
- The yellow control light goes out when the set temperature is reached.
- To turn it oﬀ, turn the knob left back to “°C”.

Notes

The heating system works independently from the ultrasound.
The heating automatically turns on every time that the bath temperature drops below the set temperature.

Use

Sonication or rinsing always take place directly in the tank. For this purpose, the objects are placed in a basket and hung inside the tank which is ﬁlled with bath ﬂ uid.

Instructions for use

Instructions – ﬁlling

Check that all ball valves are closed.
Ultrasound and heating must be turned oﬀ .
Do not ﬁ ll ultrasonic tank with hot water. Maximum ﬁ lling temperature: 50 °C.
At least drinking-quality water must be used to ﬁ ll the oscillating tank.
Water without additives is not suited for sonication. BANDELIN recommends the TICKOPUR or STAMMOPUR preparations.
The ﬁ ll level must always be at or slightly above the ﬁ lling level mark.
A low ﬁ ll level will damage the ultrasonic bath!
This may happen when used for extended periods, for example as a result of evaporation. In such cases, the ultrasound and possibly the heating must be switched oﬀ (controller on 0). Once the tank is ﬁ lled up, the ultrasound and the heating, if applicable, can be switched back on.
When using with a liquid circuit (with FA, OX, WA or cascade pipes) the additional ﬁ ll volume of the peripheral devices must be taken into account:
Fill the ultrasonic bath with water and cleaning concentrate (in the appropriate dose!) up to the weir’s toothed edge ⇒ Follow the dosing instructions for the concentrate used. Also ﬁ ll all additional tanks up to the weir with municipal or DI water.
Do not use any combustible, explosive, non-aqueous liquids or azeotropic mixtures directly in the stainless steel oscillating tank (e.g. benzine, solvents). Furthermore, chemicals that contain or that separate chloride ions (some disinfectants, household cleaners, and dish detergents), may not be used directly in the stainless steel tank.
When using strongly acidic preparations, the hard chromium plating of the ball valve may become corroded and the ball valve start to leak. If the use of a strongly acidic cleaning agent cannot be avoided, the use of a stainless steel ball valve is recommended.
When using preparations, the safety instructions included in the product leaﬂ ets must strictly be adhered to.
Replace used sonication ﬂ uids, do not refresh by adding ﬂuids.

Notes – Inserting objects

Fully remove air bubbles from cavities (e.g. blind holes).

BANDELIN-RM-16.2-UH-Electronic-GmbH-FIG-9

Notes – Temperature and heating

Heated ﬂ uids intensify the ultrasound eﬀ ect. Experience has shown that the best results are obtained with a bath temperature of 50 to 60 °C. At higher temperatures, the eﬀ ect of the ultrasound cavitation decreases again, however/1.
In order to save time during use, the bath ﬂ uid may be preheated during degassing.
Ultrasound energy warms up the sonication ﬂ uid (even without additional heating).
- In case of continuous sonication and/or covering the oscillating tank, the ﬂuid temperature will increase, even rising above the value set on the thermostat. For this reason, check the temperature when treating temperature sensitive components.
- Non-aqueous ﬂ uids can heat up many times faster than water. A possible
  ﬂashpoint can be reached and/or exceeded after a very short sonication time. In the case of high-boiling liquids (with and without a ﬂ cashpoint), the bath temperature can increase to >120 °C due to the energy input of the ultrasound. This leads to irreparable damage to the ultrasonic bath.
For an optimum bath temperature, observe the speciﬁ cations from the preparation manufacturer!
To protect the electronic components inside the ultrasonic bath, the ultrasound output is reduced upon reaching a critical temperature to inhibit a further increase in the interior temperature.
The ﬂ uid in the oscillating tank may not exceed a maximum operating temperature of 100 °C.
Cover the ultrasonic bath when in continuous operation so that not too much bath liquid evaporates.
For safety reasons, ultrasonic cleaning baths and rinsing baths should be covered when not in operation, to prevent operating and external personnel from inadvertently coming into contact with the bath liquid or being injured by liquids that are still hot.

General use

Step 1: Fill the oscillating tank
The oscillating tank is ﬁlled with water and suitable preparation to reduce the surface tension, see chapter 7.3.

Fill 1/3 of the oscillating tank with water.
Add dosed preparation to the oscillating tank.
Fill carefully up to the ﬁ lling level mark, and avoid the formation of foam as much as possible.

Step 2: Degassing the fluid
Freshly filled bath fluid or fluid that has remained in the oscillating tank for a longer period must be degassed before use. See also chapter 4.3.1.

Remove the basket and other accessories from the oscillating tank.
Place lid on top.
Turn on the ultrasound with the turning knob and sonicate for 30 min for degassing, see chapter 3.1.1.

Step 3: Preheat fluid
In ultrasonic baths with integral heating, the fluid may be preheated independently of the ultrasound. This increases the ultrasound effect, especially when removing fats, oils, and polishing paste residue, and shortens the duration of the subsequent ultrasound.

Remove the basket and other accessories from the oscillating tank.
Place lid on top.
Using the turning knob, set the desired temperature, see Chapter 3.1.2.
For an even warming of fluids, stir the fluids or switch on the ultrasound for a few minutes now and then, otherwise, there will be a retardation of boiling – risk of scalding!

Step 4: Insert objects to be treated
Before every sonication, it is necessary to check whether the sonication fluid needs to be cleaned or replaced.

Hang the insert basket with the items to be sonicated.
Check that the objects to be treated are fully covered with fluid.
With every object inserted, the fill level is to be controlled.

For cleaning tasks
Place the objects to be cleaned in the appropriate accessories, in doing so please note:

Evenly distribute parts, do not stack them.
Overloading the basket will reduce the ultrasound effect (the ultrasound is absorbed).
Place the more heavily soiled side facing downward.
Parts with joints are to be fully opened before placing inside.
Fragile parts may not touch each other.
Due to the design, the ultrasound effect is weaker on the outlet side. Heavily contaminated objects should not be placed in the basket over the outlet.

Ultrasound – Operation
Fundamentally, the sonication time is to be as short as possible to protect the objects to be treated and the oscillating tank. In the case of stubborn residue, conduct sonication for a longer time if necessary.

Place lid on top.
Using the turning knob, set the desired sonication time, see Chapter 3.1.1.

Step 6: Remove treated objects
After sonication, the objects are to be removed from the ultrasonic bath. Allowing them to remain any longer in the bath fluid may damage them.

Switch off the ultrasound.
Remove the basket from the tank and place it securely on a horizontal surface. Depending upon the set temperature or the duration of sonication, the baskets and objects may be hot!
After the cleaning processes, rinse the treated objects with water of at least drinking quality. Visually review the sonication results.
Before the next sonication, verify the service life (see Chapter 4.3.2) of the bath fluid. Heed the specifications of the preparation manufacturer. If necessary, empty the oscillating tank.

Step 7: Empty the oscillating tank.
Layers of contamination on the tank bottom reduce the ultrasonic output. The oscillating tank is to be emptied after a long period of use or sonication of heavily soiled objects, see Chapter 4.3.2.

Switch off the ultrasound.
Empty the oscillating tank by pointing the 3-way ball valve handle in the direction of the outlet to open it.
After emptying the oscillating tank, thoroughly rinse it. Wipe dry with a soft cloth. For additional care instructions, see Chapter 5.

Further information

Degassing
Degassing the sonication fluid increases the ultrasound effect. Freshly filled-in fluid or fluid that has remained in the oscillating tank for a longer period must be degassed before use. Gases dissolved in the fluid (e.g. oxygen) are reduced through degassing and the ultrasound effect is thus significantly improved. The cavitation noise changes during degassing, loud degassing noises disappear at the end of the degassing process and the ultrasonic bath appears to work more quietly. A lower noise level, however, does not mean a reduction in ultrasonic power. It rather means the end of the degassing process and an improvement in the ultrasound effect.

Disposal of sonication fluids
The working solution is disposed of under the specifications in the product leaflet and the label supplied by the manufacturer of the preparations employed. All aqueous preparations made by DR H. STAMM GmbH are prepared under the regulations of the German Washing and Cleansing Agents Act, are biodegradable, and as working solutions may be disposed of in the wastewater. Strongly acidic and strongly alkalinefluids are to be previously neutralized under technical data sheet specifications. The manufacturer’s specifications for the respective preparations should be observed. During cleaning, materials hazardous to water such as oils, heavy metal compounds, etc., depending on the type of contamination, may enter the working solution. If the limit values are exceeded, the working solution must be reconditioned (removal of contaminants) or disposed of as toxic waste. Disinfection and cleaning agents that become contaminated when used are considered “waste material” under the German Waste Act (AbfG) and may not be taken back by the manufacturer. In other countries, the relevant supplementary/divergent national regulations should be taken into account. In every case, the statutory provisions and regulations of municipal wastewater plants must be adhered to. Information is provided by municipal wastewater plants as well as by environmental agencies.

Maintenance and cleaning

To achieve an optimum lifespan for the ultrasonic/rinsing bath, cleaning and maintenance should be conducted regularly.

CAUTION!

Disconnect the bath from the mains before each cleaning/maintenance.
Do not rinse or immerse the ultrasonic bath in water and do not expose it to splash water.
No guarantee will apply to damage caused by the use of unsuitable surface disinfection agents or detergents.

Cleaning and care

Oscillating tank
The oscillating tank of an ultrasonic bath is a worn part. It is continuously exposed to cavitation during ultrasound operation. Dirt particles remaining in the tank abrade and damage the tank surface due to the movement of the ﬂ uid, therefore

Thoroughly and frequently rinse the oscillating tank with water and wipe dry with a soft cloth.
Regularly remove residue and scum from the oscillating tank using a commercial stainless steel cleaning product without any abrasive additives.
Do not use steel wool, scrapers or graters for cleaning/maintenance.
Metal particles that remain on the stainless steel surface as well as rust particles from the water pipe system penetrate the passive protective layer of the stainless steel. The stainless steel is “activated” in this process and begins to rust. The extraneous rust produces localized corrosion of the stainless steel. For this reason, remove metal parts such as screws, ﬁ lings, etc. from the oscillating tank, and immediately remove rust stains using a soft cloth and a commercial stainless steel cleaning product without abrasive additives.

Housing

Do not use any abrasive cleaners, only commercial care products without abrasive additives.
The exterior of the housing should be wiped down with a damp cloth and left to dry, or wiped dry.

Warehousing/storage
During long periods of non-use, the ultrasonic/rinsing bath must be stored in a cool, dry location. The lid should be placed on top to protect the bath from outside contamination.

Maintenance and repair

Maintenance
SONOREX TECHNIK ultrasonic/rinsing baths are maintenance-free. For purposes of regular inspection, the following functional checks may be carried out.

Functional checks
Checking control lights

Under chapters 3.1.1 and 3.1.2.

Checking the ultrasound and/or heating
The function can be checked using a standard wattmeter. It should be inserted between the ultrasonic bath’s mains plug and the socket.

Fill the tank with fluid, see Chapter 4.2.
For testing purposes, only the ultrasound or the heating system should be plugged in. Next, the value displayed is to be compared with the corresponding value in the technical data (chapter 1.4) (tolerances ± 20 %).

Checking the ultrasound effect

For this check, it is recommended that a foil test be conducted (semi-annually). Ordinary aluminum foil is used to conduct the test. Next, a comparison is made with previously generated foils, if applicable. Detailed information is available upon request.

Error analysis
SONOREX ultrasonic and rinsing baths are robustly constructed and designed for a high level of reliability. Nevertheless, the possibility of a malfunction due to a defective component can never be fully discounted. The following overview of possible sources of error should serve as an aid for error detection and elimination.

Ultrasonic bath oscillates weakly, unevenly, or the noise is too loud:
- Has fluid been properly degassed?
- Treat for 30 min.
- Is it overloaded with objects to be treated?
- Remove a few parts.
- Uneven noises (wobbling)
- No error – slightly adjust the fill level of the fluid.
Heating system defective?
The ultrasonic bath can be readily operated without heating.
Slight erosion visible on the bottom of the bath?
- Natural wear. Ultrasonic bath OK. Strong erosion marks appear at the tank bottom
- lead to loss of power

Any malfunctions must be communicated in writing to the manufacturer.

Detailed specifications can be found in the Operating Instructions for the respective device.

Lifting device with oscillation MB
The electrically-driven lifting device with oscillation facilitates the lifting and lowering of the goods basket. The cleaning efficiency is increased and loosened dirt particles are rinsed off .

Tank rack WG
Tank racks for positioning the lifting device are designed for 2 to 4 tanks.

Filtration FA
Thanks to continuous filtering of the loosened particles, the lifetime of the tank is increased and the cleaning power is preserved.

Oil separator OX
To be connected to the ultrasonic cleaning tank when cleaning very oily or greasy parts. Impurities that rise to the surface of the tank are led via the weir into the oil separator, where they are separated by gravity. BANDELIN-
RM-16.2-UH-Electronic-GmbH-FIG-13

DI water treatment device WA
To be connected to a rinsing tank. Used to eliminate any water residue that could leave spots on the treated objects during the drying process.

Trough dryer TO
The treated objects are dried after rinsing, to quickly remove any residual moisture.

Chemical preparations – Recommendations
Ultrasound applications require special preparations that are suitable for use with ultrasound, i.e. cavitation-conducive, biodegradable, easily disposable, gentle to thematerial and long-lasting. BANDELIN recommends the TICKOPUR or STAMMOPUR concentrates by DR. H.STAMM GmbH, which have been especially developed for ultrasound use and which utilise the ultrasound optimally. Additional information may be obtained from our supplier, our sales representatives, or from our website.

Example of a possible cleaning sequence using peripheral devices
The SONOREX TECHNIK Modular Program can be assembled individually. It is comprised of eﬃ cient ultrasonic baths and rinsing tanks in different sizes with and without heating, as well as a large variety of additional equipment to facilitate work, extend the lifetime of the tanks, and dry the cleaned parts. BANDELIN-RM-16.2-UH-Electronic-GmbH-FIG-15

The electric lifting device with oscillation MB enables the lifting and lowering of the basket and provides an up and down motion in the bath during the cleaning process, improving the cleaning eﬀ etc. The modular system allows for individual assembly of these items depending on the cleaning task. A significant advantage is that the system can be expanded at any time.
