SONOBOARD Standard functional cabinet 1 4 (ST 30 DT) 5 1.1 Mode of operation SONOREX ZE ultrasonic baths use the effect of cavitation. Under their oscillating tank bottoms or additionally on the tank well 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 fl uid, releasing energy upon imploding and generating local microcurrents. This process is called cavitation. During the cleaning process, contamination is "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. SONOREX ZE ultrasonic baths are effi ciently supported by SweepTec automatic frequency control. SweepTec immediately balances load-dependent working point fl uctuations to the optimal working point using fast frequency modulation. This produces an especially homogeneous and uniform ultrasound field in the bath volume for constantly reproducible results. 6386d GB/2017-09 7 / 40

1.2 Purpose General use SONOREX ZE ultrasonic baths are intended for the sonication of aqueous fl uids. 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 diffusion of the ultrasound can only be guaranteed in this manner. The ultrasonic bath is to be operated from the front if possible, and should always be operated with the bath installed. Ultrasound treatment of medical instruments SONOREX ZE ultrasonic baths are used to treat medical instruments: a) during manual treatment b) before machine treatment c) after machine treatment In this connection, they are to be used together with suitable, non-fi xative disinfection and/or detergent preparations, in order to support or expedite their effect. Pursuant to section 2, para. 1 and section 3, paras. 1, 9 and 10 of the Medical Devices Act (MPG), the ultrasonic bath thus becomes a medical device as an accessory to the preparations and is to be treated as one. This includes pre- and post-processing steps for the medical instruments, e.g., the observance of RKI recommendations in "Hygiene requirements for the treatment of medical products" 1 and other applicable domestic regulations. Additional information in this respect can be found in Chapter 4.3. 1.3 CE conformity SONOREX ZE ultrasonic baths are declared as medical products and satisfy the CE marking criteria for the European - Medical Devices directive - "Low-voltage directive" - "Electromagnetic Compatibility" Directive in their currently valid versions. A declaration of conformity can be requested from the manufacturer by providing the serial number. 1 Recommendation of the German Commission for Hospital Hygiene and Infection Prevention (KRINKO) at the Robert Koch Institute (RKI) and the German Federal Institute for Drugs and Medical Devices (BfArM); Federal Health Gazette - 2012 55:1244-1310 8 / 40 6386d GB/2017-09

1.5 Warnings and safety precautions General Keep the ultrasonic bath out of the reach of children and also of persons who have not been instructed in their operation by reference to these instructions. We will not offer a guarantee for damages to the ultrasonic bath or oscillating tank, or to the objects to be treated, as a result of use of inadequate disinfection agents or detergents. Keep the HF generator surfaces and the control unit clean and dry. Do not expose the ultrasonic bath to corroding infl uences. Empty the ultrasonic bath only while turned off. Ultrasonic baths adhere to prescribed EMC limit values, such that it can be assumed that the electromagnetic radiation emanating from the ultrasonic baths 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 should be obtained from the implant manufacturer. Operation Never operate the oscillating tank without the cover on the transducers! Only turn on the generator if the bath is connected (HF cable) never run the generator without a load. Observe ambient and set-up conditions, see section 1.4. Only plug in the ultrasonic bath to an outlet with a grounded socket. Do not use a rubber plug or stand pipe on the oscillating tank's outlet! Do not operate the ultrasonic bath without fl uids. Do not stand or lay any objects on the tank bottom, accessories must be used, see section 7. Do not immerse any parts of the body (e.g. hands, feet) or living beings (animals or plants) into the tank; in particular, do not immerse them in the ultrasonic fluid during ultrasound operation. Danger: Ultrasound has a cell-destroying effect. In the event of continuous activity within a 2 m radius, adequate hearing protection must be used. Danger: Hearing disturbances during operation when not wearing hearing protection the typical ultrasound cavitation noise can be perceived as uncomfortable. When used for extended periods, the bath fl uids heat up. For this reason, it is important to check the temperature when treating temperature-sensitive parts. Do not leave the ultrasonic bath unattended while in operation. 12 / 40 6386d GB/2017-09

Advice for the medical field The ultrasonic bath is exclusively intended for use by skilled medical personnel. It may generate radio interference or disrupt the operation of devices nearby. It may be necessary to take remedial measures such as realigning the device or reconfi guring the ultrasonic bath or the shield. During operation, portable or mobile HF communication systems in the vicinity of the ultrasonic bath should be turned off their operation may be disrupted. When handling contaminated instruments, relevant personnel protection regulations are to be observed. When treating instruments, the instructions of the instrument manufacturer are to be followed. Ultrasound cleaning is especially suitable for instruments made of stainless steel and hard plastics. Do not treat lenses, camera systems or light cables with ultrasound. A combined disinfection and cleaning of medical instruments in the ultrasonic bath is only possible with the use of special preparations (with the corresponding microbiological certifi cates). Ultrasound alone will not disinfect them! Damage If damage to the ultrasonic bath is detected, do not connect the ultrasonic bath to the mains. In the event of defects, disconnect the mains plug immediately. Repairs are only to be conducted by authorised skilled personnel or by the manufacturer! Defective parts may only be replaced with original SONOREX parts. 2 Preparation Carefully unpack the ultrasonic bath components and accessories, and inspect them for completeness or possible transportation damages. If any damage or defects are found, these must be immediately notifi ed in writing to the transportation company and to the supplier. Before operation, the ultrasonic bath should be allowed to stand for 2 hours at its operating location so that it can adjust to the ambient conditions. 6386d GB/2017-09 13 / 40

4 Use Direct sonication Normally, sonication takes place directly in the oscillating tank. For this purpose, the objects to be treated are placed in a basket and placed on a basket holder inside the oscillating tank which is fi lled with sonication fl uid. Basket holder with basket Sonication fl uid 4.1 Instructions for use Instructions - filling Verify that the outlet is closed. The ultrasound bath must be turned off. Do not fi ll oscillating tank with hot water. Maximum fi lling temperature: 50 C. Water of at least drinking quality must be used to fi ll the oscillating tank. Water without additives is not suitable for sonication. BANDELIN recommends 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! 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 working with aggressive preparations in inset beakers or insert tubs: Prevent the contact liquid or stainless steel surfaces from being sprayed. If necessary, replace the contact liquid, clean the surfaces and wipe dry. When using preparations, the safety instructions included in the respective product leafl ets and safety data sheets are fundamentally to be adhered to. Replace used sonication fl uids, do not refresh by adding fl uids. Notes - Inserting objects Fully remove air bubbles from cavities (e.g. blind holes). Indirect sonication Fully remove possible air bubbles from underneath the vessels. 18 / 40 6386d GB/2017-09

Notes - Temperature Warmed-up fl uids intensify the ultrasound effect. Experience has shown that the best results are obtained with a bath temperature of 50 to 60 C. At high temperatures, the effi ciency of the ultrasound cavitation decreases again 2. Ultrasound energy warms up the sonication fl uid (even without additional heating). The temperature of the bath fl uid can increase rapidly if the ultrasound is active for long periods of time and/or the oscillating tank is covered. For this reason, the temperature must be controlled when treating temperature-sensitive components. For an optimum bath temperature, observe the specifi cations of the specimen manufacturer! Mix disinfectant with cold water, run ultrasonic bath without heating, avoid temperatures of >40 C. 2 MILLNER, R.: Wissenspeicher Ultraschalltechnik, Fachbuchverlag publishing house, Leipzig 1987 6386d GB/2017-09 19 / 40

4.2 General application Step 1: Fill oscillating tank The oscillating tank is fi lled with water and a suitable preparation to reduce the surface tension, see Chapter 7.3. Direct sonication Fill 1/3 of oscillating tank with water. Add dosed preparation to the oscillating tank. See appendix for dosage information. Fill carefully up to the fi lling level mark, avoid as much as possible the formation of foam. Step 2: Degassing the fluid Freshly-fi lled bath fl uid or fl uid that has remained in the oscillating tank for a longer period of time must be degassed prior to use. See also section 4.4.1. Remove basket and other accessories from the oscillating tank. Place lid on top. Set the degassing time and start the ultrasound (control unit ST 15.1) or activate the DEGAS function (control unit ST 30), see Section 3. - up to 10 litres bath volume: 10 min - more than 10 litres bath volume: 30 min Time may need to be extended with acidic cleaning solutions. Step 3: Insert objects to be treated Before sonicating each time, check whether the service life of the bath fl uid has expired, or whether the bath fl uid is contaminated and needs to be replaced. Direct sonication Place the basket holder in the oscillating tank. Place the inset basket on the basket holder. Check that the objects to be treated are fully covered with fl uid. Check the fi ll level. Oscillating tank with basket holder 2/3 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. An overloading of the basket or inset beaker reduces 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. 20 / 40 6386d GB/2017-09

Delicate parts are not to come into contact with one another - for positioning, use special accessories such as silicone knob mats if necessary, see Chapter 7.2. Due to the design, the ultrasound effect is weaker on the outlet side. Do not place more heavily soiled objects in the basket over the outlet. Step 4: Ultrasound operation Fundamentally, the sonication time is to be as short as possible in order to protect the objects to be treated and the oscillating tank. In the case of disinfection fl uids, the length of time will depend on the concentration of the preparation used. In the case of stubborn residue, it may be necessary to conduct sonication for a longer time. Place lid on top. Set the required sonication period and start the ultrasound, see Chapter 3. Step 5: Remove treated objects After sonication, the objects are to be removed from the ultrasonic bath. Allowing them to remain any longer in the bath fl uid may damage them. Turn off the ultrasound. Remove the basket or inset beaker from the tank and set down atop a level surface. Depending on the length of sonication, the baskets and objects may be hot! After the cleaning processes, rinse the treated objects with water of at least drinking quality. Next, visually check the sonication results. Before the next sonication, verify the service life of the bath fl uid. Heed the specifications of the preparation manufacturer. If necessary, empty the oscillating tank. Step 6: 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 4.4.2. Turn off the ultrasonic bath. Empty the oscillating tank by opening the drain. After emptying the oscillating tank, thoroughly rinse it. Wipe dry with a soft cloth. For additional care instructions, see Chapter 5.1. 6386d GB/2017-09 21 / 40

4.3 Treatment of medical and dental instruments The disinfection and cleaning of medical instruments in a single step follows the general sonication procedure, see Chapter 4.2. A combined disinfection and cleaning of medical instruments in the ultrasonic bath is only possible with the use of special preparations (with the corresponding microbiological certifi cates). Ultrasound alone will not disinfect them! Only disinfecting agents and/or detergents that are non-affi xing may be used. In terms of concentration, temperature, and sonication time, the manufacturer specifi cations for the disinfecting agent and/or detergent used are to be strictly adhered to. The compatibility between the instrument and the preparation is to be verifi ed on the basis of the respective manufacturer's specifi cations. The service life of the disinfection solution pursuant to the manufacturer specifi cations is to be heeded. The cleaning solution is to be immediately replaced if contamination is evident. It is to be replaced, however, at least every work day. Prepare instruments appropriately, e.g., by rinsing them with cold water of at least drinking quality, fully separating / opening them! Adhere to the instructions of the respective instrument manufacturer. Operate the ultrasonic bath with a lid or beneath a suctioning system. Further treat instruments after sonication in accordance with RKI recommendations 3. Adhere to OSHA safety measures (e.g., protective clothing, protective goggles, suitable gloves). Special case "thorough cleansing" In the case of stained, crusted or oxidised instruments, a thorough cleansing is recommended. The thorough cleansing is carried out as indirect sonication in a plastic insert tub, using a special detergent (see Chapter 7.2). 3 Recommendation of the German Commission for Hospital Hygiene and Infection Prevention (KRINKO) at the Robert Koch Institute (RKI) and the German Federal Institute for Drugs and Medical Devices (BfArM); Federal Health Gazette - 2012 55:1244-1310 22 / 40 6386d GB/2017-09

4.4 Further information 4.4.1 Degassing The degassing of the sonication fl uid increases the ultrasound effect. Freshly filled-in fl uid or fl uid that has remained in the oscillating tank for a longer period of time must be degassed prior to use. Gases dissolved in the fluid (e.g. oxygen) are reduced through degassing and the ultrasound effect is thus signifi cantly improved. The cavitation noise changes during degassing, loud degassing noises fade away 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. Rather, it signifies the end of the degassing process and an improvement in the ultrasound effect. 4.4.2 Disposal of sonication fluids All aqueous preparations made by DR. H. STAMM GmbH are prepared pursuant to the regulations of the German Washing and Cleansing Agents Act, are biodegradable, and may be added to sewerage as bath fluids, see Chapter 7.3. Disinfecting and cleaning agents that become contaminated when used are considered "waste material" pursuant to the German Waste Act (AbfG) and may not be taken back by the manufacturer. 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. 6386d GB/2017-09 23 / 40

5 Cleaning and maintenance of the ultrasonic bath To achieve an optimum lifespan for the ultrasonic bath, cleaning and maintenance should be conducted regularly. CAUTION! Disconnect the ultrasonic bath / HF generator from the mains before cleaning / maintenance. Do not rinse or immerse the ultrasonic bath and HF generator in water and do not expose them to splash water. The guarantee will not apply to damages caused by the use of unsuitable disinfecting agents or detergents. 5.1 Cleaning and care Oscillating tank The oscillating tank of an ultrasonic bath is a wearing 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 Rinse the oscillating tank with water thoroughly and frequently and dry using a soft cloth. Regularly remove residue from the edges of 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 it begins to rust. The extraneous rust produces localised 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. HF generator housing Do not use any abrasive cleaners, only commercial care products without abrasive additives. The housing is to be wiped off only from the outside with a moist cloth; afterwards, allow to dry or wipe dry. 24 / 40 6386d GB/2017-09

5.2 Disinfection If contaminated medical instruments are treated in the ultrasonic bath, hygienic safety after use is important. In order to avoid any cross-contamination as a result of the settling of microorganisms, especially along the tank edge and in the drain outlet area, but also on the user interfaces, these areas are to be regularly cleaned and disinfected pursuant to the hygiene plan using a VAH-certifi ed or effective surface disinfectant. Accessories such as holders and baskets should be processed regularly in a cleaning and disinfection device. 5.3 Positioning / Storage During long periods of non-use, the ultrasonic bath should be stored in a cool, dry location. The lid should be placed on top in order to protect the oscillating tank from outside contamination. 6 Maintenance and repair 6.1 Maintenance SONOREX ZE ultrasonic baths require no maintenance. For purposes of regular inspection, the following functional checks may be carried out. 6386d GB/2017-09 25 / 40

6.2 Function test / functional check Check the control light on the ST 15.1 Pursuant to Chapter 3.1.1. Check the control lights on the ST 30 DT A test routine can be started for an internal function check: To do so, the ultrasonic bath must be switched off. When the Start/Stop button is pressed and held, the ultrasonic bath is switched on with the ON/OFF button. All LEDs light up successively for 1/3 of a second. The last set values are then displayed. The test is then successfully completed. If there are any deviations, the ultrasonic bath must be sent in for checking/repairs. Check the ultrasound effect For this check, it is recommended that a foil test be conducted (semi-annually). The oscillating tank is delivered along with a frame suitable for foil tests. Ordinary aluminium foil is used to conduct the test. Next, a comparison is made with previously-generated foils. For more detailed information, please see the appendix. A measurement procedure is described in DIN SPEC 40170:2013-11 (measurement and evaluation of the cavitation noise). 6.3 Error analysis SONOREX ultrasonic 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 noise is too loud: - Has fl uid been properly degassed? See Chapter 4.2 / Step 2 : Degassing the fl uid. - Is it overloaded with objects to be treated? - Uneven noises (wobbling) Remove a few parts. No error slightly adjust the fi ll level of the fl uid. Slight erosion visible on the tank bottom? Natural wear. Ultrasonic bath OK. Any malfunctions must be communicated in writing to the manufacturer. 26 / 40 6386d GB/2017-09

B Foil test Information Foil test Testing of ultrasonic baths A foil test 1 is recommended for testing ultrasonic baths. It is to be conducted upon initial startup, and at regular intervals thereafter (e.g. every 3 months). The frequency of testing is the responsibility of the user. The foil test is a simple procedure to demonstrate the intensity and distribution of cavitation in an ultrasonic bath. To do so, aluminium foil is stretched over a foil test frame. It is perforated or destroyed to a certain degree by cavitation, depending on the duration. For purposes of reproducibility, it is important that the test conditions remain constant: Fill level in the oscillating tank (² ) Fluid for the foil test In order to obtain an adequately strong cavitation effect, the surface tension of the water used must also be reduced for the foil test with the help of surfactant preparations. We recommend the following ultrasound preparations: STAMMOPUR DR 8, STAMMOPUR R, TICKOMED 1, TICKOPUR R 33, TICKOPUR R 30, TICKOPUR TR 7 If none of these preparations is available, a neutral or mildly alkaline preparation that does not destroy aluminium may be used. The preparation must be approved by the manufacturer for use in ultrasonic baths. Temperature of tank contents Degassing time, if needed (degassing 5 to 30 min. before the test, depending on the tank contents) Time may need to be extended with acidic cleaning solutions. Frame positioning Foil properties (thickness, surface) Sonication time Concentration and type of ultrasound preparation Foils can be archived in a suitable way (scanning, photos, etc.) This allows the foils to be compared at any time. The perforated areas of all foils should have approx. the same dimensions and distribution the results are never identical. A process validation, e.g. for the treatment of medical products, can only be achieved by conducting regular foil tests. To execute the foil test, different foil test frames FT can be ordered from the manufacturer (for a fee). The foil test frames are suitable for a wide range of tank dimensions. Aluminium household foil is also required to conduct the test and is not included in the delivery. Film: http: /bandelin.com/folientest/. 1 Investigations on test procedures for ultrasonic cleaners.

Conducting the foil test 1. Fill 2/3 of the oscillating tank with water and a suitable ultrasound preparation in the dosage specified by the manufacturer. 2. Degas the liquid: < 10 l - 10 min and > 10 l - 30 min (see user instructions.) 3. Stretch aluminium foil (household foil with a thickness of 10 m to 25 m) over the wire frame (stainless steel). Depending on the tank size, it is possible that the frame protrudes from the tank. Covering the portion of the frame that is submerged will suffice. Frame Ø 3 mm 5. Switch on the ultrasound and sonicate the foil for at least one minute until visible perforations or holes are produced. With sturdier foils (thicker or coated ones), the sonication time can last up to 3 minutes. 6. Switch off the ultrasound, take the foil out and let it dry. 7. The foil must be perforated, otherwise contact the manufacturer. Aluminium foil, folded 10mm along the edge 4. With the ultrasound switched off, place the foil-wrapped wire frame diagonally inside the oscillating tank, adjust if necessary. 8. Archive it together with testing date and the serial number of the ultrasonic bath. 9. After the test, the oscillating tank must be thoroughly rinsed out to remove any loose foil particles. for interior tank dimensions in mm (L x W x H) Type from to Order No. FT 1 190 85 60 3190 FT 4 240 140 80 300 150 150 3074 FT 6 500 140 100 500 140 150 3222 FT 14 280 234 80 325 300 300 3084 for DT 31/H, DT 52/H RK 31/H, RK 52/H DL 102 H, DL 255 H, DT 100/H, DT 102H/H-RC, DT 103, DT 106, DT 255/H/H-RC, RK 100/H, RK 102 H, RK 103, RK 106, RK 255/H DL 156 BH, DT 156/BH, DT 1028 F RK 156/BH DL 510 H, DL 512 H, DL 514 BH, DT 510/H/H-RC, DT 512 H, DT 514H/BH/BH-RC, RK 510/H, RK 512 H, RK 514/H/BH, ZE 514/...DT FT 36 510 300 200/220 3673 ZE 1031/1032/...DT FT 37 600 400 200/220 3674 ZE 1058/1059/...DT FT 38 650 400 140/160 3672 MC 1001/E FT 40 500 300 80 500 300 300 3094 FT 42 700 420 160/190 3224 TRISON (TE 3000) FT 45 600 400 200 600 400 200 3204 DL 1028 H, DT 1028/H/CH, RK 170 H, RK 1028/H/C/CH, RK 1040 DT 1050 CH, RK 1050/CH 939w GB/2017-04 BANDELIN electronic GmbH & Co.
