Never switch ON the ultrasonic cleaning device without cleaning fluid. Also ensure that the fluid level is high enough during operation. 3 6 Safety Information The temperature can rise and develops a large amount of steam as a result of heating or the energy from ultrasonic effect. Hence ensure that there is adequate ventilation at the installation site. Fluid should not get inside the cleaner. Wipe off any fluid which has overflowed and is running down the side walls as soon as possible. The parts to be cleaned may not be laid or placed directly at the bottom of the tank. Please use a basket to contain the parts. Never leave the ultrasonic cleaner unattended during operation. If the cleaner does not have to be ready for immediate operation, disconnect it from the power supply system (unplug). Never turn ON the cleaner if it has been damaged. Inspect the cleaner and its power cord for external damage at regular intervals. Repairs may only be carried out by the manufacturer. Observe the statutory regulations when disposing of the cleaning fluid. DANGER: Always ensure that a power cord with a protective earth conductor (PE) is used. Never use power cord without a protective earth conductor. CAUTION: Ultrasonic energy. Never put your hands in the tank when the ultrasonic is ON. Always switch OFF the ultrasonic when inserting or removing the parts to be cleaned. Cleaning fluid The cleaning fluid used depends on the material of the parts to be cleaned and the type of soiling. Please contact the manufacturer for advice about the cleaning agent. 2. START- UP Check that the main connection, which must be equipped with a protective earth conductor, conforms with the data on the rating plate of your cleaner. Set up the ultrasonic cleaner on a firm, dry and level base. Fill the cleaning tank with water and add a suitable cleaning agent, depending on the cleaning application. Please take note of the respective safety regulations for handling chemicals.http://www.eversit.nl/site/data/ws/page/carbohydrate-counting-nutrition-care-manual.xml

Connect the ultrasonic cleaner to the main connection and switch on the power switch located at the side. When the cleaner has been switched on, the green indicator light in the switch is lit. The cleaner is now ready for operation. Ensure without fail that you use the correct power cord for the socket outlet. DRAIN NOTES: Models with no drain valve: CP200; CP 230; CP 360; CP 500 Models with drain valve: CP 1100; CP 1200; CP 1800; CP 8 Operation 4. OPERATION 4.1 Ultrasonic cleaner Model 'T' and 'HT' These models have a mechanical time switch which allows a variable operating time of the sonic from 1 to 30 minutes or continuous operation. The continuous sonic function is obtained by turning the knob counter-clockwise from the '0' position to the latching point. For time below 2 minutes, first of all set the time switch to a longer time and then turn it back to the desired operating time. This is inherent in the design. A green LED is lit during the sonic operation. The sonic energy applied to the fluid is visible in the form of cavitations on the surface of the fluid. In the 'HT' series, a bath heater is connected to support the cleaning task. The bath s temperature is adjustable up to 80 C (176 F). When the heater is on, a yellow LED is lit. The LED turns off once the bath preset temperature is reached. 4.2 Ultrasonic cleaner Model 'D' The cleaner has a digital interface panel which enables settings and its operation. The following settings are possible: Sonic turn-on duration from 1 to 99 minutes in steps of 1 minute or continuous operation, Bath temperature in steps of 1 C (33 F) to 80 C (176 F). Sonic power in nine steps from approx. 40% to 100 % of max.Although the cleaning fluid is also degassed in normal operation, this can considerably speed up in the DEGAS mode, with that the following cleaning operation is considered to be more effective and uniform. During the DEGAS mode, the sonic is switched ON and OFF in short intervals.

This causes the entrapped air to form into larger bubbles during the acoustic cavitation of the fluid. If the preset temperature has not been reached, the decimal point in the display blinks; the bath is being heated. Once the preset temperature has been reached, the decimal point will stay lit all the time. The 'Time' display blinks. The timer function can be rendered inoperative by pressing the '-' button until two horizontal lines are shown in the display. With this continuous operation mode is active. Setting the bath temperature With the sonic off, press the 'Select' button until the 'Temperature' display blinks. Ultrasound 'OFF': With the sonic switched off, press the 'Select' button until the 'Power' display blinks. Degassing the fluid (DEGAS) In order to obtain an optimum cleaning action after the cleaner has been drained and refilled, the fluid must first of all be degassed, since the cleaning action is impaired by the bound gas bubbles (usually ambient air). Ultrasonic cavitations remove these gases. The cleaner is periodically switched ON and OFF during the DEGAS mode. The gas bubbles rise up in the fluid during the sonic OFF period. Degassing can be sped up by adding a few drops of surfactant (e.g. liquid detergent) to the cleaning fluid. Most ultrasonic cleaning agents already contain a surfactant. The degassing process does not have to be repeated when reusing the same cleaning fluid. Heating the cleaning bath If a specific bath temperature is required for the cleaning operation, the cleaning bath can be heated up to a preset temperature (See the process 'Setting the bath temperature'). Normally the cleaning process is considerably more effective if the cleaning fluid is heated. If necessary, use the cleaning basket which is available as an accessory part. Set the required cleaning time and temperature for the cleaning process and, in the case of the D models, the ultrasonic output power as well.

The parameters 'Cleaning time' and 'Sonic power' depend on a great extent on the cleaning fluid, temperature, type of soiling as well as on the degree of soiling of the parts to be cleaned. The time can vary from a few seconds to a few minutes. An optimum combination of the parameters may have to be determined through experiments. Now start the cleaning operation by switching on the sonic. After cleaning, remove the parts from the bath with care. We recommend rinsing the parts in clean water. Disconnect the cleaner from the main power when it is not in use. Important: Please note that the bath temperature rises considerably with lengthy ultrasonic operation. If the bath temperature reaches approx. 90 C (194 F), the heater and the ultrasonic are switched off for safety reasons. In the case of the 'D' model, the error message 'Unit too hot' (running text) appears in the display. Never lay the parts to be cleaned directly on the bottom of the tank. Never clean too many parts at once, the cleaning may deteriorate. 10 13 Operation 4.5 Emptying the tank When the sonic cavitation in the bath becomes noticeably weaker or the fluid is very dirty, the cleaning bath should be changed. 4.6 Accessories Stainless steel tank cover To prevent evaporation of the bath fluid and odour. Stainless steel cleaning basket For containing of the parts to be cleaned. The basket can be suspended in the cleaning bath. Proper Procedure for Using Auxiliary Pans and Beakers When a beaker is used, place in a beaker positioning cover using a beaker 0-ring to adjust the suspension so beaker bottom is just below the surface of the solution level in the main tank but off the tank bottom. Cavitation will be transmitted from the main tank to the auxiliary pan or beaker. More than one beaker can be used at a time depending on the model. Beaker positioning cover with hole or holes (various sizes) - easy cleaning of small and delicate parts. - lower consumption of cleaning fluid.

- cleaning using various cleaning agents. The sonic is coupled to the filled beaker via tank water as the medium. Fill the cleaning tank with water and add a surfactant (e.g. liquid detergent). 11 14 Operation Auxiliary Pan Fill stainless steel tank to fill line with proper ultrasonic cleaning solution and clean normally. Fill auxiliary pan or beaker with another designated ultrasonic solution to a level just above item to be cleaned or rinsed. The auxiliary pan or beaker will now function as another ultrasonic cleaning machine when used properly. Place auxiliary pan into main tank, resting it on its handles, making sure that the bottom of the auxiliary pan is below solution level. Several combinations may be utilized. It is recommended that additional covers be placed on the auxiliary pans to reduce evaporation loss and fumes. Auxiliary pan - secondary cleaning, rinsing or degassing. The sonic is coupled to the filled auxiliary pan via tank water as a medium. Fill the cleaning tank with water to the proper operating level and add a surfactant (e.g. liquid detergent). 12 15 5 MAINTENANCE Maintenance The ultrasonic cleaner is maintenance-free. Nevertheless, you should take note of the followings: Keep the ultrasonic unit clean. Occasionally wipe the housing with a damp cloth. Remove any cleaning agent residues immediately. Ensure that the cleaning fluid does not soil the housing during cleaning. Clean or change the cleaning fluid as required. Avoid scratching the floor of the tank. This leads to accelerated cavitation pitting (erosion). As a result, please ensure that the parts to be cleaned have no direct contact with the floor of the tank. For best results keep tank as clean as possible only allowing small amounts of dirt to accumulate on the floor of the cleaning tank. If necessary, the cleaning fluid should be drained so that the bottom of the tank can be cleaned. Check the cleaner and the power cord for damage at regular intervals as well as before use.

A visibly damaged cleaner must not be used and must be disconnected from the power supply source. Do not perform repairs yourself. Send the cleaner to the manufacturer for servicing. 13 16 Annex 6. ANNEX 6.1 Technical data Use the cleaner for small scale cleaning tasks. As a result, it has high resistance to solvents. It is tougher and more durable than other foils generally used for plastic foil keyboards and front panels, such as e.g. polycarbonate and PVC. The error message appears in the form of running text which runs through the display: Sonic Error In this case, an error has been detected in the ultrasonic generator or the generator control system. Switch the ultrasonic cleaner off and on again by means of the power switch. Start the cleaning operation once again. If the error message reoccurs, the device must be sent to the manufacturer for servicing. Unit Too Hot Src - H In this case, the thermal protection device has switched off the heater and the sonic.
