Slide hose E onto connector D. F G Check the discharge hose connection for freedom from leakage. Escaping water can lead to damage of objects in the vicinity. Remove the mains plug from the socket before checking the discharge hose connection for leakage. ! 2/8/2012 Retsch GmbH Escaping water can cause electric shocks.
Operation Target group: Operators Controls and operation Graphical representation of the controls: 1 4 2 3 Overview table No. Description Function 1 2 Power cord Ball valve 3 4 Discharge hose Knob Connects the ultrasonic cleaner to the mains power supply. Open = Liquid can flow off from the vibratory trough Closed = Liquid is prevented from flowing out of the vibratory trough. Connects the ultrasonic cleaner to a water collecting point.
Operation of the ultrasonic cleaners Target group: Operators Switching on and off The ON/OFF knob is located on the front of the ultrasonic cleaner. Turn the knob to the position. The signal lamp lights up in green. The ultrasonic cleaner is in continuous operation and will not switch off automatically. Turn the knob to the 0 position. The signal lamp goes out. The ultrasonic cleaner is then switched off. Setting the time Running times of 0 - 15 mins. can be set by turning the ON/OFF knob clockwise.
Cleaning with the ultrasonic machine The UR1 is suitable for cleaning of analysis sieves up to 215 mm in diameter, and the UR2 up to 450 mm diameter. In each cleaning operation, ensure that the material to be cleaned is completely covered by the cleaning and contact fluid. Fill the vibratory trough to at least 2/3 capacity with cleaning/contact fluid, with 5 - 10% ”TICKOPUR RW77” cleaning fluid, available as an accessory, added.
Emptying the vibratory trough Always remove the mains plug before emptying the vibratory trough. There are two ways to empty the vibratory trough in the ultrasonic cleaner. Grip the UR with both hands and tip the liquid into a sink as with a saucepan or place the ultrasonic cleaner near a sink in such a way that hose 3 reaches into the basin. Allow the liquid to drain off by opening ball valve 2. The position is shown in the figure. 2 3 Always remove the mains plug before emptying the vibratory trough.
Notes on operation Target group: Operators Cleaning The ultrasonic bath gently and intensively cleans analysis sieves, microprecision sieves, glass and metal parts, and metallographic and geological samples, spectacles, jewellery, coins and many other objects. The ultrasonic bath can also be used for processes other than cleaning. Homogenising The RETSCH ultrasonic bath is used in particle metrology for preparation of suspension samples for wet sieving or sedimentation analysis.
General Target group: Operators Ultrasonic machine technology A high frequency generator produces approx. 35,000 oscillations per second which are transmitted to the cleaning fluid and cause it to resonate. The energy density of the sonic field is so high that cavitation takes place. Countless small vacuum bubbles are created and collapse within microseconds as a result of pressure and suction: they implode.
Maintenance Target group: Operators The ultrasonic machines are extensively maintenance-free. Have any necessary repairs performed by authorised specialists or direct by Retsch GmbH only.
