Operating manual Operating manual 1. Intended use JULABO circulators have been designed to control the temperature of specific fluids in a bath tank. JULABO circulators are not suitable for direct temperature control of foods, semiluxury foods and tobacco, or pharmaceutical and medical products. Direct temperature control means unprotected contact of the object with the bath medium (bath fluid). 1.1. Description The circulators are operated via the splash-proof keypad.
ED Persons: The operator is responsible for the qualification of the personnel operating the units. The operator should be constantly informed about the dangers involved with their job activities as well as preventive actions. Make sure all persons expected to carry out operation, installation and maintenance of the unit read and understand the safety information and operating instructions.
Operator responsibility – Safety recommendations When using hazardous materials or materials that could become hazardous, the operator must affix the enclosed safety labels (1 + 2) to the front of the unit so they are highly visible: 1 Warning label W00: Colors: yellow, black Danger area. Attention! Observe instructions. (operating manual, safety data sheet) 2 Mandatory label M018: Colors: blue, white Carefully read the user information prior to beginning operation.
ED 2.2. EC Conformity The products described in the operating instructions conform to the requirements of the following European guidelines: Directive of the European Parliament and of the Council on the approximation of the laws of the Member States relating to machinery. EMC guideline with respect to legal harmonization of the member countries concerning electromagnetic compatibility. JULABO GmbH Eisenbahnstr. 45 77960 Seelbach / Germany 2.3.

ED Operating instructions 3. 3.1. Safety notes for the user Explanation of safety notes In addition to the safety warnings listed, warnings are posted throughout the operating manual. These warnings are designated by an exclamation mark inside an equilateral triangle. “Warning of a dangerous situation (Attention! Please follow the documentation).” The danger is classified using a signal word. Read and follow these important instructions for averting dangers.
Safety notes for the user 3.3. Safety recommendations Follow the safety recommendations to prevent damage to persons or property. Further, the valid safety instructions for working places must be followed. 12 Only connect the unit to a power socket with earthing contact (PE – protective earth)! The power supply plug serves as safe disconnecting device from the line and must be always easily accessible. Operation is permitted with non-flammable liquids only.
ED Caution: The temperature controlling i.e. of fluids in a reactor constitutes normal circulator practice. We do not know which substances are contained within these vessels. Many substances are: inflammable, easily ignited or explosive hazardous to health environmentally unsafe i.e.: dangerous The user alone is responsible for the handling of these substances! The following questions shall help to recognize possible dangers and to reduce the risks to a minimum.
Operating controls and functional elements 4.
ED 5. 5.1. Preparations Installation Notice: Plexiglas and Makrolon baths are not resistent to solvents. Avoid contamination of the bath fluid with solvents. Place the circulator in an upright position. Top view A ED-5A/B ED-7A/B ED-5M/B The circulator (A) mounted on a stainless steel bridge is placed on the back of the bath tank.
Preparations 5.2. Bath fluids Caution: No liability for use of other bath fluids! Do not use flammable bath fluids! Water: The quality of water depends on local conditions. Due to the high concentration of lime, hard water is not suitable for temperature control because it leads to calcification in the bath. Ferrous water can cause corrosion - even on stainless steel. Chloric water can cause pitting corrosion. Distilled and deionized water is unsuitable.
ED 5.3. Filling / Draining Notice: Filling Check the filling level of the bath fluid from time to time. Pump and heater must always be fully covered with the bath fluid! The instrument is not suited for unsupervised continuous operation. Filling Take care that no liquid enters the interior of the circulator.
Preparations Examples: Internal applications in the bath A 100 % internal bath circulation (for large bath tanks) B Reduced internal bath circulation (for smooth surface of bath fluid) External/internal applications C 40 % external discharge, 60 % internal circulation (for large bath tanks) D 80 % external discharge, 20 % internal circulation (for small bath tanks) 5.5.
ED 6. 6.1. Operating procedures Power connection Caution: Only connect the unit to a power socket with earthing contact (PE – protective earth)! The power supply plug serves as safe disconnecting device from the line and must be always easily accessible. Never operate equipment with damaged mains power cables. Regularly check the mains power cables for material defects (e.g. for cracks).
Operating procedures 6.3. Automatic / non-automatic start mode Keep depressed the key and turn on the circulator with the mains power switch. For a short while the LED temperature DISPLAY indicates the effective start mode: AUTOSTART on. AUTOSTART off. NOTE: The circulator has been configured and supplied by JULABO according to N.A.M.U.R. recommendations. This means for the start mode, that the unit must enter a safe operating state after a power failure (non-automatic start mode).
ED 6.4. Setting the temperatures Factory setting: 25 °C Setting can be carried out in the start/stop condition. 1. Press one of the keys for a short moment. The setpoint value instead of the actual value is indicated on the display for about 8 seconds. The value can now be changed. 2. Change value: Press to set a higher value. Press to set a lower value. Keep the keys depressed for the value to change fast. 3. 6.5. Press the key to store the value.
Troubleshooting guide / Error messages 7. Troubleshooting guide / Error messages + Whenever the microprocessor electronics registers a failure, a complete shutdown of the heater and circulating pump is performed. The alarm light " " illuminates and a continuous signal tone sounds. The LED temperature display indicates the cause for the alarm in form of a code. Press the key to quit the audible signal. The circulator is operated without bath fluid, or the liquid level is insufficient.
ED 8. Cleaning the unit Caution: Always turn off the unit and disconnect the mains cable from the power source before cleaning the unit. Prevent humidity from entering into the circulator. Electrical connections and any other work must be performed by qualified personnel only. Plexiglas and Makrolon baths are not resistent to solvents. Do not use detergents containing alcohol or solvents.
