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. indicates a hazardous situation which, if not avoided, will result in death or serious injury.
Safety Notes 5.3. Safety instructions Follow the safety recommendations to prevent damage to persons or property. Further, the valid safety instructions for working places must be followed. • Only connect the unit to a power socket with earthing contact (PE – protective earth)! • The power supply plug serves as a safe disconnecting device from the line and must always be easily accessible. • Place the instrument on an even surface on a pad made of non-inflammable material.
F250, F500, F1000 6. Moving up and connect Risk of injury for hands. Close cover carefully. Carry the unit with 2 persons. Wear safety shoes. 6.1. Transportation and site conditions F250 Caster platform (Order No.: 8910045 F500, F1000 Transport 1.951.4806-V1 • Lifting and Transport: At F250: Lift the unit with two persons taking hold of its bottom plate. For transport set the unit on a suitable caster platform (Order No.: 8910045).
Moving up and connect 6.2. Tubing Damage caused by leaking bath fluid! • Employ suitable connecting tubing • Make sure that the tubing is securely attached. • Avoid sharp bends in the tubing, and maintain a sufficient distance from surrounding walls. • Regularly check the tubing for material defects (e.g. for cracks). • Preventive maintenance: Replace the tubing from time to time.
F250, F500, F1000 F250 • • • F500, F1000 • • 1.951.4806-V1 Before operating the unit after transport, wait about one hour after installation. This will allow any oil that has accumulated laterally during transport to flow back down, thus ensuring that the compressor can develop its maximum capacity. Remove cap screws from the connections. Connect the tubing from the external system to the pump connectors and check for leaks.

Operating procedures 8. Operating procedures 8.1. Bath fluids No liability for use of other bath liquids! Please contact JULABO before using other than recommended bath fluids. JULABO takes no responsibility for damages caused by the selection of an unsuitable bath fluid Do not use alcohols. 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.
F250, F500, F1000 8.2. Power connection Danger of electric shock! • Only connect the unit to a power socket with earthing contact (PE – protective earth)! We disclaim all liability for damage caused by incorrect line voltages! • 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 8.4. Switching on / Start - Stop Switching on: • The recirculating cooler is turned on and off with the mains switch (1). The unit performs a self-test. All segments of the 4-digit LED temperature DISPLAY and all indicator lights will illuminate Then the software version and the type of unit is indicated. The display "OFF" indicates the unit is ready to operate (standby mode). 8.5. Start: Press enter for about 4 seconds.
F250, F500, F1000 8.6. Timer function With the timer function the operating time can be limited to an allowed time. 8.6.1. Setting the time The setting can only be made in the Stop status. 1. Factory setting is the max. adjustable time: Calling the timer function: Hold the key pressed and activate the edit key shortly. The time which was set last, is shown. 2. Setting the time: 33 h 19 min. Activate key to set a higher value. Activate key to set a lower value.
Operating procedures 8.7. AUTOSTART ON / OFF The recirculating cooler 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). This safe operating state is indicated by „OFF“ on the LED temperature display. A complete shutdown of the main functional elements such as compressor and circulating pump is effected simultaneously.
F250, F500, F1000 9. Safety installations 9.1. Excess temperature protection + This safety installation is independent of the control circuit. When the temperature of the bath fluid has reached the safety temperature (85 °C), a complete shutdown of the compressor and pump is effected. The alarm is indicated by optical and audible signals (continuous tone) and on the LED-DISPLAY appears the error message "Error 14". Check the sizing of the application. You may have to use a more powerful chiller.
Troubleshooting guide / Error messages 10. Troubleshooting guide / Error messages + Whenever the microprocessor electronics registers a failure, a complete shutdown of the compressor 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 enter to quit the audible signal. • The recirculating cooler is operated without bath fluid, or the liquid level is insufficient.
F250, F500, F1000 • Switch off the unit • Wait for approx.2 seconds • Switch on the unit If the error occurs again, a remote diagnosis must be made.
