The following questions shall help to recognize possible dangers and to reduce the risks to a minimum. • Are all tubes and electrical cables connected and installed? Note: sharp edges, hot surfaces in operation, moving machine parts, etc. • What to do when a dangerous substance was spilled on or in the unit? Before starting to work, obtain information concerning the substance and determine the method of decontamination.
Bath fluids Caution: 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.

7.7. 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“...
7.8. Remote control: activate – deactivate The recirculating cooler is to be prepared for remote control by a personal computer via the serial interface RS232. Set the interface item from >IOFF< to >ION<. Remote control: activate – deactivate: • Switch off recirculating cooler by pressing the mains switch and wait approx.
Safety installations 8.1. 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".
