Cryo-Compact Circulator Never operate the unit without bath fluid in the bath. Pay attention to the thermal expansion of bath oil during heating to avoid overflowing of the fluid. Prevent water from entering the hot bath oil. Do not drain the bath fluid while it is hot! Check the temperature of the bath fluid prior to draining (e.g., by switching the unit on for a short moment).

Preparations 5.2. Temperature application to external, closed systems The Cryo-Compact Circulator is used for temperature application to external, closed systems (loop circuit) Caution: Securely attach all tubing to prevent slipping. Notice: Flood hazard! If the liquid levels in the Cryo-Compact Circulator bath and the external system are at different heights, overflowing must be prevented after the power has been turned off.
Preventive maintenance: replace the tubing from time to time. Recommended tubing: Order No. Suitable for ® 8930008 1 m CR -tubing 8 mm inner dia. (-20 ... +120°C) CF30, CF40 ® 8930012 1 m CR -tubing 12 mm inner dia. (-20 ... +120°C) CF30, CF40 ® 8930108...
Fire or other dangers when using bath fluids that are not recommended: Please contact JULABO before using other than recommended bath liquids. JULABO assumes no liability for damage caused by the selection of an unsuitable bath fluid. Unsuitable bath fluids are fluids which, e.g.,...
Cryo-Compact Circulator Operating procedures 6.1. Power connection Caution: Only connect the unit to a power socket with an earthing contact (PE – protective earth)! The power supply plug serves as a safe disconnecting device from the line and must always be easily accessible. Never operate the unit with a damaged mains power cable.

Low level alarm is triggered at the following liquid level: CF30 75 to 80 mm below the tank rim CF40 80 to 85 mm below the tank rim When reaching the working temperature, check the liquid level. If the cooling coil is not completely covered with bath fluid, refill it.
DISPLAY and all indicator lights will illuminate (as illustrated on the left). Then the software version and the type of unit is indicated. Examples: (v 1.02) (CF30) The display "OFF" indicates the unit is ready to operate (standby mode).
AUTOSTART ON / OFF The Cryo-Compact 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). This safe operating state is indicated by „OFF“...
Cryo-Compact Circulator Warning: For supervised or unsupervised operation with the AUTOSTART function, avoid any hazardous situation to persons or property. The Cryo-compact circulator does no longer conform to N.A.M.U.R. recommendations. 6.7. Remote control: activate – deactivate The Cryo-Compact Circulator is to be prepared for remote control by a personal computer via the serial interface RS232.
Safety installations Safety installations Check the safety installations at least twice a year! (See page 16) 7.1. Excess temperature protection Warning: The excess temperature protection >SafeTemp< should be set below the flash point of the bath fluid used. In the event of wrong setting there is a fire hazard! We disclaim all liability for damage caused by incorreect settings! This safety installation is independent of the control circuit.
Cryo-Compact Circulator 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.

Cryo-Compact Circulator Electrical connections Notice: Use shielded cables only. The shield of the connecting cable is electrically connected to the plug housing. The unit ensures safe operation if connecting cables with a maximum length of 3 m are used. The use of longer cables does not affect proper performance of the unit, however external interferences may have a negative impact on safe operation.
Remote control 10. Remote control 10.1. Setup for remote control 1. Check the interface parameters for both interfaces (on Cryo- Compact Circulator and PC) and make sure they match. 2. Set the interface item from >IOFF< to >ION<. SERIAL 3. Connect both units with an interface cable. Interface parameters are pre-determined.
Cryo-Compact Circulator Important times for a command transmission: To ensure a safe data transfer, the time gap between two commands should be at least 250 ms. The Cryo-Compact Circulator automatically responds to an in command with a data string followed by a LF (Line Feed). The next command should only be sent after 10 ms.
Remote control IN commands: Asking for parameters or temperature values to be displayed. Command Parameter Response of recirculating cooler VERSION none Number of software version (V X.xx) STATUS none Status message, error message (see page 34 ) IN_PV_00 none Actual bath temperature. IN_PV_01 none Heating power being used (%).

JULABO Service – Online remote diagnosis 11. JULABO Service – Online remote diagnosis JULABO Cryo-compact circulator s of the HighTech series are equipped with a so-called black box. This box is implemented in the controller and records all significant data for the last 30 minutes.
Cryo-Compact Circulator 12. Draining Notice: Do not drain the bath fluid while it is hot! Check the temperature of the bath fluid prior to draining (by switching the unit on for a short moment, for example). Store and dispose the used bath fluid according to the laws for environmental protection.
Page 38
The Cryo-Compact Circulator is designed for continuous operation under normal conditions. Periodic maintenance is not required. The tank should be filled only with a bath fluid recommended by JULABO. To avoid contamination, it is essential to change the bath fluid from time to time.
