Safety
Safety instructions
The unit is built in accordance with state of the art technology and recognized safety regulations. Despite this, its use may pose a risk to life and limb for the user or third parties.
Therefore, always read and observe the following safety instructions before using the product.
Hot surfaces!
The following parts and elements may become hot during operation:
- Bath fluid
- Heating element
- Bath lid
- Bath surface
- Connections for external application
Contact may cause severe burns or scalds to hands and arms, face and limbs.
- Keep sufficient distance from hot surfaces and fluids.
- Wear suitable protective gloves.
Electric shock from electrical system!
Touching damaged live parts can cause severe electric shocks and lead to injury or even death.
- Have damaged insulation and parts of the electrical system immediately repaired by JULABO service technicians or a qualified specialist workshop
- Immediately replace damaged power cords
- When connected with a mains plug, this mains plug must always be readily accessible.
Wear personal protective equipment!
Lacking or unsuitable personal protective equipment increases the risk of health damage and injury.
Personal protective equipment includes, for example:

Safety function
Technical protective devices provide for safe operation. If a safety function is triggered, the operator is alerted with a message on the display and an acoustic signal.
Overheating protection
The overheating protection prevents overheating of the heater.
- The protective mechanism is triggered when the device recognizes a temperature difference of more than 20 K between the working temperature sensor and the safety temperature sensor. Am error message appears on the display. A restart is required.
Low liquid level protection
A level switch recognizes when the bath fluid fill level in the bath tank is too low. The unit has a warning system to prevent overheating of the heater or dry running of the pump.
- The low liquid level alarm is triggered when the float reaches its lower limit stop. The device switches off the pump and heater. A continuous signal tone sounds. An error message appears on the display. A restart is required.

-
Press one of the arrow keys briefly.
The display switches from the actual value display to the setpoint display, then shows the last saved setpoint temperature. The digits before the decimal point flash. -
Use the arrow keys to set the value before the decimal point and confirm with [OK].
The set value is applied. The decimal point flashes. -
Use the arrow keys to set the value after the decimal point and confirm with [OK].
The set value is applied. The new setpoint temperature flashes briefly.
The setpoint temperature is set and active.
Start temperature control application
You can start a temperature control application right on the device, or program one using the timer.
The unit is ready for use.
- Switch the unit on at the mains switch.
- Use the arrow keys to set the desired setpoint temperature.
- Press and hold the [OK] key until the temperature control application starts.
The setpoint temperature is saved. The display flashes briefly. The unit starts the temperature control application at once. The temperature control application can be stopped with the [OK] key.
Observe the following for heating circulators:
For temperature control applications near or below the ambient temperature: Use a cooling coil or JULABO immersion cooler.
Activate autostart function
The autostart function makes it possible to start a temperature control application directly using the mains switch or via an intermediate timer. The device is configured ex works in such a ways that it switches to a safe operating status in the event of power failure. The autostart function is deactivated. The display shows “OFF.” The refrigeration aggregate, heater, and pump motor are disconnected from the mains voltage.
The unit is switched off.
The autostart function is deactivated.
Simultaneously press and hold the [OK] key and the power switch until the device is switched on.
The display shows .
The autostart function is activated. The temperature control application
starts immediately with the preset values, each time the device is switched
on, as long as the autostart function is active. To deactivate the autostart
function, switch off the device and repeat the procedure. The display will
then show
Setting the timer
The timer can be used to program the duration of a temperature control application from 0 to 999 minutes. The setpoint temperature is maintained for the programmed time. After the set duration has elapsed, the device switches to standby mode.
The unit is switched on.
-
Press the [Down Arrow] and [OK] keys simultaneously.
The display shows <t 0>. -
Use the arrow keys to set the minutes and confirm with [OK].
The display flashes briefly.
The timer is programmed and active
The decimal point flashes on the display until the timer starts. The timer starts when the setpoint temperature is reached and maintained, with a precision of ±0.1°K, for at least 30 seconds. Below 1 minute, the remaining run time is shown in seconds.
After the set time has elapsed, a double acoustic signal sounds and the device switches to standby mode.
The setpoint temperature can still be changed until it is reached. The timer remains active and starts when the new setpoint temperature is reached. If the setpoint temperature is changed while the timer is running, the timer is deactivated
Press the [OK] key to stop the running timer.
Adjusting the temperature sensor (ATC)
For physical reasons, there can be a temperature difference in the bath tank between the temperature sensor and a defined, more remote point within the bath fluid volume. As a result, the measured temperature deviates slightly from the actual bath temperature. Adjustment of the temperature sensor can increase accuracy of the temperature control application.
The bath tank is filled.
The unit is switched on
-
Hang the calibrated thermometer in the bath tank and place the bath lid on top.
-
Set the desired setpoint temperature and start the temperature control application.
When the setpoint is reached, allow the temperature to stabilize for several minutes.
The more stable the temperature in the bath tank, the more precise the adjustment result. -
Simultaneously press the Service key and [Down Arrow] keys until the decimal point flashes.
-
Enter the read reference temperature and confirm with [OK].
The calibration value is applied directly. The display shows for confirmation.
The entered reference temperature must be within ±5°C of the setpoint temperature, otherwise an error message appears and the entry is ignored.
The temperature sensor is adjusted.
