3 Intended use
This section defines the purpose of the unit so that the operator can operate the
unit safely and avoid misuse.
JULABO circulators are laboratory devices that are designed for temperature
control applications with liquid media in a bath tank or with a cooling machine.
An external loop circuit can be connected to the pump connectors so that the
temperature of the bath media can be kept constant.
Only use the device if it is in technically perfect condition and only use it in
accordance with its intended use. Be aware of safety issues or hazards and
comply with the operating manual! In particular, always immediately rectify
faults that could impair safety!
The circulators are not suitable for direct temperature control application of
food, other consumables or pharmaceutical or other medical products.
The devices are not suitable for use in an explosive environment.
The devices are not intended for use in living areas. They may cause interference
with radio reception.

4.2 General Safety Instructions for the operator
This section outlines the General Safety Instructions that must be observed by
the user to ensure safe operation.
• Read the operating manual before initial operation
• The device may only be connected to mains power outlets with a protective
earth (PE)
• The mains plug is a safe insulator of the power supply grid and must be
freely accessible at all times
• Do not start the device if it has a damaged power cable
• Do not operated damaged devices
• Only mount the circulator in suitable bath tanks or refrigeration units
• When connecting to external devices, observe the respective assembly
instructions, connection assignment of the plugs and technical data for the
products
• Observe the safety symbols on the device.

4.3 General Safety instructions for device operation
This section lists the General Safety Instructions for device operation. These
Safety Instructions must be followed to ensure safe operation.
• Vapors may escape during the temperature control application. Operate the
device in a well-ventilated location.
• Depending on the bath fluid, chemical dangers may occur. Observe
appropriate safety regulations
• If flammable substances are used in the bath and/or flammable bath fluid is
used, the device must be under constant observation during operation
• The safety functions of the device should be checked at least twice per year

4.4 Safety symbols
There are safety symbols included with the device, which should be attached to
the device before initial operation.

Read operating manual before switching on
4.5 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.
Adjustable high temperature cut-off
The high temperature cut-off prevents overheating of the heater.
• If the temperature of the working temperature reaches the set protective
temperature, an error message appears on the display. The pump and
heater are switched off. A restart is required.

Safety

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 device has a two-stage warming system to prevent overheating of the
heater or dry running of the pump.
• The low liquid level warning is triggered when the liquid level in the bath
tank is about half the full level. A warning message appears on the display.
The bath fluid should be topped up.
• 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. A warning message appears on the display. A restart is
required.

5.2 Function description
This section describes the function of the device.
The circulators are used for internal and external temperature control, and
depending on the device combination and accessories used can work in a
temperature range between -50 °C and +300 °C.
When mounted on a bath tank the circulator is a heating circulator, when
combined with a cooling machine it is a refrigerated circulator.

5.4.2 Stakei output
The Stakei output is a control output that can be adjusted to solenoid valves
with various tasks via the operating menu. The desired function is set and
activated in the operating menu.
The Stakei output can be assigned the following functions:
• Refill device:
The Stakei output switches on when a low liquid level warning is triggered.
If the level of the bath fluid drops below a certain level, the Stakei output
turns on and a connected refilling device can be activated. This pumps bath
fluid into the bath tank until the filling level has returned to a non-critical
level.
• Cooling pulse:
This function is controlled by the current cooling capacity of the device. If
the temperature setpoint is lower than the actual temperature detected by
the device, a pulse-width modulated signal is sent via the Stakei output.
This signal can be used to control a solenoid valve for cyclic counter-cooling
via a cooling coil.
• Backflow:
This function is used as backflow protection in a system where the
connected application is physically higher than the circulator. When the
pump is running, the Stakei output is switched on and a check valve
inserted between the circulator and the application can be controlled. This
prevents the bath fluid flowing from the application to the bath tank while
the pump is not running and causing the bath tank to overflow.
