Operating manual
1. Intended use
JULABO Temperature Systems have been designed for temperature application to specific fluids in a closed
system (oop circuit). The units feature pump connections for temperature control of external systems (loop
circuit).
JULABO circulators are not suitable for direct temperature control of foods, semi-luxury foods and
tobacco, or pharmaceutical and medical products. Direct temperature control means unprotected
contact of the object with the bath medium (bath fluid).

PUMP
SMART
The Temperature Systems are operated via the splash-proof keypad. The implemented
microprocessor technology allows to set and to store different values that can be
indicated on the VFD COMFORT-DISPLAY and LCD DIALOG-DISPLAY.
The integrated programmer allows storing and running temperature and time-dependent
processes.
The control electronics including “ICC - Intelligent Cascade Control“ automatically adapts
the heat supplied to the thermal requirements of the bath.
The TCF - Temperature Control Features allow the user to have access to all important
temperature control parameters. This means: Full control on the control mode and the
chance to manually adjust or adapt control to the specific application.
Electrical connections:
The serial interface, switchable from RS232 to RS485, allows modern process technology
without additional interface.
The following analog sockets are available:
The REG+E-PROG socket for setpoint selection via an external, analog programmer.
At the same time, this socket provides three analog outputs for temperature recorders.
The external Pt100 socket for external control.
The alarm output for an external signal.
The stand-by input for external emergency switch-off.
The excess temperature protection conforming to IEC 61010-2-010 is a safety installation
independent from the control circuit. This protection can be indicated and set on the LCD
DIALOG-DISPLAY.
The early warning system for low level signals that bath fluid needs to be refilled before
the low level protection conforming to IEC 61010-2-010 causes a complete shut-down of
the main functional elements.
Intelligent pump system. The pump capacity (electronically adjustable via the motor
speed) enables to adapt to varying conditions for internal and external temperature
applications.

Operator responsibility – Safety recommendations

2. Operator responsibility – Safety recommendations
The products of JULABO ensure safe operation when installed, operated, and maintained according to common
safety regulations. This section explains the potential dangers that may arise when operating the temperature
system and also specifies the most important safety precautions to preclude these dangers as far as possible.
The operator is responsible for the qualification of the personnel operating the units.
The personnel operating the units should be regularly instructed about the dangers involved with their job
activities as well as measures to avert these dangers.
Make sure all persons tasked with operating, installing, and maintaining the unit have read and understand
the safety information and operating instructions.
When using hazardous materials or materials that could become hazardous, the temperature system may
be operated only by persons who are absolutely familiar with these materials and the circulator. These
persons must be fully aware of possible risks.
If you have any questions concerning the operation of your unit or the information in this manual, please contact
us!

Safety instructions for the operator:
Avoid strikes to the housing, vibrations, damage to the operating-element panel (keypad, display), and
contamination.
Make sure the product is checked for proper condition regularly (depending on the conditions of use).
Regularly check (at least every 2 years) the proper condition of the mandatory, warning, prohibition and
safety labels.
Make sure that the mains power supply has low impedance to avoid any negative effects on the instruments
being operated on the same mains.
This unit is designed for operation in a controlled electromagnetic environment. This means that transmitting
devices (e.g., cellular phones) should not be used in the immediate vicinity.
Magnetic radiation may affect other devices with components sensitive to magnetic fields (e.g., monitors).
We recommend maintaining a minimum distance of 1 m.
Permissible ambient temperature: max. 40 °C, min. 5 °C.
Permissible relative humidity: 50% (40 °C).
Do not store the unit in an aggressive atmosphere. Protect the unit from contamination.
Do not expose the unit to sunlight.
Appropriate operation
Only qualified personnel is authorized to configure, install, maintain, or repair the temperature system.
Persons who operate the circulator must be trained in the particular tasks by qualified personnel. The
summarized user guidance (short manual) and the specification table with information on individual parameters
are sufficient for this.
Use
The bath can be filled with flammable materials. Fire hazard! There may be chemical dangers depending on the
bath medium used. Observe all warnings for the materials (bath fluids) used and the corresponding instructions

Temperature System Magnum 91

(material safety data sheets).
Insufficient ventilation may result in the formation of explosive mixtures. Use the unit only in well ventilated areas.
Use only recommended materials (bath fluids). Use only nonacidic and noncorrosive bath fluids.
When using hazardous materials or materials that could become hazardous, the operator must affix the
enclosed warning labels to the front of the unit so they are highly visible:
If this unit is intended for use within the United States of America, all 3 warning labels must be affixed to the
housing of the unit prior to use. Directions for the positioning of the individual warning labels are enclosed with
the warning labels included in the delivery.
Warning labels must be easily visible to users.

Observe the instructions in the manuals for instruments of a different make that you connect to the circulator,
particularly the respective safety recommendations. Also observe the pin assignment of plugs and technical
specifications of the products.
2.1. Disposal
The product may be used with oil as bath fluid. These oils fully or partially consist of mineral oil or synthetic oil.
For disposal, observe the instructions in the safety data sheets.
Please observe the regulations for disposal which are effective in the country of operation.
This unit contains the refrigerants R404A and R23 – at this time considered not to have any negative effects on
the ozone layer. However, during the long operating period of the unit, disposal prescriptions may change. So
only qualified personnel should take care of disposal.
