thoroughly study this manual prior to beginning operation.
The JULABO Quality Management System
Temperature control devices for research and industry are developed,
produced, and distributed according to the requirements of ISO 9001 and
ISO 14001. Certificate Registration No. 01 100044846
Unpacking and inspecting
Unpack the circulator and accessories and inspect them for possible transport damage. Damage
should be reported to the responsible carrier, railway, or postal authority, and a damage report should
be requested. These instructions must be followed fully for us to guarantee our full support of your

Operating manual
1. Intended use
JULABO recirculating coolers have been designed to control the temperature of specific fluids in a
bath tank. The units feature pump connections for temperature control of external systems (loop
circuit).
JULABO recirculating coolers 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).
1.1. Description
PID2
ATC
3
RS232
PUMP
SMART
The recirculating coolers 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 MULTI-DISPLAY (LED). Three menu keys facilitate
adjusting setpoints, warning and safety functions and menu functions.
The PID temperature control adapts the heat supplied to the thermal requirements
of the bath.
Absolute Temperature Calibration (ATC3) provides a high temperature stability in
the bath. With the 3-point calibration an offset is adjusted at three temperatures to
ensure an accurate temperature pattern at the selected spot in the bath over the
full temperature range.
Electrical connections:
The serial interface RS232 allows modern process technology without additional
interface.
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 MULTI-DISPLAY (LED).
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.
The pump capacity (electronically adjustable via the motor speed) enables to adapt
to varying conditions for internal and external temperature applications.

2. Operator responsibility – Safety instructions
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 circulator 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 circulator 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 circulator.
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 might be chemical dangers depending on the bath medium used.
Observe all warnings for the used materials (bath fluids) and the respective instructions (safety data
sheets).
Insufficient ventilation may result in the formation of explosive mixtures. Only use the unit in well
ventilated areas.
Only use recommended materials (bath fluids). Only use non-acid and non corroding materials.
When using hazardous materials or materials that could become hazardous, the operator must affix
the enclosed safety 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.

(The label is put on by JULABO)
Observe the instructions in the manuals for instruments of a different make that you connect to the
circulator, particularly the corresponding safety instructions. Also observe the pin assignment of plugs
and technical specifications of the products.

2.1. Disposal
The recirculating cooler contains a back-up battery that supplies voltage to the memory chips when
the unit is switched off. Do not dispose of the battery with household waste!
Depending on battery regulations in your country, you may be obligated to return used or defective
batteries to collection sites.
The product may be used with oil as bath fluid. These oils fully or partially consist of mineral oil or
synthetic oil. For disposal, follow the instructions in the material safety data sheets.
This unit contains the refrigerant R404A, which at this time is not considered harmful to the ozone
layer. However, over the long operating period of the unit, disposal rules may change. Therefore, only
qualified personnel should handle the disposal.
