Congratulations!
You have made an excellent choice.
JULABO thanks you for the trust you have placed in us.
This operating manual has been designed to help you gain an understanding of the operation and
possible applications of our circulators. For optimal utilization of all functions, we recommend that you
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 recirculating cooler and accessories and check for damages
incurred during transit. These should be reported to the responsible carrier,
railway, or postal authority, and a request for a damage report should be
made. These instructions must be followed fully for us to guarantee our full
support of your claim for protecting against loss from concealed damage. The
form required for filing such a claim will be provided by the carrier.

1. Intended use
JULABO recirculating coolers have been designed for temperature application to specific fluids. The
pump connections can be used for cooling applications in an external circuit at a constant temperature.
JULABO water baths 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
PID1
RS232

The recirculating coolers are operated via the splash-proof keypad. The
implemented microprocessor technology allows to set and to store the setpoint that
can be indicated on the LED temperature display.
The PID temperature regulation is used to withdraw heat from the bath fluid by
means of the cooling machine and to automatically regulate the required need.
Electrical connections:
1. The serial interface RS232 allows modern process technology without
additional interface.
2. Alarm output for external alarm message.
Manually adjustable by-pass (handwheel) to reduce the pump capacity
(e. g. for glass equipment).
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 unit may be
operated only by persons who are absolutely familiar with these materials and the unit. 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 recommendations for the operator
You received a product conceived for industrial use. Nevertheless, avoid strikes to the housing,
vibrations, damages to the keypad foil (keys, display) or contamination.
Make sure the product is regularly checked for proper condition. Regularly check (at least every
2 years) the proper condition of the mandatory, warning, prohibition and safety labels.
Take care that the mains supply features a low impedance to avoid any negative affects on the
instrument being operated in 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 influence other units with components susceptible to magnetic fields (e.g. a
monitor). We recommend to keep a minimum distance of 1 m.
Permissible ambient temperature: max. 40 °C, min. 5 °C.
Permissible relative air humidity: 50 % (40 °C).
Do not store in an aggressive atmosphere. Protect from contaminations.
Do not expose to sunlight.
Appropriate Operation
Only qualified personnel is authorized to perform configuration, installation, maintenance and repairs
of the water bath.
Routine operation can also be carried out by untrained personnel who should however be instructed
by trained personnel.
Use
For the use according to the intended purpose, special material requirements have to be respected
(bath fluids). Only use non-acid and non corroding materials.
Observe all warnings for the used materials (bath fluids) and the respective instructions (safety data
sheets).
Only use the unit in well ventilated areas. (see page 15).
The recirculating coolers are not for use in explosive atmosphere
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 USA, 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 corresponding safety instructions. Also observe the pin assignment of plugs
and technical specifications of the products.
2.1. Disposal
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.

Notice:
Danger of corrosion of heat exchanger due to unsuitable quality of cooling
water.
•Due to its high content of lime hart water is not suitable for cooling and causes
calcination of the heat exchanger.
•Ferrous water or water containing ferrous particles will cause formation of rust
even in heat exchangers made of stainless steel.
•Chlorous water will cause pitting corrosion in heat exchangers made of stainless
steel.
•Due to its corrosive characteristics distilled and deionized water is unsuitable and
will cause corrosion of the bath. .
•Due to its corrosive characteristics sea water is not suitable.
•Due to its microbiological (bacteria) components which settle in the heat
exchanger untreated and unpurified river water and water from cooling towers is
unsuitable.
•Avoid particulate matter in cooling water.
•Avoid putrid water.
