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.
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.

7
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

8
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 20).
The recirculating coolers are not for use in explosive atmosphere

9
When using hazardous materials or materials that could become hazardous, the operator must affix
the enclosed safety labels (1 + 2) to the front of the unit so they are highly visible:
1
Warning label W00: Colors: yellow, black
Danger area. Attention! Observe instructions.
(operating manual, safety data sheet)
2
or
Mandatory label M018: Colors: blue, white
Carefully read the user information prior to beginning operation.
Scope: EU
2
Semi S1-0701 Table A1-2 #9
Carefully read the user information prior to beginning operation.
Scope: USA, NAFTA
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 refrigerants R134a or R404A, which at this time are 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.
Valid in EU countries:
Directive 2002/96/EC of the European Parliament and of the Council of 27 January
2003 on waste electrical and electronic equipment (WEEE).
This directive requires electrical and electronic equipment marked with a
crossedout trash can to be disposed of separately in an environmentally friendly

4.3. Safety instructions
Follow the safety recommendations to prevent damage to persons or property.
Further, the valid safety instructions for working places must be followed.
Only connect the unit to a power socket with earthing contact (PE – protective
earth)!
The power supply plug serves as a safe disconnecting device from the line and
must always be easily accessible.
Place the instrument on an even surface on a pad made of non-inflammable
material.
Do not stay in the area below the unit.
Make sure you read and understand all instructions and safety precautions listed
in this manual before installing or operating your unit.
Never operate the unit without bath fluid in the bath.
Do not drain the bath fluid while it is hot or cold!
Check the temperature of the bath fluid prior to draining (by switching the unit on
for a short moment for example).
Use suitable connecting tubing.
Make sure that the tubing is securely attached.
Avoid sharp bends in the tubing, and maintain a sufficient distance from
surrounding walls.
Regularly check the tubing for material defects (e.g., for cracks).
Never operate damaged or leaking equipment.
Always turn off the unit and disconnect the mains cable from the power source

19
before performing any service or maintenance procedures, or before moving the
unit.
Always turn off the unit and disconnect the mains cable from the power source
before cleaning the unit.
Always empty the bath before moving the unit.
Transport the unit with care.
Sudden jolts or drops may cause damage in the interior of the unit.
Observe all warning labels.
Never remove warning labels.
Never operate equipment with damaged mains power cables.
Repairs are to be carried out only by qualified service personnel.
Risk of injury for hands. Close cover carefully.
Some parts of the bath tank and the pump connections may become extremely
cold during continuous operation. Therefore, exercise particular caution when
touching these parts.

20
5. Installation
Place the unit on an even surface on a base made of
nonflammable material.
Cooling machine, pump motor and electronics produce intrinsic
heat that is dissipated via the venting openings.! Never cover
these openings!
Keep at least 20 cm of open space on the front and rear venting
grids.
The place of installation should be large enough and provide
sufficient air ventilation to ensure the room does not warm up
excessively because of the heat the instrument rejects to the
environment. (Max. permissible ambient temperature: 35 °C).
For a fault (leakage) in the refrigeration system, the standard EN
378 prescribes a certain room space to be available for each kg
of refrigerant.
The necessary amount of refrigerant is specified on the type
plate.
> For 0.25 kg of refrigerant R134a, 1 m3 of space is required.
> For 0.52 kg of refrigerant R404A, 1 m3 of space is required.
