Operating manual
JULABO immersion coolers are not suitable for direct temperature control of
with the bath medium (bath fluid).
Operating manual
1. Intended use
JULABO immersion coolers have been designed for temperature application to specific fluids
in a bath tank.
For example: Dewar vessels, beakers, or other containers in conjunction
with heating circulators for continuous countercooling
or for dry-ice substitution.
foods, semi-luxury foods and tobacco, or pharmaceutical and medical
products. Direct temperature control means unprotected contact of the object
1.1. Description
The JULABO immersion coolers FT200, FT 400 and FT900 are employed to cool liquids for
working temperatures ranging from +50 °C to -90 °C, such as in:
Dewar vessels, beakers, or other containers
in conjunction with heating circulators for continuous countercooling
or for dry-ice substitution.
The JULABO FD200 Flow-Through Cooler is employed to cool liquids in closed circuits. This
unit is generally installed at the intake of a heating circulator to draw heat away from the
circulating bath liquid.
Models FD200, FT200 and FT400 are provided with a handle for portable use.
Model FT900 is equipped with four castors. Two of the castors include locking levers that
should be pressed down after setting up the unit to prevent it from moving.
The immersion probe is connected to the instrument with a flexible, specially insulated tube.
On model FT900 the immersion probe is also flexible and may be adjusted precisely to
different positions within the vessel.
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.
4
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.

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, follow the instructions in the material safety data sheets.
This unit contains the refrigerants R134a R404A, and R-23, 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.

5.1. Installation
• Place the unit on an even surface on a pad made of non-

• The instrument should be set up at a frost-proof and dry location.
• 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.
> 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.
> For 0.68 kg of refrigerant R23, 1 m3 of space is required.
• Keep at least 20 cm of open space on the front and rear venting
grids.
• Do not set up the unit in the immediate vicinity of heat sources and
do not expose to sun light.
• Before operating the unit after transport, wait about one hour after
setting it up. This will allow any oil that has accumulated laterally
during transport to flow back down thus ensuring maximum cooling
performance of the compressor.
5.2. Immersion Probe
DANGER OF INJURY. Use gloves.
To prevent the immersion probe (A) from icing, it should be completely
immersed into the bath liquid (B).

OPERATING PROCEDURE S
Caution:
• We disclaim all liability for damage caused by incorrect line voltages!
Deviations of ±10 % are permissible.
• The immersion cooler is turned on and off with the mains switch.

7. TROUBLESHOOTING
• Malfunction of compressor:
Caution:
Prevent humidity from entering into the immersion cooler.
FT 400
The cooling compressor is equipped with an overload
protection device that will be triggered by overheating or
excessive current consumption. Possible causes include
insufficient ventilation or contamination of the condenser.
After a cool-down phase, the motor is automatically
switched on again.
• Interruption of the cooling loop (FD200) by a bended
tube.
8. Cleaning / repairing the unit
Before cleaning the unit, disconnect the power plug from the mains socket!
Always turn off the unit and disconnect the mains cable from the power source
before performing any service or maintenance procedures.
Service and repair work may be performed only by authorized electricians.
JULABO coolers are designed for continuous operation under
normal conditions.
Periodic maintenance is not required.
Regularly check the condensor for dirt contamination. Clean
the ribbed condensor, because dust and dirt will reduce
cooling performance of the unit.
Cleaning the Cooling Compressor:
• Switch off the unit, disconnect mains power cable.
Remove the hood (FD200, FT200, FT400).

from insufficient packing.
• The ventilation grid (7) is detached by unscrewing the four
mouting screws (FT900).
• Clean the ribbed condensor with a vacuum cleaner.
• Replace the hood or the ventilation grid.
• Switch on the unit.
Clean the outside of the unit using a wet cloth and low surface
tension water.
Repairs
Before asking for a service technician or returning a JULABO
instrument for repair, please contact an authorized JULABO
service station.
When returning the unit:
• Clean the unit in order to avoid any harm to the service
personnel.
• Attach a short fault description.
• During transport the unit has to stand upright. Mark the
packing correspondingly.
• When returning a unit, take care of careful and adequate
packing.
• JULABO is not responsible for damages that might occur
