Information about the used refrigerants
The Regulation (EU) No. 517/2014 on fluorinated greenhouse gases applies to all
systems which contain fluorinated refrigerants and replaces (EC) 842/2006.
The aim of the Regulation is to protect the environment by reducing emissions of fluorinated
greenhouse gases.
Among other things it regulates the emission limits, use and recovery of these substances. It
also contains requirements for operators of systems which require / contain these
substances to function.
Under Regulation 517/2014, the operator of a system of this nature has the following duties:
•The operator must ensure that the equipment is checked at regular intervals for leaks.
•These intervals depend on the CO2equivalent of the system. This is calculated from
the refrigerant fill volume and type of refrigerant. The CO2equivalent of your system is
shown on the model plate.
•The operator undertakes to have maintenance, repair, service, recovery and recycling
work carried out by certified personnel who have been authorized by JULABO.
•All such work must be documented. The operator must keep records and archive them
for at least five years. The records must be submitted to the relevant authority on
request.
Refer to the text of the Regulation for further information.

4.3. Safety instructions
Follow the safety instructions to avoid personal injury and property damage. Also,
the valid safety instructions for workplaces must be followed.
•Only connect the unit to a power socket with an 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 unit on an even surface on a base made of nonflammable
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.
•Do not touch the immersion probe if it is frosted.
•Do not bend the tube connection of the immersion probe
•Keep the air intake and exhaust grids free of obstructions. (Maintain a
sufficient distance from all surrounding surfaces!)
•Do not move the unit from the position where it was set up during
operation.
•Always turn off the unit and disconnect the mains cable from the power
source 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.
•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 units with damaged mains power cables.
•Repairs are to be carried out only by qualified service personnel.
•There are thermal dangers: Touchable parts of the probe can be very
cold. Therefore, exercise particular caution when touching these parts.
Use gloves.

5. Preparations
5.1. Installation
•Place the unit on an even surface on a pad made of non-
flammable material.
•Press down the castor levers on model FT900.
•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.
•The ambient temperature must not exceed 35 °C.
•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
Avoid touching the immersion probe if it is frosted.
DANGER OF INJURY. Use gloves.
Switch the unit on only if the probe is immersed into the bath fluid.
To prevent the immersion probe (A) from icing, it should be completely
immersed into the bath liquid (B).

6. OPERATING PROCEDURES
6.1. Power connection
Caution:
•Only connect the unit to a power socket with earthing contact (PE –
protective earth)!
•The power supply plug serves as safe disconnecting device from the line
and must be always easily accessible.
•Never operate equipment with damaged mains power cables.
•Regularly check the mains power cables for material defects (e.g. for
cracks).
•We disclaim all liability for damage caused by incorrect line voltages!
Make sure that the line voltage and frequency match the supply
voltage specified on the type plate.
Deviations of ±10 % are permissible.

6.2. Switching On
•The immersion cooler is turned on and off with the mains switch.
(1).
The control light in the switch will illuminate.
The immersion probe – as part of the cooling circuit – should not be exposed
to bath temperatures above the working temperature of the immersion cooler.
This would cause damage to the compressor.
Do not immerse a frosted immersion probe into hot bath oil.

TROUBLESHOOTING
22
7. TROUBLESHOOTING
•Malfunction of compressor:
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
Caution:
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.
Prevent humidity from entering into the immersion cooler.
FT 400
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).

FT900
•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
from insufficient packing.
