Operating manual
1. Intended use
JULABO circulators 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 circulators are not suitable for direct temperature control of foods, semiluxury 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
The circulators 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 VFD COMFORT-DISPLAY and LCD DIALOG-DISPLAY. Three
menu keys facilitate adjusting setpoints, warning and safety functions and menu
functions.
ICC
TCF
ATC
RS232
RS485

The integrated programmer allows storing and running temperature and time-
dependent processes.
The control electronics including “ICC - Intelligent Cascade Control“ automatically
adapts the heat supplied to the thermal requirements of the bath.
The TCF - Temperature Control Features allow the user to have access to all
important temperature control parameters. This means: Full control on the control
mode and the chance to manually adjust or adapt control to the specific application.
Absolute Temperature Calibration (ATC3) provides 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, switchable from RS232 to RS485, allows modern process
technology without additional interface.
Connection for Pt100 external sensor for external temperature measurement and
control.
Alarm output for external alarm message or control of JULABO refrigerating baths
or solenoid valve (cooling water).
The electronic module (option) provides 3 further analog connections (alarm input,
standby input, recorder output, programmer input).
SMART
PUMP
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 LCD DIALOG-DISPLAY.
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.
Intelligent pump system: The pump capacity (electronically adjustable via the motor
speed) enables to adapt to varying conditions for internal and external temperature
applications.

5.1. Installation
G½"
Place the unit on an even surface on a pad made of non-flammable
material. Using the castors move the unit to the intended location.
For better stability, apply the holding breaks on the front casters.
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: 40 °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 refrigerant quantity is specified on the type plate.
> For 0.52 kg of refrigerant R-404A, 1 m
> For 0.68 kg of refrigerant R-23, 1 m
> For 0.2 kg of refrigerant R-508b, 1 m

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.
Only for water-cooled models
:
Ensure circulation of cooling water by connecting the tubing to the cooling
water inlet and outlet at the rear of the refrigerated circulator.
Cooling water connections: G½"
Important: For cooling water, see page 14
5.2. Bath fluids
Caution:
Carefully read the safety data sheet of the bath fluid used, particularly with regard to
the fire point!
If a bath fluid with a fire point of 65 °C is used, only supervised operation is possible.
Water: The quality of water depends on local conditions.
Due to the high concentration of lime, hard water is not suitable for temperature
control because it leads to calcification in the bath.
Ferrous water can cause corrosion - even on stainless steel.
Chloric water can cause pitting corrosion.
Distilled and deionized water is unsuitable. Their special properties cause
corrosion in the bath, even in stainless steel.

The circulator is used for temperature application to external,
closed systems (loop circuit) with simultaneous temperature
application in the circulator bath.
Unscrew the M16x1 collar nuts on the pump connectors with a
19 mm (3/4“) wrench and remove the sealing disks. Using the
collar nuts, screw on the tubing connection fittings (for tubing
8 mm or 12 mm in diameter) delivered with the unit and tighten
firmly. (Pressure pump: 22, suction pump: 21)
Push on the tubing, and secure with tube clamps.
Attach the tubing to the connectors of the external closed
system, e.g., an instrument with a pressure-resistant
temperature jacket or a temperature coil, and fasten with tube
clamps to prevent slipping.
Temperature application to external, open systems
The circulator is equipped with both a pressure and suction pump
for external temperature application in open systems.
Differing flow rates of the pressure and suction pumps should be
compensated. To maintain a constant liquid level, the JULABO
„D+S“ Level Adapter is recommended for the external bath tank.
The flow rate of the pressure pump will be then regulated by a
built-in float device. The liquid level may be changed by a height
adjustment on the „D+S“ Level Adapter.
Accessory: „D+S“ Level Adapter Order No. 8 970 410
Important:
The liquid level should be equal in the internal and external

surrounding walls.
Regularly check the tubing for material defects (e.g. for cracks).
Preventive maintenance: Replace the tubing from time to time.
5.4. Filling / draining
Notice:
Pay attention to the thermal expansion of bath oil during heating to avoid
overflowing of the liquid.
Do not drain the bath fluid while it is hot!
Recommendation: Temperature range 5 °C to 40 °C
Check the temperature of the bath fluid prior to draining (by switching the unit on
for a short moment, for example).
Store and dispose the used bath fluid according to the laws for environmental
protection.
Filling
Take care that no liquid enters the interior of the circulator.
Recommended maximum filling level with water as bath fluid: 30 mm
below the tank rim
Recommended maximum filling level with bath oils:
40 mm below the tank rim
After filling, immerse the samples in the bath or place the lid on the
bath, in case the opening is not to be used.
The circulator provides an early warning system for low level
(description – please refer to page 33) that may be triggered when
changing samples in the bath.
Draining:
Turn off the unit and disconnect the mains cable from
the power source.
Hold the venting grid, pull out and remove.

Switching on:
Switch on the cooling machine using the switch (1b) .
Control of the cooling machine F81, F95, FW95:
With the mains switch (1b) turned on, the circulator automatically
switches the cooling machine off and on.
It is switched off if:
- the current working temperature is increased by > 30 °C (cooling is
not required).
- the heater operates at full power (> 800 W) for longer than 5
minutes.
It is switched on if:
- cooling is necessary to maintain the bath temperature.
After switch-off, the cooling machine automatically switches on only
after a delay of 5 minutes to protect the cooling compressor.
6.3. Start - Stop
To save energy, turn off the cooling machine with the mains switch
(1b) whenever cooling is not required.
Control of the FP89 cooling machine:
The mains switch is turned on. After pressing the start/stop button, the
cooling machine is automatically switched on or off by the circulator. In
the start mode of the circulator, the cooling machine runs continuously.
Immediately after starting the cooling machine, the output of the system
is reduced to a minimum value for a defined period in order to
equilibrate the cooling system. Afterwards the output of the cooling
machine is ramped up to the capacity required by the circulator.
A control of the capacity limitation subject to the temperature of the bath
is stored in the circulator. This is used to increase the operational
reliability and does not affect the maximum capacity of the cooling
machine.
