Operating manual
1. Intended use
JULABO Cryo-Compact Circulators have been designed for temperature application to
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,
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
The Cryo-Compact Circulators 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 control adapts the heat supplied to the thermal
requirements of the bath.

Preparations
5. Preparations
5.1. 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!
Be sure that the flow of ventilation can exit under the
instrument.
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 refrigerant quantity is specified on the type plate.
> For 0.52 kg of refrigerant R404A, 1 m3 of space is
required.
> For 0.25 kg of refrigerant R134a, 1 m3 of space is
required.
Model CF40 with 0.16 kg filling quantity of refrigerant

Do not install the unit in the immediate vicinity of heat sources and do not
expose it to sunlight.
Before operating the unit after transport, wait about one hour after
installation. This will allow any oil that has accumulated laterally during
transport to flow back down, thus ensuring that the compressor can
develop its maximum capacity.

5.4. Bath fluids
Caution:
Carefully read the material 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 scale in the bath
Ferrous water can cause corrosion, even on stainless steel.
Chlorinated water can cause pitting corrosion.
Distilled water and deionized water are unsuitable. Their special
properties cause corrosion in the bath, even on stainless steel.

Never operate the unit with a damaged mains power cable.
Regularly check the mains power cables for damage.
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.
6.2. Filling
Notice:
Pay attention to the thermal expansion of bath oil during heating to avoid
overflowing of the liquid.
Guideline:
A volume change of 12 % per 100 °C temperature variation is to be
considered.
Take care that no liquid enters the interior of the Cryocompact circulator.
Connect the tubing from the external system to the pump
connectors and check for leaks.
Check to make sure that the drain tap (7) is closed.
Recommendation:
For filling, use for example an measuring jug with nuzzle.
20
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

Refill fluid.
The Cryo-Compact Circulator is ready for operation.
Important:
When using a bath fluid, the change in volume in case of change
in temperature has to be respected. Fill in a little amount of bath
fluid only so that the low level alarm is not triggered.
Low level alarm is triggered at the following liquid level:
CF30 75 to 80 mm below the tank rim
CF40 80 to 85 mm below the tank rim
When reaching the working temperature, check the liquid level. If
the cooling coil is not completely covered with bath fluid, refill it.

A transfer sequence consists of:
If the Cryo-Compact Circulator is put into remote control mode the
MULTI-DISPLAY (LED) will read „R -OFF-„ = REMOTE STOP. The
Cryo-Compact Circulator is now operated via the computer.
In general, the computer (master) sends commands to the
recirculating cooler (slave). The recirculating cooler sends data
(including error messages) only when the computer sends a query.
In remote control mode:
After a power interruption the order to start and all values which have
to be adjusted must be resent from the personal computer via the
interface. AUTOSTART is not possible.

Important times for a command transmission:
To ensure a safe data transfer, the time gap between two commands
should be at least 250 ms.
The Cryo-Compact Circulator automatically responds to an in
command with a data string followed by a LF (Line Feed). The next
command should only be sent after 10 ms.
The commands are divided into in or out commands.
in commands: asking for parameters to be displayed
out commands: setting parameters
The out commands are valid only in remote control mode.
Examples:
Command to set the working temperature to15,5 °C:

11. JULABO Service – Online remote diagnosis
Cryo-Compact Circulator
JULABO Cryo-compact circulator s of the HighTech series
are equipped with a so-called black box. This box is
implemented in the controller and records all significant data
for the last 30 minutes.
In case of a failure, this data can be read out from the unit by
using special software. The respective program is available
for free download from www.julabo.de \ EasyBlackBox.
Installation is easy and carried out step by step.
Please observe the instructions.
Data read-out is possible in the conditions
„OFF“, „R OFF“ or „ALARM“.
Connect the Cryo-compact circulator to the computer
using an interface cable.
Start the EasyBlackBox program.
The program asks for the used port (COM1, ......) and the
baud rate of the unit.
You do not have this information on hand? Simply try it
out!
The program keeps on sending this request until the
actually used port and correct baud rate are entered.
Data is read out and shown on the monitor
divided in the sections
>Einstellungen/Settings<,
>Alarmspeicher/Alarms stored<,
>Blackbox<
see example
After pressing >Speichern/Save< a text file
is compiled. The program proposes a
filename >C:\model description and barcode no.<.
Modifications are possible.
E-mail this file to service@julabo.de,
