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
PID1
RS232
;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.
;Safety installations conforming to IEC 61010-2-010
The excess temperature protection is a safety installation independent from
the control circuit.
The safety value is set using a tool (screwdriver).
If the low level protection device is triggered, a complete shutdown of the
heater and circulating pump is effected.
;The serial interface RS232 allows modern process technology without
additional interface.
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.

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:
xThe operator must ensure that the equipment is checked at regular intervals for leaks.
xThese 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.
xThe operator undertakes to have maintenance, repair, service, recovery and recycling
work carried out by certified personnel who have been authorized by JULABO.
xAll 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.

5. Preparations
5.1. Installation
xPlace the unit on an even surface on a base made of
nonflammable material.
xCooling machine, pump motor and electronics produce
intrinsic heat that is dissipated via the venting openings.!
Never cover these openings!
xBe sure that the flow of ventilation can exit under the
instrument.
xKeep at least 20 cm of open space on the side and rear of
the unit.
xThe 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.
> For 0.423 kg of refrigerant R452A, 1 m3 of space is
required.
xModel CF40 with 0.16 kg filling quantity of refrigerant
R404A = 0.33 m3volume
Model CF40 with 0.17 kg filling quantity of refrigerant
R452A = 0.40 m3volume
Model CF30 with 0.15 kg filling quantity of refrigerant R134a
= 0.6 m3volume
xDo not install the unit in the immediate vicinity of heat sources and do not
expose it to sunlight.
xBefore 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.
