Congratulations!
You have made an excellent choice.
JULABO thanks you for the trust you have placed in us.
This operating manual has been designed to help you gain an understanding of the operation and
possible applications of our circulators. For optimal utilization of all functions, we recommend that you
thoroughly study this manual prior to beginning operation.

Notice:
This abbreviated version does not release the user from the duty to instruct the operating
personnel on the work with this unit and particularly to point out to possible dangers.
For the general use in the laboratory the refrigerated and heating circulator F38-ME offers
a lot of setting possibilities, which are not necessary for doing a „Forcing Test“.
In the chapter „The easy way to the Forcing Test“ the advices for the necessary settings
are summarised.
Advices which are particularly important for doing a forcing test, are marked with
the symbol of a bottle (see left side).

Temperature control devices for research and industry are developed,
produced, and distributed according to the requirements of
ISO 9001:2008. Certificate Registration No. 01 100044846
Unpacking and inspecting
Unpack the circulator and accessories and inspect them for possible transport damage. Damage
should be reported to the responsible carrier, railway, or postal authority, and a damage report should
be requested. These instructions must be followed to the full extent for us to guarantee our full support
of your claim for protection against loss from concealed damage. The form required for filing such a
claim will be provided by the carrier

Operating manual
1. Intended use
JULABO circulators have been designed to control the temperature of specific fluids in a bath tank.
The JULABO forcing test refrigerated/heating circulating bath in connection with a photometer
determines the product life of beer without clouding.
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
1x10
PID3
ATC

RS232
Pt100
PUMP
SMART
The circulators are operated via the splash-proof keypad. The microprocessor
technology allows different values to be set, stored, and displayed on the VFD
COMFORT-DISPLAY. Three menu keys facilitate the adjustment of setpoints,
warning and safety functions, and menu functions.
Temperature- and time-dependent processes can be stored and executed using
the integrated programmer.
The adjustable PID cascade temperature control automatically adjusts the heat
supply to the thermal requirements of the bath.
Absolute Temperature Calibration (ATC3) provides high temperature stability at all
points 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 entire temperature range.
Electrical connections:
RS232 interface for modern process technology without an additional interface.
Connection for external Pt100 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 excess temperature protection according to IEC 61010-2-010 is a safety
device independent from the control circuit. Its safety value can be displayed and
adjusted on the VFD COMFORT-DISPLAY.
The early warning system for low level signals that bath fluid needs to be refilled
before the low level protection according to IEC 61010-2-010 triggers a safety
shutdown of the main functional elements.
Intelligent pump system: the pump capacity (electronically adjustable via the motor
speed) can be adapted to different conditions for internal and external temperature-
control applications.

Operator responsibility – Safety recommendations

2. Operator responsibility – Safety recommendations
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.
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:
You have received a product designed for industrial use. Nevertheless, 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
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 perform configuration, installation, maintenance and repairs of
the circulator.
Routine operation can also be carried out by untrained personnel who should however be instructed by
trained personnel.

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.
Only use recommended materials (bath fluids). Only use non-acid and non corroding materials.
When using hazardous materials or materials that could become hazardous, the operator must affix
the enclosed safety labels (1 + 2) to the front of the unit so they are highly visible:
1
Warning label W00: Colors: yellow, black
Danger area. Attention! Observe instructions.
(operating manual, safety data sheet)
2
or
Mandatory label M018: Colors: blue, white
Carefully read the user information prior to beginning operation.
Scope: EU
2
Semi S1-0701 Table A1-2 #9
Carefully read the user information prior to beginning operation.
Scope: USA, NAFTA
Particular care and attention is necessary because of the wide operating range.
There are thermal dangers: Burn, scald, hot steam, hot parts and surfaces that can be touched.
Warning label W26: Colors: yellow, black
Hot surface warning.
(The label is put on by JULABO)
Observe the instructions in the manuals for instruments of a different make that you connect to the
circulator, particularly the respective safety recommendations. Also observe the pin assignment of
plugs and technical specifications of the products.
2.1. Disposal
The circulator contains a back-up battery that supplies voltage to memory chips when the unit is
switched off. Do not dispose of the battery with household waste!
Depending on battery regulations in your country, you might be obliged to give back used or defect
batteries to gathering places.
The product may be used with oil as bath fluid. These oils fully or partially consist of mineral oil or
synthetic oil. For disposal, observe the instructions in the safety data sheets.
These units contains refrigerants– at this time considered not to have any negative effects on the
ozone layer. However, during the long operating period of the unit, disposal prescriptions may change.
So only qualified personnel should take care of disposal.
