1 Safety
1.1 General safety instructions
nThe devices must only be operated for the intended purpose
under the conditions stated in this operating manual. Any other
operating mode is considered to be non-intended use and can
impair the protection provided by the device.
nThe devices are not designed for use under medical conditions
in accordance with DIN EN 60601-1 or IEC 601-1!
nThe operating manual is a constituent part of the device. The
information in this operating manual must therefore be avail-
able in the immediate vicinity of the device. Also take care to
keep this copy of the operating manual.
If you lose this operating manual, contact the LAUDA
Constant Temperature Equipment service department.
The contact details can be found in Ä Chapter 13.4
‘LAUDA contact’ on page 102.
Use of the device results in hazards from high and low tempera-
tures and from the use of electrical energy. The hazards arising
from the device have been eliminated as far as possible by the
design in accordance with the applicable standards. Residual haz-
ards are reduced using any of the following measures:
nIf relevant, there are safety fittings for the device. These
devices are essential for the safety of the device. Their func-
tionality must be ensured by carrying out the appropriate main-
tenance activities.
The safety fittings of the device are described in this "Safety"
chapter.
nIf relevant, there are warning symbols on the device. These
symbols must always be observed.
The warning symbols on the device are described in this
“Safety” chapter.
nThere are safety instructions in this operating manual. These
instructions must always be observed.
nThere are additional specific requirements for the staff and for
the personal protective equipment.
These requirements are described in this "Safety" chapter.
An overview of the authorised personnel and the protec-
tive equipment can be found in Ä Chapter 1.12 ‘Per-
sonnel qualification’ on page 10 and Ä Chapter 1.13
‘Personal protective equipment’ on page 11.
Further information about the general structure of safety
instructions can be found in Ä Chapter 1.15 ‘Structure
of warnings’ on page 11.

1.2 Take note of additional operating instructions
The device can be equipped with additional interface modules.
Installation and use of interface modules requires that the respec-
tive operating instructions of the interface module are read and
adhered to.
1.3 Intended Use
The present device is exclusively permitted to be used for tem-
pering and delivering non-flammable heat transfer liquids in a
closed circuit.
The following applications are considered to be non-intended:
nin potentially explosive areas
nfor tempering foodstuffs
nwith a glass reactor without overpressure protection
1.4 Foreseeable misuse
Misuse of the device must always be prevented.
Among other things, the following uses are considered to be fore-
seeable misuse:
nOperation of the device without heat transfer liquid
nIncorrect connection of hoses
nSetting the device up on a tabletop surface
nSetting an incorrect pump pressure

1.7 No modifications may be made to the device
Any modification of the device by the user is prohibited. The conse-
quences of any such modifications are not covered by the product
warranty or customer service. Service work is only permitted to be
carried out by the LAUDA Constant Temperature Equipment
service department or one of the service partners authorised by
LAUDA.
1.8 Requirements for the heat transfer liquid
nHeat transfer liquids are used for temperature control. Only
LAUDA heat transfer liquids are approved for use in the device.
LAUDA heat transfer liquids are tested and approved by
LAUDA DR. R. WOBSER GMBH & CO. KG
nIn each case, the heat transfer liquids cover a specific tem-
perature range. This temperature range must match the tem-
perature range of your application.
nThe use of heat transfer liquids can cause hazards arising from
high and low temperatures, and fire, if certain temperature
thresholds are exceeded or if the temperature falls below the
threshold value, or if the container breaks and there is a reac-
tion with the heat transfer liquid.
nThe safety data sheet specifies the hazards and appropriate
safety measures for handling the heat transfer liquid. The
safety data sheet of the heat transfer liquid must therefore be
consulted for the intended use of the device.
Safety
Variocool 9
1.9 Materials
All parts coming into contact with the heat transfer liquid are made
of high quality materials suitable for the operating temperature.
High-quality stainless steel, copper, brass and temperature-
resistant plastics are used.
1.10 Requirements regarding the hoses
Only LAUDA hoses must be used for the external hydraulic circuit.
LAUDA hoses are hoses approved by LAUDA DR.
R. WOBSER GMBH & CO. KG. Particular attention must be paid to
the permissible temperature range and the maximum permissible
pressure when selecting suitable hoses for the application.
1.11 Application area
The device is exclusively permitted to be used in the following
areas:
nCommercial area
nIndoor use
Outdoor installation is also possible with appropriate equip-
ment.
nAmbient temperature range from 5 to 40 °C
Ambient temperature range with outdoor installation from -20 to
40 °C
nMaximum relative air humidity 80% for temperatures up to
31 °C, decreasing linearly to 50% relative air humidity at 40 °C
nAltitude up to a maximum of 2,000 m above sea level
nMains voltage fluctuations up to ± 10% of the rated voltage
nOvervoltage category II
nContamination level 2
nStorage temperature range from 5 to 40 °C
nTransport temperature range from -20 to 43 °C
1.12 Personnel qualification
Operating personnel
Operating personnel are personnel who have been instructed by
specialist personnel about the intended use of the device
according to the operating manual.
Specialist
Specific activities on the device must be carried out by technical
staff. Technical staff is personnel that can evaluate functions and
risks of the device and the application based on their training, skills
and experience.
