1 Safety
1.1 General safety instructions
The equipment must only be operated for the intended use
under the conditions stated in this operating manual. Any other
type of operation is considered to be not-intended use and can
impair the protection provided by the device.
The operating manual is part of the device. The information in
this operating manual must therefore be available in close
vicinity to the device. Also store this copy of the operating
manual carefully.
If you lose this operating manual, contact the LAUDA
Constant Temperature Equipment service. The contact
details can be found in
Ä
Chapter 12.3 ‘LAUDA contact’
on page 63.
Use of the device results in hazards from high or low temperatures,
fire and from the use of electrical energy. The hazards of the
device must be eliminated as much as possible by the design in
accordance with the appropriate standards. Residual hazards are
reduced using any of the following measures:
If relevant, there are safety devices for the device. These
devices are essential for the safety of the device. Their func-
tionality must be ensured with appropriate maintenance activi-
ties.
The safety devices of the device are described in this "Safety"
chapter.
If relevant, there are warning symbols on the device. These
symbols must always be observed.
The warning symbols on the device are described in this
chapter “Safety”.
There are safety instructions in this operating manual. These
instructions must always be observed.
There are additional specific requirements for the personnel
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 1.9 ‘Per-
sonnel qualification’ on page 8 and
Ä
Chapter 1.10
‘Personal protective equipment’ on page 9.
Further information about the general structure of safety
instructions can be found in
Ä
Chapter 1.11 ‘Structure
of safety instructions’ on page 9.

1.2 Intended use
The present device is exclusively permitted to be used for tem-
pering and delivering non-combustible heat transfer liquids in a
closed circuit.
The following applications are considered to be not-intended:
medical applications
in potentially explosive areas
for tempering foodstuffs
with a glass reactor without overpressure protection
1.3 Foreseeable misuse
Misuse of the device must always be prevented.
Among other things, the following uses are considered to be fore-
seeable misuse:
Operation of the device without heat transfer liquid
Incorrect connection of hoses
Placement of the device on a tabletop surface, only permitted
for MC 600 and MC 1200 (W)
Setting an incorrect pump pressure
1.4 Modifications to the device
Any technical modifications to the machine are prohibited. Service
works may be carried out only by the LAUDA Constant Tem-
perature Devices service or one of the service partners authorized
by LAUDA.
1.5 Heat transfer liquid
The device is exclusively designed for nonflammable heat
transfer liquids in Class I according to DIN 12876-1.
Heat transfer liquids are used for the temperature control. Only
LAUDA heat transfer liquids are approved for the device.
LAUDA heat transfer liquids are heat transfer liquids that have
been tested and approved by the company LAUDA DR. R.
WOBSER GMBH & CO. KG.
Intended use
Non-intended use
Safety
Microcool 7

In each case, the heat transfer liquids cover a specific tem-
perature range. This temperature range must match the tem-
perature range of your application.
The use of heat transfer liquids can cause hazards from high or
low temperatures and fire if certain temperature thresholds are
exceeded or undercut or if the container breaks and there is a
reaction with the heat transfer liquid .
The heat transfer liquid safety data sheet specifies all possible
hazards and appropriate safety measures for handling the
liquid. The safety data sheet must therefore be consulted for
the intended use of the device.
1.6 Materials
All parts coming into contact with the heat transfer liquid are made
of high quality materials suitable for the operating temperature.
Stainless steel and temperature-resistant plastics are used.
1.7 Hoses
Only LAUDA hoses are permitted to be used for the external
hydraulics circuit. LAUDA hoses are hoses that are approved by
LAUDA DR. R. WOBSER GMBH & CO. KG. When selecting suit-
able hoses for the application, the permissible temperature range
and the maximum permissible pressure must be particularly
observed.
1.8 Application area
The device is exclusively permitted to be used in the following
areas.
Commercial area
Indoor use, no outdoor installation
Ambient temperatures from 5 to 40 °C
1.9 Personnel qualification
Operating personnel
Operating personnel are employees that have been instructed by
technical staff in the intended use of the device according to the
operating manual.

1.10 Personal protective equipment
Protective clothing
Protective clothing is required for certain activities. This protective
clothing must comply with the legal requirements for personal pro-
tective equipment. Protective clothing should have long sleeves.
Safety footwear is additionally required.
Protective gloves
CE protective gloves are required for certain activities. These pro-
tective gloves must comply with the legal requirements for personal
protective equipment of the European Union.
Protective goggles
Protective goggles are required for certain activities. These protec-
tive goggles must comply with the legal requirements for personal
protective equipment of the European Union.
1.11 Structure of safety instructions
A safety instruction of the type "Danger" indicates an immedi-
ately hazardous situation.
This results in death or severe, irreversible injuries if the
safety instruction is disregarded.
