Any technical modification of the device by the user is prohibited. Any
damage resulting from unauthorized modification is not covered by customer
service or the product warranty. Service work may only be performed by the
LAUDA Service department or a service partner authorized by LAUDA.
All parts that come into contact with heat transfer liquid are manufac-
tured from high-quality materials adapted to withstand the operating tem-
perature. High-quality stainless steels, copper, brass and premium-quality
heat-resistant plastics are used.
Refrigeration process thermostats are operated with fluorinated refrigerants.
The designation and refrigerant charge are specified on the type plate.
Heat transfer liquids are used to control the temperature. LAUDA heat
n
transfer liquids are recommended for the constant temperature equip-
ment. LAUDA heat transfer liquids have been tested by the company
LAUDA DR. R. WOBSER GMBH & CO. KG and approved for this
device.
The heat transfer liquids are suitable for a specific temperature range.
n
This temperature range must correspond with the temperature range of
your application.
Hazards caused by high or low temperatures or fire may arise during
n
operation if the heat transfer liquid exceeds or falls below certain tem-
peratures or if the container ruptures causing a reaction with the heat
transfer liquid.
The safety data sheet of the heat transfer liquid specifies hazards and
n
the corresponding safety measures required for handling the liquid. The
safety data sheet of the heat transfer liquid must therefore be observed
to ensure proper use of the device.
