Preface
In order to make the equipment fully functional and ensure safety of the equipment, property,
specimens and the operator, read this manual carefully and completely. When you have any
question that cannot be explained by this manual, consult your local MRC distributors or
supporting technicians at MRC. It is our pleasure to provide services for you.
General safety notes
The equipment is designed for operation with non-flammable heat transfer liquids only!
No silicone oil is allowed for use with this series of the equipment. The internal silicone rubber parts
may swell when in contact with silicone oil resulting in leakage of the liquid! For engineering
change related to the use of silicone oil or other liquid, consult MRC engineer!
The equipment is intended for heating, cooling, conditioning of specimen and/or applications system
by immersion in or external circulating of the liquids. This leads to potential hazards of high or low
temperatures, fire, and the general hazards related to the application of electrical energy.
The operator is largely protected through the application of the appropriate standard specifications.
Further hazard sources may arise from the type of material being treated, e.g. mixing, dissolving,
reacting and resultant excessive energy, liquid spillage resulting from immersion or removal of
the specimen, and by the fracture or rollover of the container and reaction with the heat transfer
liquid.
It is not possible to cover all possibilities; they remain largely within the responsibility and the
judgment of the operator!
The equipment must only be used as intended and described in these Operating Instructions. This
includes operation by suitably trained qualified personnel.
The maximum temperature deviation both in normal condition and in electro-magnetic interference
field according to IEC 61326-1 is ±0.2 °C.
