Safety Rules
General Information
Please carefully read this user manual before starting to use the instrument and follow its prescriptions with the
utmost care. This user manual is part of the delivery, hence must be always kept together with the instrument on
its working place.
It is imperative that every person operating with this system has read and fully understood this manual. The non-
observance of the instructions contained herein, or improper use may involve damages/injuries that are not covered
by product liability.
Electrical safety
The instrument must be used within the rated voltage. Prior to use, please check if the wire is aged. In case of
aged wires, please contact the after-sales service for inspection. It is forbidden to disassemble the instrument and
to connect internal circuit parts, to avoid a short circuit or open circuit.
Fire safety
Numerous reagents are flammable and explosive. When the solvent vapor concentration reaches a certain level, it
becomes flammable and could cause fire. The instrument should be kept away from the sources of ignition and
high temperature places. If there is solvent pungent smell, carefully check whether there is gas or liquid leakage,
and turn off the power.
Chemical safety
The unit is an instrument for organic chemical sample pre-treatment. The involved chemical solvents have harmful
effects on the human health. Despite the instrument is fully closed and features full vent design, it is recommended
to pay attention to the personal safety during the use. Regular check of liquid waste barrels as well as working
conditions of the vent fan are required to avoid the risk of leakage caused by corrosion and to avoid the formation
of organic solvent vapours affecting operator
’
s health. If there is a fault, please contact the after-sales service.
Recommendation
Never place the unit in a location where excessive heat, moisture, or corrosive materials are present.
The unit construction provides extra protection against the risk of electrical shock by grounding appropriate metal
parts. The extra protection may not function unless the power cord is connected to a properly grounded socket. It
is the user’s responsibility to assure that a proper ground connection is provided.
Never connect the inlet or outlet fitting to your building water supply or any water pressure source.
Never use flammable or corrosive fluids with this unit.
Do not use automotive antifreeze. Commercial antifreeze contains silicates that can damage the pump seals. Use
of automotive antifreeze will void the manufacturer’s warranty.
Transport the unit with care. Inclination angle must be less than 60 degrees otherwise the refrigeration system
could be damaged. Sudden jolts or drops can damage the refrigeration system.
Pay attention to all warning labels and never remove them.
