manual. The non-observance of the instructions contained herein or improper use may involve
damages/injuries that are not covered by product liability.
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 outlet. It is the user’s responsibility to assure a proper
ground connection is provided.
Observe all warning labels and never remove therm.
Never operate damaged or leaking equipment.
Never operate the unit without fluid in the bath.
Never operate equipment with damaged power cords.
Pay attention to the thermal expansion of bath fluid during heating to avoid the risk of
overflowing.
Use suitable connecting tubes. Make sure that the tubes are securely attached.
Take care before drain the liquid out, be sure to cool it down below 40℃.
Always turn off the unit and disconnect the power cord from the plug source before performing

Electrical safety
The instrument has to 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, in order
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 would be 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 instrument is an instrument for organic chemical sample pretreatment. 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 vapors affecting operators’ health. If there is a fault,
please contact the Labtech Service Team.

4. TROUBLESHOOTING
The Pump Does Not Start After Switching The Power On
Check the power cord and ensure it is plugged in.
Check whether or not the system has higher negative pressure. This can be judged from the
vacuum gauge. If negative the pressure is bigger than -0.05MPa the pump cannot start. The
pump will work again as long as release the atmospheric pressure inside the system and back
to regular level.
The Pressure Declines Rapidly
Check whether or not the liquid, volatile solvent vapours or particles are inhaled into the pump.
If so, please pull out the ”IN” connection pipe and then switch the power on, and make pump
working without loading for about 10 minutes to dry up or blow out the impurities inside the
pump.
