2. SAFETY RULES
General Information
Please read carefully this user manual before starting the system 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 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
Most reagents used in the MULTIVAP 54 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 MULTIVAP 54 system 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.

Nitrogen channel method interface:
13
Activate the 6 nitrogen needle channels
according to specific needs.
There are 3 different status:
•gray = unselected
•blue = selected
•red = currently on process
If a channel is unselected, thr nitrogen
flow is automatically stopped
14
Light switch bottom:
•OFF
•ON
15
Run: the concentration method starts according the selected
parameters
Pause: the nitrogen blow function stops and nitrogen needles reset to
the initial position. The instrument can be opened and samples taken
out. Once the cover is closed, the nitrogen needles descend
automatically to the last position and the method restarts
Stop: all channels stop working and nitrogen needles reset to the initial
position. A single channel can be stopped
