Ensure that the equipment and all components are suit-
able for the intended application. Use the system only for
aspiration of liquids and ltration.
Setting up and installing the system
➨ Equipment must be connected only to a suitable elec-
trical supply and a suitable ground point. Failure to
connect the motor to ground may result in deadly elec-
trical shock.
The supply cable may be tted with a molded Euro-
pean IEC plug or a plug suitable for your local electri-
cal supply. If the plug has been removed or has to be
removed, the cable will contain wires color coded as
follows: green or green and yellow: earth; blue or white:
neutral; brown or black: live. The device has an internal
fuse.
+ Do not permit any uncontrolled pressurizing (e.g., make
sure that an exhaust tubing cannot become blocked).
Risk of bursting!
+ Due to the high compression ratio of the pumps, pres-
sure at the outlet port may be generated that is higher
than the maximum permissible pressure compatible
with the mechanical stability of the system.
+ Always provide a free and pressureless exhaust line.
• Comply with maximum permissible pressures and
pressure differences; see section ”Technical data”. Do
not operate the pumping unit with overpressure at the
inlet or outlet.
• Check that line voltage and current conform with the
equipment. (See rating plate.)
• Avoid overpressure of more than 0.2 bar in instances in
which inert gas is connected.
