The rotary-vane pump U34000 is in accordance with
the following applicable European directives and
standards:
89/336/EEC Electromagnetic Compatibility
73/23/EEC Low Voltage Directive
EMC: EN55014-1 (2000) + A2 (2002), EN55014-2 (1997)
+ A1 (2001)
LVD: EN60034-1 (1998) + A11 (2002)
Safe operation of the pump is guaranteed, provided it
is used correctly. However, there is no guarantee of
safety if the equipment is used in an improper or
careless manner.
The pump may only be used for its intended use. Any
other use is to be considered improper.
The manufacturer cannot be held responsible for
damages caused by improper use of the pump.
Under no circumstance must the pump be altered or
tampered with.
In case of tempering the manufacturer declines any
responsibility for the functioning and safety of the
pump.
If it may be assumed for any reason that non-
hazardous operation will not be possible (e.g. visible
damage), the pump should be switched off immedi-
ately and secured against any unintended use.
In schools and other educational institutions, the
operation of the pump must be supervised by quali-
fied personnel.
•
Before setting up and using the pump for the first
time, read the manual carefully.
•
Confirm that the voltage selector switch is set to
the local mains voltage.
•
The pump may only be connected to the mains
via a socket that has an earth connection.
•
The pump may only be opened/repaired by quali-
fied and trained personnel. Always disconnect the
pump by pulling the mains plug before proceed-
ing to any of the mentioned operations.
•
In case of power failure during operation, turn
the pump off for safety reasons.
