Vetter Permanent aspirator - Manual (Page 5)

Page 5/20
Acids, caustic solutions and aggressively
acting solvents can form mixtures which
are a danger to health and therefore
must not be aspirated.
Dust cannot be aspirated with the Vetter Permanent Aspirator. In
agreement with the Trade Association we would like to expressi-
vely point out that in this connection, this aspirator must not be
used for the aspiration of dust and dust which is hazardous to
health.
3. Preparing the product for use
3.1 Preparations for operation
Place the container into the trolley if there is a trolley available for
mobile operation. When using the adapter make certain that the
adapter sealing on edge of the container seals correctly. Use the
filter cage when aspirating.
Connect the pressure coupling (Storz C) to the blocking valve. It is
to be opened before pumping begins and closed when pumping
has finished. This stops the pumped liquid from flowing back after
pumping has finished.
In order to pump out, connect a normal fire service hose having a
Storz C coupling to the blocking valve Size C. Lay out the hose so
that it is not bent. The fire service hose should not be longer than
necessary to achieve maximum pump performance. Check to see
if the motor head is perfectly seated in the adapter opening.
Connect the suction hose to the suction coupling for suctioning
off. Connect the bent pipe first and then connect the 2-part suc-
tion pipe to the previously mounted suction hose. Depending
on the type of use, push the ground nozzle or the narrow crevice
nozzle onto the suction pipe.
Connect the mains power plug to a
correctly installed protection contact socket.
3.2 Emergency switch
The Permanent Aspirator is equipped with an emergency switch
according the regulations from the German Association for Elec-
trical Engineering (VDE). If the emergency switch is activated be-
fore work begins then it can be deactivated by turning in the di-
rection of the arrow (clockwise).
