of such substances from the pump outlet, install an
appropriate collecting and disposal system and take
protective action for pump and environment.
➨
You must take suitable precautions to prevent any for-
mation of explosive mixtures in the pump chamber or
at the outlet of the pump. In case, e.g., of a diaphragm
failure, mechanically generated sparks, hot surfaces
or static electricity may ignite these mixtures. Use inert
gas for venting, if necessary.
➨
Drain appropriately or otherwise remove any poten-
tially explosive mixtures at the outlet of the pump, or
dilute them to non-explosive concentrations.
➨
Never operate this pump if it has a damaged cord or
plug.
+
If the pump is not working properly, has been dropped
or has fallen into water, contact your pump service pro-
vider.
+
Prevent any part of the human body from coming into
contact with vacuum.
+
Always provide a free and pressureless exhaust outlet
to avoid damage to pump valves and risk of bursting.
+
Attention : Due to clogging of the silencer an internal
overpressure may build up, which may damage bear-
ings, diaphragms and valves. Preferably use the hose
nozzle as outlet and make sure that the exhaust pipe-
line cannot become blocked.
+
Comply with applicable regulations when disposing of
chemicals. Take into consideration that chemicals may
be contaminated. Take adequate precautions to pro-
tect people from the effects of dangerous substances
(chemicals, thermal decomposition products of fluoro-
elastomers). Use appropriate protective clothing and
safety goggles.
