Use only
original manufacturer’s spare parts and
accessories
. Otherwise the safety and performance of
the equipment, as well as the electromagnetic compat-
ibility of the equipment might be reduced.
The CE mark may be voided if not using original manu-
facturer’s spare parts.

Interruption of the pump (e.g., due to power failure),
failure of connected components or of parts of the sup-
ply, or change in parameters must not be allowed to
lead to dangerous conditions. In case of a diaphragm
failure or in case of a leak in the manifold, pumped sub-
stances might be released into the environment or into
the pump housing or motor.
Comply with all notes regarding proper use of the pumps,
as well as operation and maintenance guidance.

The residual
leak rate of the equipment
might render
possible an exchange of gas, albeit extremely slight,
between the environment and the vacuum system.
Adopt suitable measures to prevent contamination of
the pumped substances or the environment.
• Ensure that no parts of your clothing, hair or fingers can
be caught or drawn in at the inlet of the pump. Never
insert fingers or drop any other object into the inlet or
outlet.
•
Pay attention to the safety symbol ”hot surfaces” on
the equipment. Hot parts may cause burns if touched.
Adopt suitable measures to prevent any danger arising
from hot surfaces or electric sparks. Ensure that hot
surfaces of the pump do not cause burns. Provide a
suitable contact guard if necessary.
• Pumping at high inlet pressure may lead to overpres
-
sure at the gas ballast valve. Pumped gases or con-
densate might be expelled if the valve is open. If an
inert gas supply is connected to the gas ballast, ensure
that its inlet pipeline is not contaminated.
