☞
Obey
maximum permitted pressures
and pressure differences, see section ”Tech-
nical data”. Do not operate the pump with overpressure at the inlet.
Do not permit any
uncontrolled pressurizing
(e. g. make sure that the exhaust pipe-
line cannot become blocked). If you have an exhaust-isolation valve, make sure that
you cannot operate the equipment with the valve closed.
Risk of bursting!
☞
Ensure that the system design does not allow the exhaust pipeline to become
blocked.
☞
Max.
permitted pressure at the pressure transducer:
2 bar (absolute).
☞
Ensure that the system design does not allow the coolant outlet pipeline to become
blocked.
☞
Check the overpressure safety relief device at the exhaust waste vapour condenser
in appropriate intervals.
☞
Avoid overpressure of more than 0.2 bar in case inert gas is connected.
☞
The diameter of the inlet and outlet pipeline should be at the least as large as the
diameter of the pump connection pipelines.
To the best of our knowledge the equipment is in compliance with the requirements of
the applicable EC-directives and harmonized standards (see “Declaration of conform-
ity”) with regard to design, type and model, especially directive IEC 1010. This direc-
tive gives in detail conditions, under which the equipment can be operated safely (see
also IP degree of protection).
☞
Adopt suitable measures in case of differences, e. g. using the equipment out-
doors, installation in altitudes of more than 1000 m above mean sea level, conduc-
tive pollution or dewiness.
Pay attention to symbol “hot surfaces“ on the equipment (according to IEC 1010 rec-
ommendation).
☞
Adopt suitable measures to prevent any danger arising from the formation of hot
surfaces or electric sparks.
The pumps are
not suitable
to pump
dangerous or explosive gases or
explosive
or flammable mixtures.
Ensure that the materials of the wetted parts are compatible
with the pumped substances, see section “Technical data”.
☞
Adopt suitable measures to prevent the release of dangerous, explosive, corrosive
or polluting fluids.
☞
Use inert gas for gas ballast or venting if necessary.
☞
The user must take suitable precautions to prevent any formation of explosive
mixtures in the expansion chamber. In case of a diaphragm crack, mechanically
generated sparks, hot surfaces or static electricity may ignite these mixtures.
☞
Take adequate precautions to protect people from the effects of dangerous sub-
stances (chemicals, thermal decomposition products of fluoroelastomers), wear
appropriate safety-clothing and safety glasses.
☞
Obey applicable regulations when disposing of chemicals. Take into consideration
that chemicals may be polluted.
The motor is shut down by a
thermal cutout
in the winding.
☞
Manual reset is necessary. Switch off the pump or isolate the equipment from mains.
Wait approx. five minutes before restarting the pump.
☞
Provide a firm level platform for the equipment and check that the system to be
evacuated is mechanically stable and that all fittings are secure.
Attention:
Flexible elements tend to shrink when evacuated.
Due to the high compression ratio of the pumps, pressure at the outlet port might be
generated being higher than the max. permitted pressure compatible with the mechani-
cal stability of the system.
