Use only genuine spare parts and accessories.
☞
Otherwise safety and performance of the equipment as well as the electromag-
netic compatibility of the equipment might be reduced.
☞
If not using genuine spare parts the ATEX conformity becomes invalid.
Do not start the pump if the pressure difference between inlet and outlet port ex-
ceeds 1.1 bar at maximum.
Prevent the backpressure of gases and the backflow of condensates.
Never suck liquids or dust into the pump.
Ensure that in case of failure the pump and the vacuum system always will turn into
a safe status.
Provide appropriate protective measures (i.e. precautions which allow for the re
-
quirements of the respective application) even for the case of failure and
malfunc-
tion
.
Comply especially with notes on operation and use and maintenance.
Due to the residual
leak rate of the equipment
, there might be 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.
Safety during operation
➨
In case install an appropriate collecting and disposal system and take protective
action for pump and environment.
➨
Potentially explosive mixtures at the outlet of the pump have to be drained ap
-
propriately, sucked off or diluted with inert gas to non-explosive mixtures.
☞
Pay attention to the symbol ”hot surfaces” on the equipment. Adopt suitable
measures to prevent any danger arising from the formation of hot surfaces or
electric sparks. Provide a suitable protection against contact if necessary.
☞
Check liquid level in both catchpots regularly and drain condensate in time.
• Comply with applicable regulations when disposing of chemicals. Take into con
-
sideration that chemicals may be polluted.
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.
