DANGER

Risk of dangerous gas mixtures during pump op-
eration

Depending on the medium being transferred,
breakage of the media-contacting components
can result in a dangerous mixture if the medium
mixes with the air in the compressor housing or
the surroundings.

à

Before using a medium, check the compati-
bility of the media-contacting components
(see 

4 Technical data

) with the medium.

7.1 Installing the pump

à

Store the pump at the installation site prior to installation to bring it up
to the ambient temperature.
