WARNING
• EX-pump only: when installing the metering pump, observe the directives for the
installation of devices in explosion-threatened areas, e.g. for Europe the European
operator's guideline 99/92/EC (ATEX 137)*, (in Germany implemented via the new
operating safety ordinance (Official Federal Gazette for 2002, Part 1, No. 70,
issued in Bonn 2.10.2002))!
* previously ElexV
• EX-pump only:
also observe relevant standards e.g. DIN EN 60079-10/14 and DIN EN 50020 for
installations in explosion-threatened areas!
• Note all national directives which apply to the installation!
IMPORTANT
• In order to check pressure conditions in the piping system, it is recommended to
provide connection facilities for pressure gauges in the vicinity of the intake and
delivery connection piece.
• Connect pipes to the pump such that there is no stress or strain whatsoever acting
on the pump, such as offset, weight or expansion of the pipe. Only use a flexible pipe
adapter for connecting steel/stainless steel pipes to plastic pump housings.
