1.1 Notes on Safety
WARNING
• Immediately switch off the pump in the case of emergency!
Use the pump power switch or an emergency stop switch in your working environment!
• When installing the metering pump also observe the installation instructions for
devices in explosive areas; for Europe the European operator directive 99/92/EC
(ATEX137) and the ATEX Product Directive 94/9/EC (ATEX 95), implemented in Germany
by the new health and safety legislation!
• When using the metering pump for metering flammable media, observe (in Europe) the
European Operator Guideline 99/92/EC (ATEX 137, previously ATEX118a), implemented
in Germany with the new operating safety directive and the German dangerous
chemicals directive.
• Observe also all relevant standards e.g. DIN EN 60079-10/14 and DIN VDE 60079-11 for
installations in explosion-threatened areas and DIN VDE 0118 for the installation of
electrical equipment in explosion-threatened areas by day.
• Note all national directives which apply to the installation when installing outside
Germany.
CAUTION
• Pumps must be accessible at all times to facilitate operation and maintenance.
Do not obstruct or block access routes!
• Only specially trained and authorized persons are permitted to maintain and repair
metering pumps and their peripheral equipment!
• Always depressurize the liquid end first before carrying out any work on the pump!
• If hazardous or unknown metering media are used, discharge and flush the liquid end
before carrying out any work on the pump!
• Observe the safety data sheets of the metering liquids!
• Always wear protective clothing (goggles, gloves) when handling hazardous or
unknown liquids! This applies in particular to working on the liquid end!
• Assembly of ProMinent
®
metering pumps with parts not tested and approved by
ProMinent is prohibited and can result in damage to persons and property, for which
no liability will be accepted!
IMPORTANT
• Adjust the stroke length only with the pump running when the load on the stroke length
setting pin is relieved temporarily!
Release the lock before adjusting the stroke length!
• Only use clamping rings and hose sockets suitable for the relevant hose diameter as
well as genuine ProMinent hoses with the specified hose dimensions and wall
thickness, otherwise the stability of the connection cannot be guaranteed!
NOTE
•Avoid reducing the hose sizes!
• Use the next higher pipe cross-section or a pulsation damper for long hose lines and
media with higher viscosity!
