WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious inju‐
ries.
Please ensure when handling hazardous sub‐
stances that you have read the latest safety data
sheets provided by the manufacture of the haz‐
ardous substance. The actions required are
described in the safety data sheet. Check the
safety data sheet regularly and replace, if neces‐
sary, as the hazard potential of a substance can be
re-evaluated at any time based on new findings.
The system operator is responsible for ensuring
that these safety data sheets are available and that
they are kept up to date, as well as for producing
an associated hazard assessment for the worksta‐
tions affected.
WARNING!
Dangerous reactions are possible due to contact of
feed chemical with water
The feed chemical can mix and react in the liquid
end with water remaining after testing in the fac‐
tory.
– Read the safety data sheet on the feed chem‐
ical.
– Blast the liquid end with compressed air.
– Flush the liquid end with a suitable medium
through the suction connector.
FDA pumps only: problems with hygiene are possible.
n
The pumps can become contaminated through packaging and
shipment.
n
Flush through before using the pumps.
CAUTION!
Warning of feed chemical spraying around
An unsuitable feed chemical may damage the
parts of the pump that come into contact with it.
– Take into account the resistance of the wetted
materials when selecting the feed chemical -
refer to the ProMinent Resistance List in the
Product Catalogue or at www.prominent.com.
n
Reliable metering cannot be guaranteed after the metering
pump has been idle for some time, as the feed chemical can
crystallise in the valves and on the diaphragm. Regularly check
the valves and diaphragm.
n
Only adjust the stroke length when the pump is running.
