Safety / Storage and transport / Assembly and installation
• Risk of electric shock - This pump is supplied with a grounding
conductor and grounding-type attachment plug. To reduce the risk of
electric shock, be certain that it is connected only to a properly
grounding-type receptacle.
• Always depressurise liquid end before working on the pump.
• Always empty and rinse the liquid end before working on the pump
if used with hazardous or unknown feed chemicals.
• Wear safety equipment appropriate to the metering chemical when
working on the liquid end.
• Never let the pump work against a significantly increased operat
ing pressure or a closed stop tap on the discharge-side. This can
cause lines to burst.
• Avoid overfeed due to positive pressure difference between in take
and discharge sides. E.g. use a ball check valve with at least 1.5
bar opening pressure with an atmospheric pressure outlet (not 0213).
• Assembly and installation of ProMinent
original parts, which have not been checked and recommended by
ProMinent is not allowed and can lead to harm to persons or
property for which no liability can be accepted.
• Note all national directives which apply to the installation.
The sound pressure level is < 70 dB (A) at a distance of 1 m in accordance
with EN 23741 or EN 23742 at maximum stroke, maximum stroke rate, maxi-
mum back pressure (water)

Assembly and installation
IMPORTANT
• The pump must not vibrate when installed.
• Solenoid metering pumps tend to overfeed if the back pressure
is too low. In this case fit a ball check valve, a multifunction valve
or a discharge valve with 1.5 bar opening pressure downstream
from the pump (not 0213).
