Safety notes
CAUTION!
Warning of feed chemical spraying
around
An unsuitable feed chemical can
damage the parts of the pump con‐
tacted by the chemical.
– Take into account the resistance
of the materials which will come
into contact with the chemical
when selecting the feed chemical -
see the ProMinent Product Cata‐
logue or visit www.prominent.com.
CAUTION!
Warning of feed chemical spraying
around
Pumps which are not fully installed
hydraulically can pump feed chemical
from the outlet opening of the discharge
valve as soon as they are connected to
the mains power supply.
– First install the pump hydraulically,
then electrically.
– In the event that you have failed to
do so, press the On/Off switch (on
site) or the Emergency Stop
switch.

CAUTION!
Warning of feed chemical spraying
around
Feed chemical can spray out of the
hydraulic components if they are
manipulated or opened due to pressure
in the liquid end and adjacent parts of
the system.
– Disconnect the pump from the
mains power supply and ensure
that it cannot be switched on again
by unauthorised persons.
– Depressurise the system before
commencing any work on
hydraulic parts.
CAUTION!
Danger from rupturing hydraulic com‐
ponents
Peak loads during the dosing stroke
can cause the maximum permissible
operating pressure of the system and
pump to be exceeded.
– The discharge lines are to be
properly designed.
