Safety information
WARNING!
Fire hazard with flammable media
Only with flammable media: They can be ignited by
oxygen.
– The pump may not work if there is a mixture of feed
chemical with oxygen in the liquid end. A specialist
may need to take appropriate actions (using inert
gas, ...).
WARNING!
Only motors with a frequency converter: Danger of elec‐
tric shock
The danger of electric shock remains for 3 minutes after
the mains voltage has been switched off on conducting
parts of the motor with an integrated frequency converter
and on the lines themselves.
– After switching off, allow the device to stand for 3
minutes before opening the terminal box.
CAUTION!
Warning of personal injury and material damage
The metering pump may only be operated by trained
personnel. The operator is responsible for ensuring that
under the given operating conditions (pressure, tempera‐
ture, corrosiveness, etc.) danger to the operating per‐
sonnel is avoided by use of appropriate accident preven‐
tion measures.
CAUTION!
Only motors with a frequency converter: The motor can
be damaged
The input current limiter could be damaged if a motor
with an integrated frequency converter is restarted within
3 minutes of the mains voltage being switched off.
– After switching off, allow the device to stand for at
least 3 minutes before restarting.
CAUTION!
Feed chemical could escape
– Check suction and discharge lines, and liquid end
with valves, for leak-tightness and tighten if neces‐
sary.
– Check whether the necessary flushing pipes or
bleed lines have been connected.
CAUTION!
Liquid end may be damaged
– Always fit a filter in the suction line with feed chemi‐
cals with a particle size greater than 0.3 mm
