WARNING!
Risk of burns with hot feed chemicals
If hot feed chemicals can heat the liquid ends above
the permissible surface temperatures, persons can
suffer burns from them.
– Consider attaching a "Hot surface" label to the
liquid end or ...
– fitting a guard plate.
WARNING!
Danger with high pressure
Feed chemicals at pressures above 100 bar can seri‐
ously injure people standing nearby in the event of a
discharge-side leak - particularly if energy stores, such
as pulsation dampers, are used.
– Wear protective goggles and protective clothing if
no protective panels are fitted.
WARNING!
Only with frequency control unit: Danger of electric
shock
There is still the risk of an electric shock on conducting
parts of the frequency control unit (e.g. frequency con‐
verter), the motor and the cables even after the mains
voltage has been switched off.
– Once switched off, allow the device to stand for as
long as is required in the operating instructions for
the frequency control unit and only then open the
terminal box.
WARNING!
Observe other operating instructions
Observe the safety information in the other operating
instructions.
CAUTION!
Do not permit the maximum permissible priming pres‐
sure on the suction side to be more than 10% of the
maximum allowable operating pressure. Otherwise the
pump will wear out quickly.
CAUTION!
Use the clamp lever to fix the manual adjustment
wheel following every adjustment of the stroke length.
