6 Faults
Faults may result from inadmissible modes of
operation. Such inadmissible modes of
operation – even brief ones – may cause
serious damage to the unit.
In connection with explosion protection, potential
sources of ignition (overheating, electrostatic and
induced charges, mechanical and electric sparks) can
result from these inadmissible modes of operation;
their occurrence can only be prevented by adhering to
the intended use.
Should there be any uncertainty about the remedy to
be applied, please inquire at the in-house pump office
or at the pump manufacturer's.
