WARNING!
Pumping flammable media
Possible consequence: Fatal or very serious inju‐
ries.
Pumping flammable media is not permitted.
Observe the material safety data sheet for the
medium.
WARNING!
Live parts
Possible consequence: Fatal or very serious inju‐
ries.
Measures:
–
Disconnect the system from the power supply
before opening the housing of a component.
–
If the housing of the pump, controller, terminal
box or other components is broken, ruptured or
obviously damaged, immediately switch off the
system and arrange for its repair.
–
Only carry out set-up / maintenance / repair
and service work when the system is shut
down and the electrical power disconnected.
Calibration and maintenance work on the sen‐
sors represents an exception to this. This work
can be carried out while the system is live.
Please also observe the information in the
operating instructions for the sensors and con‐
trollers.
–
Check that the seals are sitting correctly after
closing the housing of the pump, controller or
terminal box
We fundamentally recommend the use of appro‐
priate residual current circuit breakers (RCCB) or
other residual current devices (RCD) providing
they can be installed sensibly and professionally
within the electrical installation. Please adhere to
all national standards and regulations.
WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious inju‐
ries.
Please ensure when handling hazardous sub‐
stances that you have read the latest safety data
sheets provided by the manufacture of the haz‐
ardous substance. The actions required are
described in the safety data sheet. Check the
safety data sheet regularly and replace, if neces‐
sary, as the hazard potential of a substance can be
re-evaluated at any time based on new findings.
The system operator is responsible for ensuring
that these safety data sheets are available and that
they are kept up to date, as well as for producing
an associated hazard assessment for the worksta‐
tions affected.
