CAUTION!
Danger from incorrectly operated or inadequately main‐
tained pumps
Danger can arise from a poorly accessible pump due to
incorrect operation and poor maintenance.
– Ensure that the pump is accessible at all times.
– Adhere to the maintenance intervals.
WARNING!
An on/off switch may not be fitted on the pump,
dependent on the identity code and installation.
The pump can therefore start up immediately when it is
connected to the mains power supply.
All isolating protective equipment must be installed for operation:
Power end front cover
n
Motor fan cowling
n
Motor terminal box cover
n
Hood
n
In exactly the same way, plug all relays, modules and options into the
hood - if fitted.
Only remove isolating protective equipment when the operating instruc‐
tions request you to do so.
In the event of an electrical accident, disconnect the mains cable from the
mains/power supply or press the emergency cut-off switch fitted on the
side of the system.
If feed chemical escapes, ensure that the hydraulic environment around
the pump is at atmospheric pressure as well. Refer to the material safety
data sheet for the feed chemical.
