CAUTION
Alfa Laval cannot be held responsible for incorrect installation.
Never stick your fingers or any tool through the adaptor or the
drain hole in the pump casing when the pump is running.
WARNING:
Alfa Laval recommends the installation of a lockable
repair breaker. If the repair breaker is to be used as
an emergency stop, the colours of the repair breaker
must be red and yellow.
CAUTION
The pump does not prevent back flow when
intentionally or unintentionally stopped. If back flow
can cause any hazardous situations, precautions
must be taken e.g. check valve to be installed in the
system preventing the problems described above.
NOTE!
In case of shaft seal leakage, the media will drip from
the slot in the bottom of the adaptor. In case of shaft
seal leakage, Alfa Laval recommends placing a drip
tray underneath the slot to collect the leakage.
