The application guidelines according to DIN 24296 recommend keeping a supply for two years of continuous use
(→ 9.3 Spare parts for two years of continuous operation
according to DIN 24296, Page 35).
Have the following information ready to hand when ordering spare parts (→ type plate):
– Short designation of the pump
– Serial number
– Year of construction
– Part number
– Designation
– Quantity
7.4.4 Fitting the pump in the installation
(→ 5 Setup and connection, Page 12).

DANGER
Risk of fatal injury and material damage due to magnetic
field!
Make sure no-one w ith a heart pacemaker performs any
work on the pump.
Secure the workplace and cordon it off if necessary:
– Ensure staff with heart pacemakers keep a minimum
distance of 1 m.
– Make sure no magnetisable metal parts are able to be
attracted by the magnetic coupling of the pump.
– Makesurenopartsofthemagneticcouplingareable
to be attracted by magnetisable metal parts.
Keep magnetically sensitive objects at least 150 mm away
from the magnetic coupling.
For faults which are not specified in the following table or cannot be traced back to the specified causes, please consult the
