CAUTION! Risk of property damage!
Risk of property damage if the electronic module is not installed.
• Normal operation of the pump is only permitted with the electronic
module installed.
• The pump is not allowed to be connected or operated without the
electronic module being installed.
DANGER! Risk of fatal injury!
The pump itself and pump parts can be extremely heavy. Falling
parts pose a risk of cuts, crush injuries, bruises or impacts, which
may lead to death.
• Always use suitable lifting equipment and secure parts against falling.
• Never stand underneath a suspended load.
• Make sure the pump is securely positioned and is stable during
storage and transport as well as prior to all installation and other
assembly work.
CAUTION! Risk of property damage!
Risk of damage due to incorrect handling.
• Have the pump installed by qualified personnel only.
• The pump may never be operated without the electronic module
being installed.
CAUTION! Damage to the pump due to overheating!
The pump must not be allowed to operate dry for more than
1 minute. Dry running causes a build-up of energy in the pump,
which can damage the shaft, impeller, and mechanical seal.
• Make sure that the volume flow does not fall below the minimum
value Q .

The component arrangement concerning the pump housing is pre-
installed as a factory setting (see Fig. 17) at can be changed if need be
at the operating location. This can be necessary, for example, to:
• Ensure the venting of the pumps
• Make operation easier
• Prevent impermissible installation positions (i.e. motor and/or elec-
tronic module downwards)
In most cases, it is enough to rotate the motor impeller unit relative to
the pump housing. The possible arrangement of components is the
result of the permitted installation positions.
