DANGER
Risk of fatal injury from falling parts!
The pump itself and pump parts can be extremely heavy. Falling parts
pose a risk of cuts, crush injuries, bruises or impacts, which can be fatal.
• Always use suitable lifting equipment and secure parts against falling.
• Never stand underneath a suspended load.
• During storage and transport, as well as before all installation and as-
sembly work, ensure that the pump is in a safe position and standing
securely.
WARNING

Hot surface!

The entire pump can become very hot. There is a risk of burns!
• Allow the pump to cool down before commencing any work!
WARNING
Risk of scalding!
At high fluid temperatures and system pressures, allow the pump to cool
down first and then depressurise the system.
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
min
Approximate calculation of Q
Q = 10 % x Q
min max pump
The factory pre-installed component arrangement relative to the pump housing (see Fig. 13)
can be changed on site if required. This may be necessary, for example, in the following
cases:
• Ensuring pump venting
• Enabling better operation
• Avoid impermissible installation positions (motor and/or electronic module point down-
wards).
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.
