in line with the valid regulations (e.g. IEC, VDE, etc.)!
• The current type and voltage must correspond with the information on the type plate.
• Observe the specifications of local energy supplier!
• Observe accident prevention regulations!
• Never pull on the power cable
• Do not bend the cable
• Do not place any objects on the cable
• When using the pump in systems at temperatures over 90 °C,
use a connection line that is suitably heat resistant.

The system must be thoroughly flushed before
the pump is started up to prevent contaminants
or foreign bodies from remaining in the system.
Fill and vent the system correctly. To vent the
pump, loosen the indicated screw by turning it
anti-clockwise. Caution! Hot water may escape
here, depending on the system's operating state.
Afterwards, re-tighten the screw you can start
the pump in the desired mode.
Incomplete venting can lead to noises in the
pump and system.
Warning! Risk of burns!
The entire pump can be very hot,
depending on the operating state of the system.
