10. Technical data

Supply voltage
1 x 230-240 V –10%/+6%, 50 Hz, PE.
Motor protection
The pump requires no external motor protection.
Enclosure class
IP 42.
Insulation class
H.
Relative air humidity
Maximum 95%.
Ambient temperature
0°C to +40°C.
Temperature class
TF110 to CEN 335-2-51.
Liquid temperature
Maximum +110°C.
Continuously: +15°C to +95°C.
Pumps in domestic hot-water systems:
Continuously: +15°C to +60°C.
To avoid condensation in the terminal box and the
stator, the pumped liquid temperature must always
be higher than the ambient temperature. See the ta-
ble below:
