10. Technical data
10.1 Enclosure class
IPX4D
10.2 Sound pressure level
The sound pressure level of the pump is lower than
70 dB(A).
10.3 Ambient temperature
-30 to 55 °C.
Relative humidity
Maximum 95 %.
Liquid temperature
-20 to 60 °C.
Insulation of pump head
Do not insulate the pump head. If you insulate the
pump display and the liquid temperature is lower
than the ambient temperature, do not cover the drain
holes in the stator housing.
