Disposal; Uped; Start/Stop; Max. Curve - Grundfos UPED 50-12 Montage- Und Betriebsanleitung

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
table below:
