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:
System pressure
The system pressure is indicated on the pump
flanges:
Inlet pressure
The following minimum pressures must be available
at the pump inlet during operation:
EMC (electromagnetic compatibility)
EN 61800-3.
Sound pressure level
The sound pressure level of the pump is lower than
54 dB(A).
Leakage current
The pump mains filter will cause a discharge current
to earth during operation. I
leakage
< 3.5 mA.
Inputs and outputs
11. Disposal
This product or parts of it must be disposed of in an
environmentally sound way:
1. Use the public or private waste collection service.
2. If this is not possible, contact the nearest
Grundfos company or service workshop.
