1)
This product is a professional device within the meaning of EN 61000-3-2.
2)
Mean value of the sound-pressure levels on a spatial cuboid measuring surface at a dis-
tance of 1 m from the pump surface in accordance with DIN EN ISO 3744.

For additional information on permissible fluids, see "Fluids".
4)
For motor powers of 11 ... 22 kW, electronic modules for IT networks are optionally
available. Compliance with the specified values in accordance with EN 61800-3 can only
be guaranteed for the standard version of TN/TT networks. Non-observance can result in
EMC faults.

...
No oxygen binding agents, no chemical sealants (ensure
closed system from corrosion perspective according to VDI
2035 (CH: SWKI BT 102-01); rework leaky points).
Note that water-glycol mixtures or fluids with a viscosity different than that of clean water
increase the power consumption of the pump. Only use mixtures with corrosion protection.
Observe the relevant manufacturer's specifications!
• The fluid must be sediment-free.
• Wilo's approval must be obtained for the use of other fluids.
• Mixtures with a glycol content > 10% influence the flow calculation.
• When using water-glycol mixtures, the use of an S1 variant with a corresponding mech-
anical seal is generally recommended.
• For state-of-the-art systems, compatibility of the standard (mechanical) seal with the
fluid can be assumed under normal system conditions.
Special circumstances may require special seals, for example:
