Average value of the sound-pressure level at a spatially rectangular measuring surface at a distance of 1 m from the pump surface in accordance with
DIN EN ISO 3744.

For more information about permissible fluids, see the "Fluids" section on the next page.
3)
Electronic modules for IT networks are optionally available for motor powers from 11 to 22 kW. Compliance with the values specified in EN 61800-3 can
only be guaranteed for the standard version of TN/TT networks. Failure to observe this instruction may result in EMC interference.

Permissible fluids
Heating water
(in accordance with VDI 2035/VdTÜV Tch 1466/CH: in accordance
with SWKI BT 102-01)
...
No oxygen binding agents, no chemical sealants
(ensure system is closed in terms of corrosion according to
VDI 2035 (CH: SWKI BT 102-01); rework leaky points).
...
If water-glycol mixtures are used (or fluids with a viscosity other than
that of pure water), an increase in power consumption of the pump is
to be taken into account. Only use mixtures with corrosion protection
inhibitors. The respective manufacturer's instructions are to be
observed!
• The fluid must be sediment-free.
• Wilo's approval must be obtained for the use of other fluids.
• Mixtures with a proportion of glycol of > 10 % influence the Δp-v
pump curve and the flow calculation.
• In systems built according to the state of the art, it can be assumed
under normal system conditions that the standard seal/standard
mechanical seal is compatible with the fluid. Special circumstances
(e.g. solid material, oils or EPDM-corrosive substances in the fluid, air
in the system etc.) may require special seals.
NOTICE:
The flow value shown on the IR-Monitor/IR-Stick display or output to
the building management system must not be used to control the
pump. This value is merely an indicator of general trends.
A flow value is not output on every pump type.
NOTICE:
Always read and follow the material safety data sheet for the fluid
being pumped!
