1)
TN and TT power supplies with earthed live wires are not permitted.
2)
For more detailed, product-specific information such as power consumption, dimensions
and weights, refer to the technical documentation in the catalogue or Wilo-Select online.
3)
Over Voltage Category III + Surge Protective Device/Metall Oxid Varistor
4)
Average value of the sound-pressure levels on a spatially rectangular measuring surface
at a distance of 1 m from the pump surface in accordance with DIN EN ISO 3744.
5)
For more information about permissible fluids, see the "Fluids" section.
6)
In the case of the DN 100 and DN 125, pump types with motor powers of 2.2 and 3 kW,
EMC irregularities can occur under unfavourable circumstances when used in residential en-
vironments with low electrical power in the conducted range. In this case, please contact
WILO SE so that together we can find a quick and suitable shutdown measure.

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).
Fluids
Water-glycol mixtures or fluids with a different viscosity than pure 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 proportion of glycol of > 10 % influence the Δp-v characteristic curve
and the flow calculation.
• The compatibility of the standard seal/standard mechanical seal with the fluid is gener-
ally given under normal system conditions.
Special circumstances may require special seals, for example:
–
solids, oils or EPDM-attacking substances in the fluid,
–
air content in the system, etc.
Observe the safety data sheet for the fluid to be pumped!
NOTICE
When using water-glycol mixtures, the use of an S1 variant with a corre-
sponding mechanical seal is generally recommended.
Accessories have to be ordered separately.
• 3 mounting brackets with fixation material for installation on a base
