3.1
Intended use
The circulators in this series are designed for warm water
heating systems and similar systems with constantly
changing flows.
The approved fluids are heating water in accordance with
VDI 2035, and water/glycol mixture at a mixing ratio of 1:1.
If glycol is added, the delivery data of the pump must be
corrected according to the higher viscosity depending on
the mixing ratio.
Intended use includes the observation of these instructions
as well as of specifications and labelling on the pump.
Any other use is regarded as improper use.
