When ordering spare parts, make sure to state all the information
given on the pump and motor name plates.
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 inhibitors.
The respective manufacturer's instructions are to be observed.
• The fluid must be sediment-free.
• Salmson'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.
NOTE
The flow value shown on the IR-PDA Module 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 type of pump.
NOTE
Always read and follow the material safety data sheet for the fluid
being pumped!
