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.
• 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.
NOTE:
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 type of pump.
NOTE:
Always read and follow the material safety data sheet for the fluid
being pumped!
• Pump IL-E/DL-E/BL-E
• Installation and operating instructions
Accessories must be ordered separately:
• IL-E/DL-E:
3 mounting brackets with fixation material for installation on a base
• BL-E:
4 mounting brackets with fixation material for installation on a base
for rated power of 5.5 kW and above
• Blind flanges for double pump housing
• IR Monitor
• IR-Stick
• IF-Module PLR for connecting to PLR/interface converter
• IF-Module LON for connection to the LONWORKS network
• IF-Module BACnet
• IF-Module Modbus
• CAN IF-Module
For a detailed list, consult the catalogue and spare parts documentation.
NOTE:
IF-Module may only be plugged in when the pump is de-energised
(voltage-free).
