the factory setting (delivery status).
4. Intended use
High-efficiency circulators in the Wilo-Para series
are exclusively intended for circulating fluids in hot-
water heating systems and similar systems with con-
stantly changing volume flows.
Permitted fluids:
• Heating water according.
• Water-glycol mixtures
* with a maximum of 50% glycol.
*Glycol has a higher viscosity than water. If admixtu-
res of glycol are used, the pumping data of the
pump must be corrected to match the mixing ratio.

Noticies
NOTICE
Only introduce ready-to-use mixtures to the
system. The pump must not be used to mix
fluid in the system.
Intended use includes observing these instructions
and the specifications and markings on the pump.
