## Long description

How to use
Fit the circulator into the heating circuit following the system manufacturer’s instructions and local installation standards, ensuring correct flow direction and secure flange connections. Select the appropriate performance stage (1–4) to match system head loss and desired flow rate; start with the lowest setting and increase if heating delivery is insufficient.

Usage recommendations
Use with compatible heating fluids (treated water) in closed systems and avoid running the pump dry. Periodic inspection for leaks, correct alignment and system air content helps maintain efficiency. When replacing an older circulator, verify flange and shaft dimensions to ensure direct compatibility and minimise installation effort.
