How to use
Install the pump in a horizontal or vertical position according to system layout and manufacturer instructions, ensuring correct flow direction and secure flange or threaded connections compatible with DN 25 piping. Connect to a single-phase 230 V, 50 Hz supply using proper grounding and a suitably rated circuit breaker.
