• Ensure the electrical cable complies with H07RN-F
specifications or higher.
• Connect the electrical cables to the motor following the
wiring diagram shown in Fig. 3.
• The pump should be connected to a residual current
circuit breaker with a sensitivity of no more than 30
mA.
• Always ensure the device is properly grounded.
• Electric motors typically operate at a voltage of 220-
240V ~ 50Hz single phase.
• Check that the power cable is free from damage.
• Protect the electrical connection from water splashes.
• When used outdoors, ensure that electrical connections
are splash-proof and not submerged in water.
4.3- Start-up
WARNING! Do not start the electric pump without first filling it with water. Running it
dry can cause irreversible damage to the mechanical seal.
Priming
• IMPORTANT! Filling the pump with water is only necessary if the
pump has been drained or if no water is present (e.g., in a newly
installed pump).
• Unscrew the priming plug (b) and completely fill the pump body
with water. Once filled, replace and tighten the plug securely.
Starting
• Ensure all valves in the pipework are open.
• Make sure the end of the suction line is at least 20 cm below the
water surface.
• Connect and check power supply.
• Start the pump and check for any leaks around the pump body,
suction line, and fittings. When the water flows smoothly, turn off the pump. It is now ready
for use.
• If the water level drops in the pump body or the discharge is uneven, air intake may be the
issue. Turn off the pump, inspect the suction pipe fittings, and repeat the priming process by
refilling the pump body with water.
