he corresponding terminals.In outdoor installations, the power-supply cable must be at least of type “H07 RN-F”. Single-phase motors will be equipped with built-in thermal protection.In the case of three-phase motors, the user should provide thermal protection complying with the insta- llation rules in force. The diagrams in Fig.(1) will allow correct electrical con- nection. 5.BEFORE FIRST STARTING THE PUMP ENSURE That the grid voltage and frequency match those featured on the specification plate and that the pump shaft turns freely. That the motor turns in the same direction as indicated by the arrow on the fan cover.With three phase motors, if the direction is wrong, switch two of the phases on the protec- tion board. That the pump body and suction pipe are completely full of water and that there are no leaks at the joints or connec- tors.

Check the current drawn and duly adjust the thermal relay (three phase versions only). If the motor does not work or the pump not draw water, try to dis- cover the cause of the problem consulting the troubleshooting guide shown below. 7.MAINTENANCE Our pumps require no specific maintenance or program- ming.Notwithstanding, we recommend that in cold weather, when there is risk of freezing, the pump body be completely drained by removing the drain plug.If the pump is to remain unused for a long period of time, it should be drained, cleaned and stored in a dry, well-ven- tilated place. 22MANUEL D’INSTRUCTIONS F Avertissements pour la sécurité des personnes et des choses Le symbole associè à l’un des mots:“Danger”et “Avertissement”indique la possibilité de danger dérivant du no...
