MAINTENANCE
After starting up the plant, it is advisable to inspect and clean it, especially the no return valve, about every three months. This
interval may be increased after the first inspections have given a favourable outcome.
Clean the pump accurately, removing any foreign bodies stuck in the intake grille and check that the float moves freely. If necessary,
remove the pump from the tank.
It is recommended to clean the system at least once a year with running water, operating the pump repeatedly.
