Before every maintenance operations disconnect the power supply and make sure that the device could not

In the case of water containing chloride (chlorine, sea water), the risk of corrosion increases in stagnant water
conditions (also with an increase in temperature and decrease of pH value). In these cases, if the pump
remains inactive for long periods, it must be emptied completely and, preferably, dried.
For good measure, as in the case of temporary operation with dirty liquids, run the pump briefly with clean
water to remove deposits. When the pump remains inactive it must be emptied completely if there is a risk of
freezing.
Before restarting the unit, check that the shaft is not jammed and fill the pump casing completely with liquid.

the pump casing and the pipes.
