WINTERING
fig. F
fig. G
Risk of freezing: if the pump remains at a temperature of less than or equal to 0 ° C for a long
time, the pump body must be completely emptied through the special drain located below the
pump body in order to prevent breakage and damage to the hydraulic components (fig. G). Then
clean with clean water, dry, remove and store in a dry place. The aforementioned operations are
also recommended for long periods of inactivity in normal temperature conditions. After a long
period of inactivity, repeat all the operations described for the first start-up.
