disconnect the power supply and make sure
that the device could not accidentally operate.
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
(par. 12.3 fig. 4).

necessary to take out the delivery casing (20.00/14.00)
by removing the screws (20.12/14.24).
Before restarting the unit, check that the shaft is not
jammed and fill the pump casing completely with liquid.

the pump casing before dismantling the pump.
