9. Storing the product

9.1 Storing the product
During long periods of storage, the pump must be
protected against moisture, heat and cold.
If the product is stored for more than one
year, turn the impeller by hand at least
once a month.
Leave the polyurethane-embedded plug mounted in
the pump to prevent moisture from penetrating into
the motor.
If the pump has been in use, the oil needs to be
changed before storage. See section Checking and
changing the oil.
After a long period of storage, the pump must be
inspected before it is put into operation. Make sure
that the impeller can rotate freely. Pay attention to the
condition of the shaft seal, O-rings, oil and the cable
entry.
