Storing The Product - Grundfos SMD Installation And Operating Instructions Manual

9. Storing the product

Store mixers or flowmakers in a dry location in which
the temperature is not exposed to major fluctuations.
Do not expose the flowmaker propeller blades to
direct sunlight for more than a month.
If the mixer or flowmaker is stored for more than one
year, change the gearbox oil. Change the oil even if
the unit has never been in use. This is necessary due
to natural aging of mineral oil lubricants.
After a long period of storage, inspect the mixer or
flowmaker before putting it into operation. Make sure
that the blades can rotate freely. Pay attention to the
condition of the shaft seals, cable entry and sensors.
