6.1 Precautions — Maintenance guidelines

Perform these tasks during maintenance and before reassembly

Ensure existing index markings are in line during reassembly

Insulation-test the reassembled drive unit

Test-run the reassembled pump before normal operation

Perform a ground (earth) continuity test after service

5.2 Estimate zinc anode replacement intervals

Remove, weigh, and reinstall one or more of the exterior zinc anodes before starting up the pump

After two months, remove and weigh the same zinc anode or anodes again

Enter the lapsed time in days between the initial and second weighing

Enter the anode weight loss in grams

Calculate the anode consumption rate (days/gram)

Calculate future replacement intervals based on the selected fraction of zinc remaining (0.25–0.50)

Check for water in the oil housing

Does the oil contain too much water?

If the oil contains too much water

Check for liquid in the stator housing

Check the mechanical seal unit, the O-rings, and the cable entry, if liquid was found
