9. Fault finding the product
When the pump is first started, the shaft may
rotate slowly until water has fully penetrated the
bearings.
If the pump does not run, the shaft can be
rotated manually. To accomplish this:
1. Switch off the power supply.
2. Close the isolating valves on either side of
the pump.
3. Remove the large screw in the middle of the
nameplate.
4. Insert a small flat-blade screwdriver into the
end of the shaft, and gently turn it until the
shaft moves freely. See fig.
2 .
5. Replace and tighten the large screw.
Open the isolating valves and wait 2 to 3
minutes for the system pressure to equalize
before starting the pump.
