6.5  Clean the external fan cover

If the fan cover is not kept clean, the air flow over the pump can be restricted and the

pump may overheat.

1.

Switch off the pump and disconnect it from the electrical supply.

2.

Use a dry cloth and a soft brush to remove dirt and deposits from the fan cover.

6.6  Replace the tip seals

This instruction is applicable to the replacement tip seal kit (contained in minor service

kit, refer t

Service kits on page 36

) that must be fitted.

6.7  Test the motor condition

CAUTION:

Do not flash test the pump or damage to the inverter may result.
