Ÿ

All installations must be provided with an isolator to cut off mains power supply 
and coarse current protection in the form of a fuse or MCB rated at 2-3 times 
the full load current as given on the pump plate.

Ÿ

Ensure that the power supply rating complies with the specification in these 
instructions.

Ÿ

Effective earthing must be provided according to local regulations.

Ÿ

Motors are protected against overloads by a thermal overload fitted in the 
motor windings.

5.  MAINTENANCE

The pump requires no routine maintenance and if correctly installed, should give 
long term trouble free service. However, the following should be noted:-

Ÿ

If pump performance drops check for debris in the impeller. If observed, flush 
with water to clean. If this action is insufficient, remove the suction cover and 
clean around the impeller.

Ÿ

Particularly check the pump seating location and clear any debris and silt that 
may have accumulated.

NOTE

Before  carrying  out  any  maintenance  ensure  the 
electrical supply is isolated.

NOTE

Before using the pump again, first “soak” it so that any 
possible dirt residues do not block the appliance.
