minutes and try again.

5. The impeller may be jammed. Disconnect from the mains

supply, remove the bottom strainer and remove any

objects that may be obstructing the impeller. Replace

the strainer and try again.

6. If the pump still fails to start consult your CLARKE dealer for

advice.

7. Floatswitch may be jammed against side wall or

prevented from moving.

8. Water level too low - float switch in OFF position - lift float

to check switch.

Check to ensure strainer is not blocked.

2. Discharge tube clogged or obstructed.

3. The head may be too great, i.e. you are trying to lift the

water too great a distance for the pump to cope with.

(See specifications on page 2).

4. Air bubble in the pump, produced during the plunge.

Plunge the pump again at an angle and shake it whilst

lowering to remove any air trapped in the system.

down position.

Float switch may be faulty. Consult your CLARKE dealer

for advice.

Thermal overload has operated. If this condition persists,

investigate the cause. Are you attempting to pump liquid

which is too heavy for the pump (mud, slurry etc.)

2. Pump has run dry or float switch has cut in.

3. A foreign object has jammed the impeller.
