TROUBLE SHOOTING

A. PUMP WILL NOT START

1. Check to ensure Power is switched on.

2. Check fuse (consult an electrician if in doubt).

3. If extension lead is fitted, check connections (consult an electrician if in

doubt).

4. Internal thermal cutout has not reset. Leave for 15 minutes and try again.

5. The Impeller may be jammed. Disconnect from the mains supply, remove

the bottom strainer and outlet connection. Remove any objects that may

be obstructing the impeller. Replace the strainer and try again.

6. Float switch may be jammed against side wall or prevented from moving.

7. Water level too low - float switch in OFF position - Lift float to check switch.

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

B. PUMP WILL START BUT NOT PUMP

1. Check to ensure strainer is not blocked - clean as necessary

2. Discharge tube clogged or obstructed - clear as necessary.

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 pages 9 ).

4. Impeller may be damaged - Consult your CLARKE dealer

C. PUMP WILL NOT STOP

1. Float switch may be prevented from moving to the fully down position.

2. Float switch may be faulty. Consult your CLARKE dealer for advice.

D. PUMP STOPS RUNNING

1. Thermal overload has operated. If this condition persists, investigate the

cause. Are you attempting to pump liquid which is too dense for the pump

(mud, slurry etc.), or too high a temperature.

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

3. A foreign object has jammed the impeller.
