PRIMING THE PUMP

Remove the filler plug on top of

the pump case and prime the

pump by filling completely with

water, leaving no air gap.

Remember the pump is self-

priming only when filled, after

which, it will re-prime itself without

refilling. Refilling is necessary only if

the pump has been drained, or if

all the water has been lost.

1. Open any valves in the pipeline.

2. Connect the power supply and switch the pump ON.

3. Wait for the pump to prime.

4. If the motor fails to start or the pump does not deliver water refer to

TROUBLESHOOTING.

NOTE: Filling the suction pipe with water will speed up the priming

process, and it is recommended that a non-return valve be fitted

to the end of the suction pipe.

In the event of blockages, where debris has entered the suction chamber, the

chamber can be taken off and cleaned out as described under

Maintenance.

5. Periodically, check the level of the water being removed and never allow

the pump to run dry.

6. Stop the pump by switching the pump the OFF (O) position.

• Strain caused by vibration can be reduced by connecting a short

flexible hose between any rigid pipework and the pump.

• Any restriction in the pipeline will greatly reduce the flow.

• Ensure that the hoses and pipes are supported along their entire

length. They will be considerably heavier when filled with water.

• We recommend that you install isolation valves either side of the

pump in order to isolate the pump during maintenance/removal.
