fitted in inlet and outlet.

(see page 1 of instructions)

Ensure all push-fit pipe connections are fully sealed and O-rings are not

damaged or displaced.

The water pumping capacity can be adjusted by adjusting pump speed.

Adjust pump speed using the calibration setting.

Please refer to instructions overleaf

When increasing the pump speed*, if the pump still performs low or no

suction, take off the pump head by removing the clamp ring. Examine the

inlet and outlet flap valves for traces of hard debris such as grit.

If so, wash out all debris and ensure the

valves are seated correctly.

If problem persists, check all connections for air leaks or blockage in

either the inlet or outlet pipework. Repair any leaks or clean blockages.

PUMP WILL NOT STOP

The pump has an overrun timer to allow it to continue to run after the

shower has been switched off. This timer is factory set to 20 seconds.

With the power supply switched on, disconnect the flow sensor. Separate

the disconnected wires. This will simulate the flow sensor turning off.

Pump should stop after the overrun time. If not, check the controller

display panel or cabling. If the pump has not stopped, disconnect power

supply and contact customer services.

If controller is OK, remove and check the flow sensor, flush it through with

water or replace it as necessary.
