ELECTRICAL INSTALLATION

Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply through an approved 13 amp BS 1363 plug or a suitably fused isolator switch.If the plug has to be changed because it is not suitable for your socket, or because of damage, it must be removed and a replacement fitted, following the wiring instructions shown below. The old plug must be discarded safely, as insertion into a power socket could cause an electrical hazard.The colours of the wires in the power cable must agree with the markings on the plug.

•  Connect the BLUE wire to the terminal marked N.
•  Connect the BROWN wire to the terminal marked L.
• Connect the YELLOW AND GREEN wire to the terminal marked E or

AN APPROVED RESIDUAL CURRENT DEVICE (RCD) WHICH HAS A TRIPPING CURRENT OF LESS THAN 30 mA MUST BE USED. If you are not sure consult a qualified electrician.

INSTALLATION OF THE PUMP

IMPORTANT:
The pump MUST NOT be connected to the mains power supply until all hose/pipe installations are completed.If any part of the system is to be connected to the mains water supply, do ensure that you comply with your local water authority regulations. Because of the variety of possible installations, no plumbing accessories are supplied as standard with your pump. However, accessories designed specifically for this range of pumps are available from your CLARKE dealer.The pump must always be installed and operated in a horizontal position i.e. with the outlet port facing vertically upwards. The fixing holes in the base should be used as necessary to secure the pump firmly in its operating position. Also, ensure that there is adequate air circulation around the motor.Avoid situations where there is the risk of water coming into contact with the outside of the pump. Neither the motor or the terminal box are designed to be waterproof. These notes are for guidance on how to achieve a proper working system.The schematic diagram opposite illustrates a typical pipework installation.The suction lift i.e. the vertical distance between the water level and the pump should not exceed the distance specified for your pump.

A foot valve and filter should be fitted to the lowerend of the suction hose, as illustrated below, so as to help retain water in the suction system and to prevent the possibility of large foreign bodies entering the pump body.
A 1” BSP hose adapter will be required for connection to the inlet port. This is available from your dealer.The performance of your pump will be effected by the diameter of the inlet pipe – any restriction will greatly reduce the flow. We strongly recommend that you use a diameter pipe which is as large as practicable, with a suitable reducer for connection to the 1” BSP inlet adapter.

The delivery hose should be attached to the outlet adapter which is supplied.A gate valve may be installed in-line on the delivery side of the pump which can be set as required to regulate the flow of water. Do not place any such restriction on the suction side of the pump unless it is an isolator valve in a gravity fed system.It is IMPORTANT to note also that this pump should not be operated with the delivery valve completely closed.To prevent unnecessary strain or possible distortion to the pump, ensure that adequate support is provided to the hoses and/or pipes. Remember they will be considerably heavier when filled with water.Should sand, chemical or other contaminants come into contact with the pump, flush through with cold clean water as soon as possible.

Protect the pump and pipework from freezing. The formation of ice may cause serious damage.Where the pump is to be a permanent fixture, the fittings to the pump MUST be flexible, i.e. a short piece of hose should be inserted between rigid metal pipework and the pump.It is strongly recommended that in addition to the coarser foot filter, an inlet filter should be fitted to prevent the possibility of any foreign body from entering the pump. This is particularly important in the case of multi- stage pump such as the CBM240E. A filter specifically designed for all pumps in the range is available from your CLARKE dealer.The filter bowl is transparent allowing a visual check as to the condition of the filter cartridge. The filter cartridge is a washable net type with a rated filtration of 60 microns, suitable for the efficient removal of suspended particles such as sand. The filter is NOT designed to filter mud, sludge etc.This pump is provided with a non-return valve connected to the inlet port. Screw the non return valve into the inlet port, ensuring the arrow, stamped on the valve points inwards towards the inlet port. Tighten the valve, BUT DO NOT OVERTIGHTEN, then screw the filter on to the valve – again DO NOT OVERTIGHTEN. The filter should hang vertically when completed.This pump is set up as a BOOSTER Pump by incorporating the CLARKE EPC 1000 HYDROTRONIC UNIT – a computerised electronic device which automatically switches the pump ON and OFF whenever a tap, or other restriction in the outlet side of the pump, such as a spray lance etc., is turned ON or OFF.Please ensure you are thoroughly familiar with the operation of this device by reading the enclosed leaflet describing its’ operation and maintenance, before you operate the pump. It is important to note that in order for the hydrotronic unit to operate correctly, the maximum head ABOVE THE outlet OF THE HYDROTRONIC UNIT, is 14 metres. i.e. Although the pump is capable of delivering water to a maximum head of 48 metres, the hydrotronic unit will not switch the pump ON if the vertical height above outlet of the unit is greater than 14 metres.

PRIMING

When suction lift is used to draw water into the pump it is essential that all connections and hoses are completely air tight, otherwise the system will not work.Although the pump is a ‘self priming’ type, it is nevertheless necessary to completely fill the inlet side of the pump with water before being started for the first time, or if the system has been drained for maintenance or repair purposes. This is known as priming the pump and is carried out as follows:-

1. .Locate and remove the small filler plug, situated on the top of the pump chamber, and slowly fill the pump with water until all air is expelled.

2. Adjust any device which may be fitted to the outlet side of the pump, so as to ensure as great a flow as possible.
   Switch on the pump and check for leaks. Water should start to flow through the system after a short while. If, after 2-3 minutes, depending upon the suction depth, water does not flow, check to ensure:

3. The inlet pipe is completely secure and completely free from defects. Even a pin hole could prevent the pump from drawingwater. This is the most common problem encountered when operating water pumps.

4.  The pump body has been primed correctly and is completely filled with water.

NOTE:
If the pump is gravity or pressure fed, priming will not be necessary, as the pressure of water will purge the system of air.It is essential that all connections and hoses are completely air tight, otherwise the system will not work.

TROUBLESHOOTING

over- heated, wait for it to cool down before trying again.
Faulty power connection| Insert plug securely.
No mains supply.| Check fused power supply and replace fuse if necessary (check fuse rating). Check circuit breaker.
Impeller seized/blocked| Disconnect pump from power supply.

Investigate cause and clear blockage

Pump fails to prime| Air leaks through suction hose joints (damaged hose or damaged clamp.)| Repair connections/ replace hose as necessary.
Blocked inlet hose| Check pipeline for block- age. Check any inlet valve fitted is fully open.
Pump runs but gives poor output| Congested material inside pump| Clean out & backflush pump.
Suction or delivery line obstructed.| Remove obstruction and ensure there are no kinks in delivery line.
Inlet pipe leakage.| Check inlet pipe and connector for leaks. Tighten as required.
Air leaks through damaged seal.| Renew seal.
Impeller damaged and making poor seal.| Return to your CLARKE dealer for repair.
Impeller / mechanical seal is badly worn.| Return to your CLARKE dealer for repair.
 | High friction losses in the suction line.| Avoid unnecessary curves, restrictions or valves
---|---|---
Pump badly sited result- ing in suction lift too high| Set pump as close as possible to the level of the water to be pumped
Sudden loss of flow.| Blockage of inlet pipe| Check pipeline for blockage.
Undue vibration or noise.| Excessive flow of water.| Decrease flow of water. by adjusting inlet/outlet valves in system.
Resistance in inlet pipe caused by obstruction.| Check pipe and clean out as necessary
Loose rotating component| Return to your dealer for repairs.
Installation of pump is unstable.| Stop pump and re-position.
Air pocket in pump or pipeline.| Release plug in impeller housing to release air.
Damaged impeller| Return to your CLARKE dealer for repair.
Pump runs non-stop| Leaks on output side or cuts in and out rapidly| Ensure electrical con- nections are water tight. Check to ensure no taps are leaking. (smallest leak will cause hydro- tronic unit to operate.
Non-return valve faulty| Check and rectify

MAINTENANCE & CLEANING

The only maintenance required is a regular inspection to ensure that debris is not blocking the passage of water through the pump.If you suspect the pump is blocked by silt, leaf debris etc, disconnect it from the power supply and back-flush to clear any blockage using a garden hose.

• You will need to disconnect the outlet hose to do this. Always keep the pump in a clean condition, checking regularly for loose bolts or a damaged power cable etc. The pump should not be taken apart by the user if overhaul is required, but should be taken to your nearest CLARKE dealer for repair.
