Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com INSTALLATION Because of the number of possible installations, no accessories are supplied with your pump except for a pair of male inlet/outlet adaptors. However accessories are available from your nearest Clarke dealer. See the suggested list on page 13. NOTE: It is recommended that the end user should consult a qualified installer if there are any doubts as to the suitability of this product for a particular installation. IMPORTANT: The pump MUST NOT be connected to the mains power supply until all hose/pipe installation is completed. INSTALLATION OF THE PUMP 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 to secure the pump firmly in it’s operating position. Mount the pump on raised blocks or a purpose built platform to protect it from flooding. Some kind of anti-vibration mounting is also desirable. Always ensure there is adequate air circulation around the motor. The pump should be installed in a dry, well ventilated enclosure, sheltered from rain. ELECTRICAL INSTALLATION The pump should be located at such a distance away from any pond or pool, as to avoid the possibility of immersion and the power supply should also be a safe distance away. If in doubt, please contact your electrical specialist and refer to national regulations. Avoid situations where the pump could become drenched with water as neither the motor or terminal box are designed to be totally waterproof. Ensure the pump & its power cable do not create a safety hazard for people walking past it. Before switching the product on, make sure that the voltage of your electricity supply is the same as that indicated on the rating plate. This product is designed to operate on 230VAC 50Hz. Connecting it to any other power source may cause damage.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com PIPE/HOSE CONNECTIONS The pump inlet and discharge ports are both 2” BSP (51 mm) female threads and accept the adaptors supplied. Hoses with the same diameter should be used and secured to the adaptor with a suitable hose clip. Ensure all connections are air tight when under pressure but not so tight as to crack the plastic inlet/outlet adaptors. ADDITIONAL CONSIDERATIONS

  • Strain caused by vibration can be reduced by connecting a short flexible hose between any rigid pipework and the pump.
  • We recommend that you always use pipes/hoses with a minimum diameter of 2” (51 mm).
  • 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.
  • A gate valve may be installed in-line on the delivery side of the pump which can be adjusted as required to regulate the flow of water and can assist in priming the pump.
  • If there is any chance of freezing, protect the pump and pipework with suitable lagging. The formation of ice may cause serious damage.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com USEFUL ACCESSORIES SUCTION LIFT OR GRAVITY FEED There are two possible methods of pipework installation. 1. Suction Lift. Used to draw clean water from a pool or well providing the vertical distance between the foot valve and the pump does not exceed the 8 metres specified for this pump. It is essential that all connections and hoses are airtight or the system will not work effectively. A foot valve/filter fitted to the lower end of the suction hose, (as illustrated), is essential to retain water in the system as the pump is not self priming. 2. Gravity Feed. Used to draw water. from a tank above ground. 2” BSP Plastic Foot Valve Filter FVF20 Part No:7950684 2” dia Reinforced Suction/Delivery Hose Part No:7955020 2” dia Layflat Delivery Hose 10M Part No:7955160 2” BSP Female Coupling Part No:7950320 2” BSP Male Coupling Part No:7950220 2” Hose Adaptor 90o Bend Part No:7950205

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com PRIMING THE PUMP Before using the pump for the first time the inlet (suction) side must be filled with water to prime the pump as follows:- 1. With all inlet pipes/hoses, but no outlet hose connected, pour water into the outlet port until all the air is expelled. 2. Connect the outlet hose to the outlet port. If the outlet hose is already connected, a priming port and threaded plug are provided, adjacent to the outlet as shown. NOTE: As the priming hole is quite small, it is necessary to fill the inlet (suction) pipe with water before connecting to the pump, and top up through the priming port once the pipe is connected. A non-return valve will need to be fitted to the inlet pipe for this purpose. 3. Switch on the pump.

  • Water should start to flow through the system. 4. Check for leaks and correct if necessary. 5. Adjust any device such as a non-return valve, which may be fitted to the outlet side of the pump, to maximise efficiency.
  • Do not place any restriction on the inlet or discharge hoses. Remember - this pump is designed for pumping CLEAN WATER ONLY. DO NOT USE for pumping chemicals or other flammable or corrosive liquids. OPERATION 1. Open any valves in the pipeline. 2. If operating the pump for the first time, prime the pump as described. on page 8. NOTE: Refilling (re-priming) is only necessary if the pump has been drained. 3. Connect to the power supply and switch on.
  • When water starts to flow through the system check for leaks and correct if necessary.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

  • If the motor fails to start or the pump does not deliver water, refer to TROUBLESHOOTING.
  • Never operate the pump when not primed with water or if the inlet is blocked which would allow the pump to run dry, causing damage. NOTE: Filling the suction pipe with water will speed up the priming process, and it is important that a non-return valve be fitted to the end of the suction pipe. 4. Stop the pump by switching off the power supply. PERFORMANCE CURVE CARE DURING USE 1. DO NOT allow the pump to run dry, otherwise the seal between the pump and motor may be damaged. If a leak occurs at this point, allowing water to pass from the pump to the motor, take the pump to your Clarke dealer for overhaul. 2. In the event of a blockage, where debris has entered the pump, it can be cleaned out as described under MAINTENANCE. 3. DO NOT USE for pumping chemicals or other corrosive liquids. Should contaminants enter the pump, flush through with water as soon as possible to prevent damage. 4. If the pump is being used to drain a pool, ensure there is adequate drainage and there is no risk of damage to property as a result of water being discharged. If a flexible hose must be laid across a roadway, protect it with wooden planking.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com MAINTENANCE Inspect the pump/hoses regularly to ensure that debris is not blocking the passage of water. If you suspect the pump is blocked by silt, leaf debris etc, disconnect it from the power supply, disconnect the discharge hose and back-flush to clear any blockage using a hosepipe. Always keep the pump in a clean condition and check regularly for damage to the power cable etc. AFTER USE After use, and if the pump will not be used over the winter period, or if there is danger of freezing, always drain the pump body. If the pump has been used with contaminated or salty water, it should be thoroughly flushed with clean water following use, both inside and out. It should then be drained and covered over, if not already sheltered from the weather. If the pump is seized following a period of inactivity, it may be possible to free it off. Ensure the pump power supply is turned off before by inserting a screwdriver into either the infeed or discharge port and dislodging a jammed impeller. If this is not successful it may be necessary to remove the relevant mounting bolts to separate the pump body and clean away any incrustation. Re-prime the pump when returning to service. In the event that overhaul of the pump or motor is necessary, contact your Clarke service department.
