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.

WARNING: READ THESE ELECTRICAL SAFETY INSTRUCTIONS

THOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE MAINS

SUPPLY.

WARNING: THE WIRES IN THE POWER CABLE OF THIS PRODUCT ARE

COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE:

BLUE = NEUTRAL BROWN = LIVE YELLOW AND GREEN = EARTH

Plug must be BS1363/A approved.

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 lower

end 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.

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

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 CBM250SS. 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.

These units operate as BOOSTER pumps by utilising an air chamber with a

pressure regulator to provide a constant pressure at the outlet.

The pump will automatically cut in when the water pressure reduces to 2.0 Bar,

and cut out when the pressure reaches 3.5 Bar. (These pressures are 3.5 and

5.2 bar respectively for Model CBM250SS). These pressures are factory set and

must not be altered. The pump may continue to operate for a short while,

after the tap is turned off, until the cut-out pressure is reached.

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

In order for the system to operate correctly it is necessary to pressurise the air

chamber to 1.5 Bar (22psi), which is carried out as follows:

Unscrew the large protection cap on the end of the air chamber to reveal the

air valve and use an air line or foot pump to charge the chamber to the

specified pressure, checking with a standard air pressure gauge until satisfied.

Remember to replace the protective cap when completed.

IMPORTANT: This procedure MUST be carried out BEFORE connecting to the

water supply.

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. 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.

NOTE: If a filter is fitted to your pump it is recommended that you remove

the brass plug on top of the unit and fill the bowl with water.

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.

3. 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:

• The inlet pipe is completely secure and completely free from

defects. Even a pin hole could prevent the pump from drawing

water. This is the most common problem encountered when

operating water pumps.

• 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.
