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.

This product may be fitted with a non-rewireable plug. If it is necessary to

change the fuse in the plug, the fuse cover must be refitted. If the fuse cover

becomes lost or damaged, the plug must not be used until a suitable

replacement is obtained.

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.

INSTALLATION OF THE PUMP

IMPORTANT: The pump MUST NOT be connected to the mains power supply

until all hose/pipe installations are completed.

These notes are for guidance on how to achieve a proper working system. If

any part of the system is to be connected to the mains water supply, ensure

that you comply with your local water authority regulations.

INSTALLATION LAYOUT

The pump must always be installed and operated in a horizontal position using

the fixing holes in the base to secure the pump firmly in its operating position.

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.

Typical pipework connections are

shown.

The suction lift i.e. the vertical

distance between the water level

and the pump, should not exceed

the distance specified for your pump.

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

any rigid metal pipework and the pump.

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.

PIPELINE FITTINGS REQUIRED

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 performance of your pump will be effected by the diameter of the inlet

pipe - any restriction will greatly reduce the flow. We recommend that you use

a diameter which is as large as practicable with a suitable reducer for

connection to the 1” BSP inlet adapter. The discharge hose should be

attached to the outlet adapter (not supplied).

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

A 1” BSP hose adapter will be required for connection

to the inlet and outlet port. These are available from

your CLARKE dealer.

A foot valve and filter should be fitted to the lower

end of the suction hose as illustrated, so as to help

retain water in the suction system and to prevent the

possibility of large foreign bodies arriving at the

pump/cartridge filter.

A gate valve may be installed in-line on the outlet

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.

THE INLET FILTER

An inlet filter is supplied with the

CBT1300SS pump. 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 and should hang vertically

when installed.

PREPARATION FOR USE

THE PRESSURE VESSEL

This unit operates as a booster pump

by utilising an air chamber with a

pressure regulator switch to provide a

constant pressure at the outlet. The

pump will automatically cut in when

the water pressure reduces to 1.4 Bar

and cut out when the pressure

reaches 3.5 Bar.

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

These pressures are factory set but can be adjusted using the plastic screw on

the pressure switch. The pump may continue to operate for a short while after

the supply valve is turned off until the cut-out pressure is reached.

In order for the system to operate

correctly it is necessary to pressurise

the air chamber to 3.5 Bar (50psi),

which is carried out as follows:.

Unscrew the protective cap on the

end of the air chamber to reveal the

air valve and use an air line or foot

pump to charge the pressure vessel

to the specified pressure.

Check the air pressure gauge until

satisfied and replace the protective cap when completed. This procedure

MUST be carried out before connecting to the water supply.

PRIMING THE PUMP

When suction lift is used to draw water into the pump it is essential that all

connections and hoses are completely air tight or the system will not work.

Although the pump is a ‘self priming’

type, it is still 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/repair. This

is carried out as follows:-

1. Remove the small filler plug on the

top of the pump chamber and 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 and fill the filter bowl with water.

2. Adjust any valves 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 quickly start to flow

through the system. If, depending upon the suction depth, water does not

flow, check to ensure:

• The inlet pipe is secure and free from defects. Even a pin hole could

prevent the pump from drawing water efficiently. This is the most

common problem encountered when operating water pumps.

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

• 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 or the

system will not work.

The pump should never be operated

with any delivery valve completely

closed.

The pressure gauge should be

monitored after initial operation to

ensure the pressure switch is

operating within the set parameters.

If the gauge rises above the switch’s

pre-set value, switch the pump off

and reset the switch.

CARE AND MAINTENANCE

Protect the pump and pipework from freezing as the formation of ice may

cause serious damage.

The only maintenance required is a regular inspection to ensure that debris is

not blocking the passage of water through the pump. Should sand, chemical

or other contaminants come into contact with the pump, flush through with

cold clean water as soon as possible.

Periodically unscrew the filter bowl and clean out the cartridge and interior of

any debris collected.

If you suspect the pump is blocked by 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

fastenings 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.
