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.
WARNING: THE WIRES IN THE POWER CABLE OF THIS PRODUCT ARE
COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE:

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).

7
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
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.

8
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
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.

9
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
• 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.
