WATER CONNECTIONS
IMPORTANT: The pump must not be connected to the power supply until the
hose/pipe installation is 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, (except for the Handy Pump 2, which is provided
with a 4 metre inlet hose complete with a foot valve and filter). However,
accessories designed specifically for this range of pumps are available from your
CLARKE dealer and are listed on page 30.
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. (Not
applicable to the Handy Pump 2, which is portable). 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. (See
Specifications, pages 9 to 11).
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 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 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.
NOTE: The Handy Pump 2 is provided with a 4 metre inlet hose
complete with a foot valve and filter
.
The delivery hose should be attached to the outlet adapter which is supplied.
IMPORTANT: In the case of the CBM250SS model, the hose MUST rise vertically
for 70cm before elbows are connected.
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 these pumps 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 pumps CBM240,
CBM240E & CBM250SS. A filter specifically designed for all pumps in the range is
available from your CLARKE dealer - see Accessories on page 30.
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.
CPE100TF, CBM100SS, CBM130SS, CBM250SS and CBM240E.
These pumps are set up as BOOSTER PUMPS, described in greater detail below, and
are provided with non-return valves. Additionally, 100TF & 240E models are provided
with filters, (optional accessories for SS models - see your Clarke dealer for details).
Non-return valves and filters are connected to the inlet port as follows:
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.
CBM240E
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.

CPE100TF, CBM100SS, CBM130SS and CBM250SS
These units are set up as a BOOSTER pumps by utilising an air chamber with a pressure
regulator to provide a constant pressure at the outlet. All models are provided with
non-return valves and Model CPE100TF is also provided with an inlet filter.
The pumps 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.
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 protection 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. 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.
In the case of the CPE100P, no filler plug is provided, and the pump body is
therefore filled through the outlet port before its’ connection
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:
a) 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.
b) 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.
