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.
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. and it has been primed.
POSITIONING 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 CONNECTION
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.

ELECTRICAL CONNECTIONS
Before switching the pump on, make sure that the
voltage of your electricity supply is the same as that
indicated on the rating plate or on the junction box
cover on top of the motor. This product is designed
to operate on 230VAC 50Hz. Connecting it to any
other power source may cause damage.
Installation should be carried out by a qualified
electrician, using I.E.E approved cable and fittings,
and in accordance with I.E.E. Regulations. However,
in the further interests of safety we would emphasise
the electrical hazard
.
• The BLUE wire must be
connected to the
terminal marked N or
coloured black.
• The BROWN wire must
be connected to the
terminal marked L or
coloured red.
• The YELLOW AND
GREEN wire must be
connected to the
terminal marked E
or or coloured green.
We strongly recommend that this machine is connected to the mains supply
via a Residual Current Device (RCD).
If in any doubt, consult a qualified electrician. DO NOT attempt any
connections yourself.
WARNING! READ THESE ELECTRICAL SAFETY INSTRUCTIONS
THOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE
MAINS SUPPLY.
WARNING: WIRES IN THE MAINS LEAD ARE COLOURED IN
ACCORDANCE WITH THE FOLLOWING CODE:
GREEN/YELLOW = EARTH, BLUE = NEUTRAL, BROWN = LIVE.

PIPE/HOSE CONNECTIONS
The pump inlet and discharge
ports are both 1½” BSP (38 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.
These notes are for guidance on
how to achieve a proper working system. The diagram (Fig. 1) above shows a
typical installation at the pump.
A foot valve and filter should be fitted to the lower end of
the suction hose, as illustrated in Fig. 2, so as to retain water
in the suction system and more importantly, to prevent the
possibility of large foreign objects entering the pump body.
FURTHER 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 1½” (38 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.

•WARNING:-DO NOT place any such obstruction on the suction side
(inlet Port) of the pump unless it is an isolator valve in a gravity fed
system. It is also IMPORTANT to note, that these pumps should not be
operated with the delivery valve completely closed.
• If there is any chance of freezing, protect the pump and pipework
with suitable lagging. The formation of ice may cause serious
damage.
IMPORTANT: The pump MUST NOT be connected to the mains supply until all
hose/pipe installation is completed. DO NOT RUN THE PUMP DRY
NOTE: If any part of the system is to be connected to the mains water
supply ensure that local water authority regulations are observed.

OPERATION
1. Open any valves in the pipeline.
2. If operating the pump for the first time, prime the pump as described.
NOTE: 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 as necessary.
• 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 essential that a non-return valve be fitted to the
end of the suction pipe.
4. Stop the pump by switching off the power supply.
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.

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.
All electrical connections should be inspected regularly for signs of corrosion
and cleaned where necessary. It is advisable to apply a film of silicon grease
on the terminals for added protection.
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 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.
