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. See the suggested
list on page 13.

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.

INSTALLATION 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 INSTALLATION

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.

Before switching the product on, make sure that the voltage of your electricity
supply is the same as that indicated on the rating plate. This product is
designed to operate on 230VAC 50Hz. Connecting it to any other power
source may cause damage.

PIPE/HOSE CONNECTIONS

The pump inlet and discharge ports
are both 1

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.

ADDITIONAL CONSIDERATIONS

SUCTION LIFT OR GRAVITY FEED

There are two possible methods of
pipework installation.

1. Suction Lift. Used to draw clean
water from a pool or well
providing the vertical distance
between the foot valve and the
pump does not exceed the 8
metres specified for this pump.

When suction lift is used it is essential
that all connections and hoses are
airtight or the system will not work
effectively.

A foot valve/filter fitted to the lower
end of the suction hose, (as
illustrated), is essential retain water in the system as the pump is not self
priming.

2. Gravity Feed. Used to draw water.
from a tank above ground.

PRIMING THE PUMP

Before using the pump for the first
time the inlet (suction) side must be

filled with water to prime the pump as
follows:-

1. With all inlet pipes/hoses, but no
outlet hose connected, pour
water into the outlet port until all
the air is expelled.

2. Connect the outlet hose to the
outlet port.

If the outlet hose is already connected, a priming port and threaded plug are
provided, adjacent to the outlet as shown.

NOTE: As the priming hole is quite small, it is recommended to fill the inlet

(suction) pipe with water before connecting to the pump, and
top up through the priming port once the pipe is connected. A
non-return valve will need to be fitted to the inlet pipe for this
purpose.

3. Switch on the pump.

• Water should start to flow through the system.

4. Check for leaks and make good if necessary.

5. Adjust any device such as a non-return valve, which may be fitted to the
outlet side of the pump, to maximise efficiency.

• Do not place any restriction on the inlet or discharge hoses.

• Remember - this pump is designed for pumping CLEAN WATER ONLY.

DO NOT USE for pumping chemicals or other flammable or corrosive
liquids.

OPERATION

1. Open any valves in the pipeline.

2. If operating the pump for the first time, prime the pump as described. on
page 8.

NOTE: Refilling (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.

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 pump 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.
