INSTALLATION OF THE PUMP
IMPORTANT: The pump MUST NOT be connected to the mains power supply
until all hose/pipe installations are completed.
INSTALLATION LAYOUT
The pump must always be installed and operated in a horizontal position using
the fixing holes in the base to secure it in position.
The illustration shows typical pipework
connection including an inlet filter and
hose adapters listed on page 16.
When mounting the pump on a raised
base it will be necessary to allow
clearance for the filter. Mount the
pump securely on blocks or a purpose
built platform to protect it from
flooding.
The suction lift i.e. the vertical distance
between the water level and the
pump, should not exceed the
distance specified.
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.
The pump is resistant to splashing from any direction but should on no account
become submerged. Ensure there is adequate air circulation around the
motor. The pump should be installed in a dry, well ventilated enclosure,
sheltered from rain and with an environment temperature not higher than
35°C.
Always place the pump as close as possible to the water to be pumped but
be positioned so as to avoid the possibility of immersion. The power supply
should also be a safe distance away. If in doubt, please contact your
electrician and refer to national regulations.
Ensure the pump & its power cable do not create a safety hazard for people
walking past it. The length of the power cable on the pump limits the distance
from the power source. If an extension cable is required, ensure it is
compatable with the cable supplied.

SUCTION LIFT OR GRAVITY FEED
SUCTION LIFT
It is possible to draw water up from a sunken pool or well.
GRAVITY FEED
The pump can draw water from an above ground tank.
PIPELINE FITTINGS REQUIRED
Because of the variety of possible installations, no plumbing accessories are
supplied with your pump. However, accessories designed specifically for this
pump are available from your CLARKE dealer.
The performance of your pump will be affected 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 delivery hose should be attached
to the outlet adapter (not supplied).
CONNECTIONS AND HOSES
In case of a fixed installation, it is recommended that you fit a non-return valve
on both sides of the pump. This allows closure of the line upstream and/or
downstream from the pump, useful for service and cleaning operations or for
periods in which the pump is not in use.
A 1” BSP hose adapter will be required for connection
to the inlet and outlet ports. 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.
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.

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.
It is 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.
2. Adjust any valves which may be fitted to the discharge 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.
• 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.
The pump should never be operated with any delivery valve or tap
completely closed.

THE CONTROL PANEL
The "Power On" indicator light
indicates that there is power to the
pump.
Press the "Reset" button to start the
pump running. It may also be that the
pump is in pressure holding and
stopped state. When the pressure on
the discharge side is lower than the
starting pressure, the pump will
automatically start pumping.
• The "Power On" indicator lamp
indicates that the pump is
pumping normally.
When the "Power On" indicator
flashes, it indicates that the pump is in the pressurised and stopped state and
there is pressure in the discharge pipeline. Pressing the "Reset" key is invalid.
When the water intake or the resulting pressure drops, the pump will restart.
• "Power On" indicator light will be illuminated.
When the "Pump On" light and "Failure" light are illuminated it shows that the
pump is pumping but there is no water in the pipeline. For example, there will
be no water for about 8 seconds.
• The pump will be in stopping state.
When the "Pump on" light and "Failure" light are illuminated, pressing "Reset"
key will restart the pump again. The pump will stop working because it is
indicated that there is a fault, which may be no water supply, filter mesh
blockage, water supply pipe leakage or pump parts damage. Check and fix
the problem according to "Troubleshooting".
• The "Power On" indicator light is illuminated
• The "Failure" indicator light flashes. (one second each time). At this
time, pressing the "Reset" key will be not work. Only after pulling out
the plug to correct the malfunction, can the power be reinstated to
start the pump. Indicate that there has been a fault and the pump
has stopped working. This may be a leak in the pressure line or the
pump headseal seal is leaking. The machine closes and opens
frequently to start protect the function.

START-UP
1. Plug the power cable into a 230 V power socket and switch on.
2. The pump motor will start and water will start to flow through the system.
There may be some delay before water is discharged, depending on the
depth of the water level in the well and the position of the discharge point.
3. Check for any leaks and correct as necessary.
• If the motor fails to start, or the pump does not deliver water, refer to
TROUBLESHOOTING on pages 12-13. Never operate the pump when
not primed with water or if the inlet is blocked.
4. To stop the pump, switch off and remove the plug from the power socket.
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, contact your Clarke dealer for
overhaul.
2. In the event of a blockage, where debris has entered the suction
chamber, it can be cleaned out as described under MAINTENANCE.
3. Should contaminants come into contact with the pump, flush through with
cold water as soon as possible to prevent damage. DO NOT USE for
pumping chemicals or other corrosive liquids (other than pool purification
chemicals in their correct mix ratio).
4. If the pump is being used to drain a pool or pond, 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.
AFTER USE
If the pump will not be used over the winter period, or whenever 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 installed in a clean, dry environment sheltered
from the weather. In the event that dismantling and overhaul of the pump is
necessary, contact your CLARKE service department.
CAUTION: DO NOT START THE PUMP WITHOUT HAVING COMPLETELY
FILLED IT WITH WATER,

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.
