SAFETY PRECAUTIONS
1. These pumps are designed to pump WATER ONLY. Never use for pumping
flammable liquids or chemicals.
2. Never run the pump dry.
3. An approved Residual Current Device (RCD) which has a tripping current
of less than 30mA must be used when pumping from ponds or swimming
pools.
4. Never carry the pump by the mains lead or float switch.
5. Never pull the mains lead to disconnect the pump from the mains socket.
6. Your submersible pump may only be used for pumping water from a
swimming pool when there is no person or animal in the pool.
7. Always disconnect the pump from the electrical supply before placing it
into, or removing it from the water and before any cleaning or
maintenance.
8. Always use the moulded handle (or lifting eye), with a rope or cable
attached when lifting the pump. NEVER lift the pump by the mains cable,
or, where fitted, the float switch cable.
9. DO NOT run the pump with the body exposed for longer than 10 minutes.
10. DO NOT install the pump on sand or ground which is likely to shift.
11. Do not use the pump if the water is liable to freeze, as this can cause
damage to the pump. Remove the pump from the water and store it in a
frost free location.
12. If the pump is to be used where there may be silt or mud (for example,
garden ponds), keep the pump clear of any sediment by standing it on a
platform or brick.
13. Do not allow children to touch the pump, cables or connections.
14. Disconnect the pump from the mains supply when not in use.
15. Have the pump repaired by a qualified person.
16. Keep the mains cable away from heat, oil and sharp edges.
17. Always check the plug, mains cable and float switch cable for damage
before use. Do not use the pump if damaged. Refer to qualified service
personnel for repair.
18. If you have to use an extension lead with this product, it must be designed
for outdoor use and incorporate a cable suitable for use with Class I
appliances.

ELECTRICAL CONNECTIONS
Connect the mains lead to a suitable 110 Volt (50Hz) electrical supply through
an approved plug or a suitably fused isolator switch, or to a suitable portable
110 volt transformer.
We recommend that this pump is fitted with a Residual Current Device (RCD).
If the pump is to be connected to an outdoor electrical supply, ensure both
the plug and the socket are of a British Standard approved waterproof design.
The wires in the mains lead are coloured according to with the following code:
Green & Yellow - Earth
Blue - Neutral
Brown - Live
As the colours of the flexible power cable of this appliance may not
correspond with the coloured markings identifying terminals in your plug
proceed as follows:
• Connect GREEN & YELLOW wire to the terminal marked with a letter “E” or
Earth symbol ‘ ’or coloured GREEN or GREEN & YELLOW.
• Connect BROWN wire to terminal marked with a letter “L” or coloured RED
• Connect BLUE wire to terminal marked with “N” or coloured BLACK
IMPORTANT: If you are in any doubt regarding electrical installation, you should
consult a qualified electrician.

PREPERATION
CONNECTING THE MULTI HOSE ADAPTOR
1.
ELBOW
Fit the elbow adaptor to the
pump outlet as shown in the
diagram opposite.
2. Screw the multi hose adaptor
onto the elbow.
• The multi hose adaptor is
capable of accepting 1”,
¾”and ½” hoses.
3.
1”
¾”
½”
Simply cut the multi hose
connector to the required size
and attach a suitable hose using
with a worm drive clip.
• For maximum efficiency, we
strongly recommend that you
connect a 1½” diameter hose
to the multi hose adapter.
• Alternatively, you may remove
the multi adapter altogether,
and screw on a 1½” BSP hose adapter.
The pump is completely submersible and should be placed in a vertical
position on a solid flat surface, placing the pump on a couple of house bricks if
required.
SUITABLE HOSES AND SPARE/REPLACEMENT MULTI HOSE ADAPTERS ARE
AVAILABLE FROM YOUR CLARKE DEALER.
WARNING: DISCONNECT THE PUMP FROM THE MAINS POWER SUPPLY
BEFORE CONNECTING THE MULTI HOSE ADAPTOR.

USING THE PUMP
1. Place the pump on a flat surface in the area that you want to drain.
• If there is sediment in the operating area, the pump should be
placed on house bricks or similar.
• Ensure the pump is positioned with adequate space so that the
movement of the float switch is not restricted - recommended
minimum area of 40 x 40cm.
• ALWAYS raise and lower the pump using a rope attached to the
lifting handle.
• Take all necessary precautions as described on page 3 before
plugging in and switching ON.
2. Connect the mains plug to a high sensitivity residual current device (RCD)
which has a tripping current of less then 30mA.
3. Switch the mains power supply on.
• The pump incorporates a float switch, which automatically switches
the pump ON when the water is above a pre-determined level.
• The pump will begin to drain water.
• As the water level falls, so will the float switch until it stops the pump.
4. Disconnect the pump from the mains power supply when finished.
• These pumps are fitted with automatic thermal overload protection.
If the pump overheats due to an obstruction in the pump or
pumping warm water for example, it will shut off automatically.
Switch the pump OFF and disconnect from the mains supply. Check
for blockages and allow the motor to cool (at least 5 minutes)
before attempting to re-start.
WARNING: CHECK THE PUMP FOR DAMAGE BEFORE USE. DO NOT USE THE
PUMP IF IT IS DAMAGED IN ANY WAY.
WARNING: THE WATER BEING PUMPED WILL BE POLLUTED IF THIS PUMP
BECOMES DAMAGED AND LUBRICANT WITHIN THE PUMP ESCAPES.
WARNING: NEVER CARRY THE PUMP USING THE MAINS POWER CABLE.
DAMAGE TO ELECTRICAL CABLES CAN BE HAZARDOUS . ALWAYS USE THE
HANDLE WHEN MOVING THE PUMP.
CAUTION: DO NOT ALLOW THE PUMP TO RUN DRY

MAINTENANCE
These pumps should require no maintenance other than regular cleaning.
If the pump starts to show signs of wear or damage, contact your CLARKE
dealer for advice.
• Do not use the pump if there is any damage to the mains supply
cable or to the float switch or its cable.
• Do not attempt to repair the pump yourself, as you may damage
the waterproof seal and invalidate your guarantee. Repairs must be
carried out by your CLARKE dealer or contact the CLARKE Service
Department on 020 8988 7400.
• If the troubleshooting on page 8 does not solve your problem,
please contact the Clarke service department.
CLEANING
1. Check the pump installation regularly to ensure the base inlet is clear of
leaves or other debris.
• These pumps have screwless fittings at
their base, allowing the removal of the
plastic cover by prising the two
release clips apart in the direction of
the arrows.
• This allows better access to the cavity
at the bottom, should the pump
become badly clogged. Flush the
cavity and the impeller housing with
clean water.
• To replace the cover, ensure the
release clips line up with the holes on the base of the pump and
press the cover home.
NOTE: Do not attempt to strip the pump further as this will invalidate the
guarantee.
WARNING: BEFORE CHECKING THE CONDITION OF THE PUMP, ENSURE IT
IS UNPLUGGED FROM THE MAINS SUPPLY. IF THE UNIT IS HARD WIRED,
ENSURE THE CIRCUIT BREAKER IS OPEN.

TROUBLESHOOTING
PROBLEM SOLUTION
PUMP WILL
NOT START
1. Check to ensure power is switched on.
2. Check fuse (consult an electrician if in doubt).
3. If extension lead is fitted, check connections (consult an
electrician if in doubt).
4. Internal thermal cut-out has not re-set. Leave for 5
minutes and try again.
5. The impeller may be jammed. Disconnect from the mains
supply, remove the bottom strainer, and remove any
objects that may be obstructing the impeller. Replace
the strainer and try again.
6. If the pump still fails to start, consult your CLARKE dealer
for advice.
7. Float switch may be jammed against side wall, or
prevented from moving.
8. Water level too low - float switch in OFF position - lift float
to check switch.
PUMP WILL
START BUT NOT
PUMP
1. Check to ensure strainer is not blocked.
2. Discharge tube clogged or obstructed.
3. The head may be too great, i.e. you are trying to lift the
water too great a distance for the pump to cope with.
(See specification chart page 2).
4. Air bubble in the pump, produced during the plunge.
Plunge the pump again, at an angle, and shake it whilst
lowering to remove any air trapped in the system.
5. Impeller may be damaged - Consult your CLARKE dealer.
PUMP WILL
NOT STOP
1. Float switch may be prevented from moving to the fully
down position.
2. Float switch may be faulty. Consult your CLARKE dealer
for advice.
PUMP STOPS
RUNNING
1. Thermal overload has operated. If this condition persists,
investigate the cause. Are you attempting to pump liquid
which is too heavy for the pump (mud, slurry etc.)
2. Pump has run dry, or float switch has cut in.
3. A foreign object has jammed the impeller.
