GENERAL SAFETY PRECAUTIONS
As with all machinery, there are certain hazards involved with its
operation and use. Exercising caution will reduce the risk of
personal injury.
WORK AREA
1. Keep the work area clean and well lit. Floors should always be kept clear.
Cluttered or dark areas invite accidents.
2. Keep children and bystanders away while operating the pump.
Distractions can cause loss of control.
3. Remember, the operator or user is responsible for accidents or hazards
occurring to other people or their property.
PERSONAL SAFETY
1. ALWAYS stay alert, watch what you are doing and use common sense
when operating this pump. Do not install the pump while you are tired or
under the influence of medication, drugs or alcohol. A moment of
inattention can result in personal injury.
2. Do not over-reach. Keep your proper footing and balance at all times
when positioning the pump.
3. NEVER direct the water discharge towards electrical wiring or equipment.
4. ALWAYS store the pump out of reach of children and do not allow persons
unfamiliar with these instructions to operate it.
5. NEVER direct the discharge flow towards another person.
6. ALWAYS thoroughly familiarise yourself with this pump & its operation and
follow all instructions in this manual.
7. ALWAYS ensure that the pump is properly positioned where necessary to

surrounding the pump is kept clear.
GENERAL USE AND CARE OF THE PUMP
1. An approved Residual Current Device (RCD) must be used when pumping
from ponds or swimming pools.
2. ALWAYS lift the pump using the handle and use a rope or chain attached if
necessary to lower it into the pit or excavation. Never lift or carry the
pump by the power cable or by the float switch cable.
3. NEVER use this pump if any part is damaged. Have it inspected and
repaired by your local Clarke dealer.
4. ALWAYS use an extension cable suitable for outdoor use when operating
outdoors. Using the correct cable reduces the risk of electric shock.

5
5. ALWAYS maintain the pump with care and keep it clean.
6. ALWAYS use an approved cable extension suitable for the power rating of
the pump (see specifications). The conductor size should also be at least
the same size as that on the pump, or larger. When using a cable reel,
always unwind the cable completely.
7. NEVER use for pumping flammable liquids or corrosive chemicals. These
pumps are designed to pump water only.
8. NEVER abuse the electrical cable. Never use the cable for pulling or
unplugging the pump Damaged or tangled cables increase the risk of

collapse.
12. NEVER modify this pump in any way. Use it only for the purpose for which it
is designed.
SERVICING & REPAIRS
1. ALWAYS have the pump serviced by your local CLARKE dealer, using only
identical replacement parts. This will ensure the safety of the pump is
maintained. The use of non standard parts could be hazardous.
2. NEVER attempt any repairs yourself. If you have a problem with the pump
contact your local CLARKE dealer.
3. ALWAYS disconnect the pump from the electrical supply before placing it
into, or removing from the water, and before any cleaning or
maintenance.
4. If the power cable becomes damaged, it must be replaced rather than
repaired.
Your CLARKE water pump has been designed to give long and trouble free
service. If, however, having followed the instructions in this booklet carefully,
you encounter problems, take the unit to your local CLARKE dealer.
Please keep these instructions in a safe place for future reference.

ELECTRICAL CONNECTIONS
WARNING! Read these electrical safety instructions thoroughly
before connecting the product to the mains supply.
Before switching the machine 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 230 VAC mains power. Connecting it to
any other power source may cause damage.
This product may be fitted with a non-rewireable plug. If it is necessary to
change the fuse in the plug, the fuse cover must be refitted. If the fuse cover
becomes lost or damaged, the plug must not be used until a suitable
replacement is obtained.
If the plug has to be changed because it is not suitable for your socket, or
due to damage, it should be cut off and a replacement fitted, following the
wiring instructions shown below. The old plug must be disposed of safely, as
insertion into a mains socket could cause an electrical hazard.
WARNING! The wires in the power cable of this product are
coloured in accordance with the following code:
Blue = Neutral Brown = Live Yellow and Green = Earth
If the colours of the wires in the power cable of this product do not
correspond with the terminal markings of your plug, proceed as follows.
• The wire which is coloured Blue must be connected to the terminal
which is marked N or coloured Black.
• The wire which is coloured Brown must be connected to the
terminal which is marked L or coloured Red.
• The wire which is coloured Yellow and Green must be connected to
the terminal which is marked E or or coloured Green.
Plug must be BS1363/A approved
Earth Always fit a 13 Amp fuse.
(Green and Yellow)

OVERVIEW
This CLARKE range of submersible pumps are suitable for discharging pools,
ponds, fountains, pits and any waste water drainage.
SUITABILITY
They can handle foul water containing suspended material including sand as
listed in the specification, and may be used for pumping water, (including
seawater) or water containing solids in suspension. The pumps are not
suitable for handling inflammable, corrosive, explosive or dangerous liquids.
THE FLOAT SWITCH
The float switch enables the pump to stop and restart automatically as the
surrounding water level changes. As the water level rises, the switch will float
and start the pump. As the water level falls, so will the float switch, until it stops
the pump. Float switches are factory set to provide the correct ON-OFF
switching mode. This makes them suitable for permanent or semi-permanent
installations, eg. installations where it is necessary to maintain water at a
particular level without an operator in attendance.
THE THERMAL CUT-OUT
The pumps are provided with a thermal overload cut-out, so that in the event
that the pump becomes overheated (due to becoming blocked etc.) it will
shut off automatically. When the blockage has been cleared, the thermal
cutout will cool down and re-set and the pump can be re-started.

OPERATION
CONNECTION AND LOCATION
1. Screw the outlet elbow and stepped adaptor supplied, onto the outlet of
the pump.
2. Connect the outlet adaptor to the largest diameter hose available, as any
restriction will reduce capacity and put unnecessary strain on the motor.
• The stepped adaptor fitting allows for connection of 32 mm (1¼”), 25 mm
(1”), or 19 mm hoses which should be secured with a hose clamp.
3. Ensure that the hose diameter is as large as possible if a long run of
discharge hose is being used.
4. Place the pump in a vertical position resting on a firm, flat surface. If this is
not available, sit the pump on timber or house bricks, but ensure they are
not likely to collapse. Never install the pump on sand, silt, mud or ground
that is likely to collapse.
5. Keep the pump clear of sediment
by standing it on a platform or
brick or suspending from a rope
attached to the handle if the
pump is to be used where there
may be silt or mud etc (e.g.
garden ponds).
6. Ensure the float switch has
sufficient room to operate
correctly if used in a confined
space such as a shaft or sump.
• The pump should only be placed
in a sump which is large enough
not to restrict the movement of
the float switch.
Note: When the pump is being
used in a permanent or semi-permanent installation, a check
valve should be fitted in the delivery hose. Suitable hoses and
valves are available from your Clarke dealer.

USING THE PUMP
1. Plug in the pump and switch on the power supply,
• The pump will only run where there is sufficient water for the float switch to
rise and activate the pump.
2. If required, the range of operation of the float switch can be manually
adjusted by positioning the float switch cable within the retaining clip at
the top of the pump. The switch will operate through its full range if left
hanging free.
3. Run the pump continuously or remove from the water and store in a frost
free location if the water is likely to freeze,
4. Never run the pump dry. Ensure the pump switches off when water has
stopped flowing.
• The pump should be able to clear water down to a residual depth of
approx 5mm, provided the float switch has been raised to keep the pump
running. In this situation, air and residual water may be seen escaping
from the vent valve.
5. Disconnect from the power supply when the water has been pumped
out. Avoid running the pump continuously if the discharge hose has
become obstructed and water is not flowing.
AUTOMATIC THERMAL OVERLOAD
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 at the mains supply. Check for blockages and allow the
motor to cool (at least 5 minutes) before attempting to restart, by which time
the cut-out will have reset.

CLEANING & MAINTENANCE
WARNING: MAKE SURE THAT THE PUMP IS DISCONNECTED FROM THE
POWER SUPPLY BEFORE CLEANING, OR PERFORMING MAINTENANCE.
The pump should require no maintenance other than regular inspection and
cleaning.
1. Inspect the pump prior to use and do not use the pump if there is any
damage to the mains power cable or to the float switch or its connecting
cable.
2. Check pump regularly to ensure the inlet is clear of leaves or other debris.
It can be cleaned out either by back-flushing or by removing the base
plate (after undoing the three retaining screws) and cleaning out by
hand.
3. If the pump has been used for pumping swimming pool water or salty
water likely to leave chemical residues, it should be flushed through with
clean water before storage.
4. Store in a dry place after use.
If the pump shows signs of wear or damage, contact your CLARKE dealer for
advice. Do not attempt to repair the pump yourself, as you may damage the
waterproof seals and invalidate your guarantee. Repairs should be carried
out by your local CLARKE dealer, or contact the CLARKE Service Department
on 020 8988 7400.
ACCESSORIES
A wide range of accessories is available from your nearest CLARKE dealer,
including hoses and hose adaptors.
