INTRODUCTION
Thank you for purchasing this CLARKE submersible pump.
The CLARKE range of submersible pumps are suitable for discharging pools,
ponds, fountains, pits and any waste water drainage. They can handle foul
water containing suspended material as stated in the specification. The
pumps are not suitable for handling inflammable, corrosive, explosive or
dangerous liquids. The pump is water-cooled and does not contain any oil.
The ‘Pump Performance Curve’ graph shown, displays the characteristics
graphically and describes the relation between the flow-rate and the head
for the pump.
The pump is 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.
Before attempting to use this product, it is essential that you read this manual
thoroughly and carefully follow all instructions given. In doing so you will ensure
the safety of yourself and that of others around you, and you can also look
forward to the product giving you long and satisfactory service.

ELECTRICAL CONNECTIONS
Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply
through an approved 13 amp BS 1363 plug, or a suitably fused isolator switch.
If the plug has to be changed because it is not suitable for your socket, or
because of damage, it must be removed and a replacement fitted, following
the wiring instructions shown below. The old plug must be discarded safely, as
insertion into a power socket could cause an electrical hazard.
If the colours of the wires in the power cable do not agree with the markings
on the plug proceed as follows
• 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.
AN APPROVED RESIDUAL CURRENT DEVICE (RCD) WHICH HAS A TRIPPING
CURRENT OF LESS THAN 30MA MUST BE USED.

POSITIONING AND CONNECTION
Remove all packaging and make sure that the unit contains no visible
damage. Dispose of all packaging appropriately.
CONNECTING THE PUMP
1. Connect the outlet adaptor to the largest diameter hose available, as any
restriction will reduce capacity and put unnecessary strain on the motor if
a long run of discharge hose is being used.
• The adaptor fitting allows for connection of 51 mm (2”) hoses which
should be secured with a hose clamp.
• Suitable hoses are available from your local CLARKE dealer.
POSITIONING THE PUMP
1. It may be safer to raise and lower the pump into deep water using a rope
attached to the lifting handle.
2. Place the pump in a vertical position resting on a firm, flat surface in the
area that you want to drain. If there is sediment in the operating area, the
pump should be placed vertically on house bricks, or similar but ensure
they are not likely to collapse. Never position the pump on sand, silt, mud
or ground which is likely to collapse.
3. 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).
4. Route the hose as straight as possible. Excessive bending of the hose could
obstruct the flow of water, reduce the pumping volume or clog the pump
with mud, thus disabling the pumps function. If the hose is kinked at its base
it will create air pockets in the pump, causing it to operate in a partially dry
state. Take care to straighten any kinks or bends in the hose.
5. Do not operate the pump if the water is too shallow. This will be below the
level of the outlet elbow with the impeller fully immersed.
6. Allowance must also be made for the overall width of the pump including
the outlet elbow on one side.
• When the pump is being used in a permanent or semi-permanent
installation, a non-return valve should be fitted in the delivery hose.
Suitable hoses and valves are available from your CLARKE dealer.
• Take all necessary precautions as described on pages 4-5.
• The pump inlet must be fully submerged before being switched on.

USING THE PUMP
1. Plug in the pump and switch on the power supply.
• Suitable hoses are available from your local CLARKE dealer.
2. Run the pump continuously or remove from the water and store in a frost
free location if the water is likely to freeze.
3. NEVER run the pump dry. Ensure the pump is switched off when water has
stopped flowing.
• The pump should be able to clear water down to a residual depth of the
inlet port, In this situation, air and residual water may be seen escaping
from the discharge hose.
4. 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.
5. Disconnect the pump from the mains supply before placing it into or
removing it from the water.
6. NEVER carry the pump by the power cable. Always use the handle or a
rope tied securely to the handle.
7. NEVER insert your fingers into the pump whilst it is connected to the mains.
8. 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.
OVERLOAD PROTECTION
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) by which time the cut-out will have reset.
Once the pump has cooled the pump will automatically restart.
WARNING: CHECK THE PUMP FOR DAMAGE BEFORE USE, DO NOT USE THE
PUMP IF IT IS DAMAGED IN ANY WAY.

CLEANING, MAINTENANCE & STORAGE
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.
2. Check pump regularly to ensure the inlet is clear of leaves or other debris. It
can be cleaned out either by back-flushing 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. When the pump is not being used for extended periods, clean and dry it
thoroughly and store in indoors. if the pump is left in water, it should be run
at least once a week to prevent it from seizing up.
5. 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.
WARNING: MAKE SURE THAT THE PUMP IS DISCONNECTED FROM THE
POWER SUPPLY BEFORE CLEANING OR PERFORMING MAINTENANCE
