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.
• 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.

POSITIONING AND HOSE 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 hose to the outlet adaptor.
2. ALWAYS use the largest diameter hose possible as any restriction will reduce
capacity and put unnecessary strain on the motor especially if a long run
of discharge hose is being used.
• The outlet adaptor fitting allows for connection of 50 mm (2”) hose
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. 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.
4. 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.
5. 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.
• The pump will begin to drain water.
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 insert your fingers into the pump whilst it is connected to the mains.
7. NEVER use the submersible pump in a swimming pool when there are
people or animals in the pool.
8. Keep the pump clear of any sediment by standing it on a platform or brick
or suspending it at a suitable depth.
9. 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.
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 or by removing the base plate
(after undoing the retaining screws) and cleaning out by hand.
3. Take extra care to remove any debris from around the impeller.
4. 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.
5. 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.
6. 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
