OVERVIEW
SUITABILITY
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 listed in the specification. 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 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.

CONNECTION AND POSITIONING
1. Screw the outlet elbow and
stepped adaptor supplied, onto
the outlet of the pump as shown.
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.
• Suitable hoses are available
from your local Clarke dealer.
POSITIONING THE PUMP
1. ALWAYS raise and lower the pump
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 install the pump on sand, silt, mud or ground that 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. Ensure the pump is positioned with adequate space so that the movement
of the float switch is not restricted - recommended minimum area of 50 x
50cm.
5. Allowance must also be made for the overall width of the pump including
the outlet elbow on one side.

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.
• 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.
USING THE PUMP
1. Plug in the pump and switch on the power supply.
• Always use a high sensitivity residual current device (RCD) which has a
tripping current of less then 30mA.
• 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 & 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 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 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. 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.
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.
WARNING: MAKE SURE THAT THE PUMP IS DISCONNECTED FROM THE
POWER SUPPLY BEFORE CLEANING OR PERFORMING MAINTENANCE
