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.
• 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 30 mA MUST BE USED.
If you are not sure, consult a qualified electrician. DO NOT try to do any
repairs.

ASSEMBLY
Remove all packaging and make sure that the unit has no visible damage.
Dispose of all packaging appropriately.
FITTING THE ELBOW
1. Screw the elbow into the outlet
port as shown.
2. Connect a suitable hose (not
supplied) to the pump outlet.
• Suitable hoses are available
from your local Clarke dealer.
FITTING THE HOSE ADAPTER
A hose adaptor can be screwed
onto the elbow if required.
1. Trim the adaptor to the required
size.
• Reducing the hose diameter
will effect the maximum flow
rate.
2. Connect a suitable hose (not
supplied) to the pump outlet.
• Suitable hoses are available from your local Clarke dealer.
FOLDING BASE
The pump has three folding feet
fitted to the base.
• When the feet are in the closed
position, the space between
the base of the pump and the
supporting surface is reduced
to around 5 mm, limiting the
passage of solids in suspension.
when the feet are closed the
pump should only be used for
pumping clean water.
• When the feet are opened the pump can be used with solids in
suspension of up to a rated maximum of 30 mm in diameter.

SETTING UP THE PUMP
POSITIONING 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
vertically 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 50 x 50cm.
• ALWAYS raise and lower the pump using a rope attached to the lifting
handle.
• Take all necessary precautions as described on page 3.
USING THE PUMP
1. Connect the mains plug to the mains supply.
• Always use a high sensitivity residual current device (RCD) which has a
tripping current of less then 30mA.
2. Switch the mains power supply on.
• The pump will begin to drain water.
• As the water level falls, so will the float switch, until it stops the pump.
• You can adjust the position at which the float switch lead clips to the
side of the pump. Adjusting the length of the float switch lead will
change the depth of water at which the pump will turn on or off.
3. When pumping is finished, disconnect the pump from the mains power
supply.
IMPORTANT: Do not allow the pump to run dry.
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.
