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.
