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 which is

marked N or coloured

black.

• The BROWN wire must

be connected to the

terminal which is

marked L or coloured

red.

• The YELLOW AND

GREEN wire must be

connected to the terminal which is marked E or or coloured green.

An approved Residual Current Device (RCD) which has a tripping current of

less than 30mA must be used.

If you are not sure, consult a qualified electrician. DO NOT try to do any

repairs.

OVERLOAD SWITCH

These pumps are fitted with a thermal overload switch. If the pump overheats

for any reason, it will automatically switch the pump OFF. Once the pump has

cooled (at least 5-10 minutes), the pump will automatically restart.

USING THE PUMP

1. Using the adaptor if required,

connect a suitable hose (not

supplied) to the pump outlet.

• Suitable hoses are available from

your local Clarke dealer.

2. 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 50 cm.

• ALWAYS raise and lower the pump using a rope attached to the lifting

handle.

• Take all necessary precautions as described on page 3.

• The pump inlet must be fully submerged before the pump is switched on.

3. Connect the mains plug to a high sensitivity residual current device (RCD)

which has a tripping current of less then 30mA.

4. 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, If the length of the float switch lead is short the pump

will turn on and off earlier.

5. When the pumping is finished, disconnect the pump from the mains power

supply.

WARNING: CHECK THE PUMP FOR DAMAGE BEFORE USE, DO NOT USE THE

PUMP IF IT IS DAMAGED IN ANY WAY.

CAUTION: DO NOT ALLOW THE PUMP TO RUN DRY
