MUST be used for all operations.
3. The electrical supply must be the
same as that on the rating plate.
4. Always make sure that your
hands are dry when connecting
or disconnecting from the mains
supply.

ELECTRICAL CONNECTIONS
We recommend that these pumps MUST be fitted with a Residual Current
Device (RCD), with a rated residual operating current of no greater than
30mA. This is mandatory when pump is used for pumping swimming pools
HSEC1400A + HSEC650A should have their mains lead connected to a
standard 230 volt (50Hz) electrical supply through an approved plug or a
suitably fused isolator switch.
As the colours of the flexible cable of this appliance may not correspond with
the coloured markings identifying terminals in your plug proceed as follows:
• 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.
HSEC651A must be connected to a protected 110V supply, through a
suitably approved connector. On no account must a 230V, 13amp plug be
used.
NOTE: If a portable 110V transformer is used, make sure it has a rated
capacity sufficient to take the load of the pump.
In the event that the pump is hard-wired into the electrical system, it must be
carried out in accordance with IEE regulations.
WARNING: READ THESE ELECTRICAL SAFETY INSTRUCTIONS
THOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE MAINS
SUPPLY.
WARNING: THE WIRES IN THE POWER CABLE OF THIS PRODUCT ARE
COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE:

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 vertically on a flat
surface in the area that you want to
drain.
• If there is sediment in the area,
place the pump 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.
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.

• You can adjust the position at
which the float switch lead is
held to 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.
5. When the pumping is finished,
disconnect the pump from the
mains power supply.
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), it will automatically restart.
CAUTION: DO NOT ALLOW THE PUMP TO RUN DRY

NOT STOP
1. Float switch may be prevented from moving to the fully
down position.
2. Float switch may be faulty. Consult your CLARKE dealer
for advice.
