If using this pump to pump out a garden pond,
please note that there is a small quantity of oil in
the pump seal. If the pump or seal is damaged,
possibly caused by running the pump dry, oil
may leak out, and appear as a film on the
surface of the water. Although harmless to
people, the oil must be cleared to prevent
any possible harm to pond life. Disconnect
the pump from the electrical supply,
remove it from the pond, and clear the
oil, then contact your CLARKE dealer for
advice.

ELECTRICAL CONNECTIONS
All models EXCEPT HSE 250A, should have their mains lead connected to a standard
230Volt (50Hz) electrical supply through an approved plug or a suitably fused
isolator switch. We recommend that these pumps be fitted with a Residual Current
Device (RCD).
NOTE: This is mandatory when pump is used for pumping swimming pools.
Model HSE250A must be connected to a protected 110V supply, through a suitably
approved connector. On no account must a 230V, 13amp (BS1363) 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.
If used for draining swimming pools or ponds, the pump MUST be fitted with a
Residual Current Device (RCD), with a rated residual operating current of no
greater than 30mA.
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in the mains lead are coloured in accordance with the
following code: Green & Yellow - Earth
Blue - Neutral
Brown - Live
As the colours of the flexible cord of this appliance may not correspond with the
coloured markings identifying terminals in your plug proceed as follows:
Connect GREEN & YELLOW coloured cord to plug terminal marked with a
letter “E” or Earth symbol “ “ or coloured GREEN or GREEN & YELLOW.
Connect BROWN cord to terminal marked with a letter “L” or coloured RED
Connect BLUE cord to terminal marked with a letter “N” or coloured BLACK
The fuse in the plug for this appliance must be rated at 13 amps.
If this appliance is fitted with a plug which is moulded onto the electric cable (i.e.
non-rewirable) please note:
1. The plug must be thrown away if it is cut from the electric cable. There is a
danger ofelectric shock if it is subsequently inserted into a socket outlet.
2. Never use the plug without the fuse cover fitted.
3. Should you wish to replace a detachable fuse carrier, ensure that the correct
replacement is used (as indicated by marking or colour code).
4. Replacement fuse covers can be obtained from your local dealer or most
electrical
5. The fuse in the plug must be replaced with one of the same rating (13 amps)
and this replacement must be ASTA approved to BS1362.
IMPORTANT: If in doubt, consult a qualified electrician.

FEATURES
The pumps are of rugged and durable construction, designed for long lasting
continuous operation, and the motor is provided with a built in overload protector.
Except for model HSEC 400A, the pumps should be used ONLY for pumping water,
or water containing small solids in suspension. NOT for pumping slurry, mud or heavily
polluted water.
The HSEC 400A is fitted with a Tungsten Carbide cutter, and is specially suited for
heavily polluted waste water and waste solids, such as sewage, light slurry, factory
waste etc.
Automatic Pumps, i.e. those fitted with a Float Switch, denoted by an ‘A’ suffix to
their model number, are suitable for permanent or semi-permanent installations,
eg. installations where it is necessary to maintain a water at a particular level.
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.
It is not recommended that these pumps be used for pumping drinking water, as
there is a remote possibility of water contamination due to leakage of pump
lubricant, should the pump malfunction.
INSTALLATION
The pumps are completely submersible, and should be placed in a vertical position,
on a solid flat surface. If this is not available, sit the pump on timber, or house
bricks, but ensure they are not likely to shift.
Automatic versions should be placed in a sump which has adequate dimensions
so as not to restrict the movement of the float switch.
Connect the outlet to the largest diameter hose possible, any restrictions will reduce
capacity, and put additional strain on the motor.
Take all necessary precautionsas described on page 2 before plugging in, and
switching ON.
SUITABLE HOSE, FOR ALL PUMPS, IS AVAILABLE FROM YOUR CLARKE DEALER

TROUBLESHOOTING
A. PUMP WILL NOT START
1. Manual type (i.e. without float switch)
1.1 Check to ensure Power is switched on.
1.2 Check fuse (consult an electrician if in doubt).
1.3 If extension lead is fitted, check connections (consult an electrician if in
doubt).
1.4 Internal thermal cut-out has not re-set. Leave for 5 minutes and try again.
1.5 The Impeller may be jammed. Disconnect from the mains supply, re
move the bottom strainer, and remove any objects that may be ob
structing the impeller. Replace the strainer and try again.
If the pump still fails to start, consult your CLARKE dealer for advice.
2. Automatic Type (with float switch)
2.1 Check all above.
2.2 Float switch may be jammed against side wall, or prevented from moving.
2.3 Water level too low - switch in OFF position.
B. PUMP WILL START BUT NOT PUMP
1. Water level too low.
2. Check to ensure strainer is not blocked.
3. Check to ensure impeller is not jammed as in 1.5 above.
4. Check to ensure impeller is not damaged, and replace if necessary.
5. The head may be too great, i.e. you are trying to lift the water too great
a distance for the pump to cope with. (See specification chart).
C. AUTOMATIC PUMP WILL 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.
MAINTENANCE
Check pump installation regularly to ensure the base inlet is clear of leaves or
other debris.
Note that 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 and disconnect
from the mains supply. Check for blockages and allow the motor to cool (at least
5 minutes) before attempting to re-start.
This pump should require no maintenance other than regular cleaning. If the pump
starts to show signs of wear or damage, contact your CLARKE dealer for advice.
Do not use the pump if there is any damage to the mains supply cable, or to the
float switch or its cable. Do not attempt to repair the pump yourself, as
