ELECTRICAL CONNECTIONS
Their mains lead should be connected to a standard 230Volt (50Hz) electrical supply through
an approved plug or a suitably fused isolator switch. We strongly recommend that these
pumps be fitted with a Residual Current Device (RCD).
NOTE: This is MANDATORY when pump is used for pumping swimming pools and ponds
If the pump is to be connected to an outdoor electrical supply, make sure that both the
plug and the socket are of a BS approved waterproof design.
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 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
FUSE RATING
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 of
electric 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
outlets
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 you are in any doubt regarding electrical installation,
you should consult a qualified electrician.

FEATURES
This pump is of rugged and durable construction, designed for long lasting
operation and its plastic body provides good anti corrosive properties. The motor
is provided with built in overload protection.
For your information the chart, on page 9 shows the flow rate for the pump at
various heads. HEAD is the distance, or height, from the surface of the water to
the point of discharge)
This pump is designed to pump clean water such as fish ponds, swimming pools,
flooded cellars etc.
IMPORTANT:
The Pump is NOT designed for pumping slurry, sludge, mud or heavily polluted
water, and should NOT be used for PERMANENT INSTALLATION in fish ponds or any
water containing chemicals or other acidic contaminants including salt water.
Whenever the pump is used to pump contaminated water, e.g. to drain fish ponds
etc., you must ALWAYS immerse it in clean water and run it for a few minutes on
completion, to ensure it is completely cleansed of all contaminants.
The maximum depth to which this pump should be submerged is 8 Metres.
This pump is suitable for permanent or semi-permanent installations, e.g.
installations where it is necessary to maintain a water at a particular level.
As the water level rises, so will the float. At a certain point the switch will operate
and start the pump. As the water level falls, so will the float until the switch operates
again and stops the pump.
You can adjust the level at which the
pump cuts out by sliding the float switch
cable through the slots in the handle.
Shorten or lengthen it as required. The
shorter it is, the earlier the pump will cut
out, and the water therefore will be
deeper at this point. Similarly, it will cut in
earlier and the water will therefore be
shallower when it does so.
ALWAYS check its operation before use.
Theoretically, the pump will drain a sump down to a depth of 5mm, but this will
depend upon the float switch setting.
You should never allow the pump to operate for longer than 10 minutes with the
pump body exposed....that is....when the water level is below 70mm.
The pump is provided with a vent valve in order to prevent an air lock when
plunging the pump into the water. It may take up to 1 minute before all air is
expelled, once the pump is submerged.

INSTALLATION and OPERATION
The pump is complete with an Outlet Hose Adapter which simply screws into the
outlet port on the side of the pump body.
The adapter has three steps, providing the option for three differnt hose sizes to
be used. (See specifications for details).
Please bear in mind, that if the pump is to be used for drainage purposes, or in
situations that demand maximum efficiency, you shouls ALWAYS connect the
largest diameter hose possible to the outlet hose adapter, as small diameter hoses
reduce capacity and put additional strain on the motor.
Once you have decided upon a suitable hose size, the smaller diameter steps of
the addapter should be cut off, so as not to cause an obstruction to flow. If you
subsequently need to install a larger diameter hose, replacement adapters are
available from your Clarke dealer.
Ensure the hose is secured with a suitable worm drive clip (not supplied).
The pump is completely submersible and must be placed in a vertical position on
a solid flat surface. If this is not available, sit the pump on house bricks, or something
similar, and ensure that this type of support is not likely to shift.
The pump should be well clear of silt, mud or any type of marine growth.
IMPORTANT:
ALWAYS raise and lower the pump using a rope attached to the handle,
NEVER by the power cable or float switch cable.
Ideally the pump should be placed in a sump which has adequate dimensions so
as not to restrict the movement of the float switch.
Please note that the symbol on the pumps’ Rating Plate, denotes the MAXIMUM
depth to which the pump may be submerged, in metres.
With the pump properly installed, and taking all necessary precautions as described
on page 3, plug in to the mains supply, and switch ON.
Note:
If the pump does not deliver immediately, it is possible that an air lock exists.
Leave the pump for approximately one minute in order for air in the pump to vent
through the vent valve. If necessary, switch ON and Off again in order to assist the
venting process.
SUITABLE HOSE, and SPARE/REPLACEMENT HOSE ADAPTERS ARE AVAILABLE

MAINTENANCE
WARNING
Before checking the condition of the pump, ensure it is unplugged from the
mains supply. If the unit is hard wired, ensure the circuit breaker is open.
Check the pump installation regularly to ensure the base inlet is clear of leaves or
other debris.
Note that the pump is fitted with an automatic thermal overload protection
device. If the pump overheats due to an obstruction in the pump, or pumping
warm water in excess of 35oC 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 15 minutes) before attempting to restart.
The pump should require no maintenance other than regular cleaning. If it 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 you may damage the waterproof
seal and invalidate your guarantee. Repairs must be carried out by your CLARKE
dealer, or contact the CLARKE Service Department, on 0208 8988 7440.
If the pump becomes badly clogged, back flush by removing the outlet hose
adapter and directing a jet of clean water through the outlet port.

TROUBLE SHOOTING
A. PUMP WILL NOT START
1 Float switch may be jammed against side wall, or prevented from moving.
2 Water level too low - float switch in OFF position - Lift float to check switch.
B. PUMP WILL START BUT NOT DELIVER
1. Check to ensure strainer is not blocked.
2. Discharge tube clogged or obstructed.
3. 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 specifications pages 9 -10 ).
4. Impeller may be damaged - Consult your CLARKE dealer
5. Air lock in system. Switch OFF and ON again to deaerate the system
C. 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.
D. PUMP STOPS RUNNING
1. Thermal overload has operated. If this condition persists, investigate the cause.
Are you attempting to pump liquid which is too heavy for the pump (mud, slurry
etc.) or a foreign object has jammed the impeller.
2. Float switch has cut in.
3. No electrical supply....investigate cause. i.e.check fuse/RCD/Circuit breaker etc.
