SUBMERSIBLE WATER PUMP

Thank you for purchasing this Clarke Submersible Pump.

This highly efficient pump is designed for pumping clean water only, please see Features,

page 5), and are ideally suited for draining ponds, pools, building excavations etc,

where water temperature does not exceed 35°C.

These pumps are NOT suitable for pumping salt water, or for permanent installation in fish

ponds as the acidity, found in fish ponds, will damage the pump seals.

Before attempting to operate your pump, please read this instruction manual thoroughly

and follow all directions carefully. This is for your own safety and that of others around you,

and to help you achieve long and trouble free service from your pump.

the water and stored in a frost free location.

10. If the pump is to be used where there may be silt or mud (e.g., garden ponds), keep

the pump clear of any sedimentby standing it on a platform or brick or suspending

from a rope attached to the handle.

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.
