Thank you for purchasing this Clarke Submersible Pump.

These highly efficient pumps are designed for pumping clean water, or water containing

sand or solids in suspension, (please see Features, page 5), and are ideally suited for draining

ponds, pools, building excavations etc., where water temperature does not exceed 50°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.

SAFETY PRECAUTIONS

1. These pumps are designed to pump WATER ONLY. Never use for pumping flammable

liquids or chemicals of any kind.

2. Never run the pump dry.

3. An approved Residual Current Device (RCD) MUST be used when pumping from ponds

or swimming pools.

4. Your submersible pump may ONLY be used for pumping water from a swimming pool

when there is no person or animal in the pool.

5. Always disconnect the pump from the electrical supply before

placing into, or removing from the water, and before any

cleaning or maintenance of the pump.

6. Always use the handle, with a rope or chain attached

when lifting the pump. NEVER lift thepump by the mains

cable, or, where fitted, the float switch cable.

7. DO NOT run the pump with the body exposed for longer

than 10 minutes.

8. DO NOT install the pump on sand, silt, mud etc., or

ground which is likely to shift.

9. If pumping water which is below 0oC, the pump MUST be

run continuously, otherwise the pump must be removed from 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

All models 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 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

These pumps are of rugged and durable construction, designed for long lasting

continuous operation and their stainless steel bodies provide good anti corrosive

properties. The motor is provided with built in overload protection.

For your information the charts, on pages 9 and 10, show the flow rate for each

pump at various heads. (HEAD is the distance, or height, from the surface of the

water to the point of discharge)

These pumps are designed to pump water containing solids in suspension. That is -

with a maximum of 5% solid content, and a maximum 3mm solid dia.

They are 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 the pump 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 these pumps should be submerged is 5 Metres.

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,

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.

Float switches are adjusted at the factory to provide the correct ON-OFF switching

mode, i.e. cut out when the depth of water is 40mm and will cut in again when

the level reaches 300mm.

You can adjust the level at which the pump cuts out by sliding the float switch

cable through the clip attached to the main body. Shorten or lengthen it as the

case may be. 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.

It should not normally be necessary to change the length of cable (from the clamp

to the float switch), but should you do so, remember that the cable length should

NEVER be so long that the float switch fails to operate and switch the pump OFF.

ALWAYS check its operation before use.

INSTALLATION

All pumps are complete with an Outlet Hose Adapter which simply screws into the

outlet port on top of the pump body.

Model CS85 is provided with a 1”BSP threaded adapter which will accept a 1”

I.D. hose.

Models CS120 and 185 are provided with a 1¼”BSP threaded, two stage adapter,

which will accept either a 1” or 1 ¼” I.D. hose.

Models CS240 and 305 are provided with a 1½” BSP threaded adapter which

will accept a 1½” I.D. hose.

Ensure the hose is secured with a suitable worm drive clip (not supplied).

If the pump is to be used for drainage purposes, or in situations that demand

maximum efficiency, we strongly recommend that you connect the largest

diameter hose possible to the outlet hose adapter, as small diameter hoses reduce

capacity and put additional strain on the motor.

If a 1¼” hose is used with models CS120 & 185, it will be necessary to cut off the 1”

diameter fitting at the joint between the two. Do not slide the 1¼” hose over the

1” fitting as the 1” fitting will act as a restriction.

The pumps are 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 lifting eye,

where fitted, or to the lifting handle, NEVER by the power cable.

Automatic versions 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 symbo on the pumps’ Rating Plate, denotes the MAXIMUM

depth to which the pump may be submerged, in metres.

Take all necessary precautions as described on page 2 before plugging in, and

switching ON.

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 these pumps are fitted with automatic thermal overload protection. If

the pump overheats due to an obstruction in the pump, or pumping warm water

in excess of 50oC 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.

These pumps 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 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 556 4443.

If the pump becomes badly clogged, the stainless steel strainer may be removed

and cleaned by removing the screws, on the underside of the strainer, which

secure it to the main body.

Back flush the pump by removing the inlet hose adapter and directing a jet of

clean water through the inlet port.

IMPORTANT

Do not attempt to strip the pump further as this will invalidate the guarantee

TROUBLE SHOOTING

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 cutout has not reset. Leave for 5 minutes and try again.

1.5 The Impeller may be jammed. Disconnect from the mains supply, remove

the bottom strainer and remove any objects that may be obstructing 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 - float switch in OFF position - Lift float to check switch.

B. PUMP WILL START BUT NOT PUMP

1. Water level too low - below the minimum suction level (Manual type).

2. Check to ensure strainer is not blocked.

3. Discharge tube clogged or obstructed.

4. 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 ).

5. Air bubble in the pump, produced during the plunge. Plunge the pump again,

at an angle, and shake it whilst lowering to remove any air trapped in the system.

6. Impeller may be damaged - Consult your CLARKE dealer

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.

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.)

2. Pump has run dry, or float switch has cut in.

3. A foreign object has jammed the impeller.
