INTRODUCTION

Thank you for purchasing this CLARKE submersible pump designed for

pumping/grinding waste water containing light slurry or sewage.

The CLARKE range of submersible pumps are suitable for discharging pools,

ponds, fountains, pits and any waste water drainage. They can handle foul

water containing suspended material as listed in the specification. The pumps

are not suitable for handling inflammable, corrosive, explosive or dangerous

liquids.

The ‘Pump Performance Curve’ graph shown, displays the characteristics

graphically and describes the relation between the flow-rate and the head

for the pump.

The pump is provided with a thermal overload cut-out, so that in the event

that the pump becomes overheated (due to becoming blocked etc) it will

shut off automatically. When the blockage has been cleared, the thermal

cutout will cool down and re-set and the pump can be re-started.

Before attempting to use this product, it is essential that you read this manual

thoroughly and carefully follow all instructions given. In doing so you will ensure

the safety of yourself and that of others around you, and you can also look

forward to the product giving you long and satisfactory service.

collapse.

11. NEVER modify the pump in any way. Use it only for the purpose for which it

is designed.

12. NEVER allow the pump to run dry or operate out of the water.

13. Submersible pumps should always be submerged and stored vertically.

14. Disconnect the pump from the mains supply before placing it into or

removing it from the water.

15. NEVER insert your fingers into the pump whilst it is connected to the mains.

16. Keep the pump clear of any sediment by standing it on a platform or brick

or suspending it at a suitable depth.

17. DO NOT use the pump if the water is liable to freeze, as this can cause

damage to the pump. Remove the pump from the water and store it in a

frost free location.

ELECTRICAL CONNECTIONS

Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply

through an approved 13 amp BS 1363 plug, or a suitably fused isolator switch.

If the plug has to be changed because it is not suitable for your socket, or

because of damage, it must be removed and a replacement fitted, following

the wiring instructions shown below. The old plug must be discarded safely, as

insertion into a power socket could cause an electrical hazard.

If the colours of the wires in the power cable do not agree with the markings

on the plug proceed as follows.

• The BLUE wire must be

connected to the

terminal marked N or

coloured black.

• The BROWN wire must

be connected to the

terminal marked L or

coloured red.

• The YELLOW AND

GREEN wire must be

connected to the

terminal marked E or

or coloured green.

AN APPROVED RESIDUAL CURRENT DEVICE (RCD) WHICH HAS A TRIPPING

CURRENT OF LESS THAN 30MA MUST BE USED.

CONNECTION AND POSITIONING

Remove all packaging and make sure that the unit contains no visible

damage. Dispose of all packaging appropriately.

CONNECTING THE PUMP

1. Connect the outlet adaptor to the hose.

• The adaptor fitting allows for connection of 32 mm (1¼”), hoses which

should be secured with a hose clamp.

2. If a long run of discharge hose is being used, any restriction will reduce

capacity and put unnecessary strain on the motor

• Suitable hoses are available from your local CLARKE dealer.

POSITIONING THE PUMP

1. It may be safer to raise and lower the pump into deep water using a rope

attached to the lifting handle.

2. Place the pump in a vertical position resting on a firm, flat surface in the

area that you want to drain. If there is sediment in the operating area, the

pump should be placed vertically on house bricks, or similar but ensure

they are not likely to collapse. Never position the pump on sand, silt, mud

or ground which is likely to collapse.

3. Keep the pump clear of sediment by standing it on a platform or brick or

suspending from a rope attached to the handle if the pump is to be used

where there may be silt or mud etc (e.g. garden ponds).

4. Route the hose as straight as possible. Excessive bending of the hose could

obstruct the flow of water, reduce the pumping volume or clog the pump

with mud, thus disabling the pumps function. If the hose is kinked at its base

it will create air pockets in the pump, causing it to operate in a partially dry

state. Take care to straighten any kinks or bends in the hose.

5. DO NOT operate the pump if the water is too shallow. This will be below the

level of the outlet elbow with the impeller fully immersed.

6. Allowance must also be made for the overall width of the pump including

the outlet elbow on one side.

• When the pump is being used in a permanent or semi-permanent

installation, a non-return valve should be fitted in the delivery hose.

Suitable hoses and valves are available from your CLARKE dealer.

• Take all necessary safety precautions as described on pages 4-6.

• The pump inlet must be fully submerged before being switched on.

USING THE PUMP

1. Plug in the pump and switch on the power supply.

• The pump will begin to drain water.

2. Run the pump continuously or remove from the water and store in a frost

free location if the water is likely to freeze.

3. Ensure the pump is switched off when water has stopped flowing.

• The pump should be able to clear water down to a residual depth of the

inlet port, In this situation, air and residual water may be seen escaping

from the discharge hose.

4. Disconnect from the power supply when the water has been pumped out.

Avoid running the pump continuously if the discharge hose has become

obstructed and water is not flowing.

5. DO NOT ALLOW THE PUMP TO RUN DRY

6. Disconnect the pump from the mains supply before placing it into or

removing it from the water.

7. NEVER insert your fingers into the pump whilst it is connected to the mains.

8. DO NOT use the pump if the water is liable to freeze, as this can cause

damage to the pump. Remove the pump from the water and store it in a

frost free location.

OVERLOAD PROTECTION

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 at the mains supply. Check for blockages and allow the

motor to cool (at least 5 minutes) by which time the cut-out will have reset.

Once the pump has cooled the pump will automatically restart.

WARNING: CHECK THE PUMP FOR DAMAGE BEFORE USE, DO NOT USE THE

PUMP IF IT IS DAMAGED IN ANY WAY.

CLEANING, MAINTENANCE & STORAGE

The pump should require no maintenance other than regular cleaning.

1. Inspect the pump prior to use and do not use the pump if there is any

damage to the mains power cable.

2. Check pump regularly to ensure the inlet is clear of leaves or other debris. It

can be cleaned out either by back-flushing or by cleaning out by hand.

Take extra care to remove any debris from around the impeller.

3. If the pump has been used for pumping swimming pool water or salty

water likely to leave chemical residues, it should be flushed through with

clean water before storage.

4. When the pump is not being used for extended periods, clean and dry it

thoroughly and store in indoors. if the pump is left in water, it should be run

at least once a week to prevent it from seizing up.

5. If the pump shows signs of wear or damage, contact your CLARKE dealer

for advice. Do not attempt to repair the pump yourself, as you may

damage the waterproof seals and invalidate your guarantee. Repairs

should be carried out by your local CLARKE dealer, or contact the CLARKE

Service Department on 020 8988 7400.

WARNING: MAKE SURE THAT THE PUMP IS DISCONNECTED FROM THE

POWER SUPPLY BEFORE CLEANING OR PERFORMING MAINTENANCE
