Thank you for purchasing this CLARKE Pump

Before using the device, please read this manual thoroughly and carefully follow

all instructions given. This is for your own safety and that of others around you, and

is also to help you achieve long and trouble free service from your new tool.

Your CLARKE CPE PUMP is a highly efficient, robust, continuously rated, self priming pump

with a powerful electric motor, and is ideal for a wide range of domestic, commercial and

agricultural uses.

It is suitable for pumping clean tap and rain water , and will handle small solids in suspension.

Your CLARKE CPE PUMP is designed to give you trouble free service provided it is installed

and used in the correct way.

Please follow these instructions carefully.

WARNING

CPE RANGE PUMPS ARE NOT SUBMERSIBLE PUMPS.

ON NO ACCOUNT MUST THEY BE IMMERSED IN WATER.

if the pump is left in an exposed position, it should be protected from the elements. especially

frost.

All electrical connections should be inspected regularly for signs of corrosion and cleaned

where necessary. It is advisable to apply a film of silicon grease on the terminals for added

protection.

Safety Precautions

•These pumps are designed to pump Water Only. NEVER use for pumping flammable

liquids or chemicals of any kind.

•ALWAYS ensure the pump is installed in a horizontal position with the outlet facing

vertically upwards, and that it is firmly anchored via its fixing screws.

•ALWAYS ensure there is an adequate air flow around the pump. DO NOT mount it

in an enclosed atmosphere.

•ALWAYS ensure all water pipes - supply or discharge, are adequately supported

where necessary, so as not to put a strain on the pump connections.

•ALWAYS ensure the inlet to the pump is completely unrestricted.

•ALWAYS ensure the pump is protected from the elements, neither the motor nor the

electrical terminal box is intended to be waterproof.

•ALWAYS ensure that all pipes are protected against damage where necessary,

and that they are suitably lagged to avoid the possibility of freezing during cold

weather.

•ALWAYS disconnect the pump from the electrical supply before any cleaning or

maintenance of the pump.

•NEVER allow the pump to run dry, as this will cause serious damage to the pump

seals.

•NEVER switch the pump ON when a swimming pool etc, is in use, i.e., when there is

person or animal in the pool.

WARNING:

As with all machinery, there are certain hazards involved with their operation

and use. Exercising respect and caution will considerably lessen the risk of

personal injury. However, if normal safety precautions are overlooked or ignored,

personal injury to the operator even damage to the pump or property, may

result. For your own safety and that of others around you, please read these

safety instructions in conjunction with the operating instructions, and before using

the pump.

Water Connections

IMPORTANT: The pump MUST NOT be connected to the mains supply until all hose/pipe

installation is completed. DO NOT RUN THE PUMP DRY

NOTE: If any part of the system is to be connected to the mains water supply, ensure that

local water authority regulations are observed.

Because of the variety of possible installations, no plumbing accessories are supplied with

your pump, however accessories designed specifically for this range of pumps is available

from your nearest CLARKE dealer.

The pump must always be installed and

operated in an upright position i.e. with the

outlet port facing vertically upwards. The

fixing holes in the base should be used as

necessary to secure the pump firmly in its

operating position. Also ensure there is

adequate air circulation around the motor.

Avoid situations where there is a risk of water

coming into contact with the outside of the

pump. Neither the motor or the terminal box

are designed to be waterproof.

These notes are for guidance on how to achieve a proper working system. The diagram

(Fig. 1) above shows a typical installation at the pump.

A foot valve and filter should be fitted to the lower end of the suction hose, as illustrated in

Fig. 2, so as to retain water in the suction system and more importantly, to prevent the

possibility of large foreign objects entering the pump body.

The performance of your pump will be affected by the diameter of

the inlet pipe - any restriction will greatly reduce the flow. We strongly

recommend that you use a pipe diameter as large as practicable.

A gate valve may be installed in-line on the delivery side (Outlet Port)

of the pump which can be adjusted as required to regulate the flow

of water, it can also assist in priming the pump.

WARNING DO NOT place any such obstruction on the suction side

(inlet Port) of the pump unless it is an isolator valve in a gravity fed

system. It is also IMPORTANT to note, that these pumps should not be

operated with the delivery valve completely closed.

To prevent unnecessary strain or possible distortion to the pump, ensure

that adequate support is provided to the hoses and or pipes. They will

be considerably heavier when filled with water.

Should contaminants come into contact with the pump, flush through with cold water as

soon as possible to prevent damage to the pump.

Protect the pump and pipework from freezing. The formation of ice may cause serious

damage.

Where the pump is to be a permanent fixture, the fittings to the pump MUST be flexible, i.e.

a short piece of hose should be inserted between the rigid pipework and the pump.

Electrical Connection

Wiring Connections For Three Phase Models

Again installation should be carried out by a qualified electrician, using I.E.E cable and

fittings, and in accordance with I.E.E Regulations. To connect the cable to the motor see

electrical connections inside the terminal cover.

Single phase pumps should be connected to a standard domestic 13 amp, 230 volt (50Hz),

electrical supply, we strongly recommend that the connection be made via a suitable

isolator switch and Residual Current Device (RCD).

IMPORTANT: Should the supply be taken from a normal 13 amp socket, then the plug used

must be to BS 1363 standard, and the wires should be wired up in accordance with the

following colour code:

Green & Yellow ............... Earth or marked with a letter “E” or Earth symbol “ ”.

Blue ................................... Neutral or terminal marked with a letter “N”

Brown ............................... Live or terminal marked with a letter “L”

WARNING: THIS PUMP MUST BE EARTHED.

Before connecting the pump, check the voltage and phase supply required, this information

can be found on the junction box cover on top of the motor.

Installation should be carried out by a qualified electrician, using I.E.E approved cable and

fittings, and in accordance with I.E.E. Regulations. However, in the further interests of safety

we would emphasise the following,

IF IN ANY DOUBT, contact CLARKE International Service on 020 8988 7400

Maintenance

No regular maintenance is required other than regular inspection to ensure that leaves

and other particles are not covering the suction inlet, also check the pump for signs of wear

or damage.

If any signs of wear or damage are found, contact your nearest Clarke dealer.

If you suspect that your pump is blocked by mud, silt , leaves etc, disconnect from

the mains supply and backflush. This should dislodge any blockage and aid cleaning.

Trouble Shooting

The pump does not run 1. No mains supply 1. Check fuse - replace if

necessary (Check fuse rating).

2. Impeller seized / blocked 2. Disconnect pump from mains,

investigate cause and clear

blockage etc..

Pump runs but no output 1. Air in pump housing 1. Disconnect from the mains and

check all hose connections

are air tight etc.

2. Suction height too great 2. Check height is within spec. for

your pump, (see specs page 2).

Low or no Flow 1. Blocked inlet pipe 1. Check to see that no foreign

matter is fouling the intake

system and check the filter is

not blocked or obstructed.

2. Head too high 2. Check that head is within spec.

there is little likelihood of problems arising, but if water will not flow as it should then check

the following points:-

Should you still experience problems, then contact your Clarke dealer, or CLARKE

International Service Department for advice.

Maintenance

Once the pump is installed, it is maintenance free, however, if it is anticipated that

it will not be used for a long period - 3/4 months or so, it should be flushed completely

with clean water to avoid the possibility of scale build up. This will entail

disconnection from the system and pouring clean water into the outlet and reverse

flushing. If this happens regularly, it is recommended that gate valves be installed

close to the pumps inlet and outlet ports.
