WARNING: READ THESE ELECTRICAL SAFETY INSTRUCTIONS
THOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE MAINS
SUPPLY.

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.

This product may be fitted with a non-rewireable plug. If it is necessary to
change the fuse in the plug, the fuse cover must be refitted. If the fuse cover
becomes lost or damaged, the plug must not be used until a suitable
replacement is obtained.

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.

WARNING: THE WIRES IN THE POWER CABLE OF THIS PRODUCT ARE
COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE:
BLUE = NEUTRAL BROWN = LIVE YELLOW AND GREEN = EARTH

The colours of the wires in
the power cable must
agree with the markings on
the plug.

• Connect the BLUE wire

to the terminal
marked N.

• Connect the BROWN

wire to the terminal
marked L.

• Connect the YELLOW

AND GREEN wire to the terminal marked E or .

AN APPROVED RESIDUAL CURRENT DEVICE (RCD) WHICH HAS A TRIPPING
CURRENT OF LESS THAN 30 mA MUST BE USED.

If you are not sure consult a qualified electrician.

INSTALLATION OF THE PUMP

IMPORTANT: The pump MUST NOT be connected to the mains power supply
until all hose/pipe installations are completed.

These notes are for guidance on how to achieve a proper working system. If
any part of the system is to be connected to the mains water supply, ensure
that you comply with your local water authority regulations.

INSTALLATION LAYOUT

The pump must always be installed and operated in a horizontal position using
the fixing holes in the base to secure the pump firmly in its operating position.
Ensure that there is adequate air circulation around the motor.

Avoid situations where there is the risk of water coming into contact with the
outside of the pump. Neither the motor or the terminal box are designed to be
waterproof.

The suction lift i.e. the vertical distance between the water level and the
pump, should not exceed the distance specified for your pump.

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 any rigid metal
pipework and the pump.

To prevent unnecessary strain or possible distortion to the pump, ensure that
adequate support is provided to the hoses and/or pipes. Remember they will
be considerably heavier when filled with water.

PIPELINE FITTINGS REQUIRED

Because of the variety of possible installations, no plumbing accessories are
supplied. However, accessories designed specifically for this range of pumps
are available from your CLARKE dealer.

The performance of your pump will be effected by the diameter of the inlet
pipe - any restriction will greatly reduce the flow. We recommend that you use
a diameter which is as large as practicable with a suitable reducer for
connection to the 1” BSP inlet adapter. The discharge hose should be
attached to the outlet adapter (not supplied).

A 1” BSP hose adapter will be required for connection to the inlet and outlet
port. These are available from your CLARKE dealer.

A gate valve may be installed in-line on the outlet side of the pump which can
be set as required to regulate the flow of water. Do not place any such
restriction on the suction side of the pump unless it is an isolator valve in a
gravity fed system.

PREPARATION FOR USE

PRIMING THE PUMP

When suction lift is used to draw water into the pump it is essential that all
connections and hoses are completely air tight or the system will not work.

Although the pump is a ‘self priming’
type, it is still necessary to completely
fill the inlet side of the pump with
water before being started for the
first time or if the system has been
drained for maintenance/repair. This
is carried out as follows:-

1. Remove the filler plug on the top
of the pump chamber and fill the
pump with water until all air is
expelled.

NOTE: If a filter is fitted to your pump it is recommended that you remove

the brass plug on top and fill the filter bowl with water.

2. Adjust any valves which may be fitted to the outlet side of the pump so as
to ensure as great a flow as possible.

3. Switch on the pump and check for leaks. Water should quickly start to flow
through the system. If, depending upon the suction depth, water does not
flow, check to ensure:

• The inlet pipe is secure and free from defects. Even a pin hole could

prevent the pump from drawing water efficiently. This is the most
common problem encountered when operating water pumps.

• The pump body has been primed correctly and is completely filled

with water.

NOTE: If the pump is gravity or pressure fed, priming will not be necessary

as the pressure of water will purge the system of air.

It is essential that all connections and hoses are completely air tight or the
system will not work effectively.

The pump should never be operated with any delivery valve completely
closed.

CARE AND MAINTENANCE

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

The only maintenance required is a regular inspection to ensure that debris is
not blocking the passage of water through the pump. Should sediment,
chemical or other contaminants come into contact with the pump, flush
through with cold clean water as soon as possible.

If you suspect the pump is blocked by debris etc, disconnect it from the power
supply and back-flush to clear any blockage using a garden hose.

• You will need to disconnect the outlet hose to do this.

Always keep the pump in a clean condition, checking regularly for loose
fastenings or a damaged power cable etc.

The pump should not be taken apart by the user if overhaul is required, but
should be taken to your nearest CLARKE dealer for repair.
