WATER CONNECTIONS

IMPORTANT: The pump must not be connected to the power supply until the

hose/pipe installation is completed.

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.

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

supplied as standard with your pump. However, accessories designed

specifically for this range of pumps are available from your CLARKE dealer

and are listed on page 10.

The pump must always be installed and operated in a horizontal position i.e.

with the outlet port facing upwards. The fixing holes in the base should be

used as necessary to secure the pump firmly in its operating position. Always

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.

These notes are for guidance on

how to achieve a good working

system.

The schematic diagram illustrates

a typical pipework installation.

The suction lift i.e. the vertical

distance between the water level

and the pump should not exceed

the distance specified for your

pump. (See Specification page 3)

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

illustrated below, so as to help retain water in the suction system and to

prevent the possibility of large foreign

bodies entering the pump body.

A 1" BSP hose adapter will be required for

connection to the inlet port. This is

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 strongly recommend that you use a

pipe which is as large a diameter as

practical, with a suitable reducer for

connection to the 1" BSP inlet port.
