8 ELECTRICAL INSTALLATION
• Regulations : The electrical installation must be carried out in
accordance with the current national electrical regulations and
installed by a qualified person.
• Safety : In the interests of electrical safety a 30 mA residual
current device ( R.C.D. not supplied ) should be installed in the
supply circuit. This may be part of a consumer unit or a separate
unit.
• Before starting work on the electrical supply ensure power
supply is isolated.
• DO NOT allow the supply cord to contact hot surfaces, including
the motor shell, pump body or pipework. The cord should be
safely routed and secured by cable clips.
• Adjacent pipes : Adjacent suction and delivery pipes should be
fitted with earthing clamps and connected with earthing wire
size 4 mm

• Earthing : This appliance must be earthed via the supply cord,
which must be correctly connected to the earth point located in
the terminal box.
• Pipework : Copper or metallic pipework must have
supplementary earth bonding where the continuity has been
broken by flexible hoses or plastic components.
• Additional earthing : Certain installations may require additional
earthing arrangements such as equipotential bonding. Reference
should be made to the relevant regulations concerning this
subject to ensure compliance.
