5 ELECTRICAL INSTALLATION / EARTHING
5.11 Regulations: The electrical installation must be carried out in
accordance with the current national electrical regulations and
installed by a qualified person.
5.12 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.
5.13 Before starting work on the electrical supply ensure power supply is
isolated.
5.14
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.
5.15 Adjacent pipes: Adjacent suction and delivery pipes should be fitted with
earthing clamps in accordance with current regulations (Fig. 14).
5.16 Earthing: This appliance must be earthed via the supply cord.
5.17 Pipework: Copper or metallic pipework must have supplementary earth
bonding where the continuity has been broken by flexible hoses or plastic
components.
5.18
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.
5.19 Connections: The unit must be connected to a dedicated fused spur via a
lockable isolator to avoid authorized disconnection.
5.20 The electrical connection must be made adjacent to (not behind) the unit to
allow disconnection of the electrical supply should the pump module need to be
removed for service or maintenance.
