Certain installations may require additional earthing requirements such as supplementary
equipotential bonding. Reference should be made to the relevant regulations concerning
this subject to ensure compliance.
Electrical Connection
The product range is provided with a factory fitted supply cord. This must be
permanently connected to the fixed wiring of the mains supply. Means for disconnection
must be incorporated in the fixed wiring in accordance with the wiring rules.
A suitable method of connection would be via a double pole switched, fused connection
unit complying with BS 1363-4, protected with a fuse (see fuse section).
The connection unit should be mounted in an easily accessible position and should be
labelled if confusion is possible, to allow easy identification of the pump isolating switch.
ELECTRICAL INSTALLATION
WARNINGS:
The electrical installation must be carried out in accordance with the
current national electrical regulations and installed by a competent
person.
In the interests of electrical safety a 30 mA residual current device
(R.C.D.) 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 installation ensure the power
supply is isolated.
This appliance must be earthed.
The motor and wiring must not be exposed to water.
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.
The standard pumps are suitable for a supply of 230V, 1 Phase, 50Hz. Other voltages
and frequencies are available on certain models and it is therefore very important to ensure
the voltage and frequency on the pump rating plate matches the supply.
Earthing
This appliance must be earthed via the supply cord.
Copper or metallic pipework must have supplementary earth bonding where the
continuity has been broken by flexible hoses or plastic components. Adjacent suction and
delivery pipes should be fitted with earthing clamps to BS 951 and connected with earthing
wire size 4 mm² (Fig. 11).
