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.
The pumps are rated for continuous use.
All motors exceeding 370 watt output should be provided with control equipment
incorporating means for protection against motor overload.
The pump is fitted with an integral on/off switch which is located on the pump terminal
box (Figs. 9 & 10).
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. 7). A standard kit is available from Stuart Turner (Part No.
17044).
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 pump is provided with a factory fitted supply cord and plug. This must be
connected to the mains supply via a 13 Amp double pole switched, socket outlet in
compliance with BS 1363-2.
The socket outlet 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.
Wiring
The moulded plug fitted to this appliance is not waterproof - keep dry.
The supply cord is factory fitted with a moulded plug incorporating a fuse, the value of
which is indicated on the pin face of the plug. Should the fuse need to be replaced, an
ASTA approved BS 1362 fuse must be used of the same rating, marked thus, . If
the fuse cover is detachable, never use the plug with the cover omitted. If a replacement
fuse cover is required, ensure it is of the same colour as that visible on the pin face of the
plug (i.e. red or orange).
