When a footvalve is installed on installations that incorporate automatic pump control,
it is recommended that a suitable pressure relief valve be fitted in the discharge (outlet)
pipework from the pump.
ELECTRICAL INSTALLATION
WARNINGS:

The electrical installation must be carried out in accordance with the
current national electrical regulations by a competent person.

Before starting work on the electrical installation ensure the power
supply is isolated.

Where any of the pumps are installed in an area where there is a risk
of water spillage it is recommended that a residual current circuit
breaker having a rated current not exceeding 30 mA, be installed in
the supply circuit. This may be part of a consumer unit or a separate
unit.
 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 single phase 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.
When installing a 230V, 1 phase, pump in the United Kingdom, means for disconnection
must be incorporated in the fixed wiring according to the Wiring Rules. This can be done
by permanently connecting the pump to the mains supply via a double pole switched, fused
connection unit complying with BS 1363-4.
When installing a 110V, 1 phase pump it must be in accordance with the current electrical
regulations that apply to the installation.
All motors exceeding 370 watt output should be provided with control equipment
incorporating means for protection against overload.
The spur box (fused connection unit) or starter to which the pump is connected should
be mounted in an easily accessible position and labelled if confusion is possible to allow
easy isolation of the unit.
All pumps are continuously rated.
