Electrical Connection

The pump is provided with a factory fitted supply cord. This must be permanently 

connected to the fixed wiring of the mains supply. Means of disconnection must 

be incorporated in the fixed wiring in accordance with the current electrical wiring 

regulations. A double poled switched, fuse connection unit is suitable for this purpose. 

This switch must comply with BS1363-4, protected with a 5 Amp fuse and should 

be mounted in an easily accessible position. The switch should also be labelled, 

particularly when located near to any other electrical isolating switches.

1.

 

The electrical installation must comply to "BS 7671 (commonly referred 

to as the IEE Wiring Regulations) and all relevant building regulations, or 

any particular regulations or practices specified by the local electricity 

supply company. The installation must be carried out by a competent 

person.

2. 

In the interests of electrical safety, a 30 mA Residual Current Device 

(RCD) is recommended to be installed in the supply circuit. This may 

be part of the consumer unit or a separate unit.

3. 

Before starting work on the electrical installation, make sure the power 

supply is isolated.

4. 

This appliance must be earthed.

5. 

The motor and wiring must not be exposed to water.

6. 

Do not allow the supply cord to come in contact with any hot surfaces, 

including the motor housing, pump body or pipework. The cord should 

be safely routed and secured with suitable cable clips.
