Means of disconnection from the supply having at least 3mm contact separation in both poles must be
incorporated in the fixed wiring.

We recommend a separate fused circuit from the consumer unit (24 Hour supply) protected by a 15
amp HRC fuse or, preferably a 16 amp MCB. In some cases immersion heater failure can damage the
Electrisaver. Installation of a 100 mA RCD will provide additional protection for the unit. If the
Electrisaver is to be connected to a ring main then the spur feeding the controller should be
protected in the same way.

The Electrisaver is NOT suitable for mounting on an unearthed metal surface.

To use the Electrisaver simply press the BOOST button in quick succession until the indicator light for
the required boost period is illuminated (see table below).

To cancel a boost period press the BOOST button continuously until ALL the indicator lights are OFF.

Keeping the boost button depressed will cancel any Boost period.

When the Boost is activated the indicator light will ‘countdown’ showing the approximate duration of
the Boost period remaining.

Use twin and earth cable with a minimum conductor size of 2.5mm2to connect the Electrisaver to the
supply. Use a suitably rated three-core flexible cord (see below) to connect the Electrisaver to the
appliance to be switched.

For appliances up to 2Kw rating use minimum 1.0mm

2

conductors.

For appliances up to 3Kw rating use minimum 1.5mm

2

conductors.

Heat resistant flexible cord must be used if connection the Electrisaver to an immersion heater.
Connections to the Electrisaver terminal block should be as follows:-

NN iinn == NNEEUUTTRRAALL iinn
NN oouutt == NNEEUUTTRRAALL oouutt ttoo aapppplliiaannccee
LL iinn == LLIIVVEE iinn
LL oouutt == LLIIVVEE oouutt ttoo aapppplliiaannccee

Remove cut-outs before fixing the box. Where appropriate drill the box to provide close fitting entry
for cables and heat-resistant flexible cords. Take care to remove sharp edges.
All un-insulated earth conductors must be sleeved and connected to the earth terminals on the back
of the Electrisaver.

Clamp all surface wiring to the wall adjacent to the Electrisaver or use trunking where appropriate.
The flexible cord to the appliance should be passed through the cable entry hole in the bottom edge
of the Electrisaver, and secured under the cable clamp provided.

Ensure that the clamp is positioned the right way up ie. the projections on the underside of the clamp
should grip the cord in order to secure the cable firmly, the cable clamp screws must be adequately
tightened.

Carefully offer the Electrisaver to the moulded/metal box and secure using two M3.5 captive screws
provided. Do not damage insulation or trap the conductors during this operation.
Finally switch on the mains supply, ensure the Electrisaver operates correctly.
