Electrical Wiring
1 An electrical supply must be available
which is correctly earthed, polarized and in
accordance with the latest edition of the IEE
requirements for electrical Installations BS 7671.
2 The electrical mains supply needs to be
230V/50Hz.
3 A means for disconnection from the supply
mains having a contact separation in all
poles that provides full disconnection
under over voltage category III conditions
must be incorporated in the fi xed wiring in
accordance with the wiring rules. This shall
be located within 1m of the appliance and
only serve the appliance.
4 An optional 3kW 230Vac immersion heater
complete with a thermostat and overheat
cutout with manual reset can be fi tted for
heating domestic hot water in case the
boiler fails. The immersion heater control
thermostat must be set at 75°C. The wiring of
the immersion heater must be in accordance
with the relevant IEE wiring regulations as
the circuit must be protected by a suitable
fuse and a local double pole isolator.
5 If an optional scale inhibitor device is
fi tted then a 3 core fl ex from the local 2-
pole isolator fused at 3A should be used
to connect 230Vac 50 hz supply to the
controller terminals (see fi gure 11).
6 The 230Vac 50hz supply to the system
wiring centre must be in accordance with
the relevant IEE Wiring Regulations on the
circuit must be protected by a suitable 5A
fuse and a double pole local isolating switch
(see fi gures 12 and 13)
