Electrical connection
The appliance complies with the CE Machinery Directive
89/392/EEC. The EC Low Voltage Directive 72/23/EEC
and the EC EMC Directive 89/336/EEC.
A 230V -50Hz mains electrical supply is required fused
externally at 5A.
The installation must continue to comply with:
United Kingdom:
- the national rules for electrical installations.
Ireland:
- the ECTI national rules for electrical installations
The appliance must be connected to an earthed socket.

When using an on/off thermostat or control, it is possible
that an anticipating resistance must be installed in order
to prevent too high temperature fluctuations. As a stand-
ard rule this means mercury thermostats. This resis-
tance wire is present in the Control Tower and must be
connected to clamps 23 and 27. The anticipating resis-
tance in the room thermostat has to be set at 0.11 A.
For more detailed questions regarding the components
which are not supplied, the country distributor should be
contacted.
All electrical connections must be done on
the connection block in the boiler.
