GENERAL SAFETY REQUIREMENTS
Domestic wiring must be tested periodically by a qualified electrician at least once
every 10 years or at every change of occupancy.
For office and retail premises, and buildings such as village halls, the wiring must
be inspected at least once every 5 years.
It is recommended that all buildings be fitted with smoke alarms (it is mandatory for
new buildings)
At time of going to press, the average cost of electricity is £0.13 per unit (kilowatt-
hour). The amount you are being charged will be shown on your electricity bill.
At this cost, the running costs will be as follows:
EH1550

These figures apply with the temperature programmed to its highest setting.
The running costs will be lower if programmed to a lower temperature, or if the
ambient temperature is higher.
Plug the mains lead into a 13 Amp mains socket.
If connecting via an extension lead, make sure that the lead is rated at 13 Amps,
and that it is fully unwound.
