WARNING!

Before you get access to terminals, all supply circuits must be disconnected.

IMPORTANT

Where an appliance is installed in a room containing a bath or show-

er, the appliance and any electrical switch or any appliance control,

utilitising mains electricity should be situated specifically in accord-

ance with current IEE wiring regulations, Health & Safety document

cial procedures may be necessary. BS 6798 gives detailed guidance

on this aspect.

The appliance is supplied with a power supply cable (should the lat-

ter need to be replaced, use only original spare parts supplied by the

manufacturer).

It is advisable to carry out a check on the electrical system to ver-

ify conformity to the regulations in force. Verify that the electrical

system can suitably withstand the water heater's maximum power

consumption values (refer to the data plate), in terms of the size of

the cables and their conformity to the regulations in force.
